AbstractThis thesis pertains to the ground water resources of the E1 Asentamiento Campesino E1 Cortijo area, which is located within the mountain ranges of north-central Venezuela, South America. The area described in this thesis is an agricultural area of 400 hectares (1,000 acres) lying in a basin of 2,100 hectares (5,187 acres). The sediments underlying the area consist of about 100 meters (328 feet) of gravel, sand and clay of Quaternary age and are bounded on the north and south by relatively impermeable metamorphic rocks. The purpose of the investigation was to determine and to describe the ground water conditions in the mentioned area with special emphasis on the development of the ground water resources. The sources and movement of ground water, the recharge and discharge relations and the effects of pumping on the water levels are described. Ground water occurs under water table conditions and precipitation and unqerf10w represent the sources of recharge to the aquifer. The coefficients of transmissibility and storage were estimated to be 1,800 cubic meters per day (154,700 g./d./ft.), and 0.11 respectively. Water quality is satisfactory for irrigation use, but concentrations of turbidity, apparent color and dissolved-iron exceed the amount recommended by the United States Public Health Service for drinking purposes.
