NEW APPROACH TO ESTIMATE GROUNDWATER RECHARGE IN SEMIARID AREA: CASE STUDY OF DJELFA

Abstract

Groundwater recharge (GWR) is the most solicited resources to satisfy the different needs it used to supply population daily needs in water, and for Agricultural and industrial activities. Estimation of this GWR is very necessary to an actionable management plane of water resources; serval factors are control Groundwater recharge phenomena (B. R. Scanlon et al, 2006); Geological and soil characteristics of the study Area, Slope and topographical parameters of the area, Hydro climatic conditions (Precipitation, Surface runoff and Evapotranspiration) In this paper; a new model was proposed for groundwater assessment in semi-arid area. This model is based on three parameters (temperature, precipitation, and geological factor); this model was tested in semi-arid area in the region of Djelfa (Algeria).
