SWMM Application in Indian River County, Florida
The EPA's Storm Water Management Model (SWMM) was used to simulate drainage canal system network within Indian River County, Florida. Runoff and Extran module of the PCSWMM...
An Ongoing Investigation of Residual Suspended Material Transport in Central San Francisco Bay, CA
A study of suspended material transport in San Francisco Bay, California, is presently underway by the U.S. Army Corps of Engineers. This paper describes preliminary numerical model and...
Experience with Cavitation in High Pressure Slide Gates
The Bureau of Reclamation has many years of experience in the design and operation of high pressure slide gates. This paper discusses the historical use of high pressure slide gates by...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Handling of Intake Bulkhead at King Talal Dam
During raising of King Talal Dam in Jordan in 1986, the existing intake wheel gate provided at the inlet of the project Low Level Outlet Works (LLOW) tunnel was found inadequate to withstand...
Model Study of Potential Debris Problems at the Proposed Diversion of Clover Fork River, Harlan, Kentucky
A study was conducted at the Waterways Experiment Station in Vicksburg, Mississippi, using a physical and a numerical model, to evaluate the entrance conditions at a proposed tunnel diversion...
Hydraulic Model and Prototype Experience on Old River Overbank Structure
Physical hydraulic model tests of the Old River overbank structure were conducted to investigate the hydraulic performance of the stilling basin and evaluate riprap stability and scour...
Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
Prediction Using Geostatistics and Mathematical Models
This paper discusses a new interpretation of geostatistical estimation and presents some thoughts on the meaning of probabilities in geostatistics and the role of mathematical models of...
An Overview of Coastal Stormwater Drainage Problems
Considerable studies have focused on the drainage design in upland areas. In the Atlantic and Gulf Coastal region, the stormwater drainage presents many unique problems mainly due to the...
Design of Expansions for Sub-Critical Open Channel Flow
Expansions for open channel flow at sub-critical velocity are required whenever it is necessary to reduce the velocity of flow from a structure which discharges into an erodible channel....
Borden Field Data and Multivariate Geostatistics
A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the...
Conditional Simulation of the Wilmington Sand-Shale Sequence, Los Angeles Basin
In shaly clastic reservoirs at a scale where vertical cross flow cannot be ignored the main source of heterogeneity is the apparent random geometry of the sand-shale sequence. That geometry...
Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...
Physical Modeling of Heated Discharges into a Stagnant River
An alternative cooling system study was performed for the Damietta Combined Cycle Plant in Egypt. The alternatives included spray canals, helper cooling tower and once-through cooling....
Self-Aerating Spillway Flow
The concept upon which most past analyses are based is that a continuum exists in aerated flow from 100 percent water, to air bubbles in water, to a water-air mixture, to an air-water...
Sediment Basin Design Using 2-D Techniques
A set of procedures for the design of sediment basins is outlined; it is based on two-dimensional hydrodynamic analyses, in contrast to conversional practice which has used only one-dimensional...
Overfall Stress and Pressure Distributions
The magnitude and distribution of hydraulic shear stress and pressure on the boundary of a straight drop overfall are presented for multiple overfall heights and flow rates. Hydraulic...
Energy Dissipation Structure for Fixed-Cone Valves
Results of a model study to investigate the hydraulic performance of a proposed energy dissipation structure for fixed-cone valves are presented. Procedures for estimating pressures and...
Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...
