investigate the effect of karst development on karstic springs hydrogeology treatment of kermanshah province

abstract one of the importance groundwater resources in kermanshah province is karstic aquifer. this study aimed to investigate the role of development of karstic aquifer in karst springs hydrological properties have been conducted. the studies areas are two karst aquifers include the bistoon-parau and patagh mountain in kermanshah province. in the bistoon-parau region we used of bistoon, berkeh and gaznahleh springs data and in the patagh region of ghareh bolagh spring data used. in this study, we used monthly precipitation and springs discharge during the 20 years. to determinate the development or undevelopment of karstic aquifer, recession coefficient, storage dynamics volume and catchment area were calculated for each springs. the results of calculation of dynamic storage volume showed that the ghare bolagh springs in patagh region has dynamic storage volume equal 29/3 million cubic meters that more than bistoon, berkeh and gaznahleh springs in bistoon-parau region with dynamic storage volume equal 0/55, 2/2 and 1/3 million cubic meters respectively. so these results showed the bistoon-parau more development of than patagh region. based on the results responses of the hydrological model the bistoon-parav is developed karst aquifer more quickly and severe than is patagh area.
