Nutrient enrichment of water resources has degraded coastal waters throughout the world, including in the United States (e.g., Chesapeake Bay, Gulf of Mexico, and Neuse Estuary). Agricultural nonpoint sources have significant impacts on water resources. As a result, nutrient management planning is the primary tool recommended to reduce nutrient losses from agricultural fields. Its effectiveness...

Many countries' water resources are limited in both quantity and quality. While engineering solutions can now safely produce recycled and desalinated water from non-potable sources at a relatively low cost, the general public is sceptical about adopting these alternative water sources. Social scientists, policy makers and technical experts need to better understand what is causing this lack of ...

Due to the frequent drought periods, water consumption increase, and competition of different water-using sectors, the Hirmand catchment is in a critical water status in the Sistan region. This threat has been intensified in recent years. To cope with this problem, we must pay more attention to different types of water use such as virtual water as a water saving method. The present study calcul...

The safety of groundwater resources is a serious issue, particularly when these resources are the main source of water for drinking, irrigation and industrial use in coastal areas. In Italy, 85% of the water used by the public is of underground origin. The aim of this report is to analyze the main factors that make groundwater vulnerable. Soil characteristics and filtration capacity can promote...

In some areas limited water resources combined with the fast growing population are leading to a crucial situation because of the increase in water demand. Besides, an estimated one billion people are living both without access to clean drinking water or electricity. Therefore, a stand alone photovoltaic-power based hybrid membrane desalination prototype has been designed to meet this challenge...

The purpose of the present study was the simulation of climate change effects on groundwater resources in Iran by using the dynamic systems approach. The approach was performed through system dynamics modeling process including problem explanation, system description, model development, model testing, and the use of the model for policy analysis. The impact of the application of various exogeno...

Irrigated agriculture in Idaho faces a decline in the availability of water and increasing costs for that available water. The demand for recreational and environmental urban water use continues to grow. Adopting improved irrigation technology is one of the few remaining alternatives that agriculture can use to address this problem. Development of large-scale water projects to enhance water sup...

Water resources are a key factor for regional sustainable development. However, the published water resource data in China is based on a large geographical scale, such as watershed units, and the data cannot reflect subtle differences in water resource distribution. The paper aimed to distribute water resources of the third-order basin of China into grid-cells of 1 km × 1 km. First, we used Mor...

this project aims at collecting and cataloging the information pertaining to the research projects and documents concerning water resource. the data collected along with abstracts were entered into worksheets in compliance with us- marc bibliographic format. they were fed into the computer following the necessary validation process. so far more than 5000 documents (proceedings, research report,...

In the past few decades, there have been extensive efforts on measuring sustainability. One example is the development of assessment tools based on sustainability indicators. Several individuals and organisations have suggested various indices for assessing sustainability. This paper focuses on the review of water sustainability assessment using the indicator-based approach. It discusses major ...
