Also, bedding and jointing within strata comprising palaeochannels typically result in hazardous conditions related to unstable highwalls in opencast mines and collapsable roof rock in coal adits . Coarse-grained (sandy) palaeochannels and palaeovalleys have been proposed as reservoirs or conduits for
216-454: A palaeochannel and its enclosing sedimentary deposits may consist of unconsolidated, semi-consolidated, or well-cemented sedimentary strata depending on the action of tectonics and diagenesis during their geologic history after deposition. The abandonment of an active fluvial channel and the resulting formation of a palaeochannel can be the result of tectonic processes, geomorphologic processes, anthropogenic activities, climatic changes, or
270-454: A river or stream channel which no longer conveys fluvial discharge as part of an active fluvial system. The term palaeochannel is derived from the combination of two words, palaeo or old , and channel ; i.e., a palaeochannel is an old channel. Palaeochannels may be preserved either as abandoned surface channels on the surface of river floodplains and terraces or infilled and partially or fully buried by younger sediments . The fill of

While it was previously thought that this relict channel was active at the same time as another relict of the Mississippi River 's meander belt, it has been shown that this channel of the Arkansas was inactive approximately 400 years before the Mississippi channel was active. The Arkansas has three distinct sections in its long path through central North America. At its headwaters beginning near Leadville , Colorado ,
432-773: A specific avulsion may be either external or internal to a river system and quite varied. Factors external to a river system that might cause an avulsion include fault activity, sea-level rise, or an increase in flood peak discharge. Factors internal to a river system that might cause an avulsion include sediment influx, breakout along animal pathways, and blockage by ice jams, plant growth, log jams, and beaver dams. A variety of techniques have been used to recognize and map palaeochannels. At first, surficial data from aerial photography, soils maps, topographic maps, archaeological surveys and excavations, and field observations were integrated with subsurface data from geological and engineering borings and cores to recognize and map palaeochannels. As
486-413: A variable and interrelated combination of these factors. The avulsion of an active river or stream is the most common fluvial process resulting in the formation of palaeochannels. It is the process by which flow diverts out of an established river channel into a new permanent course on the adjacent floodplain. An avulsion can be either a full avulsion, in which all of the discharge is transferred out of

The river's source basin lies in Colorado, specifically the Arkansas River Valley. The headwaters derive from the snowpack in the Sawatch and Mosquito mountain ranges. It flows east into Kansas and finally through Oklahoma and Arkansas, where it meets
594-462: Is an avulsion in which an existing active channel is appropriated or if an existing abandoned channel is reoccupied. Second, an avulsion by incision is an avulsion in which a new channel is created by the scouring into the floodplain surface as a direct result of the avulsion. Finally, an avulsion by progradation is an avulsion that results in the formation of an extensive deposition and multi-channeled distributive network. Of these types of avulsions only

Its origin is in the Rocky Mountains in Lake County, Colorado , near Leadville . In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, but
1458-656: The Union Army abandoned its forts in the Indian Territory, including Fort Gibson and Fort Smith, to maximize its strength for campaigns elsewhere. The Confederate Army sent troops from Texas to support its Native American allies. Union troops returned to the area later in the war, after defeating the Confederates at the Battle of Pea Ridge and the Battle of Fort Smith . They began recovering the position it had previously abandoned, most notably Fort Gibson and reopened
1512-692: The United States annexed Texas after the Mexican–American War , in 1846. The treaty was made shortly after the "Old Settler" Cherokee were pushed out of Texas and moved near what became known as Webbers Falls on the Arkansas River. They planned to reunite with the Cherokee who had moved there on the Trail of Tears in 1839. That area, then part of Arkansas Territory , would become Indian Territory and later Oklahoma . This area had long been
1566-1035: The approximate past hydrologic regime of a palaeochannel and the palaeoclimate associated with it. Such empirical equations also allow the estimation of palaeochannel gradient, meander wavelength, sinuosity, and discharge from a palaeochannel exposed in cross-section in an outcrop. The sediments or sedimentary rocks filling palaeochannels also often contain dateable material, micro- and megafossils, and palaeoenvironmental proxies. Fine-grained palaeochannel fills containing autochthonous vertebrate fossils may, in extremely favourable ccircumstances, contain unabraded, complete skeletons that are important for understanding habitat-specific palaeofaunas and associated palaeoenvironments. Fine-grained palaeochannel fills also frequently contain wood, leaves, and palynomorphs that can be used for geologic dating and understanding palaeoclimatic and other palaeoenvironmental conditions, including past rainfall, temperatures and climates, and prehistoric and historic climate change and global warming . Finally,
1620-494: The areas around the Great Lakes began exploring the Mississippi and some of its northern tributaries. They soon learned that the birchbark canoes, which had served them so well on the northern waterways, were too light for use on southern rivers such as the Arkansas. They turned to making and using dugout canoes, which they called pirogues , made by hollowing out the trunks of cottonwood trees. Cottonwoods are plentiful along
1674-603: The avulsion by incision results in the complete abandonment and preservation of a fluvial channel as a palaeochannel. The exact environmental conditions that favour incisional avulsions remain unsettled. However, it is generally agreed that they are promoted by a) rapid aggradation of the main channel and floodplain; b) wide unobstructed floodplain and down-valley drainage; and c) frequently recurring floods of high magnitude. In many floodplains, these conditions and frequent avulsions are correlated with superelevated alluvial ridges and river stages. The event or factor that can trigger

When the McClellan–Kerr Arkansas River Navigation System was constructed between 1963 and 1970, the Arkansas Post Canal was significantly improved, while the lower Arkansas River continued to be bypassed by commercial vessels. Many nations of Native Americans lived near, or along, the 1,450-mile (2,334-km) stretch of
2052-584: The parent channel to a new one, or partial avulsion, in which only a portion of the discharge is transferred to a new one. Only the full avulsion results the formation of a palaeochannel. Partial avulsions result in the formation of anastomosing channels when the divided active channels rejoin downstream and distributary channels when the divided active channels do not rejoin downstream. At least three broadly different types of avulsions, (a) avulsion by annexation; (b) avulsion by incision; and (c) avulsion by progradation, are recognized. First, an avulsion by annexation
2106-502: The preferential underground flow of fresh water. When they extend offshore beneath the continental shelf, they may either transfer freshwater offshore beneath the shelf, or act as pathways for saltwater intrusion into onshore aquifers. Smaller palaeochannels and palaeovalleys, which are commonly filled with muddy or clayey sediments can act as aquicludes that retard and act as barriers to the movement of groundwater. Palaeochannels are often confused with palaeovalleys (or paleovalleys ) in
2160-405: The published literature and studies of groundwater and mineral resources. The nomenclature of palaeochannels must reflect their actual physical character, origin, and evolution if their relationship to mineral and groundwater resources is to be properly understood. Thus, it has been recommended that palaeochannel be used for an inactive channel formed by a river; palaeochannel deposits for

Also, they actually occur in palaeovalleys, which have been mislabeled as palaeochannels . Typically, when palaeochannels formed, they often partially or totally removed any underlying peat , the precursor to coal. Thus, where present, they are directly associated with areas of thin or missing coal called either wash-outs or coal wants . Wash-outs are
2484-457: The sediments or sedimentary rocks filling palaeochannels often contain dateable material, fossils, and palaeoenvironmental proxies. The data derived from the analysis of their morphology and the fossils and palaeoenvironmental proxies can be used to study changes in regional palaeohydrology, palaeoclimates, and palaeoenvironments over geological and historic time scales. The morphology and distribution of palaeochannels can also be used to reconstruct
2538-408: The sediments that infill a palaeochannel; and palaeovalley for a valley incised by an ancient river. This distinction is important, first because not all valleys and palaeovalleys are fluvial in origin; some of them may be either of glacial or tectonic origin. Other palaeovalleys are buried submarine canyons cut by turbidity currents and mass wasting . Second, even the deposits that fill
