| Abstract |
| Delivery ratio (DR) is a barometer to evaluate runoff characteristics of pollutants within basin areas. DR is critical to determine water quality target and allotment loads in the process of setting up basin management plans such as TMDL. Unfortunately, however, calculation of DR under the condition of standard flow and that in unobserved basin is difficult in korea because of a lack of data. As for DR of independent basin about which validation data was obtained, utilization of basin model such as BASINS/winHSPF is reasonable to reflect daily flow. And as for others with few data, regression obtained according to land use type is available. DR of dependent basin should exclude influence of upstrem basin. Thereby, it is required to select model which is able to calculate delivery by tributary as well as net delivery load via sheet flow. |
