Soil erosion in the riparian zone of the Three Gorges Reservoir, China

by IWA Publishing  (Mar. 19, 2015)

The riparian zone of the Three Gorges Reservoir (TGR) has experienced substantial erosion that may severely deteriorate the reservoir ecosystem. To calculate soil erosion characteristics, field investigations have been conducted in the TGR area and 12 erosion-monitoring transects have been set in the middle TGR. The results showed that the ...

Implementing contour bank farming practices into the J2000 model to improve hydrological and erosion modelling in semi-arid Western Cape Province of South Africa

by IWA Publishing  (Mar. 19, 2015)

Contour bank farming is a well-known agricultural management technique in areas which are characterised by intensive and erosive rainfalls. Contour banks are designed to reduce the flow velocity of overland flow and to intercept water before it concentrates in rills, thereby reducing the risk of soil erosion and land degradation. By their ...

Air pollution control is necessary for healthful environs and well-being. The Agency for Toxic Substances and Disease Registry states, “Pollution usually refers to the presence of substances that are either present in the environment where it doesn't ...

Chromium detection in water and soil...

by Camlab Limited  (Feb. 19, 2015)

What is chromium? Chromium is a metal that is widely distributed in the earth’s crust (soil and rocks), air and water. Naturally occurring chromium occurs mainly in the chromium (III) form as chromite ore, which contains oxygen, chromium (III) and other metals such as iron. Chromium (VI) compounds are produced commercially from chromite ...

Grounded: Why soil matters to the health of the planet and us

by Ensia  (Feb. 18, 2015)

The United Nations Food and Agricultural Organization has designated 2015 the International Year of Soils, and with good reason. As this infographic shows, a whopping 95 percent of our food comes from soil — and if sustainably managed, could produce 58 percent more food globally. There’s cause for concern, though. FAO concludes 33 ...

A comprehensive approach to reduce disaster risk in which care for people and nature go hand in hand

by Wetlands International  (Mar. 11, 2015)

Multiple times a year, severe tropical storms and typhoons hit the Philippines. Fortunately, the population is very resilient. After each disaster, they reconstruct their lives with creative solutions.

How mangroves help in reducing flooding and coastal erosion

by Wetlands International  (Nov. 13, 2013)

Inhabitants of low lying delta areas are particularly exposed to flooding and erosion caused by storms and hurricanes. These pressures increase with climate change and sea level rise. Coastal wetlands, such as mangroves, can play a key role in damage mitigation during disasters, as well as in stabilising coastlines. They also contribute to ...

A sheet erodibility parameter for water erosion modeling in regions with low intensity rain

by IWA Publishing  (Nov. 20, 2013)

Soil erodibility reflects the soil effect on the detachment process by rainfall and runoff; an evaluation of this parameter for single storm events was carried out using natural runoff plot data collected for two rainfall seasons in northern Iraq. The region is characterized by a semiarid Mediterranean-type climate with normal rainfall intensity ...
