Full textShould we speak about water demand or water demands ? what are their contents and how do the development scenarios take place ? how to help the modeller to design and to realize a long-term water demand forecasting model ? the answer could be in a hierarchical water demand (s) simulation model, that would have a regional basis and be subdivided around an equal number of blocs and homogeneous groups of users. It is open and its results are reproductible because of its modular and multi-dimensional structure. Based upon a complete statistical database, the application of the model to the algerian context provides new strategic insights for an integrated water planification. This application is supported by a computer software

Full textA study of international non-maritime water rights. The analysis concerns the genesisis of a new international law which globally abords the question of international non-maritime waters. It is founded on the notion of an international hydrographic basin which is presented as the field of application imposed by nature and scientific knowledge. It disclaims the new norms which alllow the right to question utilisation and protection of the waters. It presents co-operation such as it exists and such as it would be desirable that it should evolve. It envisages the treatment of the differences

Full textThe expert system "Baobab" is developped for decision-making in water-resources planning in Burkina Faso. The dfevelopment of this system requires a transfer of knowledge from man to engine, which can't be realized without special attention to the constructive process and knowledge acquisition method. This realization allowed us to study some of the advantages and disadvantages in using knowledge-based systems to solve problems in geography. Different branches are studied during this research : the geographical branch, with water-resources management and planning problems in the rural sector of Burkina Faso. Computer science, by practice of knowledge-based system technique. The methodological branch, with effective realization of prototype "Baobab". The epistemological branch, by evaluating interest of using knowledge-based system as a new tool for geography

Full textUrbanization with the concentration of activities in cities contributes to the increase in demand for water services. However, the overexploitation of this resource can cause adverse effects on the environment. One of the effects is the subsidence whose essential causes are strongly related to the consequences of an accelerated urbanization process. Since the 1990s, the previous studies using measurements in situ confirmed deformations in the city-center of Ha Noi (the capital of Vietnam). Few studies have yielded a spatial characterization on the extent of the new urban region and especially for recently urbanized areas in the South and West of the city-center according to the Master Plan approved in 2011. The thesis aims to generate a map of the subsidence in this region for providing an usable information to civil protection by the actors involved in the urban planning in order to avoid or to optimize the development in sensitive area by the realization of planning documents, issued from geospatial data analysis structured in a Geographic Information System. The thesis therefore addresses the subsidence by proposing a methodology based on multi-temporal InSAR with the images ALOS acquired from 2007 to 2011 through which a quantification of subsidence on the territory of Ha Noiwas carried out. Thus a strong difference appears between the two banks of the Red River. The North bank of Red river remains much more static while the South bank presents vertical maximum rates of subsidence of 68mm/year. A map of the subsidence rates has been realized to identify the "sensitive" three "sensitive" sites in districts of Hoang Mai, Ha Dong and Hoai Duc. Identified factors that contribute to this phenomenon can be classified depending on geological and hydrological factors, socio-economic factors relating to the water resource, and use, and territorial planning. The interpretation of the results confirmed that the phenomenon is linked to a combination of several factors : the role of the unsaturated geological layers, the decrease of the water supply aquifers by pumping resulting in undermining process, the role of urbanization and the different types of building foundations. The conversion of subsidence velocity to contour lines allows facilitating the integration with different layers of geospatial data in order to provide a decision making tool in the risk management

Full textThe subject of this thesis is not geopolitics or hydropolitics in the middle east. The purpose of this thesis is to learn the water problems in egypt from the point of view of the policies, i in other words we wanted to study the political work of the egyptian government in the managing of water resources. This approach will allow us to understand in the same time the newi forms of water and some global of the system of egypt. | there are several phenomenons that made change the environment of water management in i egypt. These phenomenon are exogenous and endogenous. " | first, we can observe that the governments of the riparian countries, the international organizations and the international law are unable to found good solutions to set up a cooperation in the nile basin. There is only the agreement between egyptian and sudanese governments of i 1959. Second, in the new international order, the liberal model of government is becoming prevailing, i most of governments in the middle east, like egypt, are sollicited to integrate this model in their own country. Third, the theories of sustainable development are determining the new constraints and the new norms of water management. They are establishing three large objectives : democratization,! institutional reforms and rationalization, from the 80s the egyptian government is confronted with two water problems wich may become tragic in the next years : the increase of the demand in water resources and the fact that it cannot found new forms of supply, apart from the river nile. I so it had to adopt new institutions and new rules to manage water resources and to modifie the behaviours of the consumers. The principal effect of this reform is the emergence of a water policy which is the object of this

Full textThe viva i have the honor to attend before you studies the supply and consumption of drinking water in the Wilayas of Rabat-Sale and Casablanca (1982-2002). This thesis is made up of six different parts, which will try to give an answer to the following four questions: - are the water ressources of the observed area sufficient enough to supply drinking water? - is the supply of drinking water reliable? - is the control of the drinking water sector rational? - are the liquid wastes treated before drainage? The water resources in the observed area do not correspond to the needs in drinking water. Indeed this area not only has the population, but is also the most industrialixed of the country. It counts approximately 5 millions inhabitants (1992) and more than half the economic activities of Morocco, this area consequently uses great quantities of drinking water; in 1992, the consumption was of 191 000 000 m3, 80% of which was for domestic and industrial use. The capacity of the whole of the production equipement for drinking water in the observed area is of 1 168 194 m3/j. With this quantity, the drinking water is available in sufficient quantities in all the centres of the area. The control of the drinking water sector is not for behind that of developped countries

Full textLocated in the south of Senegal, the Casamance basin has a significant potential for rice production. Despite climatic constraints, the local people practice paddy cultivation in the valleys. However, the persistence of negative effects has resulted in the awareness of the need to protect the rice-growing areas against the advance of salt and to improve the use of rainfall available. It is in this context that a number of small dams were built in Casamance by various development actors.This dissertation assesses the hydro-agricultural planning policies in Casamance that were implemented during the last five decades. This appraisal is quite bleak: most of the rice production development programmes did fail in lowlands. This Ph.D. proposes a framework for analyzing the overall situation through a multi-dimensional study: a political dimension at the national and regional levels, a socio-cultural dimension based on the “local”, and a technical dimension referring to small dams. The synthesis of these three entry ways enables to propose intervention models better adapted to the local context and realities

Full textThe city of lome that is inhabited by a million of people is seriously suffering from a lack of drinking water supply. The city is provided with drinking water by 27 borings that are located in 3 different sheets (maestrichtien, continental terminal, paleocene). The water produced and supplied by the rnet is far from being enough to meet the need of the city. Some informal alternative systems, such as well, water selling, and storing rainwater are helping to get round the public service insufficiencies. The dualism also exists in cleaning up the city of lome. Not far from some sewers which date back to the colonial era, some individual draining installations have developed. Although they are not sufficient, they are however making progress. The shartage of drinking water supply and the insalubrity of the city are triggering new outbursts of diseases that are linked to water

Full textIn the twentieth century, diseases transmitted through dirty water are the second worldwide leading cause of death, among children. It kills five times more than the HIV. At long-range forecasts, this situation leads to a vicious circle, in which poor people tend to stay poor. Indeed, consequences of the nutritional status and of the lack of access to safe water have repercussions on the present generation and the next ones. Their vulnerability to infectious diseases is exacerbated by inadequate living conditions. It restricts those people’s abilities to take advantage of other social services, as education, and they cannot rise up the social ladder. This paper will focus on the challenges of the access to safe drinking water in the African cities. The urban area should be, by its density, a potential buying market sufficient for patronizing investments and extension of the water network. In fact, improvements in access and making-sensitive projects, do not gather good results, because of the increasing population and the expansion of shantytowns. Those realities, which are an area of vital concern for developing countries, are not taking into account, by the policies, yet. So, we will wonder if the models for safe access to drinking water imitate the occidental vision (access to water directly linked with the ownership of a real estate) or, if there is emergence of models based on social, politic and economic specificities of African cities. In short, this study is about the junction between supply and technical solutions, with demand and the needs of users. After analyzing a macroeconomic point of view, a study case of Ouagadougou will be produced.

Full textThe wastewater re-use is a very world wide practice in the areas affected by shortages of water resources. For the majority of the countries of the arid and semi arid regions, water became the principal factor limiting their development. Egypt is one of the Mediterranean countries which is affected by shortages of water good quality resources. The re-use of this water for agricultural production is accompanied with salinization problems, which always develops because of the bad irrigation and drainage practices, especially with the irrigated agriculture in arid regions with high rates of evapotranspiration. The irrigation with wastewater is not only one source of dissolved salts but also of metallic trace elements (MTEs). The principal goal of this work was to study the effect of wastewater re-use with different salinity levels on the behaviour of metallic trace elements (MTEs) such as Zn and Pb in the presence or absence of plants. The combined effects of salinity and MTEs on the growth of rye-grass, and its production of biomass as been studied. Two experimental techniques were used : pot cultures with two different irrigation systems, with and without water excess, and hydroponic cultures to evaluate the effects of various salinity levels on the bioavailability, bioaccumulation, and phytotoxicity of Zn and Pb for the rye-grass. Salinity had a similar toxic effect on the growth of plants even if the sensitivity of plants is higher in hydroponic conditions. The bioavailability of Pb is limited compared with Zn which shows a higher transfer to the plants, with its higher translocation in the shoots and its phytotoxic effects on the growth of plants. However, the bioavailability of Pb is increased when the plant react actively to salinity stress. Thus, the bioavailability of MTEs can vary with the salinity. The bioaccumulation and the translocation of the MTEs in the shoots of the rye-grass increase when the plant reacts actively to a saline stress. The toxic effect of soil and irrigation water salinity on the growth of rye-grass and production of biomass can be affected by the MTEs according to the interaction between these two risk factors

Full textHouseholds access to potable water and electricity distribution networks, in many town and cities in developing countries is still very limited. How can the access of urban households to water and electricity be upgraded and sustained without neither diminishing the quality of services offset nor considerably increasing the financial burden on the state ? Therefore, to provide an appropriate answer, we present the following propositions: On the financial side, a computerised methodology is established to evaluate the affordability of households in order rationalised investment and network exploitation. Technical issues deals with points of reference as an alternative to current design codes. On the basis of compatibility between the affordability of households and points of reference of which the probability of occurrence constitutes the risk, we define for each urban stratum, an appropriate service level, the type and optimal design of the distribution network; Finally, field tests carried out in three Cameroonian towns namely Obala, Yaounde and Bandjoun confirm the model proposed for network development. We have also put into place a graphical financial risk evaluation method which constitutes a decision making aid for a network extension or reinforcement. The procedure proposed goes beyond the customary procedure to obtain the ration of underserved “households per KM” of network is about 40%, this corresponds to an overall investment gain of 57%

Full textThe work carried out within the framework of this thesis entitled "Tool of assistance to the diagnosis of the drinkable water supply network for the town of Chisinau by space and temporal analysis of the hydraulic dysfunctionments" concerns the development of a model of the future tool of assistance to management infrastructures and applied of the drinkable water supply network of the town of Chisinau Moldavie (1200 km of drains - 800 000 inhabitants). This research task deals with two main topics :"Diagnosis": It acts by a successive and recursive analysis (using temporal requests), to detect the simultaneity of two or several observations (demonstrations of dysfunction). The dysfonctionments can occur in the same laps of time and are examined from topological hydraulic relations and being able to exist between the sites where the dysfunctions are observed. The graph theory, and more particularly the Petri net, are used and make possible to pass from an analysis space time between 2 or m events to an analysis integrating causality between 2 events. "Decision-making aid": An "emergency level" is associated to each section of the network in order to ensure the follow-up of the rehabilitation of the infrastructures, The assistance with the rehabilitation with the determination of priority zones, the gestion/maintenance of the network for the perenniality of the network can be achieved. This emergency level is quantified by using a Hierarchical Method Multicriterion developed by SAATY (considering criteria technical, economic, social, environmental as well as the policy of the managers). Developed methodology uses various tools and resulting methods: temporal data bases, space analysis and SIG, cognitive reasoning and hydraulic modeling of the flows, theory of graphs and Petri net. The tool is tested on a pilot sector of Chisinau the city, which represents approximately 7% of the drinkable water supply network in the city. The whole of the network will be taken into account later when the validation of this portion of network will be made by the engineering departments of the town of Chisinau (Moldavie)

Full textThe recent period of dryness in maghreb (1981-1986) attracted the attention on the rarety of water. Indispensable element to life, water is a factor limitating a country's development. So, algiers like many other mediterranean cities, is submitted to physical natural constraints characterized by interseasonal and interannual climatic variations (600 mm annual precipitations) which have consequences upon exploitable resources and, therefore, water distribution of the 2 millions citizens. The algiers's growth increases its water needs and the result is an inadequacy between the supply and demand. The water shortage, in the past arusing out, became structural. The research is divided in 3 parts. The first part (105 p) concerns the mobilization of the water resources and the distribution, the administration of the drinkable water. The absence of local water resources makes algiers a dependant zone for its supplying water of its hinterland and of the border areas. The second part (119 p), by using the available statistics, analyses the water consumption in algiers and the problem of competition for the use of water in the region. The theme of unequal distribution of water in the urban space is also treated, a theme which is more widely analysed in the third part (84 p). The survey of the consumption habits of water is realized from an inquiry upon 93 women living in 3 different parts of algiers (hydra, belfort, casbah). The purpose of this survey is to show how the households absorb water in their daily life, the consequences of water rationing and the fundamental role of women in the daily administration of water

Full textHow to manage the water resource in order to maximise the welfare from a quantitative point of view ? How to allocate water between users and more particulary between irrigators and others users ; in the french socio-economic environment ? These are the questions, we have tried to answer through this phd thesis. The thesis is made of three parts. In part i, the agricultural, environmental and fnancial stakes of a rational water management are described. Technical information useful for the following parts are also given, such as paysant motivations, relation between quantity of water supplied and plant yield, irrigation water costs, and water resource management models. Part ii is exclusively dedicated to the the evaluation of the agricultural water demand function. Two types of methods are described. The first is based on farm production models whixh can be agregated to evaluate the regional demand. The other methods re based on the analysis of economic data which are supposed to reveal the paysant preferences and the value they attribute to water. In the last part, the concept of optimal water management is defined. The potential techniques, which exist to maximise the collectif welfare, are analysed and among them, more attention is given to the marginal cost tarification and the water market. All this work refers more specificaly to the south wxest of france and more precisely to the garonne valey
