Introduction: A trip was taken from July 3 to July 17, 1985 to Sudan to study the El Obeid compartmented reservoir system. This system supplies most of the domestic water for the city of El Obeid which has a population of 200,000 to 250,000 people. This water supply was exhausted in March of 1985 and the town was out of water until the monsoon rains began July 2, 1985. Approximately one week was spent in El Obeid and Kadugli. The remainder of the time was spent in Khartoum where the IBM PC was used. Some time was also spent in Khartoum in obtaining flattened ceramic spheres for evaporation control.

A mathematical model is proposed to estimate annual recharge rates from various sources into an aquifer, based on chemical and isotopic data. The aquifer is divided into mixing cells. For each mixing cell, annual mass balance equations are written which express the conservation of water, dissolved chemicals, and stable environmental isotopes. These equations are solved simultaneously for unknown recharge rates by quadratic programming. A similar approach was used earlier to estimate inflows into a river reach which acts as a single mixing cell. The sensitivity of the model to input errors is analyzed by applying it to synthetic data corrupted by artificial noise. The ability of the model to deal with real data is illustrated by applying it to the semiarid Aravaipa basin in southern Arizona.
