Development, Calibration and Application of Runoff Forecasting Models for the Allegheny River Basin
The computer program HEC1F, developed by the Corps of Engineers' Hydrologic Engineering Center, performs runoff forecasting. The focus of this paper is on application of HEC1F...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
Daily Suspended Sediment Model for Water Resources Management
A daily model of streamflow and suspended sediment (SS) concentrations has been developed to analyze daily suspended sediment records from tributary basins. The model provides a method...
Estimation of the Effect of Land Use Changes on Storm-Event Sediment Yield from a Small Watershed
The influence of partial deforestation in a small lowland watershed in the center of Poland on storm-event sediment yield is analysed. Rainfall-runoff model has been applied to estimate...
The Sediment Problem in South Africa Reservoirs
The reservoir sedimentation problem has been studied in South Africa from 1903 onwards. A substantial capacity reduction in reservoirs located in high sediment production regions has been...
Tapping A Glacier
The Eklutna water project receives a 1988 Outstanding Civil Engineering Award of merit. The project�a 30 mile pipeline and treatment plant that brings glacial runoff from Eklutna lake...
Baseflow and Beta Distribution
For water resources projects, design engineers are often required to separate total flow into baseflow and direct runoff. During such studies, baseflow is considered a crucial parameter;...
The Use of Distributed Rainfall-Runoff Models Based on GIS at Different Scales of Information
The effects of spatial variability of soil type and land use on basin response are investigated. This is modelled thorugh a distributed approach specifically designed for calibration from...
SWMM Application in Indian River County, Florida
The EPA's Storm Water Management Model (SWMM) was used to simulate drainage canal system network within Indian River County, Florida. Runoff and Extran module of the PCSWMM...
Comparison of Tenn-V and TR-55 on TVA Watersheds
The storm hydrograph simulation models TENN-V and TR-55 were compared as to their respective abilities to reproduce 468 storms observed on 54 watersheds. TR-55 did not represent the Tennessee...
Effect of Errors in Rainfall Measurements on Real-Time Forecasting Via On-Line Conceptual Models
The paper analyzes the issue of the choice between off-line and on-line use of lumped conceptual models for real-time flood forecasting. The effects of the adaptive use in the presence...
Spatial and Temporal Variations of Precipitation Effects on Storm Hydrographs
A partial area, variable source hydrologic rainfall runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics and several infiltration mechanisms....
Radar Rainfall Measurements and Runoff Forecasting
Rainfall varies in intensity and depth over time and space. Weather radar systems can provide estimates of rainfall at points in space with nearly continuous coverage with respect to time....
Issues of Detectability of Climate Change Impacts on the Runoff of a Southeastern River Basin
Can we detect and predict changes in hydrology caused by climate changes? Assuming credible predictions of climate change, can we predict corresponding hydrologic effects? Are uncertainties...
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
Effects of Runoff Changes and Sea Level Rise on Salinity in the Delaware River Estuary
The objective of this study is to investigate changes in the spatial distribution of salt in the Delaware Estuary resulting from climate induced changes in freshwater inflows and in the...
Special Hydraulic Problems Related to Coastal Louisiana Drainage Systems
The urbanized coastal areas of southeast Louisiana present unique problems for hydraulic engineers. These problems relate to the design of drainage systems serving leveed areas with flat...
Retention of the First Inch of Runoff in Coastal Areas
More and more state agencies are requiring development to retain the first inch of runoff from impervious coverage and release this runoff only through evaporation and/or infiltration....
Drainage Problems in a Highly-Developed Shoreline Area
Hilton Head Island, South Carolina, is a 42-square mile barrier island on the south-east coast Flooding of roads and properties is a continual problem in this low-lying, flat area due...
Two-Dimensional Inter-Rill Flow Model for the Analysis of Agricultural Runoff
This paper presents a model describing the flow field for the inter-rill component of agricultural runoff. Given rainfall intensity, surface roughness, rill spacing, and longitudinal and...
