It differs from the sectoral approach that applies in many countries. When the responsibility of drinking water based on an agency for water to another for irrigation and yet another for the environment, the lack of inter-sectoral linkages leads management and development uncoordinated resources water, resulting in conflict and waste. Djemila ancient city named by the Romans which they have developed a system of management of water resources based on the distribution in the three sectors of the time the agriculture , baths and drinking water for the population and army. Water resources exploited and capture sources Cenomanian limestone, the limestone-marl and limestone of Maastrichtian and Ypresian in the heart of the anticline of the web Djemila. The same sources have been exploited since Roman times to the present time, but the managements techniques differ from one time to another, or finds an anarchic exploitation strategies without making the resource Insufficient water for agriculture, drinking and units of building materials (brick). Perspective as integrated water resources management (IWRM) proposes a planning process to meet the future needs of the water resources in the region 2016-06-27T00:00:00Z http://archives.univ-biskra.dz/handle/123456789/7782 Titre: L’ETUDE DES CARACTERISTIQUES HYDRODYNAMIQUES ET LA VULNERABILITE DE LA PLAINE ALLUVIONNAIRE DE KSAR BELEZMA (BATNA - NORD-EST ALGERIEN) Auteur(s): MANSOURI Z.; MENANI M.R Résumé: The cartography of the vulnerability in the pollution of subterranean waters allows identifying zones with high risk of contamination who takes into account the major part of the hydrogeological factors which allocate and control the flow of subterranean waters: the depth of the water, the refill. These factors are represented by weights and quotations which depend respectively on their relative importance and on local hydrogeological conditions. The overall of the weights and the quotations of the diverse parameters and in a numerical value which is the indication Drastic.

The processing of 21 years altimetry satellite measurements by the correction of the environmental, geophysical and orbital effects, permit us to determinate the mean sea surface height with 1 cm of precision, while using a Geoid model based on 03 years of GOCE satellite measurements, we can calculate the Mean Dynamic Topography over the Western Mediterranean sea. The variation of the obtained surface is between -0.75 and 0.75m. The obtained surface is compared with RioMed which the Mean dynamic topography over the Mediterranean Sea provided by AVISO Altimetry (CNES). 2016-06-27T00:00:00Z http://archives.univ-biskra.dz/handle/123456789/7780 Titre: PROBLEMATIQUE D’AMENAGEMENT ET CONFLIT D’USAGE DE L’EAU EN ZONE DE MONTAGNE, CAS DES MONTS DE BENI CHOUGRANE (NORD-OUEST ALGERIEN) Auteur(s): ZERKAOUI L; BENSLIMANE M; HAMIMED A; KHALDI A Résumé: The water management in mountain areas is a major concern in Algeria; due to the twin problems it poses, namely, siltation of dams and the degradation of soil fertility. To this end, a new form of organization of water management at the watershed scale, in this case the 'associations of common interest (ACI)', established by the waters code. The purpose of this paper is to evaluate this new experience of water management at the watershed level, setting up for a decade to identify the constraints related to the mode of management water resources. The successful experimental site was covered mountains of Beni-Chougrane (Mascara) because of the fragility of its water resources and soil and the importance of investments in terms of SMH (small and medium hydraulic). The methodology adopted in this work is based refers to a sample of nine (9) small dams, whose management is entrusted to private farmers, supposed to be organized in ACI. The results of these investigations show that this form of organization remains far short of the objectives expected by the government, which leads to degradation of hydro-systems, see conflicts of multi-use consequences. 2016-06-27T00:00:00Z
