Hydrology of the Jordan River Basin: A GIS-Based System to Better Guide Water Resources Management and Decision Making

A new method of participatory decision support that can be used in transboundary basins is presented. The framework of this method relies first on the creation of a transboundary geographic information system database to store hydrologic data and allow easy access to data from stakeholders. A participatory hydro-political framework is developed to help set up hydrologic models and evaluate joint water management scenarios. Results show that the countries of the Jordan River could benefit from the framework and in the case of southern Lebanon, six climate stations should be replaced or reactivated. Finally, the mechanism of a Lebanese Hydrologic Information System is presented and shows that an observation data model will facilitate science and policy integration.
