Historical Rainfall-Runoff Analysis Using the Antecedent Precipitation Index
A long term simulation of rainfall-runoff can be used when analyzing the potential for economic benefits or flood damages to result from changes in the watershed, for developing discharge-frequency...
Evaluating an Autoregressive Model for Stream Flow Forecasting
Daily stream discharge generated by an Autoregressive Model is helpful in the design and risk assessment of temporary riverine construction projects. This case study uses actual daily...
Problems of Stream Flood Simulation and Prediction
The article presents a report on the natural flooding in a stream and the problems encountered when simulating and predicting stream floods. The complexity of flood characteristics, the...
Hocking River Sedimentation Study
The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However,...
Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...
Sediment Modeling in the Rio Grande Conveyance Channel
The Rio Grande Conveyance Channel and the Rio Grande Floodway convey water from the San Acacia diversion dam to Elephant Butte Reservoir. The Conveyance Channel was built in early 1950's...
An Interagency Overview of Selected Stream Sedimentation Models
The author's experience in developing stream sedimentation models is presented. The interagency study consisted of three phases. Phase one involved making an inventory of the computer...
A Watershed Model for Estimating Suspended Sediment Hydrographs
A mathematical model was developed to estimate soil detachment and transport and, consequently, suspended sediment hydrograph for single storms on a watershed basis. In this linear cascade...
An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...
Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...
Modeling Hydrologic and Pollutant Transport Processes for Stromwater Runoff to Surface Waters
Combined sewer overflows and stormwater discharges, which are considered point sources, and certain nonpoint sources (NPSs) display the characteristics of precipitation-driven events....
General Urban Runoff Model for Water Quality Investigations
This paper presents and examines a general urban runoff model appropriate for water quality studies. The model is applied to separate runoff source areas and the outfall conditions are...
Combined Stormwater Drainage and Treatment
Due to continuing public concern regarding environmental protection for the nation's waterways, new and more stringent water quality control regulations have been developed. This is most...
Development of an Experimental Watershed for Testing Nonpoint Source Pollution from Urban Runoff
The U.S. Environmental Protection Agency (EPA) National Pollution Discharge Elimination System (NPDES) stormwater regulation program prohibits non-storm water discharges into entering...
Strengths and Weaknesses of Shallow Water Equations in Steep Open Channel Flow
The paper evaluates the strengths and weaknesses of shallow water equations in steep open channel flow. These equations, 1) St. Venant equations, 2) steep slope shallow water equations...
Numerical Experiments on Instability in Unsteady Flow Modeling
The problem of numerical instability in modeling unsteady open-channel flows is investigated using the technique of numerical experiments. The model is based on the one-dimensional de...
Investigation of an Anisotropic k-? Model
In this paper the eddy viscosity hypothesis is abandoned and explicit expressions of Reynolds stress are deduced directly from the transport equations. Anisotropic k and ? equations are...
Considerations in 2-D Modeling of Hydraulically Steep Flow
Simplifications in the equations used to describe shallow water flow lead to some difficulties in modeling supercritical flow. The hydrostatic assumption produces two significant differences...
Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...
Numerical Modelling and Laboratory Verification for the Turbulent Flow Field in the Branching Channel
Adopting the depth-averaged k-? turbulence model and using the finite volume method and SIMPLE procedure, the turbulent flow field in the branching channel is numerically solved and verified...
