Successful Use of Centrifugally Cast Glassfiber Reinforced Plastic (GRP) Pressure Pipes for Public Works in Sweden
Centrifugally cast GRP pipes were introduced in Sweden 17 years ago for industrial applications mainly as a gravity pipe. The process of pipe manufacturing as well as the pipe itself and...
Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...
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,...
Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
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...
Reliability Analysis of Water System Capacity
The paper presents, by means of an application, a few promising analytical methods for estimating bulk water system capacity reliability. In particular, this paper examines the applicability...
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...
Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....
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...
