In-canvas, visually inspect inlet capture, spread, and bypass. On a selected inlet's asset card, under Analysis, see inlet data, including runoff coefficient, design flow, intercepted flow and efficiency rating (percent). Drainage Design re-calculates data in real time, as you adjust placement or size of inlet.
Select an inlet to view the analysis of its performance:
Inlet analysis occurs in real time, as you work. When you move an inlet or adjust its size or material, analysis reflects these changes in-canvas and on the asset card.
Inlet Analysis takes into account differences in runoff coefficients for different kinds of materials used in a component road. In the comparison below, the analysis data on the asset cards show the affect of replacing a sloped asphalt median with a grass median for an otherwise, identical inlet and conditions. Note that the spread value using asphalt exceeds the recommended allowable spread (red area). In this case, switching to a grass median corrects this condition.
