Abstract

The GARDENIA model is one of the strategies that could play a constructive role in improving the performance of the rainfall- runoff conceptual models. The main objective of this article is to identify and characterize the hydrological behavior of the wadi Louza watershed. The model simulates the main mechanisms of the water cycle in a watershed through simplified physical laws. These correspond to a flow through a succession of tanks. Data from 1987 / 1988-2007 / 2008 are used with some wet and other dry periods. The results show that in the calibration phase the model has a robustness to produce reliable simulation of flows in the monthly time step. Its application over different periods (dry and wet) has shown a certain efficiency for all periods. During the validation phase, the model was able to generate the series of flows for most periods. In terms of hydrological balance, the model was able to quantify the different components (real evapotranspiration, runoff, infiltration, recharge) and to separate the different components of the flow. The assessment of recharge during the dry period and the wet period, has shown us the effects of climate variability on water resources.
