Conteúdo: 	This report describes the results of an irrigation performance evaluation using remote sensing techniques, GIS procedures, and hydrologic modeling at a regional scale. The study area was the Sirsa Irrigation Circle, which serves a gross area of 483,000 hectares within the Bhakra Irrigation System in northwest India. Satellite remote sensing information shows uniformity in wheat yields across the area but nonumiformity in irrigated wheat intensity. This nonuniformity is evidence that warabandi-the principle of allocating the right to irrigate in proportion to landholdings-is not delivering water in proportion to land area. Modeling revealed areas with differing hydeologic characteristics in the Sirsa ciecle. Correlation analysis between wheat yield and hydrologic terms indicated that variations in wheat yield are explained more by hydrologic fectors such as tubewell use and underground water movement than by canal flows.
