Off-Site Water Quality or On-Site Productivity
Nonpoint sources of pollution are being recognized as the primary source of water quality degradation in many coastal areas. In those areas where management programs are being implemented,...

A Study of Selected Environmental Parameters of Small Coastal Lagoons as a Function of Extent of Urban Development, Hydraulics of the Tidal Inlet, and Hydrology of the Contributing Drainage Area
In coastal areas many small brackish water lagoons or embayments connected to the sea by small tidal inlets are at tractive to residential and commercial developers, especially those emphasizing...

Federal Policies in Water Resources Planning
The adequacy of current federal policies and institutional arrangements for water resources planning is assessed. Conclusions and recommendations are presented in five key areas: (1) Water...

Watershed Management in the Eighties
The papers included in this publication discuss state-of-the-art methods and current research on management and present case studies on current projects and practices on applied watershed...

Coping with Litigation
Engineers should learn legal philosophy, even though it seems unrelated to traditional technical practice. Monitoring changes in legal theory that may increase engineers'...

Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...

Project Mixes Oil and Water
The Prudhoe Bay Seawater Treatment Plant was nominated for an OCEA award, for its potential to coax from Alaska's north slope 1 billion barrels of oil which otherwise would...

Sewer Construction Inspection and Testing
Sewer construction testing is the final portion of the team effort that started with the goal of meeting the requirement for a sewer system for the protection of health and environment....

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...
