the soil bioengineering is an applied science that it is the composition of structural, biological and environment concepts for soil erosion, sediment and flood control. biotechnical engineering techniques rely on biological knowledge to build geotechnical and hydraulic structures and to secure unstable slopes and banks. the largest enhancement in development of new soil bioengineering methods ...

Excessive sedimentation derived from anthropogenic activities is a main factor in habitat and biodiversity loss in freshwater ecosystems. To prevent offsite movement of soil particles, many environmental regulatory agencies mandate the use of perimeter silt fences. However, research regarding the efficiency of these devices in applied settings is lacking, and fences are often ineffective due to...

Changes in land use have generated a new landscape configuration in the Andino orobiome (mountain range) of the tropical Andes, resulting in a mosaic of cultivation and pastures interrupted by small fragments of forest and live fences. This has resulted in an ongoing decrease in the biodiversity of this biome. In the upper basin of the Cane-Iguaque River (Villa de Levya-Boyacá, Colombia), locat...

Stormwater runoff from construction sites has become an increasingly major contributor of fine inorganic sediment input into our streams and rivers. The negative impacts of excess fine sediment loads extend to all segments of the aquatic ecosystems from microbes to fish. While large construction projects represent single major potential pollution sources and are usually more visible, smaller co...

Temporary skid trail stream crossings have repeatedly been identified as having considerable potential to introduce sediment to streams. Forestry Best Management Practices (BMPs) have proven to be effective for controlling erosion and subsequent sedimentation, yet few studies have quantified sedimentation associated with various levels of BMPs for skidder stream crossings. Three skid trail stre...

In this study SiltSaver belted strand retention fence was compared with traditional type C silt fence with the goal of determining if it would be acceptable for use as a sediment barrier in Georgia. ASTM standard methods were used to evaluate flow through and sediment removal efficiency using three different site specific soils. For flow without sediment, there were no statistical differences, ...

The demonstration’s vehicle will be the multimedia performance «DE-FENCES», the outcome of the international «CUT Project», dealing with Europe’s new geography and questioning current «walls» and «separating lines» after the Fall of the Berlin Wall and the end of the Cold War, developed through Research and Residencies in former and present “cut” territories [Berlin, Palestine, Nicosia, Kosovo]...

In 2005, the US Environmental Protection Agency National Menu of Stormwater Best Management Practices, National Pollutant Discharge Elimination System Phase II for Construction Sites, listed compost filter socks as an approved best management practice for controlling storm runoff and sediment on construction sites. Like most new technologies used to control sediment on construction sites, littl...

Three studies conducted in Alabama evaluated impacts associated with a clear cut harvest in three physiographic regions. Machine impacts were assessed via tabulation of soil disturbance classes, measurement of bulk density and soil strength, or a combination of the two. Soil disturbance classes were similar among all locations with untrafficked areas comprising approximately 20 percent of the h...
