Level Spreaders are measures that reduce the erosive energy of concentrated flows by distributing runoff as sheet flow to stabilized vegetative surfaces. Level Spreaders, of which there are many …

A level spreader is a constructed weir that is shaped or graded flat perpendicular to the direction of flow. Level spreaders are used to convert concentrated flow to sheet flow over nearly level areas without …

A level spreader is an erosion control device designed to reduce water pollution by mitigating the impact of high-velocity stormwater surface runoff. It is used both on construction sites and for permanent …

An overview of level spreaders and riparian buffers can be found in Urban Stormwater Structural Best Management Practices, AG-588-01, of the Urban Waterways series. This fact sheet provides more …

A level spreader is a permanent outlet for dikes and diversions consisting of an excavated channel constructed at zero grade across a slope that converts concentrated runoff to sheet flow and …

Level spreaders are an efficient way to disperse large volumes of stormwater in the least erosive way. They provide erosion control, promote water quality and infiltration and are often used in tandem with …

The width of the level spreader should be the greater of 300 mm or three times the diameter of the inflow pipe. The depth should be the greater of 200 mm or half the inflow pipe diameter.

A level spreader is an excavated depression constructed at zero percent grade across a slope. The level spreader changes concentrated flow into sheet flow and then outlets it onto stable areas without …

Level Spreader: The level spreader is a poured concrete weir constructed level (0% slope), and placed on an appropriate concrete footer. The level spreader should be designed and constructed to remain …

LEVEL SPREADER Definition A temporary non-erosive outlet for concentrated runoff, constructed to disperse flow uniformly across a slope.
