Rainfall-Runoff Modeling for Watershed Stormwater Management
In the design of watershed stormwater management plans used for land development, the Pennsylvania State Runoff Model (PSRM) presents upstream subbasin flows that contribute to the peak...
Simulation of Channel Changes Induced by a Reservoir
A fluvial study was made for potential stream channel changes induced by a reservoir. It is generally recognized that a reservoir induces sediment deposition along the upstream channel...
Santa Ana River Mainstem Project
The Santa Ana River Mainstem Project consists of seven major features including the construction of 550 ft. high earth and rockf ill dam; raising the embankment by 28 feet of Prado Dam,...
Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...
Scour around Exposed Pile Foundations
Laboratory experiments were conducted to measure local scour around exposed pile groups for a variety of conditions including different spacings, different skew angles, different patterns...
Discussions of a 3D Numerical Simulation of Transient Regional Groundwater Flow and Transport
A 3D numerical model of a groundwater flow and transport was developed to study the movement of radionuclides in the Savannah River Nuclear Site, South Carolina. The modeling effort has...
Mitigation of Flood Hazard on Alluvial Fans
A number of investigators have suggested that the limits of the traditional, stochastic, one-dimensional model of alluvial fan flooding have been reached and that there are one- and two-dimensional...
Mexican Border Ground Water Agreement
This paper provides a discussion about the challenges in developing a Mexican Botder Ground Water Agreement for the management of shallow ground waters that connect to the surface water...
Portable Flumes with Adjustable Throats
Vertically adjustable flumes for canal flow measurements address several problems in field practice. One involves the perception by some canal water users that flumes and weirs always...
Hydraulic Design of Subsurface Flow Wetlands
Although Subsurface Flow Wetlands (SFW) have received steadily increasing international attention during the past 10 to 15 years, comprehensive design criteria are not available for some...
Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...
Glacier-Generated Floods and Debris Flows
Sudden release of glacially impounded water causes catastrophic floods, known as outburst floods, and ocasionally spawn debris flows that pose significant hazards in mountainous areas....
Temporal Development of Local Scour at Bridge Piers
The temporal development of local scour depth at circular cylindrical bridge piers is considered. New data are presented and used to quantify the influence of flow duration on the depth...
Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...
Research to Application: Network Models to Simulate Flow and Transport in Heterogeneous Media
Effective groundwater cleanup requires accurate site-specific information on cleanup processes. Numerical simulations limit the need for expensive field experiments and provide details...
Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...
European Progress on river Renaturalisation
Most restoration projects in Europe have been designed to maximise species richness with little regard for channel stability. To recreate a sustainable natural channel it is necessary...
Role of Vegetation in Hydraulics of Channel Restoration
Boundary layer theory is used to develop a backwater model for flows through vegetated waterways which can be employed to approximately estimate flow depth variation in channel restoration...
Modeling 3D Free Surface Flow in Compound Channels: A Validation Case Study
This paper presents the results of a validation study of a free-surface flow model. For the validation, experimental data collected in a compound open channel is used. This validation...
Groundwater Flow Component of a Wetland-Dynamics Model
A 3-D groundwater flow model was developed to study the hydrology of groundwater-fed wetlands. Initial model results, including steady and unsteady simulations, compare well with existing...
