IMPROVING METHODS FOR MAPPING IRRIGATION NETWORKS USING GIS TECHNOLOGIES.

<em>In this paper, the evolution of geographic information systems (GIS) has facilitated the use of irrigation network data based on topography. The use of spatial data for irrigation has emerged from the great capacity of GIS tools to store and manage information on the hydromorphology of the basin. These models use spatially variable topography data to convert precipitation to surface water flow. Manual manipulation of maps has always been a challenge in the analysis and design of large-scale water resources projects. Water runs off the hillside - this clears up the importance of terrain modeling in watershed management. Thus, the integration of the hydrological model into the GIS environment has aroused the great interest of scientists and engineers. The paper describes attempts by researchers to integrate GIS and hydraulic modeling for watershed analysis.</em>
