Study on the Impact of the Evolution of Lamaxigou Watershed Geomorphology on Project

Abstract:

The evolution of watershed geomorphology is a natural historical process, which evolves gradually from a low grade balance system to an advanced balance system. In order to preventing and reducing geological hazards in Lamaxigou watershed, this paper introduce present situation of researches on watershed geomorphic evolution at home and abroad, combining with the background of geo-environmental conditions of Lamaxigou watershed. It analyzed the rainfall runoff factors, geological physiognomy factors (lithology, structure and physiognomy, etc.), conditions of the physiognomy (gradient, slope length, slope shape, gully vertical slope, drainage area, the gully density, modulus of soil erosion, vegetation, etc.). In order to finding out the controlling factors for fathering erosion evolvement of this watershed system for providing a scientific basis. Then, it thoroughly discussed the watershed erosion system, analyzing the watershed erosion evolution of different types and characteristics of the formation, and finally studying on the impact of the evolution of Lamaxigou watershed geomorphology on project by altitude integral method, information entropy method and erosion integral method. It can provide a scientific basis for engineering design, construction and operation.
