Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...

Tiebacks for Bulkheads
Tiebacks were once used primarily to support temporary structures such as supported excavations. However, the use of tiebacks has been gradually expanded to include the support of permanent...

Forensic Engineering
Learning from Failures
The activities and qualifications of the Forensic Engineer are summarized in the nine papers published in this book. Procedures for failure investigation are discussed along with failure...

CAD Goes into Analysis
In the past, computer analysis of a design was always a separate and distinct step from CAD. Now, an increasing number of systems are combining the two. One system, SSCAD, allows the engineer...

Interpretation of CPT Data for Design of Earth Dams Near Tehachapi, California
The Static Cone Penetration Test (CPT) was used to obtain needed geotechnical information for design and construction of two small earth dams near Tehachapi, California. The basic CPT...

Comparison Between In-Situ Test Results
Penetration tests provide a means of obtaining data from which estimations can be made of the bearing capacity, settlement and liquefaction potential of the soils tested. Empirical formulae...

Co-ordinated Microcomputer-Based Rain Data Network and Modeling Environment
A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor...

Linking Data Base Management and Computer Models
Storing, tabulating, and graphing large volumes of data, not usually a strong point of a computer model, is more appropriate for a data base management system. A blend of these two technologies,...

A Customized Database Management System for Watershed Modeling
When large watershed areas are being studied and continuously monitored, it is desirable to create a database management system (DBMS) that provides the necessary capability to build and...

The Rx for Relief from Equipment Failure
A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data...

Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...

Corps of Engineers Automation of Real-Time Water Control Management
Automation of real-time water control management activities has enabled the Corps to keep pace with an ever increasing workload in a time of fiscal constraint and reduced manpower. Where...

Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...

Characteristics of Intense Storms in Kansas
This paper examines point-rainfall characteristics of intense storms in Kansas. Hourly rainfall records were analyzed for 1006 intense storms selected from some 1800 station-years of data....

Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...

Heppner's User-Friendly Local Flood Warning System
The Heppner, Oregon, local flood warning system uses state-of-the-art technology with event-initiated data transmission, real-time monitoring, and automatic evaluation and notification....

Geohydrologic Considerations in Ground Water Modeling
Ground water modeling is an effective engineering and management tool for evaluating complex hydrogeologic situations in a cost effective manner. Objectives of a particular study dictate...

Water Issues in Tropical and Sub-Tropical Australia
The Northern Territory and State of Queensland cover an area of 3. 1 million km**2 and encompass most of the tropical and sub-tropical zones of Australia. Surface and groundwater resources...

Geotechnical Construction Control Data Base Package
A data base can be defined as pieces or groups of data stored together in an orderly form such that access to all or any part of the data can be readily accomplished. A computerized data...

Production Analysis of the Cat 245 Hydraulic Hoe
The productivity of two Caterpillar model 245 hydraulic backhoe excavators was analyzed during their use on a highway construction project in September 1983. The hoes were working in a...
