The springs of Aravissos gush out at the south foot of mount Paiko. The water resources of these springs are used mainly for covering the necessities of the city of Thessaloniki. For this purpose Thessaloniki Water Supply & Sewerage Company (ΕΥΑΘ) constructed, two decades ago, the pumping-station of Aravissos. This paper presents the results of the research conducted for the study of the recharge - operation mechanism of the springs and the potential of the water supplying aquifer. For the study of the recharge - operation mechanism of the springs we evaluated data coming from the extensive drilling programs conducted in the area and from the substantial bibliographical references. Respectively, for the study of the water supply potential of the aquifer we evaluated the data coming from gradual pumping of the pumping-station's drillings and from the flow measurements of the spring gushing out at the study area. The contribution of this study on the management of the water supplies of the karstic aquifer of Aravissos can become determi natively important.

Beijing is located in a semiarid region, and water shortage is a common problem in the city. Along with the rapid increase in water demand, due to fast socioeconomic development and an increase in population, a shortage of water resources and a deterioration of the water environment have become obstacles to sustainable socioeconomic development in Beijing. In the long run, sustainable water resources management, water conservation, and completion of the south to north water diversion project will solve the problem. This paper introduces the water resources situation in Beijing; analyzes future water demand; and discusses the actions of water saving, nontraditional water resources exploitation, wetland construction, and water environment protection. The paper also explains the importance of the south to north water diversion project and the general layout of the water supply strategy, water distribution system, and methods to efficiently use the diverted water in Beijing.Key words: water resources, water supply, water saving, water recycling, water diversion.

Semi Arid Region

Located in a semi-arid region in the south and east of the country, the Moroccan oases are characterized by severe aridity and scarcity of water resources. However, the ancestral populations have shown a major form of adaptation to aridity constraints through the development of knowledge and heuristic expertise on a traditional water supply system called ‘Khettara’. Currently, the effects of climate change on the one hand and the deep social, cultural and economic transformations on the other, have caused the productivity of traditional agriculture to no longer match population needs with progressive vanishing of Khettara as its consequence. A diagnostic study of the situation of oases conducted in the south of Morocco makes it possible to address the socio-economic, environmental and cultural aspects by developing and using a specific methodology to assess fragile ecosystems (DPSIR: Driving Force-Pressure-State-Impact-Response). The main aim of the present work is to provide a methodology allowing the formulation of the required knowledge for the mobilization of traditional water resources techniques such as Khettaras, in order to maintain the national heritage of oases. The modeling formalism of UML (Unified Modeling Language) is borrowed from information technology for the purpose of standardization. The developed methodology enhances these traditional water supply systems by combining traditional and modern techniques to increase their performance in terms of reduced maintenance costs and increased productivity. The developed methodology has been applied to a real case characterized by extreme aridity.

Singapore's water resources system is a strong illustration of the value of an integrated water resources management in urban enviroments. Today, urban water resources planning and environmental engineering are essential partners in the planning of tomorrow's urban environments - and not just as passive projects unnoticed by the public. In Singapore we can see the specific evolution from the separate development of water catchments and the control of monsoon flooding to the integrated water management strategy as exemplified today in the Marina Barrage. The multi-purpose project boosts Singapore's water supply by creating its first reservoir in the city, helps flood control and enhances the living environment of the city. Marina Barrage presented many interesting challenges in the development of a project whose impact was designed to far transcend the normal functional aspect of a large public works project. This paper will present the many potential public uses that were considered in the planning for the final facility. The motivation is that the 3P (people, public and private) sectors play an important part in sustaining water resources. Instead of designing the Marina Barrage as a conventional functional facility accessible only to operational staff, the project breaks new ground in taking an unconventional design approach. The facility was designed as an open facility to engage and inspire the public to care for water. Features for public education, lifestyle attraction, eating experiences, options for families to relax, play areas for children, attractions for overseas visitors, spaces for dedicated conferences and many more were considered. A multi-functional team of interior designers, landscape architects, researchers, art specialists, lighting specialists, environmentalists, etc was assembled and met continually as the design evolved. These evolving goals had to be integrated into the overall functional characteristics of the barrage. The resulting project is a world-class example of how a project initially conceived for water resources functional purpose can evolve not just into an iconic structure but one whose multi-functional capabilities have attracted huge attention from tourists and the people of Singapore. This is evidenced by more than 250,000 people visiting the facility in its first 6 months of operations, and the many families who spend relaxing time enjoying the various spaces at the Barrage. The evolution of the Marina Barrage in design and operation can act as a lesson for other cities considering similar large flood control or water supply projects. The success of the Marina Barrage's 3P mission indicates how for a relatively little increase in cost these facilities can play a major role in enhancing urban lifestyle in sustainable cities.

AbstractLibya's further economic development depends on the careful use of its coastal aquifers and the economic exploitation of the substantial but remote groundwater resources of the south. The former have been seriously impaired by over-use and the Libyan government has decided to assure water supplies for agriculture, industry and for urban use by moving up to 3 km3 per year of fossil groundwater to the Gulf of Surt and later to the Gefara Plain. The article discusses the scope and significance of the plans and comments on the agricultural implications and the likely ultimate use of the water.

The total population Bontang in 2014 is around 187,346 peoples. With the level of domestic water demand of 110 liters /person/day, the water needs of the city for at least Bontang 238.52 liters/sec. Currently for the needs of the community water supply received from the local water company with a capacity of 80 liters/sec, and It will be developed further to 250 liters/second in 2015. There are two big industries that need huge of water, namely LNG and Fertilizers Factory.  Factory of East Kalimantan (PKT) need additional water supply around 1000 m3/h or (166.67 liters/sec) with the specifications for the Water Industry   and 200 m3/h will be used to supply the needs of water for 21 818 inhabitants. Bontang city water source can be derived from groundwater, rivers, and rain water storage (reservoirs of water). In recent decades Bontang relied upon groundwater for water supply industry and some communities, the rest use river water and rain water tandah. With a very heavy rainfall ( 2500 mm / year), then the making of ponds in large quantities can help to reserve water in the future. For the purposes of future water supplies, it would require an asessment of all potential water resources utilization and planning for the use of adapted to the urban development plan. Water recycling of domestic waste is also a potential source of fresh water in the future, especially for industrial use. The drainage system needs to be directed at a large holding pond located in a low area, before going into the sea. The rain that fell in the city drained and collected would be of potential if utilized. In short-term utilization of water of the Bontang river is very of potential, given its location in the city center and is one of the many watersheds in Bontang, causing floods in the rainy season. Control and management of water is needed to support the use of river water.Keywords: Water resources, Water Demand, Water Supply, and Water Balance

This article reports the findings of the fieldwork exploring the cisterns at the Bisti promontory of Hermione, executed as part of a collaboration between the Ephorate of Antiquities of the Argolid and the Swedish Institute at Athens. In order to better understand the function of the cisterns within the water supply system, the article begins by presenting an overview of existing water resources in the area, primarily the naturally occurring sources and the city’s 2nd-century AD Roman aqueduct. Following this the study describes the remains of the 14 potential cisterns on the Bisti. Based on the empirical material the similarities and contrasts between these are explored, as well as what they can tell us about the history and life in ancient Hermione. In particular, the article suggests that the presence of the cisterns contributes to our understanding of the urban fabric of the city, and reveals important information about when the city was moved from the Bisti to the nearby Pron Hill.

The site of New Pleurona, a well fortified city of the Hellenistic period, is located in the western part of Greece. Archaeological and geophysical evidence indicates that the city, during its existence, was connected to the sea. The geomorphological changes are linked to the delta's progression of the two neighboring rivers, Acheloos and Evinos. In addition to the city's impressive fortifications, Pleurona had an extensive network of water supply and storage, including one of the most impressive cisterns of the ancient world. The case of Plevrona can be viewed as an example of adapting a city's needs through environmental changes and as a best practice in the use of its water resources.

The Future

The ANEMI model is an integrated assessment model of global change that emphasizes the role of water resources. Securing water resources for the future is a key issue of global change and ties into global systems of population growth, climate change carbon cycle, hydrologic cycle, economy, energy production, land use and pollution generation. The focus of the presented work is on the development of global water supplies necessary to keep pace with a growing population and global economy. With the structure of the ANEMI model, a series of experiments are conducted in order to assess: (i) the current role of water supply in the global Earth system; (ii) the level of water stress that can be expected in the future; and (iii) what are the potential effects of water quality on global surface water supply and the distribution of water supply types. The results of model simulations show that surface water resources were sufficient to meet the water demand and water quality is not shown to be a significant factor for the development of surface water supplies. Due to globally aggregated scale, these impacts are averaged and likely understated.
