Inputs:
Conversions:
| time of concentration (tc) | = | 0 | | = | 0 | minute |
| rainfall intensity (i) | = | 0 | | = | 0 | inch/hour |
| average overland flow path slope (S) | = | 0 | | = | 0 | |
| overland flow length (L) | = | 0 | | = | 0 | foot |
Solution:
| Manning's overland flow roughness coefficient (N) | = | HAS NOT BEEN CALCULATED | |
