Chalk streams are rivers that rise from springs in landscapes with chalk bedrock . Since chalk is permeable , water percolates easily through the ground to the water table and chalk streams therefore receive little surface runoff . As a result, the water in the streams contains little organic matter and sediment and is generally very clear.
63-729: The River Mimram is a chalk stream in Hertfordshire , England. It runs from its source near Whitwell in Hertfordshire to join the River Lea at Hertford. The River Mimram rises from a spring to the north-west of Whitwell , in North Hertfordshire , England . At Whitwell there are watercress beds which have existed since Roman times and these are fed by the same springs. The valley extends northwards where it becomes known as Lilley Bottom . Other sections of
126-480: A Celtic deity, though no academic sources have been cited for this and the speculation probably stems from a comparison with etymology for the nearby River Beane . Generally, etymologists and philologists have found the name 'Mimram' hard to analyse as there has been so little raw material on which to work until well into the Saxon era, by which time multiple forms of the name appear in records. Eilert Ekwall believes

In Caesar's usage, Belgium is a geographical subregion comprising the Bellovaci , Ambiani , Atrebates , and Veromandui . These four communities are widely thought to have been the original Belgae in Gaul. Julius Caesar describes Gaul at the time of his conquests (58–51 BC) as divided into three parts, inhabited by

Fintan O'Toole suggested the Keshcarrigan Bowl

In 2001, in a neighbouring valley to the west a village was flooded. The Valley is the furthest east of all the Chiltern Hills valleys. The name of the Mimram is one of the few toponyms recorded within its local area prior to the compilation of

The most important of these tribes in relation to Caesar's campaigns were the Eburones . The other way he used the term was to refer to those related tribes east of the Rhine, who were not Celtic. So the Germani among the Belgae are called, based on Caesar's account, the Germani cisrhenani , to distinguish them from other Germani living east of

The Mimram is crossed at Digswell by the Digswell or Welwyn Viaduct , carrying the East Coast Main Line as well as commuter services to Peterborough and Cambridge, as it spans the entire width of the Maran Valley. The upper reaches of the Mimram are crossed only occasionally by small road bridge or fords (eg at Welwyn and Codicote Bottom ). Welwyn Village's three bridge are at Singlers Bridge, on

The two Roman legions guarding the baggage train at the rear finally arrived and helped to turn the tide of the battle.

The Atuatuci, who were marching to their aid, turned back on hearing of
567-525: A situation opposing Celtic and Germanic in Belgium, in a territory slightly more to the south than the early medieval Romance -Germanic language border", but van Durme accepts that Germanic did not block "Celticisation coming from the south" so "both phenomena were simultaneous and interfering". The medieval Gesta Treverorum compiled by monks of Trier claims that the Belgae were descendants of Trebeta , an otherwise unattested legendary founder of Trier,

Chalk is slightly soluble in rainwater because rain is naturally slightly acidic . The products of chalk weathering are dissolved in rainwater and are transported in stream flow. Chalk streams transport little suspended material (unlike most rivers), but are considered " mineral -rich" due to

The prefecture of Marne is Châlons-en-Champagne , formerly called Châlons-sur-Marne - with the name "Châlons" being etymologically derived from the name of the local Belgic tribe of the Catalauni . However, the link between the French Catalauni and the British Catuvellauni is not categorically proven: some texts assume they are connected (including, recently, Graham Robb's "The Ancient Paths"), while others infer

882-719: The Atrebates , Caesar's former ally, fled to Britain after participating in Vercingetorix 's rebellion and either joined or established a British branch of his tribe. Based on the development of imagery on coins, by the time of the Roman conquest , some of the tribes of south-eastern Britain likely were ruled by a Belgic nobility and were culturally influenced by them. The later civitas (administrative division) of Roman Britain had towns including Portus Adurni ( Portchester ) and Clausentum ( Southampton ). The civitas capital

Thus,

The precise extent of their conquests is unknown. After the Roman conquest of Great Britain, the civitas of the Belgae was bordered to the north by the British Atrebates , who were also a Belgic tribe, and to the east by the Regni , who were probably linked to

O'Rahilly believed that some had moved further west and he equated them with

The term continued to be used in the region until the present day and is reflected in the name of the modern country of Belgium . The consensus among linguists is that the ethnic name Belgae probably comes from the Proto-Celtic root *belg- or *bolg- meaning "to swell (particularly with anger/battle fury/etc.)", cognate with

It has been remarked that Germanic speakers might have been no closer than the river Elbe in the time of Caesar. However, studies of place names, such as those of Maurits Gysseling , have been argued to show evidence of the pre-Roman presence of early Germanic languages throughout

Surviving inscriptions also indicate that Gaulish was spoken in at least part of Belgic territory.

The chalk streams hold a good number of wild salmonid fish species such as the brown trout ( Salmo trutta ), and grayling ( Thymallus thymallus ). In addition to these there are also considerable numbers of stocked brown trout and stocked rainbow trout ( Oncorhynchus mykiss ).

There have been suggestions of it being named after

Caesar's book Commentarii de Bello Gallico begins: "All Gaul is divided into three parts, one of which the Belgae inhabit, the Aquitani another, those who in their own language are called Celts, in ours Gauls, the third. All these differ from each other in language, customs and laws." However, many modern scholars believe that

The arrival and spread of Aylesford-Swarling pottery across the southeastern corner of Britain has been related to the Belgic invasion since Arthur Evans published his excavation of Aylesford in 1890, which was then thought to show "the demonstrable reality of a Belgic invasion", according to Sir Barry Cunliffe , although more recent studies tend to downplay the role of migration in favour of increasing trade links;
1638-431: The Belgae decided to disband their combined force and return to their own lands. Caesar's informants advised him that whichever tribe Caesar attacked first, the others would come to their defence. They broke camp shortly before midnight. At daybreak, satisfied the retreat was not a trap, Caesar sent cavalry to harass the rear guard, followed by three legions. Many of the Belgae were killed in battle. Caesar next marched into

On the other hand, at least part of the Belgae may also have had significant cultural and historical connections to peoples east of the Rhine, including Germanic peoples , judging from archaeological, placename and textual evidence. It has also been argued based on placename studies that the older language of the area, though apparently Indo-European ,

He writes that the Belgae were conspiring and arming themselves in response to his earlier conquests; to counter this threat, he raised two new legions and ordered his Gallic allies, the Aedui , to invade the territory of the Bellovaci , the largest and fiercest of the Belgae tribes. Wary of the numbers and bravery of the Belgae, Caesar initially avoided a pitched battle, resorting mainly to cavalry skirmishes to probe their strengths and weaknesses. Once he

The sound changes described by " Grimm's law " appear to have affected names with older forms, apparently already in the second century BC.

Apart from the Germani, the report of Caesar seems to indicate that more of the Belgae had some Germanic ethnicity, but this is not necessarily what defines a tribe as Belgic.
