A significant challenge posed by changing climates is how water cycling and surficial and subsurface water availability will be affected at global and regional scales. Such alterations are critical as they often lead to increased vulnerability in ecosystems and human society. Understanding specifically how climate change affects water resource variability in different locations is of critical i...

Efficient use of the water resource requires internalization of all costs in the price of water, including environmental and resource costs. However, water resource management tends to be highly political and increasing water prices are a sensitive and complicated policy matter. Hence, there is a need for increased understanding of the implementation process and the attitudes towards implementa...

[1] Freshwater scarcity has been cited as the major crisis of the 21st century, but it is surprisingly hard to describe the nature of the global water crisis. We conducted a metaanalysis of 22 coupled human–water system case studies, using qualitative comparison analysis (QCA) to identify water resource system outcomes and the factors that drive them. The cases exhibited different outcomes for ...

Reliable sensor values are important for resource-efficient control and operations of wastewater treatment processes. Automatic fault detection methods are necessary to monitor the increasing amount of data produced in any modern water resource recovery facility (WRRF). Most on-line measurements exhibit large variations under normal conditions, due to considerable variations in the influent flo...

The WETnet concept exists at the intersection of three familiar areas of interest as depicted in FIGURE 1. The concept is analogous to replacing the hardware and software domain with, say, transportation and lodging, and the intersection would then be a conference. That is to say that when you get a group of people who share a common interest to meet, discuss, and share their ideas then we gene...

Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

In this paper, we design a water resource allocation mechanism which plays the role of incentives for promotion of the water use efficiency and productivity by taking water distribution for enterprices as an example. It firstly divided the water allocation problem into three cases according to the relationship among amounts of water allocatable and demanded for enterprises. By discussing the th...
