    Climate Change: Assessment And Monitoring Of Meteorological And Hydrological Drought Of Wadi El Hammam Basin (nw- Algeria).
    (University of Eloued جامعة الوادي, 2016-09-01) Djellouli, F.; Bouanani, A.; Babahamed, K.
    During the last century, Algeria experienced a rainfall deficit was recorded in 1944, then successive drought periods since 1975 to the present day in Northen and Eastern. The most recent has repercussions on water resources and on agriculture. In this paper, we focus on the meteorological and hydrological drought. For describing and monitoring drought severity periods, we used meteorological and hydrological drought indices: Standardized Precipitation Index (SPI), effective Drought Index (EDI) and the standardized Runoff Index (SRI). Data was recording for the period of 30 years at Wadi Louza catchment (NW- Algeria). The best correlation between meteorological drought indices was found for 9-month time step. The results show that severe meteorological identified in March-1983 till the end of August-1984 in Sid Ahmed region and extreme hydrological drought during 1993.

    Contribution Of G.i.s. For The Survey And The Management Of Water Resources In The Basin “benhandjir – Tirkount” (ain Sefra) – Mounts Of Ksour - Saharian Atlas – Algeria
    (University of Eloued جامعة الوادي, 2017-05-01) Rahmani, A.; Bouanani, A.; Kacemi, A.; Baba Hamed, K.
    This work relates to the space numerical data processing, containing information having a relationship with the study and the management of the water resources of the basin of « Benhandjir – Tirkount » (Ain Sefra) characterized by his principal aquifer system of the lower Cretaceous sandstone. The study aims to geographical information system (GIS). The adopted methodology is based on two steps. The first approach practical was to reconstitute the aquifer geometry and study of the hydrodynamic and hydrochemical parameters. Analysis of an important variation of the flow and mineralization helped highlight the leading role hydrogeological fault “Ras Touil-Ain Sefra”. The second approach methodological, elaboration from the thematic analyses the synthetic map will serve as a support to a better approach for the management and to identify the zones that are most favourable to wells for the drinkable water, and the agriculture.

    HYDROGEOLOGICAL CARACTERIZATION AND MODELING OF THE AQUIFER OF OUED IN AMGUEL. (TAMANRASSET, CENTRAL HOGGAR - SOUTH ALGERIA)
    (University of Eloued جامعة الوادي, 2018-01-01) Baba-Hamed, K.; Dribat, A.; Bouanani, A.
    The region of In Amguel takes its water from a single groundwater resource known in the Hoggar by "the inferoflux water table", captured by an underground dams with a capacity of 4 Hm3 realised in 2000. This aquifer is highly exploited for supply drinking water and agriculture which create big deficit of water demand. Also, for better management of this inféroflux, we realized its hydrogeological model by using the computer code ASMWIN, allowing us to better understand the hydrodynamic functioning, refine the distribution of spatial characteristics governing groundwater flow in steady state and transient and conduct simulations of the behavior of the system for different operating scenarios.

    Hydrological Modeling In Semi-arid Region Using Hec-hms Model. Case Study In Ain Sefra Watershed, Ksour Mountains (sw-algeria)
    (University of Eloued جامعة الوادي, 2017-05-01) Derdour, A.; Bouanani, A.; Babahamed, K.
    Ain Sefra is one of the Algerian cities that had been experienced several devastating floods during the past 100 years. The purpose of this study is to simulate rainfall-runoff in the semi-arid region of Ain Sefra watershed through the employing of HEC-HMS model. In this paper, the frequency storm is used for the meteorological model, the SCS curve number is selected to calculate the loss rate and SCS unit hydrograph method have been applied to simulate the runoff rate. After calibration and validation, the simulated peak discharges were very closed with observed values.The Nash-Sutcliffe efficiency coefficient was 0.95 which indicated that the hydrological modeling results are satisfactory and accepted for simulation of rainfall-runoff. The peak discharges obtained for the 10, 50, 100 and 1000 years storms were respectively 425.8m3/s, 750.5m3/s, 904.3m3/s and 1328.3m3/s.
