EVALUATION OF 9 MODELS FOR UNGAUGED URBAN BASINS IN LOUISIANA

Nine flood-estimation models used for ungauged urban watersheds in Lou isiana were evaluated. Flood-quantile predictions from simple regressi on models calibrated by local data were found to be more reliable than those more complicated models or models with many parameters that may not be accurately estimated. Flood prediction from models developed b y using regionalization techniques were found to be reasonably good. F inally, application of a model outside of its limitations or domain ma y lead to substantial prediction error.
