The understanding of water resources for the purpose of ground and surface water management as two inseparable systems is great importance. In this study by examining the time series of climatic variables (precipitation), hydrological (flow and consume) and the level of water table, the parameters associated with each other and with fluctuating water table can be realized. There was a Direct relation between precipitation and flow with the ground water level, on the other hand the consume and ground water level were inversely related with each other. Then, by examining the cross correlation diagram of rainfall vs. water table level, reaction delays were identified. The results indicate water table level were related to rainfall with one month lag, whereas for flow, related on time; but for consume indicated two month lag in the plain Ajabshir. Finally, regression analysis of variables with the level of the water table was obtained.
Keywords: precipitation, flow, water table level, cross correlation.
