Forests for water: Exploring payments for watershed services in the U.S. south
The forested watersheds of the southern United States provide a number of benefits—including water flow regulation, flood control, water purification, erosion control, and freshwater supply—to the region’s citizens, communities, and businesses. The loss and degradation of forests can reduce their ability to provide these watershed-related ecosystem services. Payments for ...

What is the Geocell used for?
As a kind of building material, geotechnical materials have been used in European and American engineering buildings as early as the 1950s. Today, geotechnical products have developed into eight series: geotextiles, geogrids, geonets, geomatics(geosynthetic clay liner), geomembranes, geocells, geocomposite materials, and other related new geosynthetic products. Geocells has become more and more ...

The impact of water flow configuration on crystallisation in LiBr/H2O absorption water heater
Lithium Bromide (LiBr) strong solution entering the absorber tends to crystallise when the absorber temperature is increased for a fixed evaporating pressure. This is considered the key technical barrier for the development of a LiBr absorption heat pump water heater. There are several approaches to avoid the crystallisation problem, such as chemical crystallisation inhibitors, heat and mass ...

Seasonal water quality vs. flow relationships in a small regulated stream
The relationship of a water quality constituent with respect to flow measured at a stream monitoring station can give valuable information about the watershed and in-stream processes about the constituent in question. Seasonal dependency patterns often reveal relationships which would be unnoticed if all data are treated together. The aim of this study is to examine water quality constituent ...

Choosing DC valve actuators with the lowest energy consumption
Around the world there is a growing need for automated valve control in remote locations where mains electrical power is not available. For example, effective water management demands efficient and responsive flow control for applications such as groundwater remediation, irrigation and flood prevention. With perceived climate changes introducing more extremes of rainfall or drought conditions, ...
