Sediment Control Practices – Do they work? Daniel Kasapis Undergraduate Student, School of Civil Engineering, QUT. Abstract: As the world becomes increasingly aware of environmental issues, there is now a push towards the development of ecologically sustainable subdivisions. The planning stage of this type of subdivision relies heavily on the integration of transport networks with community facilities and dwellings in the area. By ensuring that a good network is in place, residents in the area would be encouraged to walk or ride a bike to places of interest such as shops or parks. Additional aspects that are considered in subdivision planning is the use of waste water treatment plants, storm water control devices and the construction of housing that conserves both renewable and non-renewable energy sources. Introduction In most modern land developments, various measures are used to prevent sand, soil and other sediments from reaching waterways. Yet marine pollution from land-based activities is recognised as one of the most serious threats to water quality and accounts for 77% of marine pollution in Australia ( Williams, 1996 ). From this one statistic, it could be assumed that modern sediment control practices are inefficient or functioning incorrectly. The fate of soil particles eroded from a hillslope is of interest to many sciences, engineering included as even a small amount of pollution from a site can cause significant environmental damage. While Erosion is a natural process and even land covered in native vegetation has erosion, earth working activities, dramatically increase erosion rates. As would be expected, the greater the area of site disturbance, the greater the erosion potential. Removal of the vegetative cover, including vegetation and topsoil, increases surface runoff and erosion potential. (citation) The aim of this paper is to determine the overall effectiveness of certain sediment control practices, as well as the importance of correct implementation and maintenance. Outlined are some of the most common sediment control methods, and an evaluation of their effectiveness is undertaken.

The Impact of Sediment Run Off The negative impact on aquatic organisms due to large influxes of sediment into streams or waterways is substantial. Even though mud and dirt are natural they are still serious pollutants that must be prevented
