Reservoir Sediment Sluicing?Laboratory Study
Experiments are being conducted in a 12.2 meter long, 0.38 meter high, 15 centimeter wide flume to examine the behavior of reservoir sediment deposits in response to sluicing. Crushed...
Drag Characteristics of Spheres in Bingham Fluids
R.W. Ansley and T.N. Smith's type of drag relation can be traced back closely, if not completely, to the Newtonian drag curve. The equivalent diameter for a sphere in a Bingham...
Gas Transfer at the Water Surface: Measurements of Gas Concentration Fluctuations
The paper describes measurements of fluctuating gas (oxygen) concentrations by means of a polarographic microscope near the air-water interface. The objective is to demonstrate the feasibility...
Hydraulic Effects on Swimming Fish in Fish Passage Structures
The implications of profile drag, weight, and buoyant forces on energy and power requirements of fish swimming through fish passage structures are considered. Where hydraulic grade lines...
Flow Through Fish Bypass Intakes
Hydraulic and computational fluid dynamic models were used to investigate the cause of the unequal intake flow distribution observed entering the three vertical intakes of the patented...
Design of Riprapped Scour Holes for Flip Bucket and Overfall Spillways
Presented in this paper is a simple method of predicting pre-excavated scour depths and geometry for riprapped basins below flip bucket spillways. The input data needed for establishing...
Task Committee Report on Reliability Analysis of Water Distribution Systems
The results of the ASCE Hydraulics Division Task Committee on Reliability Analysis of Water Distribution Systems are summarized in a very comprehensive report entitled Reliability Analysis...
New Methodology for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Components
A methodology is presented for the determination of the optimal timing for the rehabilitation/replacement of water distribution system components in order to minimize costs. In this model...
Submerged Flow in Parshall Flumes
Recent data collected in a 1-foot Parshall flume located in the Bureau of Reclamation's hydraulic laboratory indicate a significant discontinuity in the discharge/submergence...
Groundwater Transport in a Heterogeneous Aquifer: Tracking a Complex Plume
The Tennessee Valley Authority (TVA) is conducting a large-scale groundwater research project as a part of the Electric Power Research Institute's (EPRI) Solid Waste Environmental...
3-Dimensional Groundwater Modeling of the West Coast Basin Barrier
This paper describes a practical application of groundwater modeling of seawater intrusion in southern California. The West Coast Basin is one of the major groundwater reservoirs underlying...
Hydrodynamic Dispersion: Estimation and Prediction
The dispersion of dissolved, nonreactive tracers in groundwater is governed by diffusion and advection. A.E. Scheidegger introduced the term dispersivity to describe the effect that a...
Fractional-Step Method for Two-Dimensional Estuarine Transport
The fractional-step method was used in this study to split the longitudinal advective transport term from the other terms in the two-dimensional, laterally-averaged equation for estuarine...
A Numerical Solution Technique for Incompressible Flow
Presented is a numerical solution technique which employs the explicit predictor-corrector scheme of R.W. MacCormack in solving the governing two-dimensional equations of motion on a staggered...
An Error Analysis of the Dynamic Wave Model
The Dynamic Wave Operational Model (DWOPER) is used to forecast river stages on the Lower Columbia River. DWOPER was developed by the National Weather Service's Hydrologic...
Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...
A Phased Approach to Lunar-Based Agriculture
