In and semi-arid regions, surface water resources are scarce and, in most cases, groundwater is the onlynatural resource of freshwater. Pumping of groundwater often exceeds natural recharge. Therefore,groundwater level are declining and its quality is deteriorating. Sustainable management of groundwater is thus a key Issue and requires implementation of appropriate technologies to augment ground water resources. Artificial recharge augments the natural movement of surface water into the underground form' illations using some means of construction whereby surface water from streams or lakes is made to infiltrate into the ground.

The UAE is known by its arid conditions and limited renewable freshwater resources. Surface water in UAE is very limited and of a little significance in the water budget of the country. Despite the construction of many desalination plants, groundwater represents a vital natural resource. Although it may not be Suitable in most cases, for drinking it represents the main source for irrigation. About 85% of the total water consumption in UAE is from groundwater. The sustainability of this precious resource is of prime concern in the UAE. Many dams have been constructed during the last two decades across the main wadis to harvest surface water runoff and recharge groundwater.

The importance of this study evolves from the need to assess surface water and groundwater resources in the main wadis which are of vital role in the sustainable development of UAE, specifically, the agricultural development. The study aims at the simulation and quantitative assessment of surface water runoff and the associated groundwater recharge in Wadi Ham, UAE. HEC-HMS and MODFLOW models were used. Due to data limitation, HEC-HMS was applied for the period 1979 to 1989 and MOD FLOW was applied for the penned form January, 1990 to December, 1993. The study provides a methodology that can be followed into the sites of similar hydrological and hydrogeological conditions. All the data and facilities were provided through a project entitled "Assessment of the effectiveness of AI-Bih, AI-Tawiyaen and Ham Dams in

groundwater recharge using numerical models" . The project was funded by the Ministry of Agriculture an Fisheries .......
