Water resources worldwide require management to meet industrial, agricultural, and urban consumption needs. Management actions change the natural flow regime, which impacts the river ecosystem. Water managers are tasked with meeting water needs while mitigating ecosystem impacts. We develop process-oriented advection-diffusion-reaction equations that couple hydraulic flow to population growth, ...

Seasonal variability impact on livestock production and management stems from poor pasture quality and quantity as well as shortage of water. During wet season, there is usually sufficient quantity of pasture in good quality for animal consumption; but during dry season, there is always insufficient pasture as well as shortage of water for livestock consumption. As a result of these, exploratio...

Environmental issues related to desalination are a major factor in the design and implementation of desalination technologies. An acceptable desalination plant is expected to meet environmental regulations; be cost-effective in terms of construction, operation and management, as well as the costs associated with monitoring and permit fees. Some major environmental concerns include issues relate...

The consumption of bottled water has been increasing consistently over the last decade, even in countries where tap water quality is considered excellent. This paper discusses some of the reasons why people decide for an option that is often more expensive and less comfortable than tap water. Consumer surveys usually stress two main factors: dissatisfaction with tap water organoleptics (especia...

Access to safe and reliable drinking water is commonplace for most Canadians. However, the right to safe and reliable drinking water is denied to many First Nations peoples across the country, highlighting a priority public health and environmental justice issue in Canada. This paper describes trends and characteristics of drinking water advisories, used as a proxy for reliable access to safe d...

We examine factors that explain consumer spending on tap water substitutes using information from a national survey undertaken with a representative set of Canadian respondents. We develop a model to predict the percentage of households that undertake such spending for the purpose of reducing perceived health risks from tap water consumption. Using results from the model we estimate the magnitu...

Over the past several decades, rocky desertification has led to severe ecological problems in karst areas in South China. After a rocky desertification treatment project was completed, the vegetation coverage changed greatly and, consequently, increased the ecology water consumption (approximately equal to the actual evapotranspiration) of the regional vegetation. Thus, it intensified the regio...
