2009/10/12
The Soil Conservation Service Curve Number (SCS-CN) method is a simple, widely used and efficient procedure for determining the expected amount of runoff from rainfall in a particular area. Its use, h...
A dynamic rating curve approach to indirect discharge measurement
dynamic rating curve steady-flow indirect discharge measurement
font style='font-size:12px;'>
2009/7/22
The operational measurement of discharge in medium and large rivers is mostly based on indirect approaches by converting water stages into discharge on the basis of steady-flow rating curves. Unfortu...
