The Survey of Drought Effects on Hamadan PlanesUnder Ground Water Resources Using MultivariateStatatistics and GIS Analysis

Water Resources management require knowledge, applied methods and suitable policyin wet and drought periods.Climatic and Hydrological variables of running waters as independent variablehave been considered for determining Relationship with planes water table (dependentvariable) in Hamadan planes water ground Resources for drought effect in monthlyscale during 1983-1999 years. The study method has been concentrated on multipleregression because of representing suitable result. As a result climatic and hydrologicabnormal effects show 42 percent water table deficits planes relationship betweenclimatic independents variables with decreasing severity. It was used GIS spatialability analytical for water table critical deficits assessment. It has been regionalizedthe water table deficits intensity planes, hence Bahar plane has the most deficitsintensity but the surrounding planes contact with heights have the most less amount.
