Determination of irrigation regimes based on geospatial technologies in water scarcity areas

In the case of increasing water scarcity, determining demand irrigated land is an important process. The for lands and crops in Republic Uzbekistan realized through nine hydromodular zones, which were developed regarding Bespolov’s methodology 1980s. However, order to determine regime each crop field, it necessary create electronic zoning maps based on GIS technologies. This study uses technology fields Bukhara region while considering mechanical properties soils groundwater levels. Soil composition agricultural land’s geodatabase was created mapped with three categories soils: light, medium heavy. Annually obtained data from observation wells analysed distribution level by Inverse Distance Weighting (IDW) interpolation method referenced detected coordinate values. raster calculator function ArcGIS used identify hydro module zones definite criteria soil level. As a result, first time form.
