Linear Programming Approach

In realistic water resource planning, fuzzy constraints can be violated but still allowed to certain acceptance degrees. To address this issue, in this study, a bi-objective pseudo-interval type 2 (T2) linear programming approach with a ranking order relation between the intervals is proposed for water system allocation. This developed approach can transform normal T2 fuzzy sets, including both trapezoidal and triangular types, into the bi-objective linear programming approach solved with the proposed algorithm with mathematical rigor, which improves the flexibility of the decision supports. The new model is applied in the utilization of regional water resource management in Xiamen city, China. Concurrently, a local water system model is established by considering the aspects of industrial, agricultural, and municipal requirements. Thus, by analysis of the solution algorithm, decision-makers can obtain different optimal results by selecting different acceptance degrees. The results also demonstrate the superiority of the proposed method. Therefore, this approach not only augments the theory of the optimal allocation method in water resource management, but also provides the support for meeting the requirements of the 13th five-year plan for Xiamen ecological planning.

Water resources in Tunisia are scarce and unevenly distributed between regions. As well, rainfall varies year-to-year. This study deals with the development of water resource management policies in Tunisia during the last five decades, starting with supply and mobilization management programs that transferred water resources from the interior to the coastal territories where the most important cities are and most economic activity takes place. This policy resulted in the establishment of an interconnected water system that remained in place until the end of the last century. The study also reviews the success of the demand management system the government has been forced by the increase in both urban consumption of water and agricultural needs to adopt. We also review the many challenges that set the current situation apart from previous periods of stress on the system, including high demand, climate change and social movements in the inner cities demanding the right for water, protected in the 2014 Constitution, be respected. The study highlights these challenges and suggests elements for a new resource governance that would draw on the accumulated good governance of the last five decades

Abstract Water Resources East (WRE) is a 180 strong and growing membership organisation established in 2014 to learn from international best practice on how to develop a more collaborative approach to water resource management planning to the 2050s and beyond. This is happening now in a unique region of England under significant pressure due to population growth, economic ambition, the need for enhanced environmental protection, and significant climate change impacts. The lesson of this chapter is the power of multi-sector water resource planning through collaborative and adaptable mechanisms led by integrated water resource management (IWRM). Through using active project case studies to gain insight into how we work with our members: Future Fenland Adaptation; Regional Natural Capital Planning through Systematic Conservation Planning (Water Resources East is teaming up with Biodiversify and WWF-UK, with financial support from the Coca-Cola Foundation, to develop a natural capital plan for Eastern England through Systematic Conservation Planning); and exploration of multi-sector finance of nature-based solutions through the creation of Water Funds, we hope to provide a strong evidence base for our sustainable and resilient methodologies and approaches that can be used, or be an influence on, other water management systems globally. Lastly, the WRE team and longest standing contributors reflect on lessons and recommendations from the past seven years of work.

Abstract Improving water resource management at a global scale is critical at this time. The risks to which bodies of water are currently exposed, whether due to climate change or anthropogenic conditions, affect water availability and quality in basins around the world. Nevertheless, water management has been revealed as a complex problem. In this light, one of the most promising methodologies is building dynamic simulation models, which may include the largest possible number of variables, not just hydrological. In this way, we may gain a broader perspective on all the natural and social dimensions encompassed in basins and, thus, improve decision making for the benefit of the population. This systematic review seeks to report the most representative results from several authors who have developed dynamic models applied to the management of water resources. Herein, special emphasis is placed on water resource management applied to basin models, decision making, and public policies, as well as on the modeling tools used and on model validation.
