Full textThe basin of the Senegal river has been recently the subject of hydro-agricultural equipment (like the dam of Diama and the dam of Manantali). These equipment have been conceived, in order to promote the irrigate cultures of diversification mainly, especially the rice irrigated culture. However, the functioning of the different hydro-agricultural systems is conditioned by mainly constraints of the social, sanitary, and natural environment, including the climate. Among the climatic constraints we find according to the stations and the seasons: diurnal strong heat and by cold nights, worm and dry winds, and important losses in water because of the evapotranspiration, rainfall, etc. The agroclimatical challenges have been studied, mostly the problems of the choice and settlement of the cycles of the irrigated culture. The frequantial analysis of the data and or the numeric simulation have made it possible to detect on one hand the climatic optimal dates for the cultures and on the other hand the rice varieties which genetic properties are tolerant of not with the atmospheric stresses. The whole results have allowed to distinguish two types of gradients: an e-w gradient which brings differences between littoral stations, semi-continental stations and continental stations then a n-s gradient which opposes the sites of the Sahel and its peripheries

Full textThis study concerns the dissolved and colloidal organic matter in the mixing zones of the Amazon basin. The separation by Sequential Tangential UltraFiltration (STUF) on site indicates an organic matter distribution in the particulate and dissolved domains, respectively, for the black and white waters. It is also shown that the Rio Negro does not produce a simple diluting effect, his waters play a key role in the composition and distribution of organic carbon of the Amazon. The sampling of the Purus River, a Southern tributary of the Rio Solimões, shows a very large concentration (>80% of the TOC concentration) in the dissolved phase. During the mixing of black and white waters, the waters of the Rio Solimões push and go under the Rio Negro ones. An insight into the nature and characterisation of organic matter in tropical river systems is then developed. The exploitation of Excitation and Emission Matrix Fluorescence (EEMF) allows the differentiation of the fluorophores A and C which are observed for all the samples and the fluorophore B which seems to be characteristic of the black waters of the amazonian basin

Full textBarada is a permanent river which drains the water of the Anti Lebanon mountains. It irrigates the city of Damascus and its oasis (ghouta), at the border of the eastern desert. It warranted an harmonious equilibrium of water between the urban functions and the agricultural activities. Today however the demographic burst and the rapid extension of the city towards the ghouta inverse the balance and put many problems: shifting of the ghouta towards the east, big water pollution, water deficiency for human consumption and agriculture, anarchical use and exhaustion of the water sheets in the plain, drying up of the El-Oteibeh lake, salinisation of the soils, advancing of the eastern desert towards the ghouta. The big human concentration all around Damascus (2 million inhabitants = 1/5 of the population living in the country, which represents 1% of the national territory) puts today a serious hydrological problem: the whole of the water resources of the basin is used for human and agricultural necessities, without covering the increasing water needs. The Syrian state has adopted the deep water sheets as potential resources, to fill up the deficiency in human water, on the horizon of the 2010 years. The planning of the water resources in the basin requires today a carefully studied plan, to assure the necessary waters and to restore the hydrological balance in the oasis of the Syrian capital

Full textThe aim of the study is the evolution of alluvial detritism during the holocene in the moyenne durance catchment. Several methods are used : geomorphological and sedimento-stratigraphical analyses : dendrological analyses of subfossil trees well-preserved in holocene deposits; geoarcheological analyses of several sites in alluvial plain ; studies of ancien texts and maps. We observe an aggradation trend since the allerod to the beginning of atlantic. The most important sedimentation rates are during the boreal. Several detritic crisis are detected : at the beginning of younger dryas, at the end of preboreal, during the boreal and at the beginning of atlantic. They succeed with periods of morphological stability corresponding with river forest development (subfossil trees, pinus silvestris). Morphological crisis correspond with climatic crisis. This result accords with other recent paleoclimatical studies. Atlantic correspond with a pedogenic evolution on the slope, a reduction of accumulation rate and incision. This evolution is due to "forest optimum" and regular precipitations. Since atlantic, several crises are detected : during the beginning of subboreal, "la tene", later antiquity, modern times. They are related to climatic degradation and impact of anthropisation. This study point out the importance of climatic changes on the morphological evolution

Full textThis research work on the Agly fluvial system and its drainage basin (1045 km2) has been carried out according to a systemic approach. Various spatiotemporal scales allow to get a long-term view of the evolution and dynamics of this Mediterranean coastal river, since its gradual sinking in a mid-Miocene planation surface. .

Full textAgricultural and water development in the Krishna basin, South India, has led to a progressive over commitment of water resources. Signs of `basin closure' (zero or minimal flow to the ocean) are apparent during dry periods. In 1990-2000, total committed volumes accounted for 90% of the renewable bine water of the basin (and up to 98% if the water needs of the environment are accounted for): there is only little scope for further water resources development and basin-avide water savings. The thesis unpacks the multi-level forces that drove the overbuilding and closure of the Krishna basin and highlights that over-exploitation cornes along changing patterns of access to water. When river basins close, water users are increasingly interconnected and any interventions (supply augmentation, demand management, allocation policies) result in a regional or sectoral redistribution of water, along existing economic, political, and social forces. The trajectory of the Krishna basin is one of progressive alteration of the river regime, downstream environmental degradation, declining security of supply to all existing users, and thus increasingly likely conflicts. The new Krishna Water Disputes Tribunal is an opportunity for effective and adaptive allocation mechanisms but it needs to be made more responsive to the demands of local communities and to internalize local practices for both social and environmentai benefits. The drivers of river basin closure are manifold and unfold at many nested levels: allocating basin water is not enough and interventions must go beyond water and beyond the basin. This requires a shift in the governance structure of natural resources
