Talus cones produced by mass moving, north shore of Isfjord, Svalbard, Norway Mass wasting at Palo Duro Canyon, West Texas (2002) A rockfall in Grand Canyon National Park. Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
The width of the river spans from about 1.5 km (0.9 mi) at Makrai to 3 km (1.9 mi) near Bharuch and to an estuary of 21 km (13.0 mi) at the Gulf of Cambay. An old channel of the river, 1 km (0.6 mi) to 2 km (1.2 mi) south from the present one, is very clear below Bharuch.
Their main functions include drainage, filtration, reinforcement, separation, and containment. Geosynthetics are available in a wide range of forms and materials, each to suit a slightly different end-use, although they are frequently used together.
Dynamic rejuvenation may be caused by the epeirogenic uplift of a land mass. Warping or faulting of a drainage basin will steepen the stream gradient followed by the downcutting. The effect of seaward tilting can be felt immediately only when the direction of that stream is parallel to the direction of tilting.
Watersheds, which refer to the regions that separate drainage basins, are able to be defined using small-scale aerial photographs. [5] Landform studies also help identify decreases in surface elevation in natural terrain. and river courses [5] Sketch map showing an example of landform studies in Luk Keng Hill. [1]
