The Effects of Climatic Oscillation and water consumption on Groundwater Level Variations in Damene Plain

Abstract

Groundwateris oneof the most importantsourcesoffresh waterneededinthe world. Inthis study,climate data of precipitation, temperature and evaporation in sevenmeteorologicalstation;were been used at 20-yearperiod(90-1370). The researchmethodis acausalmanner. Thecorrelation and regressionstatistical methodswere used to studyvariation of precipitation onaquiferwater levels. Average of totalrainfallmonthly ofcatchmentwas calculated using of data from the1430cell of 240maps(20 yearsx 12months), respectively. Review of iso-drop maps show that undergroundwater levelhas dropped in someareas up to44meters. On the other hand, with respect tomaps ofgroundwatermovement, this resultcanbeapplied a firmmanagement on removalofgroundwater. Because the wateris movingaround theaquifertoitscenter due to lawrelated dishes. Soyouincrease theharvestbypalmCentral Plainswells, wellssharplyagainstaplainedgeand causingthemtoshrivel. Our studyshowed aquite directrelationship between precipitation with water levelbutrelationship of temperature andevaporation with waterbalance is reversed. Therefore theprocess of consumption mustbe formulatedin such a waythat the amount ofwaterfedbyrainfallcouldbeaccountable forthedischarge.
