Subsidence of peat soils in South-East Asia – Flooding risks in Sarawak

by Wetlands International  (Nov. 10, 2014)

There is an increase in awareness of the carbon emissions resulting from peatland drainage and peat fires. There is in general however a lack of recognition of the link between carbon loss and peatland subsidence, i.e. lowering of the soil surface. This paper presents the case study of the Rajang Delta in Sarawak, Malaysia where peatland ...

Subsidence of Peat Soils – Flooding Risk in South-East Asia

by Wetlands International  (Jun. 16, 2014)

There is an increase in awareness of the carbon emissions resulting from peatland drainage and peat fires. There is in general however a lack of recognition link between carbon loss and peatland subsidence, i.e. lowering of the soil surface. In the tropics the process of subsidence after drainage is very fast due to high temperatures. Flood risks ...

Mangroves for coastal defence

by Wetlands International  (Nov. 6, 2014)

The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the ...

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 ...

Using Coir Geotextiles for soil erosion control

by CoirGreen  (Aug. 11, 2012)

One of the most effective and yet natural soil erosion prevention techniques is the use of Coir Geotextiles fabrics ( Woven Geotextiles). Used extensively to prevent environmental degradation Geotextiles have no synthetic material but is instead made out of an organic fiber, coir, which is extracted from the husk of a coconut. It is strong, ...

ArmorMax® is Solution for Alberta, Canada Transportation case study

by Propex Operating Company, LLC  (Sep. 23, 2014)

Background In Alberta Canada. Alberta Transportation identified two ditches. H614:02 north ditch and H894:04 east ditch that had experienced severe erosion.

Sandbags help in the aftermath of wild fires which create flood & erosion risks

by Barrier Systems, LLC  (Aug. 13, 2013)

With all of the wild fires we have seen around the country this year and in the past, the potential of significant flooding and erosion become a valid concern. Hillsides and slopes once covered by vegetation and trees are reduced to dirt and ash. When rain events happen on these denuded areas, there is nothing to help retain the water and slow ...
