Water Evaluation And Planning

AbstractBechar city is located in arid climate of the Algerian Sahara, with an average annual rainfall of about 72 mm. There are two sources to ensure the water supply of the town of Bechar; the first comes from a watershed made up of eight non-renewable boreholes, and the second comes from the Djorf Torba dam, located about 45 km to the west. The pressure on water demand in the highland region depends on many factors, namely: demographic, social, climatic and economic. This study is based on the application of a water evaluation and planning computer tool on the city of Bechar. Which allows us to analyze the supply–demand balance in the water and assess the impact of different scenarios on the study area for manage the water resource and the projected water demand for the different sectors (drinking water, industrial water and agriculture) until 2060.

Water Evaluation And Planning

Water ecosystem service is the most important element that supports Tafilalet agro-ecosystems. In this region, drought frequency is increasing, which complicate the management groundwater reserves. The ephemeral flows of the rivers force people to use groundwater to meet the population demand. Consequently, water resource management is of significant importance the sustainability of this area. Water evaluation and planning (WEAP) is useful management software used to evaluate and trace the trend of water demand. This model was applied in case of Ziz basin in order to simulate and analyze the situation of water under different scenarios. The results show an increasing of demand for water irrigation and with introducing modern irrigation scenario. However, a decreasing trend in reservoir storage volume and groundwater storage was projected in Tafilalet.

Abstract The relationship between water abstraction and water availability has turned into a major stress factor in the urban exploitation of water resources. The situation is expected to be sharpened in the future due to the intensity of extreme meteorological phenomena, and socio-economic changes affecting water demand. In the city of Volos, Greece, the number of water counters has been tripled during the last four decades. This study attempts to simulate the city's network, supply system and water demand through a forecasting model. The forecast was examined under several situations, based on climate change and socio-economic observations of the city, using meteorological, water pricing, users' income, level of education, family members, floor and residence size variables. The most interesting outputs are: (a) the impact of each variable in the water consumption and (b) water balance under four management scenarios, indicating the future water management conditions of the broader area, including demand and supply management. The results proved that rational water management can lead to remarkable water conservation. The simulation of real scenarios and future situations in the city's water demand and balance, is the innovative element of the study, making it capable of supporting the local water utility.

This article reviews the potential use of charity records in reconstructing the lives of the poor in the early twentieth-century city and suggests how computer-assisted modes of quantitative and qualitative techniques of analysis can expand the known source base of research on poverty. Although the poor have themselves left only a small direct imprint on the historical record, the historian of poverty has managed to use the diverse and voluminous Victorian records generated by officials of the Poor Law which has resulted in a variety of administrative and institutional analyses of pauperism within various urban and regional settings. These studies have attracted a certain amount of criticism because of their dependence upon a narrow range of sources and orthodox historical methodology. It can be argued, however, that the full potential of Poor Law records in terms of what they contribute as well as what can be done with them has not yet been fully exploited. There is scope, for example, for the linkage of Poor Law material with demographic sources, such as the census enumerators' returns, to explore the geography of urban poverty in the nineteenth century. The value of Poor Law records would be enhanced if research questions could be phrased in relation to the socio-geographical context of the city, taking into account the dynamics of urbanism. For example, in Victorian and Edwardian Leicester it is possible to consider the consequence of socio-economic changes in a move from a domestic to a predominantly factory-based mode of production in the hosiery and footwear trades and the impact of the Poor Law during this transformation as patterns of discrimination characterized the provision of relief in certain districts of the town.

Economy System

This paper aims at comprehensively considering the mutual coupling between available water resources and water consumption in (i) a regional social economy system; (ii) a macro-economy system; and (iii) an ecological environmental system. The main focus is to investigate the impact of controlling the total amount of ET and to be able to utilize water resources efficiently. An analytic model for multi-objective decision making of water demand management based on ET indicator is developed in order to research the strategies and corresponding water demand schemes that are relevant to future objectives for economic development, agricultural development, ET regulation and control, water engineering investment, and water environment management of Beijing. Various scenarios examined in the study indicate the validity of the proposed method in analyzing water demand administrative decisions.

Industrial Demand

Abstract This study analyses the industrial demand for urban water using a panel dataset of firms operating in the city of Zaragoza (Spain) and looking at three sectors (manufacturing, construction and services) disaggregated on 24 subsectors. Evidence in favour of using the marginal price rather than the average price is obtained, and the selection of the price is found to influence the value of the elasticities. Based on a translog cost function, the direct price elasticity of water (−0.86), the output elasticity (0.73) and the cross-price elasticities between water and capital, labour and supplies (being all of them substitutes) were estimated. By subsectors, the influence of price is only significant in those with a higher share of water in the total production cost. These results indicate that pricing can be used as a tool for managing water demand by promoting conservation of the resource. However, these results also indicate that the simultaneous use of other instruments is advisable to reinforce the impact of pricing policy on water consumption.
