Amjadi A. Hydrogeochemical particular of groundwater's Khorramabad and Shiraz basins (Western of Iran)

A research object is the ground aquifer's horizons of Khorramabad Shiraz basins of Western Iran. A purpose of work is a study of gidrogeodinamic and gidrogeokhemical features of the ground aquifer's horizons of Khorramabad Shiraz basins both in environmental conditions and during their exploitation. In the thesis investigated laws of formation drinking water in the aquifer's Khorramabad Shiraz basins depressions in natural conditions and on there's exploitation. For example of this horizon established laws of formation of groundwater. The basic kinds of research are: hydrogeochemical investigations, multivariate statistical, modeling on the IBM PC Pentium. Calculated balances of groundwater Khorramabad and Shiraz basins and conducted their comparison. Established that the balance of the supplies in these basins exceeding profitable parts. The deficit of groundwater in the Shiraz basin include -0.61(L / s) in the 1 km^2, and in the Khorramabad basin -0.59(L/s) in the 1 km^2. It is proved that the groundwater's level in the Khorramabad basin every year will decline to 0.76 m. In the Khorramabad and Shiraz basins data determined by hydrogeochemical similarity of chemical compositions of groundwater and detected plot groundwater aquifer with similar chemical composition by the method which is based on used by of the cluster analysis. For hydrogeochemical Data substantiated the similarity conditions supplies and contamination of groundwater's aquifer these basins by the method based on the used by of factor analysis of chemical composition. For the forecast chemical composition of groundwater is proposed stochastic model hydrogeochemical process.
