CONTRIBUTION TO THE EXPERIMENTAL STUDY OF THE HYDRAULIC JUMP IN TRAPEZOIDAL CHANNEL WITH POSITIVE SLOPE
(University of Eloued جامعة الوادي, 2018-01-01) Ghomri, A.; Riguet, F.; Khechana, S.
The purpose of this study is to study experimentally the hydraulic jump evolving in a symmetric trapezoidal channel with a positive slope, requires the use of an experimental protocol, and to find experimental relations linking the characteristics of the formed projection. The experimental study investigated the variation of the relative height S = s / h1 of the threshold as a function of the Froude F1 number of the incident flow, for five distinct values of the slope of the channel.
CONTRIBUTION TO THE STUDY OF THE QUALITY PHYSICOCHEMICAL OF THE WATERS OF THE WATER OF THE COMPLEX TERMINAL IN THE VALLEY OF OUED SOUF (SOUTH-EAST ALGERIAN)
(University of Eloued جامعة الوادي, 2017-09-01) Zaiz, I.; Zine, B.; Boutoutaou, D.; Khechana, S.
The area of Oued-Souf consists of a good amount of underground water resources. These resources consist of two big aquifers: the Terminal Complex and the Continental Intercalary. The Chemical quality of these waters creates big problems like: the high mineralization and the concentration of some elements that surpass the recommended norms stated by the OMS. The objectives of the present study relate to quality of the waters within this area and their effects on the environment. According to the results obtained from the different methods utilized, diagram and statistical tool, it could be said that the mineralization of these waters is geologic in origin. The mineralization relate to the composition of the strata that make the two layers. The problem of the Oued-Souf area waters is in essence a problem of quality, for this we believe there must be some rigorous research to develop the chemical quality of these waters and to guarantee their accountability to the international norms before mobilizing them to the consumers.
Integrated Management Of Water Resources In The Valley Of Oued-souf (algeria): Issues Fitness For A New Strategy
(University of Eloued جامعة الوادي, 2010-07-01) Khechana, S.; Derradji, F.; Derouiche, A.
This study designed to analyze and evaluate the results of trend scenarios of the strategy management of water resources used in the valley of Oued-Souf, who led the region to a truly dramatic situation and almost desperate: rise of groundwater and its adverse consequences. In terms of this work, we seek a model (plan) for the development of these resources according to criteria of sustainability, and will take into account socio-economic and ecosystem aspect. That by adaptation and implementation of integrated management of water resources (IMWR) in this unit of water resources, to meet the needs of decision support in water management, so as to guide and mobilize progressive human resources, information, financial and material, as well as various private and public sectors towards finding concrete and measurable results of water and ecosystems.
