What is the Regime channel, its classification- Lacey Regime theory

WebJan 18, 2024 · Alluvial soil: The soil which is formed by the continuous deposition of silt is known as the alluvial soil. The river has to carry a heavy charge of silt in the rainy season. When the river overflows its banks during flooding, the silt particles get deposited on the adjoining areas. This deposition of silt continues year after year. WebIn incoherent alluvium, Lacey’s regime theo dimensions, although there is a marked divergence when applied to large rivers due to omission . of an important parameter, viz., quantity of silt in suspension are important where silt charge in the flow predominates.

WebAlluvium occurs in deposits that compose a variety of different landforms. Recent alluvium occurs on nearly level floodplains adjacent to streams and rivers. Older alluvium occurs on alluvial terraces, which are generally higher than associated floodplains and are not subject to frequent flooding. Higher terraces subject to upland erosion are ... WebLacey assumed the section of a regime channel as made of free incoherent alluvium which is readily scoured when velocity of flow increases even slightly than the regime velocity. But actually canal banks are not so freely erodible. After a run of few months the banks of canal become so rigid that they cannot be scoured even with the twice of ...
