干旱区生态环境知识资源中心

In arid ecosystem water supplies, fertile soils, vegetation and wildlife tend to be scarce. Even, existing resources are easily damaged by changes in precipitation pattern, flood phenomena, erosion and human action.

It is universally known that these problems are complex, and requires a solid understanding of landscape-level ecosystem processes, in particular the interaction of geomorphological, hydrological, biological and others natural processes.

An integrated hydrologic modeling/watershed assessment tool is developed to help in determining the sensitivity of semiarid and and landscape to natural phenomena as rainfall events in both time and space. Foum Tillicht a wide and watershed, situated in south-east of Morocco chosen for hydrological modeling.

The present study has been targeted towards preparing inputs to the application of a distributed, event-oriented hydrological model, Kineros, to a subwatershed from the study area. Kineros model, simulates the behavior of and subwatershed by carrying out water balance for each plane element and then routes the resulting runoff at the outlet of the subwatershed. Inputs data used in Kineros, the hydrological model was derived from Digital Elevation Model (DEM) for geometric and topographic data, experimental setup for Manning resistance and remotely sensed data for land use/land cover data derivation.
