This data integration is for the selection of artificial recharge methods to solve the water crisis in Shkhothai Groundwater Project, Zone I. The investigation of the economical recharge place, the shallowest sand body at the top of main aquifer, includes several steps. This started from collecting of existing data, satellite and aerial-photograph interpretation, geophysical surveys, and drilling. The result is that the shallowest sand deposited from former Yom River is 6 meters depth. The proposed artificial recharge methods are : 1) lateral recharge from elevated water level in Yom River by the construction of a weir. The weir should be at the downstream side of the connecting point of Yom River and shallowest aquifer of former Yom River, 2) lateral recharge from well-point system at the connecting point of Yom River and shallowest aquifer of former Yom River, 3) surface recharge from Huai Tha Phae irrigation canals, and 4) surface recharge from the infiltration of existing ponds.
