Quantitative changes in groundwater and crises resulting from uncontrolled water extraction have turned water resources management into one of the supply-demand dilemmas in arid regions. The present study evaluated the quantitative situation of water resources in the Ardestan Plain adjoining the Ardestan desert by using the MODFLOW mathematical model. Simulation of groundwater flow in the stead...

The Water Framework Directive is a major regulatory reform of water resources management within the European Union. Integrated catchment management plans must be prepared for all river basins, in order to achieve 'good ecological status' in all EU waters. Ecological status is a broader measure of water quality than the chemical and biological measures that were previously dominant. The Directiv...

— Decentralized governance of water resources is a centerpiece of Mexico’s neoliberal reform strategy. We analyze decentralization based on urban/rural case studies in distinct geographical regions to ascertain whether it is linked to more efficient water management or sustainable use of water resources, and to examine its development implications. We assess whether or not private sector manage...

South Africa has adopted an ambitious new water legislation that promotes equity, sustainability, representativity and economic performance through water management decentralization, new local and regional management institutions, water users’ licensing, and the possible emergence of water rights’ markets. This paper addresses the diversity of water users and uses that currently exists in rural...

Integrated Water Resource Management (IWRM) aims at finding practical and sustainable solutions to water resource issues. Research and practice have shown that innovative methods and tools are not sufficient to implement IWRM - the concept needs to also be integrated in prevailing management paradigms and institutions. Water governance science addresses this human dimension by focusing on the a...

nowadays, it’s very usual to use these models in almost all sciences. use of these models has provided quick, appropriate and economic answers to many questions. modeling is developing in different fields of agriculture, including irrigation and drainage. field tests are useful to determine and analyze the different irrigation management but there are significant limitations. the most important...

transfer-transport of the waste is one of key functional elements in solid waste management from technical and financial viewpoint. unfortunately very few reach activities has been conducted in this field regarding local characteristic of phenomenon which urges undertaking local surveys and research projects. tehran organization of waste recycling and composting has decided to investigate diffe...
