Ma. Huston et Ta. Fontaine, PREDICTING TEMPORAL AND SPATIAL FLOOD DYNAMICS USING A PRECALIBRATED MODEL, Water resources bulletin, 30(4), 1994, pp. 651-661
A large storm in December 1990 allowed the evaluation of flood predict
ions from a hydrologic model (TOPMODEL) that had been previously calib
rated on the West Fork of Walker Branch Watershed, a gauged 37.5 ha ca
tchment near Oak Ridge, Tennessee. The model predicts both hydrograph
dynamics and the spatial distribution of overland flow using an index
based on topography. Maximum extent of overland flow during the storm
was determined from patterns of leaf litter removal from valley bottom
s. Both the flood hydrograph and the extent of overland flow were accu
rately predicted using model parameters obtained from a three-month pe
riod of normal flow conditions during 1983.
