1540-711: A port or nearby. Modern ports will have specialised cargo -handling equipment, such as gantry cranes , reach stackers and forklift trucks . Ports usually have specialised functions: some tend to cater mainly for passenger ferries and cruise ships ; some specialise in container traffic or general cargo; and some ports play an important military role for their nation's navy. Some third world countries and small islands such as Ascension and St Helena still have limited port facilities, so that ships must anchor off while their cargo and passengers are taken ashore by barge or launch (respectively). In modern times, ports survive or decline, depending on current economic trends. In

Sewage from ships, and leaks of oil and chemicals from shipping vessels can contaminate local water, and cause other effects like nutrient pollution in the water. Ports and their infrastructure are very vulnerable to climate change and sea level rise, because many of them are in low-lying areas designed for status quo water levels. Variable weather, coastal erosion, and sea level rise all put pressure on existing infrastructure, resulting in subsidence , coastal flooding and other direct pressures on

Rye, East Sussex , was an important English port in the Middle Ages, but the coastline changed and it is now 2 miles (3.2 km) from the sea, while the ports of Ravenspurn and Dunwich have been lost to coastal erosion . Whereas early ports tended to be just simple harbours, modern ports tend to be multimodal distribution hubs , with transport links using sea, river, canal, road, rail and air routes. Successful ports are located to optimize access to an active hinterland , such as

According to ECLAC 's "Maritime and Logistics Profile of Latin America and the Caribbean", the largest ports in South America are the Port of Santos in Brazil, Cartagena in Colombia, Callao in Peru, Guayaquil in Ecuador, and
10500-488: The UK, both the ports of Liverpool and Southampton were once significant in the transatlantic passenger liner business. Once airliner traffic decimated that trade, both ports diversified to container cargo and cruise ships. Up until the 1950s the Port of London was a major international port on the River Thames , but changes in shipping and the use of containers and larger ships have led to its decline. Thamesport ,
10640-551: The Wuhan and Nanjing factional governments, who both sought his aid. He met with Wang Jingwei and Tang Shengzhi at Zhengzhou on 10–11 June, then travelled to Xuzhou to meet with Chiang Kai-shek on 19 June. On the next day, Feng announced that he would align with the Nanjing faction and purge communists from the areas under his control, crippling the Wuhan government's plan to push north, upon which Tang returned to Wuhan with his troops. Whilst Chiang intended to push into Shandong, he
10780-412: The Wuhan and Nanjing factions. As the two sides attempted to reconcile their political differences, Sun Chuanfang's forces continued to bombard Nanjing from across the Yangtze. Sensing the NRA's continual disarray, Sun moved to try and recapture Shanghai, contrary to the wishes of NPA leader Zhang Zuolin. On 25 August, NPA landing parties were dispatched to cross the Yangtze at Longtan, near Nanjing. In
10920-415: The Wuhan government was dissolved, with a new joint government established in Nanjing, under the leadership of Guangxi clique generals. Wang Jingwei refused to join the new government, as did Tang Shengzi, who became an independent warlord in his own right, controlling Hubei, Hunan, Jiangxi, and parts of Anhui. On the other hand, Shanxi warlord Yan Xishan, theretofore independent, aligned his province with
11060-583: The Yangtze was referred to as "the Chicago of China" by the media back then. In 1926, Hankou was officially established as a city, where its municipal government was built in Jianghan district . In the same year, the Northern Expedition reached Hankou, and merged Hankou with adjacent Wuchang and Hanyang to make it the seat of the national capital, Wuhan. But in 1927, when Nanjing succeeded in
11200-438: The Zhejiang border, with the NPA protecting his rear, and charged into Zhejiang, retaking most of the province. By 10 January, the majority of the Zhejiang rebel forces had retreated to Quzhou . To relieve the besieged rebels, He Yingqin pushed his Fujian-based forces into Zhejiang, halting Sun's advance. The rebel and KMT forces merged under the command of Bai Chongxi , who launched a counteroffensive on 20 January. By 29 January,
11340-479: The aftermath of the coup, Chiang negotiated a compromise whereby hardline members of the rightist faction, such as Wu Tiecheng , were removed from their posts in compensation for the purged leftists. By doing so, Chiang was able to prove his usefulness to the CCP and their Soviet sponsor, Joseph Stalin . Soviet aid to the KMT government would continue, as would co-operation with the CCP. A fragile coalition between KMT rightists, centrists led by Chiang, KMT leftists, and
11480-488: The aim of seeking aid from the powerful Fengtian clique. Shandong warlord Zhang Zongchang and Manchurian warlord Zhang Zuolin offered assistance, agreeing that it was necessary to contain the NRA, though they demanded payment in return for their help. As the NRA offensive carved its way through Fujian, 60,000 troops from Shandong arrived in Sun-controlled Anhui province on 24 November. These were organised into
11620-466: The allegiances of Wang Jingwei, who had been based in Guangzhou after the end of the Wuhan government. Wang left for exile in France on 17 December, paving the way for Chiang's return as commander-in-chief. With the military success of Chiang's Whampoa troops, the various KMT factions agreed to recognise the legitimacy of Chiang's leadership. Consequently, Chiang was officially invited to resume command of
11760-578: The alliance between the nationalists and the Communists and the First United Front. Though, the ensuing White Terror devastated the Communists, and only 10,000 out of 60,000 party members survived. The purge was condemned by Wang Jingwei, now leader of the Wuhan government, formalising the split between the KMT leftists based in Wuhan and the KMT rightists, who subsequently established their own government in Nanjing. The precariousness of
11900-404: The area, Meng Chao-yueh , decided on 17 February to abandon Hangzhou and flee with his 20,000 troops by train to Jiangsu province. By 23 February, Zhejiang was under complete KMT control.

Aided by the defection of numerous warlords and their armies, by this point,
12040-479: The balance. In other words, it is a struggle between the nation and the warlords, between the revolution and the anti-revolutionaries, between the Three People's Principles and imperialism.

With the capture of the Yangtze port of Yuezhou on 22 August, Hunan came under complete KMT control, paving
12180-445: The capture of Beijing, Chiang and his administration moved quickly to reorganise the government for peacetime. In July, he and the leaders of the four collective armies met at Beijing to discuss the demobilisation and disarmament of the roughly 2.2 million troops that had come to be part of the NRA. Chiang desired to reduce the size of the army by half, so as to free up government monies for domestic development. The lack of unity in
12320-455: The central government, in an effort to curtail the provincialist tendencies of the warlord era. Minister of Finance T. V. Soong called for all revenues to be centralised in the national treasury. In the end, though, it was recognised that real centralisation could only occur if the various commanders, the former warlords, relinquished their financial and military power to the national government. While these principles were nominally agreed to by
12460-533: The cities themselves. Even though modern ships tend to have bow-thrusters and stern-thrusters, many port authorities still require vessels to use pilots and tugboats for manoeuvering large ships in tight quarters. For instance, ships approaching the Belgian port of Antwerp , an inland port on the River Scheldt , are obliged to use Dutch pilots when navigating on that part of the estuary that belongs to
12600-528: The city undefended. Cheng arrived the next day, entering the city with no resistance. Almost immediately after arrival of the NRA, mass anti-foreigner riots broke out in the city, in an event that came to be known as the Nanjing Incident .

The flight of some missionaries from the T'ai-yüan massacre in Shan-si is recorded in the work A Thousand Miles of Miracle in China , by Reverend A E Glover, one of the fleeing missionaries. On 10 October 1911, a revolution to establish
13160-413: The cruise ship is in port, because off-going passengers debark their baggage and on-coming passengers board the ship in addition to all the supplies being loaded. Cruise home ports tend to have large passenger terminals to handle the large number of passengers passing through the port. The busiest cruise home port in the world is the Port of Miami , Florida . A port of call is an intermediate stop for
13300-460: The culmination of tensions within the First United Front. The nationalist government had moved from Guangzhou to the new city of Wuhan , which was formed from a merger of Wuchang and two other nearby cities. The Wuhan administration gradually drifted away from Chiang, becoming a centre of leftist, Soviet-backed power within the KMT and constraining his authority. Communist-led trade unions staged near-constant demonstrations in Wuhan itself, and across

13580-579: The early morning of 26 August, thousands of Sun's troops crossed the river, rallying at the Longtan station of the Shanghai–Nanjing railway. Li Zongren's NRA Seventh Army managed to drive the NPA away from the railway briefly, but thousands more of Sun's troops, including White Russian mercenary units, crossed the river the next day and retook the station, cutting off contact between Nanjing and Shanghai. The reeling NRA sent missives to all factions within
13720-445: The end of October, Sun's forces were again in retreat across Jiangxi and Fujian. In early November, KMT troops moved to capture the Yangtze ports of Jiujiang and Hukou , and by 9 November, retook control of Nanchang.

Concurrently, Sun himself had left for Tianjin with
13860-423: The fight to be the national capital, Wuhan was returned to its original form, with Hankou being again a city by itself. This time Hankou was established as a "Special Municipality," which resembles a direct-controlled municipality in present day.

Zhang, weary of KMT propaganda that linked him with
14140-481: The forces of the "Young Marshal" Zhang Xueliang , Zhang Zuolin's son and political heir, pushing them back to a river at Yancheng . By 20 May, Li had captured Bengbu, whilst Chiang unleashed a four-pronged attack through Jiangsu, toward the warlord power base in Shandong. He Yingqin led the NRA First Army across the Yangtze at Zhenjiang , and moved to capture Haizhou . On 28 May, Li took Suzhou , while
14280-441: The front. These orders had no effect, as Wuhan had almost no military authority. The government intended to send a small force to Nanjing with the aim of "disarming" Chiang, but put that plan on hold following Wang Jingwei 's return from exile in Europe. Wang, who had travelled back to China at the urging of members of the government, was greeted in Shanghai by Chiang, who offered a power-sharing deal. Wang said that he would consider
14420-544: The goal of reunifying China. This preparation involved improving both the political and military strength of the KMT. Before his death in March 1925, Sun Yat-sen , the founder of the Republic of China and co-founder of the KMT, was supportive of Sino-Soviet co-operation , which had involved forming the First United Front with the Chinese Communist Party (CCP). The military arm of the KMT
14560-520: The leader of the Fengtian clique, and in December 1928, announced that Manchuria would accept the authority of the nationalist government in Nanjing. With the final piece of China under KMT control, the Northern Expedition concluded successfully and China was reunified, heralding the start of the Nanjing decade . In the 1920s, the Beiyang government based in Beijing was internationally recognised as
14700-570: The legitimate Chinese government. Much of the country, however, was not under its control, being ruled by a patchwork of warlords . The Kuomintang (KMT), based in Guangzhou (Canton), aspired to be the party of national liberation.

14980-776: The nationalists, Zhang Zongchang declared war on the Fengtian clique. Supported by Japan, the Shandong–Zhili Army moved from its base at Tangshan on 2 August, crossed the Luan River , and invaded Manchuria. After six days of fighting, however, the defiant warlord army was trapped by KMT and Zhang Xueliang-aligned forces; many of Zhang Zongchang's troops (including the White Russian mercenaries) defected or deserted, and those who refused to surrender were killed. Chinese Nationalist forces captured an armoured train of Russian mercenaries serving Zhang Zongchang and brutalized
15120-403: The new administration quickly became apparent, and on 14 July, Feng Yuxiang left Beijing. A general meeting of the KMT was held in Nanjing from 8–14 August. At this meeting, also attended by non-KMT members Feng and Yan Xishan, the primary topic of discussion was that of centralisation. Chiang desired to take the power that had been executed through various provincial entities and concentrate it in
15260-589: The next day, Cheng and He were finally able to put an end to the violence. Chiang Kai-shek's faction accused Lin Boqu of planning the unrest, viewing it as an attempt to turn international opinion against the KMT. Lin, a member of both the CCP and the KMT, had been serving as political commissar of the Sixth Army, part of Cheng Qian's forces. Whoever was responsible, the Nanjing Incident represented
15400-413: The next day, NRA troops entered Jinan. Chiang Kai-shek arrived on 2 May, and attempted to negotiate a Japanese withdrawal from Jinan, issuing safety guarantees for Japanese civilians to local Kwantung Army commander Hikosuke Fukuda . Fukuda agreed, and his troops prepared to leave that night. Early the next morning, conflict broke out between the Chinese and Japanese troops, starting what came to be called
15540-477: The next phase of the conflict. Launching a counteroffensive on 3 April, the NPA had been able to force the NRA back more than 161 kilometres (100 mi) to the Yangtze by 11 April.

He's forces moved up the coast, pushing toward the provincial capital, Fuzhou . By
16380-465: The recently allied forces of the Fengtian and Zhili cliques, the nationalist government appointed Chiang Kai-shek commander-in-chief of the NRA on 5 June 1926.

Accordingly, in an attempt to put pressure on Sun, Feng Yuxiang and his Guominjun launched an attack into Shandong on 28 August, while Wuhan sent its troops north, trying to flank Sun, and He Yingqin approached from Shanghai. With its forces encircled, and unable to continue to move troops across the river, the NPA
16800-480: The revolutionary troubles that accompanied the Northern Expedition when the Chinese Kuomintang forces occupied the concession and showed no intention of withdrawing. The Chen-O'Malley Agreement of February 1927 provided for a combined British-Chinese administration of the concession and in 1929 the British concession formally came to an end. From then on it was administered by the Chinese authorities as
16940-645: The scarcity of food and total lack of shelter left the vast horde without any idea of further resistance". The Japanese, meanwhile, having heard of Sun's defeat, began to move Kwantung Army troops by train from Qingdao to Jinan. While the NRA Second Collective Army advanced northeast to Jinan along the southern bank of the Yellow River, the First Collective Army diverged east from the Tianjin–Pukou railway at Tai'an , crossing
17080-479: The still ongoing Canton–Hong Kong strike, which continued to hamper his supply chain. Negotiations with the British began on 23 September, with the strike finally called off on 10 October. This eased access to supplies for the NRA, and freed up manpower, in the form of the strikers, for the continued push north. On the same day, Wu Peifu's remaining forces at Wuchang surrendered, completing the NRA's conquest of Hubei province. As bloody fighting continued in Jiangxi,

17500-539: The terminus of the Alaska Pipeline owe their very existence to being ice-free ports. The Baltic Sea and similar areas have ports available year-round beginning in the 20th century thanks to icebreakers , but earlier access problems prompted Russia to expand its territory to the Black Sea . A dry port is an inland intermodal terminal directly connected by road or rail to a seaport and operating as
17640-414: The walled city held out for over a month. His failure in the face of the NRA, however, left his hold on power and reputation broken. What remained of his army would disintegrate in the following months.

By 28 August, the KMT, led by Li Zongren and his Guangxi NRA Seventh Army, had taken Xianning , about 75 kilometres (47 mi) south of Wuchang. Wu Peifu, who had returned south to mount a defence of Wuchang, gathered his forces at Heshengqiao Bridge. On 29 August, he launched
18060-766: The world's ports have somewhat embedded technology, if not for full leadership. However, thanks to global government initiatives and exponential growth in maritime trade, the number of intelligent ports has gradually increased. A report by business intelligence provider Visiongain assessed that Smart Ports Market spending would reach $ 1.5 bn in 2019. Ports and their operation are often a cause of environmental issues, such as sediment contamination and spills from ships and are susceptible to larger environmental issues, such as human caused climate change and its effects. Every year 100 million cubic metres of marine sediment are dredged to improve waterways around ports. Dredging, in its practice, disturbs local ecosystems, brings sediments into
18200-413: Was almost immediately forced to withdraw back to Zhejiang; Sun had detected Xia's plans days earlier. Sun's forces subsequently marched on Zhejiang, crushing the rebellion by 23 October.

The Second Collective Army consisted of Feng's Guominjun , the Third of Yan's Shanxi forces, and the Fourth of Li Zongren's Guangxi clique army. By this point, the NRA was made up of one million soldiers, most of them part of ex-warlord armies. Preparing for
19320-759: Was the National Revolutionary Army (NRA). Chiang Kai-shek , who had emerged as Sun's protégé as early as 1922, was appointed commandant of the Whampoa Military Academy in 1924, and quickly emerged as a contender for the position of Sun's successor in the aftermath of his death. On 30 May 1925, Chinese students in Shanghai gathered at the International Settlement , and held demonstrations in opposition to foreign interference in China. Specifically, with
19460-600: Was thwarted by the arrival of the Japanese Kwantung Army during the course of June, who were ostensibly deployed to protect Japanese citizens in Qingdao . Around this time, Wu Peifu retreated with his remaining forces into Sichuan, where he announced his retirement. On 5 July, NPA general Chen Yi-yen defected to the NRA, but failed to convince his 10,000 soldiers at Qingdao to do likewise. At Wuhan, Tang Shengzhi began to mobilise his troops for an attack on
