Lower Jordan River Basin, Eastern Mediterranean Water scarcity and data are two of the main challenges for water management in study region, therefore, all possible information should be extracted from existing data. In this context, Budyko framework offers possibilities not yet sufficiently explored evaluating water-energy balance estimating availabilities. study, we applied a parametric type equation to basin compared global products, output hydrological model TRAIN-ZIN as well values literature. The curve shape parameters fitted on different temporal spatial scales were used estimate renewable resources with publicly available three subbasins. adjusted curves illustrate influence non-climatic factors such vegetation or soil storage related relatively low efficiency evapotranspiration, despite high evaporative demand. Renewable estimated 25 30% precipitation average most cases more strongly affected by inter-annual variabilities than variance between derived curves.
