Estimating Sediment Conveyance Capacity and Deposition Potential in Culverts
In watersheds characterized by high sediment production, culverts must be designed to adequately convey both water and sediment without causing excessive backwater upstream of the culvert...
Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...
Acquisition and Restoration of a Drainage District in the Snohomish River Valley
The purpose of this paper is to present an overview of the efforts by Snohomish County to acquire a drainage district (Drainage District 6) in the lower Snohomish River valley and restore...
Los Angeles River as a Water Source for a Freshwater Reservoir
Simons, Li & Associates, Inc., performed a study to examine the technical feasibility of a freshwater reservoir in the ocean at the mouth of the Los Angeles River through a conceptual...
Effect of Pump-Ins on California Aqueduct Water Quality
A model has been developed, based on the assumption of constant Aqueduct volume, to predict the effect of ground water pump-ins on Aqueduct water quality. Designated SuperCAMP (California...
Calibration of a Water Quality Model Using the Influence Coefficient Algorithm
A methodology based on the influence coefficient algorithm was established for the calibration of QUAL2E reaction coefficients. It was applied to the stream sections of the South Han River...
Water Resources Planning for the Fort Peck Indian Reservation, Montana
Water resources planning in Indian Country has produced varied results. On the Fort Peck Indian Reservation, the Assiniboine and Sioux Tribes are using an integrated approach to managing...
Regional Economic Impacts of a Land Fallowing Program?The Palo Verde Test Land Fallowing Program Case Study
The Metropolitan Water District of Southern California (MWD) and the Palo Verde Irrigation District (PVID) implemented a two-year test land fallowing program (Program) from August 1, 1992...
Third Party Impacts of Proposed Water Banking in the Colorado River Basin
Colorado River water is allocated to the seven Basin states based on a set of legal entitlements. Little flexibility is explicitly granted for addressing water shortages to particular...
Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...
Numerical Simulation of Hydraulic Jump
Hydraulic jump is numerically simulated by solving the laterally-averaged governing equations. The governing equations are derived for two-dimensional flow by laterally averaging the time...
Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...
Comprehensive Modelling of Water Distribution Networks
An analyst of a water distribution systems must frequently contend with a host of problems with very different time scales. Traditionally, such concerns have been accommodated by having...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
Bank Protection Toe-Downs and Local Pier Scour
The zone-of-influence for pier scour may impact bank protection toe-down depths. Countermeasures were required at a site along the Salt River in Phoenix, Arizona when the alignment of...
Design of Guide Banks for Bridge Abutment Protection
As an alternate to designing bridge abutments to withstand the development of the full scour prism predicted by equations currently available for estimating abutment scour, FHWA recommends...
Restoration Design for Urban Streams: Anacostia River Basin, Maryland
Several stream restoration projects have been undertaken by the Army Corps of Engineers in the Maryland portion of the Anacostia River basin. Measures used include bank stabilization,...
Retrofitting an Urban Watershed for Improved Water Quality
A study was conducted for the Baltimore County, Maryland, Department of Enviromnental Protection, to assess the watershed conditions and stream channel stability of Stemmer's...
Salinity Management for the Upper Gila River
Over development and over allocation of the limited water supply of the S afford valley in eastern Arizona has resulted in serious depletion of water for irrigation in the San Carlos Apache...
Derivation of New Dispersion Coefficient Equation for Natural Streams
A new simple method for predicting dispersion coefficient by using hydraulic and geometric data easily obtained in natural streams has been developed. Dimensional analysis was implemented...
