Stable and Environmental Channel Design
The Wildcat and San Pablo Creeks Flood Control Project is located in Richmond, California. Both streams flow through a highly urbanized area, periodically overflowing their banks and causing...
Stable Channels with Loose Boundary
Recently, G. Parker suggested that the lateral transport of downstream momentum due to Reynolds stresses should be included in the momentum balance used to calculate the boundary shear...
Computer Aided Hydraulic Design of Open Channels
Over a 10 year period, the computer program, WASURO, was developed by the U.S. Army Corps of Engineers District, Los Angeles (LAD), which utilized many of the criteria of the previously...
A Lawyer's View of Engineers' Responsibility
When presented with a case involving damaged property, a lawyer typically will seek to determine the point of the failure and then work backwards in an effort to analyze each of the factors...
Litigation Support Investigations Involving Complex Flood Plains
This paper presents the case history of a devastating flood that occurred in a community located on a complex flood plain adjacent to a tidally influenced bay. Flooding resulted from cumulative...
Pinto Wash Alluvial Fan Litigation
This paper presents a case history involving flood/damage litigation brought by a downstream farmer against an upstream farmer and a local public irrigation district. The case combined...
Estimation of Urban Stormwater Quality
Two data-based methods for estimating urban stormwater quality have recently been made available - a planning level method developed by the U.S. Environmental Protection Agency (EPA),...
Instrumentation for a Dry-Pond Detention Study
A 12.3-acre, fully urbanized, residential land-use catchment was instrumented by the U. S. Geological Survey in Topeka, Kansas. Hydraulic instrumentation for flow measurement includes...
Applications of GSTARS Model
GSTARS is a Generalized Stream Tube model for Alluvial River Simulation. Depending on an engineer's need, GSTARS can be used as a fixed boundary as well as a movable boundary...
Two-Dimensional Numerical Modeling for Long-Term Sedimentation
Numerical modeling of long-term sedimentation processes in multi-dimensional models is computationally intensive and thus often uneconomical. A statistical superposition technique has...
Mathematical Modeling of Compound Channel with High Sediment Concentration
The mathematical model for erodible channels, FLUVIAL-12, has been extended to simulate the fluvial processes in the lower reach of the Yellow River in China. Fluvial processes in the...
The Bureau of Reclamation in Transition
Recognizing and responding to the changing climate in water resources, the Bureau of Reclamation recently launched a massive effort to redirect the agency's traditional mission....
Geotechnical and Hydraulic Stability Numbers for Channel Rehabilitation: Part I, the Approach
A model of incised channel evolution was developed to integrate the geotechnical and hydraulic factors that are involved in channel rehabilitation. Bank stability is attained when the...
Stratigraphy of Alluvial Fan Flood Deposits
The purpose of this paper is to describe an engineering geologic technique for assessing the frequency and magnitude of sedimentation events on alluvial fans. The technique is based on...
Design Depths and Velocities on Alluvial Fans
Under Federal Emergency Management Agency (FEMA) guidelines, flood depths and velocities on alluvial fans are determined by considering the probability of a given point on the alluvial...
Evaluating Flood Hazards on Alluvial Fans
In 1982, the Federal Emergency Management Agency (FEMA) developed a methodology for the determination of flood hazard zones and base (100-year) flood elevations on alluvial fans for administering...
Computations of High-Velocity Flows on Alluvial Fans
The results of numerical models of supercritical flows on alluvial fans demonstrate the strong effect fan topography has on flow velocity and depth. Particularly important are transverse...
Effects of Basin-Wide On-Site Stormwater Detention
The effect of basin-wide on-site detention of storm water runoff from developed areas is investigated to determine its effectiveness in reducing peak discharges in downstream portions...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Three-Dimensional Modeling of Cohesive Sediments and Pollutants in Surface Waters
Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating three-dimensional...
