The groundwater quality in the Mitidja plain has known an important deterioration during the last decades due to uncontrolled industrial waste discharges, intensive use of chemical fertilizers in agriculture, and an intense exploitation of groundwater resources. In this paper, we are interested in the Eastern part of the Mitidja plain, which covers an area of 495.52 km2. This study area is characterized by its industrial and agricultural vocation, thereby the problem of groundwater pollution. The study will focus on the fluctuation of the groundwater table, and the interpretation of the water quality analysis result made by ANRH (National Water Resources Agency), during the period between 2006 and 2016. The last ones have been geostatistically approached. This allowed us to carry out a GIS-assisted mapping of the nitrate concentrations in the aquifer and to draw up an exhaustive report on the current state of the relationship between the fluctuation of water table and the nitrate co...

Abstract: A quick and accurate determination of flow passing through a river section is fundamental for a large number of engineering applications, such as flood forecasting models and the real time water resources management. Velocity is one of the basic variables of open channel flow and its variation across a section is described by the velocity profile distribution. This aspect has also been investigated through a probabilistic approach based on the entropy concept, which also expresses the mean flow velocity as a linear ...
