Grade-Control Structures for Salt River Channelization
Soil cement grade-control structures have been designed and constructed in conjunction with channelization projects along the Salt River in Phoenix, Arizona. The structures were designed...
The Secondary Inlet of the Eastside Pipeline Project
The subject of this paper is a design feature included in the current capital improvement program of the Metropolitan Water District of Southern California. This feature, the Secondary...
Dynamic Analysis of Multi-Pool Irrigation Canal
This paper discusses the dynamic characteristics of an open multi-pool irrigation canal from robustness point of view. In particular, the presence of right-half plane zeros in an open...
Sediment Transport Modeling for the Glen-Colusa Irrigation District Fish Screen Modifications
The Glen-Colusa Irrigation District (GCID) pumping plant is located on an oxbow of the Sacramento River approximately 100 miles north of Sacramento (Figure 1). The existing fish screen...
Monitoring Scour at Bridge Piers in Snohomish Co., WA
Washington State, Snohomish County Public Works Department is using a new Fixed Mechanical monitoring device, to augment its current program of monitoring scour at bridge piers. The Public...
Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...
Overview of the US Army Corps of Engineers Flood Control Channels Research Program
The objective of the Flood Control Channels Research Program, currently being conducted at the US Army Engineer Waterways Experiment Station, is to develop design guidance and systematic...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
Vegetative Roughness in Flood Control Channels
Laboratory flume tests and field evaluations were undertaken as a part of the Flood Control Channels Research Program to determine hydraulic roughness values for various types of floodplain...
Application of Regime Theory in Practice: A Case Study
Alluvial channels are known to adjust their slope, width, depth and velocity to achieve stable conditions given a supply of water and sediment. Scientific investigations of stable channels...
Channel Junction Effects in Channel Network Flow Simulation
In this paper, the momentum equations, which are applicable at channel junctions, are suggested based on the conservation of momentum flux. In the equation, the lateral inflow angles are...
Modeling Unsteady Open-Channel Flows Having Longitudinally Varied Fluid Density
Unsteady flows in waterways with fluid density varying longitudinally can be described by various sets of partial differential equations, according to conditions of density variation....
Applicability of Scour Equations in Tidal Areas
Bridge scour and waterway instability in the coastal region where waterways are subjected to tidal flow can be subjected to mass density stratification, water salinity, sedimentation (littoral...
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...
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...
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...
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...
Utilizing Geomorphic Analogs for Design of Natural Stream Channels
Engineering guidelines for the design of stable rock armored channels are well established. However, few guidelines exist for designers involved with the reconstruction of channels with...
Distributions of Return Flow in Navigable Waterways
Physical impacts of barge traffic on the riverine environment have drawn increasing attention from resource managers of the Upper Mississippi River System (UMRS). Return flow, which can...
Improving the Speed of Double Lockages
The size of tug and barge combinations on the Upper Mississippi River and Illinois Waterway frequently exceed the dimensions of the lock chambers they must pass through. The locks on these...
