Water management controls – for concentrated waterflows
Control of water runoff or concentrated water flows is one of the most important erosion control measures. Water management control practices help to reduce water velocities (speed) and to minimise contributing catchment areas. The overall goal is to minimise sediment generation.
Water runoff can either be ‘clean’ (which means, there is no sediment) or ‘dirty’ (there is sediment). In an ESC context, ‘clean water’ has usually come from above a work site and not run through the works area. ‘Dirty water’ has run through a works area and needs treatment before it is discharged.
Each control or measure is described for all stages of the project’s design, construction, operation, maintenance and decommissioning.
