Channel efficiency is a measure of the ability of a river channel to discharge water. Channel efficiency can be assessed by calculating the channel's hydraulic radius . The most efficient channels are generally semicircular in cross-section, and it is this shape that water engineers try to create when altering a river channel to reduce the risk of ...

Measure of the ability of a river channel to move water and sediment. Channel efficiency can be measured by calculating the channel's hydraulic radius (cross-sectional area/length of bed and bank). The most efficient channels are generally semicircular in cross-section, and it is this shape that water engineers try to create when al...
