    Introduction There are two main ways in which erosion occurs. One is a natural process in which the landscape is impacted upon by weather events and the landscape is gradually changed over time. The other is an accelerated anthropological process which occurs when land is cleared, modified and exposed to rain, wind or waves. If no precautions have been taken, this process will cause excessive removal of soil particles from one area to another and this can have serious environmental, economic and social consequences.

    Erosion and Sediment Control Guidelines for the Built Environment, Service Corridors, Transport Corridors, Broadacre Agricultural Farming and the Rehabilitation of Old Infrastructure and the associated Technical Notes will provide a valuable resource in helping to plan, control and limit the impact of erosion and sedimentation. These guidelines each focus on the particular erosion and sediment issues which may arise with developments within these areas and provide information for the preparation and implementation of Erosion and Sedime
