Abstract

The present study has been conducted to find out the spatial and topographical (elevation) variation of rainfall in Kerman province in Iran using GIS. Totally twelve rain gauge stations rainfall data have been used for the study which is from 1381 to 1392 (based on the Persian calendar). The co-efficient of variation has been calculated from the rainfall data and its result has been interpolated using IDW technique to find out the spatial variation. The result of co-efficient of variation depicts that, 2.70 per cent area has been covered by very low variation, 29.14 per cent by low, 41.90 per cent by moderate, 24.70 per cent by high and 1.56 per cent by very high variation. Then the analysis of topographical variation with the rainfall shows the positive relationship, which illustrates higher amount of rainfall in high elevated areas compared to lower height.
