PROJECT: ESTUDIO HIDROGEOLOGICO CUENCA DEL LAGO DE VALENCIA and other projects in Venezuela
As a consultant to GEOCIN C.A., working under a contract with Ministerio del Ambiente y de los Recursos Naturales Renovables (MARNR), J.Karanjac provided the following services:
- Compiled, analyzed, interpreted, and reported data on climatology, surface water hydrology, hydrogeology, groundwater abstraction, and the like in a report titled: Estudio Hidrogeologico Preliminar Cuenca del Lago de Valencia.
- Made four mathematical models of ground water systems in Maracay, Valencia, San Joaquin, Rio Guigue, all within the watershed of the Valencia Lake; and
- Created Basic Documentation (Documentacion Basica) using computer software, with wells' lithologies, observation wells' records, ground water quality, and hydrogeological parameters.
The project, which terminated in 1983, was an initial step in the sequence of environmental programs leading to the World Bank financed project "Programa de Saneamiento Ambiental Integral de la Cuenca del Lago de Valencia".
The problems identified during the hydrogeological study authored by J.Karanjac are the following:
- depletion of ground water storage due to overpumping, especially near the city of Maracay;
- intrusion of polluted lake water ("aguas negras") into the depleted aquifer along the lake perimeter and deterioration of ground water used by food production, textile, and paper industries;
- possible land subsidence in areas with heavily depleted groundwater resources.
In addition to the Lago de Valencia study, J.Karanjac worked as principal consultant and contributor in the following projects in Venezuela between 1972 and 1991:
- Estudio Hidrogeologico Preliminar con Modelo Matematico, Mesa de Guanipa, Estado Anzoategui, 1973
