Failure of a Large Reinforced Concrete Pipeline
This paper describes the damage that occurred when a landslide overloaded an 11 ft diameter reinforced concrete pipeline. The 8 ft lengths of pipe, each of 11. 5-in. wall thickness, were...

Alternative Approaches for Waterhammer Analysis and Pipeline Protection
This paper provides a brief review of typical waterhammer problems and their solutions for pumping systems. Alternative approaches to identify and resolve design problems are discussed....

A Practical Approach to Selection of Waterline Materials for Use in Expansive Soils
The authors previously investigated the performance of asbestos-cement, polyvinyl chloride and ductile iron pipe in the expansive soil environment. Expansive soil forces on the pipe were...

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...

Microcomputers in Domestic Water System Evaluation
Water system hydraulic network analysis can be accomplished rapidly and accurately using microcomputer systems affordable by engineering firms and staffs of major water utilities. Simulations...

A 1-D Saltwater Intrusion Program on the IBM-PC
A one-dimensional finite element program has been developed for use on the IBM-PC as an aid to teaching groundwater hydrology to students. The program uses linear elements and the Galerkin...

An Operational Dynamic Routing Model for Small Computers
The paper reports on a study to develop an efficient dynamic routing procedure that can be used on an IBM PC/XT microcomputer as the routing component in a comprehensive watershed simulation...

Floodplain Modeling for the Henry Street Basin
A study focusing on the primary conveyance system in the 5. 7 mi**2 Henry Street Drainage Basin in Hillsborough County, Florida was conducted to develop remedial measures for the control...

Estimating Peak Flow Reduction in Small Reservoirs
A microcomputer program is used to provide a simple and rapid estimate of the peak outflow from such reservoirs. Peak flow values, determined by flood frequency analysis or regional flood...

Comparing Flood Stage-Discharge Data?Be Careful!
A long term stage-discharge record is extremely valuable data. However, simplified applications of long term records to draw sweeping conclusions about man's effects should be avoided,...

Computerized Information for Selecting Protected Streamflow
For developing criteria for protected flow (the flow below which water withdrawals for offstream uses are not permitted) for streams in a relatively hydrologically homogeneous region,...

Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...

Canal Discharge Impacts on Fahka Union Bay
The effect of a large drainage canal's discharge on Fahka Union Bay's value as a nursery ground for estuarine-dependent fish and shellfish, including commercially...

Real-Time Monitoring for Ohio Basin Water Management
The Ohio River Division (ORD) of the Corps of Engineers operates 77 reservoirs in this basin for the purposes of flood control, conservation, hydropower, low flow augmentation, water supply,...

Numerical Modelling of Pollutant Transport from a Pond to a Stream
The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water...

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...

South Branch Rockaway Flood Water Study
The paper reports on a study to analyze in detail various methods of storm water management. The technical studies were carried out in an actual watershed setting to arrive at a recommended...

Control of Select Priority Pollutants in Stormwater
A simulation program to generate the runoff quantity and quality for each storm event over a 5 year period was written. Chemical loading rate data from highways was used. Runoff was considered...

Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...

Simulation of Wetland Hydrology and Hydrodynamics
The relative changes in water stage in swamps and marshes and the variations of current velocities in bayous and canals under present conditions are calculated, using a computer watershed...
