Bootstrapping Nonlinear Storm Event Models
A bootstrap method for estimating the parameters of nonlinear storm event models is presented. The method pools (combines) the parameter estimates obtained from fitting computed and observed...
Paleoflood Hydrology and Design Decision for High-Risk Projects
Paleoflood hydrology is not merely one of several alternative methods for risk-based design. Rather, certain kinds of accurate data on the largest paleofloods of recent millennia provide...
A Regionalized Rainfall-Runoff Stochastic Model
The single area unit hydrograph model is used to develop a distribution model which accommodates the uncertainty in rainfall over the catchment. By categorizing the available rainfall...
Extraordinary Floods in Arid South Africa
South Africa, a country where 65% of the area receives less than 500 mm of rain annually, has experienced many major floods during the last century. The importance, aim and scope of the...
Rainfall-Runoff Forecasting of Desert Flash Floods
A distributed, physically-based rainfall-runoff model has been applied to a 150 km2 semi-arid watershed, and model accuracy is being evaluated with...
