Water is an essential substance in the global environment that sustains the functioning of all ecosystems. In fact, the demand for water resources should not be limited to human activity systems. In terms of sustainable development of the environment, the distribution and development of water resources need to expand to the needs of other ecosystems on the planet. Taiwan is surrounded by the sea and is a typical island-type economic country. However, due to the young geology of Taiwan, the terrain is too large and undulating, so that the rainwater quickly flows into the ocean and is difficult to store. Taiwan has an average of 2,500 mm of rainfall per year[1].The rainfall in Taiwan is more than 2.6 times the global average, it is a country with abundant rainfall. At the same time, there is also a crisis of water shortage. Due to the narrowness, the steep mountains, and the heavily rain of typhoon, it quickly flows into the sea. So that even if the rain is more and more in Taiwan, it will not ease the problem of water shortage. Therefore, the application of circular economy and water reuse is more important. This study takes “Flood detention pond in Maple Park” as the object of discussion. Exploring how the Taichung City Government used the ecological park to achieve the role of reservoirs for flood detention and disaster prevention. In addition, how to use water resources efficiently to achieve sustainable development has become a major issue in modern times.

AbstractIt is acknowledged that providing a safe water supply for all countries is one of the major challenges of the twenty-first century. Egypt is one of the greatest countries affected in Africa and Middle East. The Nile is facing a major water shortage due to the limited water resources and the the demand is growing as a result high population growth and development in industrial and agricultural sectors. This paper has been motivated by the fact that there is no up-to-date literature review of the optimal operation of Water Resources. The analysis of the reviewed literature is structured along five broad branches: (1) Mathematical Optimization Modelling Studies, (2) Numerical Simulation Modelling Studies, (3) Geographical Information Systems “GIS” based Studies, (4) Ecological Studies, (5) Water Reuse Studies. This review is limited to surface water but groundwater has been inexplicitly included. The paper concludes the best way to identify knowledge to cover the gap between water supply and demands and to guide future researches on water resources planning and management.

The role of river runoff resources is very important for Kazakhstan – the country located deep within the continent, with an arid climate, and experiencing water shortage. With such a geographical location, the hydrological regime of rivers is characterized by the considerable spatiotemporal variability, thereby complicating the water resousrces management. The issue of evaluating water resources is particularly relevant not only from a scientific point of view. In recent years, it has gained socio-economic and political nature due to the increasing role of anthropogenic factors (including geopolitical ones), as well as increasingly more noticeable changes in the global and regional climate. Based on hydrometric information using modern methodology, the water resources of eight water-resources basins (WRBs) on the territory of Kazakhstan have been estimated in the context of water-resources regions.

Rapid Evacuation

Oral and other modes of transmission that convey the experience of past disasters possess a vividness that cannot be obtained by disaster prevention education practices such as viewing hazard maps. Oral transmission is believed to have the capacity to induce rapid evacuation of people during disasters by acting on their emotions such as fear or anxiety. Meanwhile, the judgment, decision-making, or disaster knowledge of past disasters, has limitations such as the inclusion of inappropriate views from the standpoint of modern disaster management, or underestimation of the damage in the event of major disasters of an unprecedented scale, which can lead to a delay in evacuation. Disaster prevention education should adopt a “hybrid approach,” which combines oral transmission or other means that act on “emotions,” by providing a virtual experience of disasters and modern disaster-prevention knowledge, including hazard maps and teaching material, based on “reason.”

Wastewater Reclamation And Reuse

IAWPRC's Specialist Group on Wastewater Reclamation, Recycling and Reuse (Water Reuse Group) is conducting a day-long Water Reuse Seminar on August 1, 1990 at the 15th Biennial Conference in Kyoto, Japan. This paper is prepared to review the role of wastewater reclamation and reuse in water resources management in the U.S.A., and to serve as an introduction to the theme for the Seminar. Following a brief summary of available water resources in the United States, the role of wastewater reclamation and reuse is discussed in terms of planning and implementation. Major wastewater reuse categories are identified and discussed. The emphasis of this paper is on wastewater reuse in the context of the water supply benefits to water resources management rather than on water pollution control measures. The overriding importance in wastewater reclamation and reuse is to protect public health and to mitigate health risks. Accordingly, wastewater reclamation criteria for health protection are also presented.

Seawater Desalination

An integrated technical-economic modelling framework was developed to help planning and managing of water resources in a Mediterranean tourist area, Palma on Majorca island (Spain). Due to high water demand, groundwater resources are depleted and new water resources should be developed. Seawater desalination has become an important solution to water shortage, especially in the summer tourist season. Meanwhile, reclaimed water has been applied for agricultural and landscape irrigation. With regard to the treated wastewater not being effectively reused, further water reuse scenarios are envisaged in order to meet new water demand, restore over-exploited aquifers and reduce expensive seawater desalination. Three types of models were established and coupled: (i) hydrological models; (ii) water demand and/or need model; (iii) technical-economic model. In addition, a multi-criteria analysis completed the technical-economic modelling. The simulated water reuse scenarios are not alternative but complementary. They provide the possibilities for total reuse of wastewater in the Palma area. Compared with seawater desalination, water reuse is a cost-effective solution to address water scarcity issues in the Palma area. Using tertiary effluent for landscape irrigation allows over-exploited aquifers to recover. It is very attractive in terms of economic benefits and feasible with respect to technical and social aspects. Further water reuse for extending agricultural irrigation can greatly reduce seawater desalination but acquiring the farmers' agreement to give up pumping groundwater for irrigation would meet some difficulties. Water recharge would help to totally reuse wastewater but uncertainties related to public perception and the attitude or regulatory board and local authorities need dealing with. Because water reuse requires a long-term managing viewpoint in order to prepare and demonstrate its feasibility and security, seawater desalination was adopted as an emergency solution to meet peak demands during the tourist season and in case of drought.

Over Exploitation

The paper highlights and raises concern over issue of over-exploitation of groundwater resources in India, arising due to stress induced by growth in population and economic activity. The role of market and non-market interventions is analyzed to achieve a sustainable development of water resources, in particular groundwater resources. It is emphasized that the existing energy pricing structure portrays groundwater more as a social good and undermines the real economic value that needs to be attached to it. In view of the market and policy failures in overcoming the phenomenon of water scarcity, the role of institutions is reviewed in detail. Since efforts at the international level as initiated by the World Commission on Environment and Development, the UN Conference and the National Water Policy are largely in the nature of involving stakeholders in the conservation of water resources, the paper highlights the importance of evolving an appropriate participatory model of water resource management. The paper finally explores possible areas of research.

Textile Wastewater Treatment

Algerian water resources are scarce, and unequally distributed. The region is facing severe water shortage problems due to climate conditions, uneven precipitations, and the long periods of drought. Moreover, the demand for water from the urban population, industry, and especially agriculture is rapidly increasing. Water management represents an economic and ecological challenge to cope with this demand, conserve the water resources and reduce the environmental pollution. The present paper reviews the textile wastewater treatment and feasibility of reuse. The treatment was performed using a combined process; adsorption on bentonite (B) followed by electroflotation (EF). The effects of B concentration, pH, contact time and current density, were investigated under optimal conditions for maximal dye elimination. Water reuse activity, the potentials, risks and issued associated with reclaimed water reuse are also reviewed. The results were well fitted by both Langmuir and Freundlich isotherm models and show that the effluent treated by this combined method contained essentially no turbidity, color or COD 99, 01%, 99, 49% and 99, 8% are the removal rates obtained, respectively. The treated effluent quality satisfied the requirement of water discharges standards and integration of other factors is needed to reuse this water.
