Groundwater recharge in arid area, where annual precipitation is much less than potential evaporation, is very important both for science and regional groundwater development. In order to investigate mechanism of rainfall infiltrating into groundwater, four steps in this project were taken from February 15, to March 4,1996 at the United Arab Emirates.(a) Rainfall infiltration processed by artificial rainfall experiments : it was found that sand dune is natural dam for groundwater recharge since its high hydraulic conductivity and high water storage ability.(b) Historical floods rebuilt by flood sedimentation survey : there are 'live' wadis which contribute groundwater recharge and 'die' ones which have been buried in sand dunes and have nothing to do with groundwater recharge.(c) Hydrogeological structure by field survey and remote sensing technology.(d) Estimation of regional groundwater by isotopes and chemical compositions : more than 200 groundwater samples have been taken around the whole U.A.E.It was found that water quality evolution processes respond to regional groundwater movement very well. Groundwater resident time is shorter in 'live' wadis than other areas.

干旱区年降水量远小于潜在蒸发量，其地下水补给对科学研究和区域地下水开发都具有重要意义。为了研究降雨入渗地下水的机理，本项目于1996年2月15日至3月4日在阿拉伯联合酋长国分四个阶段进行。(a)通过人工降雨入渗试验，发现沙丘具有较高的导水率和蓄水能力，是地下水补给的天然屏障。(b)通过洪水沉积调查重建的历史洪水：有“活”的干谷，它们有助于地下水的补给，也有“死”的干谷，它们被埋在沙丘中，与地下水补给无关。(c)水文地质结构野外调查和遥感技术。(d)通过同位素和化学成分估计区域地下水：在整个阿联酋采集了200多个地下水样品，发现水质演变过程对区域地下水运动有很好的响应。地下水驻留时间短，在'活' wadis比其他地区。
