In this study, we calibrated and tested the Soil Conservation Service Curve Number 21 (SCS-CN) based Modified Sahu-Mishra-Eldo (MSME) model for predicting storm event total direct 22 runoff (Qtot) The MSME model satisfactorily predicted the estimated Qtot_pred for three watersheds, 23 unsatisfactory for one watershed. These results demonstrate MSME model’s potential to predict 24 direct runoff in poorly drained forested watersheds as reference for urbanizing coastal landscapes. 25 The flooding conditions of the lower coastal plain landscapes can be further exacerbated beyond 26 that shown by storm runoff-based flood discharges potentially due to ground water table rise as 27 sea level rises.
