Titre: Analyse de la corrélation entre les données in situ et satellitaires pour l'estimation de l'humidité du sol dans la plaine de la Mitidja Auteur(s): Djellai, Mounia Résumé: This thesis explores the analysis of the correlation between in situ and satellite data to estimate soil moisture in the Mitidja plain. Soil moisture is a crucial parameter for agriculture, water resource management, and understanding ecosystems. In this study, in situ measurements of soil moisture were collected and compared with satellite data from various sensors. The main objective was to assess the reliability and accuracy of satellite data for estimating soil moisture at different temporal and spatial scales. Description: Master

Titre: La cartographie des nitrates de la plaine de Mitidja Auteur(s): Mokadem, Tahar Résumé: The aim of this work is to establish the mapping nitratres of the plain of Mitija showing the proportions of nitrate concentrations in the plain by making use of various geological and hydro-geological studies conducted by the National Agency of Water Resources and National Meteorology Institute in the years (2011-2015). Plain Mitija is experiencing a serious crisis in terms of air pollution and contamination of surface and groundwater due to the irrational use of chemical fertilizers in agriculture, and industrial waste, in particular the west side of the Mitija that contains a large proportion of nitrates up to 121.8 mg /l.

Titre: Modélisation du transport solide à l'échelle de la crue en utilisant le logiciel ( HECRAS-HECHMS ) cas d'Oued Abiod Auteur(s): Derghal, Zakarya Résumé: The hydrological study of erosion and sediment transport carried on the watershed of OuedLabiod, for improving the understanding of the phenomenon and its estimate. The watershed of OuedLaboid covers an area of 1,300 km² and almost its totality is located in a semi- arid environment. After determining all parameters geomorphological, geological, hydrological and climatic of sub watershed forming the basin, we passed to the quantitative simulation of liquid flow rates and sediment loads in these sub-basins. Using the data of precipitation stations(Ichmoul ,Tkout et Tefefele,) whichguaranteed given the maximum daily rainfall and hydrometric station ( Mechounche )ensuring the observed flow, to insert in the universal hydrological model was used to calculate the various flood hydrograph for a specific event, and sediment after stalling and validated the model .

Titre: Impact du changement climatique sur la fluctuation piézométrique de la nappe de la Mitidja Auteur(s): Aliouche, Yaaqoub Résumé: The aquifer of Mitidja has known a relative decrease in its piezometer level during the last decade because of the influences of the rapid increase in the population and their needs for water and the effect of climate change. This situation represents a strong constrains for the sensitive groundwater in the plain. The aim of this study is to highlight the existence of climate change, manifested primarily by variability in the amount of rainfall and irregularities in the plain studied, and highlight its impact on food of groundwater reserves, in the surface water table. To do this, we used various data (rainfall and piezometry) and methods (the Standardized Precipitation Index (SPI), homogeneity test and cumulative rainfall, Statics Buishand, test Pettit, Bayesian method Lee and Heghinian and procedure Hubert segmentation).The results indicate the existence of a break in 2001 manifested by change in rainfall patterns. The symptoms of this climate change effects groundwater resources.
