Résumé: Integrated management of water resources is a systematic process for the sustainable development, allocation and monitoring of the use of water resources in the context of social, economic and environmental objectives. 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 region2016-06-27T00:00:00ZL’ETUDE DES CARACTERISTIQUES HYDRODYNAMIQUES ET LA VULNERABILITE DE LA PLAINE ALLUVIONNAIRE DE KSAR BELEZMA (BATNA - NORD-EST ALGERIEN)MANSOURI Z.MENANI M.Rhttp://archives.univ-biskra.dz/handle/123456789/77822019-05-06T12:05:20Z2016-06-27T00:00:00ZTitre: L’ETUDE DES CARACTERISTIQUES HYDRODYNAMIQUES ET LA VULNERABILITE DE LA PLAINE ALLUVIONNAIRE DE KSAR BELEZMA (BATNA - NORD-EST ALGERIEN)

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.

Résumé: The ocean surface must be surveyed in order to determine the dynamic
topography, tides, time-variations etc…
The Mean Ocean Dynamic Topography (MDT), which is the distance between
the Geoid and the Mean Sea Surface Height (MSS) and which reflects the ocean
dynamics, is a primary oceanography unknown.
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).2016-06-27T00:00:00ZPROBLEMATIQUE D’AMENAGEMENT ET CONFLIT D’USAGE DE L’EAU EN ZONE DE MONTAGNE, CAS DES MONTS DE BENI CHOUGRANE (NORD-OUEST ALGERIEN)ZERKAOUI LBENSLIMANE MHAMIMED AKHALDI Ahttp://archives.univ-biskra.dz/handle/123456789/77802019-05-06T12:04:04Z2016-06-27T00:00:00ZTitre: PROBLEMATIQUE D’AMENAGEMENT ET CONFLIT D’USAGE DE L’EAU EN ZONE DE MONTAGNE, CAS DES MONTS DE BENI CHOUGRANE (NORD-OUEST ALGERIEN)

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
