The aim of this study is to investigate the tablecloth behaviour of High Bandama basin for the best management of groundwater. It was based on satellite Landsat TM images and piezometric data acquired during three campaigns (August 2009, April 2010, and M... see more

This study constitutes the second part of a first study devoted to the critical flow in a smooth circular conduit. The first study published on this subject showed that two critical states occur in a circular conduit for a given diameter D and slope S0. T... see more

The functional y(yc;m;S0;e;n) = 0 relationship has been well defined and theoretically established for the triangular-shaped channel, where ycis the critical depth, m is the side slope, S0 is the channel bottom slope, e is the absolute roughness, and n is... see more

Using the rational relationship, established by the authors in a previous study that links the properties of critical flow and normal flows, the present investigation is related to the critical state of the flow in a rectangular-shaped channel. The main o... see more

Rapid and uncontrolled urbanization as well as agricultural activities constitute real threats to groundwater which represents one of the most important natural resources for the supply of drinking water, especially in developing countries. The objective ... see more

The study proposes to establish the relation which governs the Manning’s n roughness coefficient in a trapezoidal-shaped channel. It appears that n depends on the depth of the flow, the bottom width of the channel, the slope of the channel, the absolute r... see more

The village of Monzoungoudo in Benin has an abandoned gushing artesian borehole located near the production well that feeds its mini drinking water distribution network. The problem that arises precisely here is the use of the abandoned artesian drilling ... see more

Mouhoun Loop region is one of the 5 regions having the lowest rates of access to drinking water. Further, the failure rate of Borehole is greater than 30%. This area is underlined by both bedrock and sedimentary rocks. In the area, borehole siting is perf... see more

The methodology used in this paper for modeling the Monzoungoudo reservoir consists of a synthesis of hydrodynamic modelling data. The hydraulic approach to the reservoir was carried out by modelling to arrive at a synthetic description. A characterizatio... see more

This paper examines the artificial recharge of water tables by the releases of dams. Two cases have been taken as an example; they are the Boukourdane and Ghrib dams. After each release at the two dams, the level of the alluvial water table was monitored ... see more
