New Orleans Flood Gates Hydraulic Model Study
A hydraulic model study was conducted to evaluate the forces exerted on selected floodgates by flowing water as the gates are closed after flooding has begun. The results of the study...

Hydropower
Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...

Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...

Hydraulic Fill Dam Made Earthquake Resistant
San Pablo Dam, near the San Andreas fault, constructed in 1919-21 by hydraulic fill methods, was found to be susceptible in places to liquefaction under seismic loading. The dam has been...

A Study of Inlet Control Alternatives for SWM
A laboratory study of alternatives for effecting inlet control on urban storm sewer systems for stormwater management (SWM) is described. The test facility was a full-size physical model...

Teaching Open Channel Design with Programmable Pocket Calculators
The goal of the basic open channel flow course is to present the theory of steady flow of water in open channels and some channel design practice. This paper presents the evolution of...

Microcomputer Simulation of Jets and Wakes
Illustrations are presented for radial jets and for turbulent flows in the wake of circular cylinders. The paper illustrates the use and importance of low-cost computational tools in engineering...

Microcomputers in Highway Drainage Design
This paper discusses some of the benefits and uses of microcomputers in highway drainage design and discusses the programs presently being developed. Subjects covered include hydrologic...

Predicting Overland Flow and Infiltration
The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply...

Designing for Residual Flooding
Flood control projects should incorporate designs and responses for flooding of the protected areas due to exceedance, overtopping, or failure of the features. Design strategies for levees,...

Tidal Flooding Study for a Seattle Watershed
The paper reports on a study to develop a correlation between rainfall volumes and tidal storm surges based on recorded rainfall and tide data. This correlation was used to establish tidal...

Flowfield Analysis with a Workstation
An engineering analysis workstation has been developed to expedite flow analysis. The workstation couples a microcomputer, a powerful numerical equation solver, and a versatile graphics...

Survey of Computer Use in Hydraulics and Hydrology
The surveyed population consists of the 58 member firms of the Consulting Engineers Council of Colorado practicing in the area of water resources. 90 percent of these firms use computers...

Friction in Hurricane Induced Surges
Bed shear stresses induced by the flowing water are expressed by means of a friction factor for which formulas are developed for: ocean bottom, mangrove fringes and areas, forested areas...

Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...

Encoder for Flood and Irrigation Data Transmission
This paper covers the design and use of a new dual parameter encoder for real time telemetry in the fields of flood forecasting and irrigation. Some history and background is presented...

Integration of Micro, Mini, and Mainframe Computers in WES Hydraulics Studies
The U. S. Army Corps of Engineers Waterways Experiment Station (WESA) Hydraulics Laboratory is involved in hydraulic studies of navigation and flood control projects of the Army Corps...

Application of Water Budget to Seepage Loss Estimation
The seepage loss for the emergency cooling water spray pond has been calculated by performing a water balance study for the pond. A field test of the spray pond was performed to estimate...

Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...

Modeling Hydraulic Problems Using the CVBEM and the Microcomputer
The Complex Variable Boundary Element Method (CVBEM) offers an effective and efficient means for modeling two-dimensional potential and related flow problems. The method has been applied...
