Traditional conceptual rainfall — runoff models in the lumped form are usually developed without consideration of the spatial variation of rainfall and the heterogeneity of the watershed geomorphological nature. As an improvement to traditional [...]

Sediment budget analyses require watershed scale evaluation of road erosion and delivery. The Watershed Erosion Prediction Project (WEPP) model, as developed by the USDA Forest Service, simulates sediment detachment and delivery for a road, fill[...]

The frequency distributions and record heaviest snowfalls from snowstorms across the nation are defined. Data for 1948 — 2001 from 204 first-order weather stations identified major snowstorms in the United States, and these storm values were ana[...]

Small watersheds in urbanizing and suburbanizing regions are an increasingly important element of the flood hazard problem in the United States and abroad. This paper presents a methodology to estimate flood response in urban watersheds, with th[...]

This paper reviews the role of probability density function (PDF) choice on: (1) the statistical characterization of hydraulic conductivity; and (2) the estimation of the local-scale effective hydraulic conductivity. The most widely used skewed [...]

Hydrological models are often required to model watersheds where the conditions change over time. Calibration and validation of these models is a difficult process that requires validation of each of the major hydrological processes within the m[...]

Literature on the probability distribution function (PDF) of annual maximum flood discharges is extensive, yet the literature on the PDF of the flood of record (FOR) is sparse. This is partially due to two facts: (1) the PDF for record events is[...]

Many water users have been strongly encouraged to reduce the amount of their diversions through improved water management practices. However, the impact of improved practices can be lost in the uncertainty of measured water volumes. A firm under[...]

The performance of three artificial neural network (ANN) designs that account differently for the effects of seasonal rainfall and runoff variations were investigated for monthly rainfall-runoff simulation on an 815 km² watershed in central Okla[...]

The hydrologic design standards for urban drainage systems are commonly based on the frequency of occurrence of heavy rainfall events. Observations of recent climate history indicate that the frequency of occurrence of heavy rainfall events is i[...]
