Abstract:
Every hydrologic design is different because the factors that affect the design vary with location. Thus, it is necessary to make measurements at the design site. Factors such as the following may be important: the size, the slope and the land use of the watershed as well as the water storage and vegetation within the channel. However, the morphometric analysis of the catchment will provide an information on runoff process in the basin.
Though there is a considerable corpus of scientific literature on both theoretical as well as applied geomorphology, one must admit that the experience and the knowledge gained through decades of research, field observations and the laboratory experiments have not found their appropriate application in the areas of resource and environmental management, particularly those involving land and water as their vital components. During the past four decades, the advances made in geomorphology have furthered our understanding of channel properties, its geometry and hydrology. The deserts are much better understood today and so are the coastal areas. Coastal areas are very sensitive in nature and prone to various hydrological problems viz. cyclone, floods, saline water ingress and water logging iesulting from impeded drainage or excessive irrigation.
