Abstract

The work deals with choosing, calibrating and verifying a two-dimensional model for predicting hydraulic and water quality parameters in a section of the Jordan River. The investigated river section was from the "Pkak” bridge in the north to "Mezad Ateret" in the south (4 km long). The model included the following existing programs: HEC-RAS for hydraulic analyses, and CE-QUAL-W2 for both hydraulic and water quality analyses. The model was used to simulate an outside pollution event entering the investigated river. Characterization of the potential causes of polluting events, and possible consequences on Lake Kineret, were carried out on sub-basins of the contributing basin. The chosen event was abrupt release of fish pond water.
The basic input to the model included topographical measurements and measurements of water levels and flow rates taken on the 7th of May, 1999.
The quality parameters included concentrations of dissolved oxygen, biological oxygen demand (BOD), nitrate, ammonia nitrogen, phosphate and volatile and inorganic suspended solids. It was found that for such an event with very high initial concentrations, the first order kinetic equations of the CE-QUAL-W2 should be replaced by zero order equations. Description of a river basin and prediction of water quality at the outlets of tributaries flowing into the river can be done with Geographical information systems (GIS). The model proposed here can be used for detailed analyses in sections of the river for better management.
