Rainfall Intensity-Duration Equations
A method for rapidly developing a rainfall intensity-duration equation for durations less than one hour and recurrence intervals between 2 and 100 years for any location in the conterminous...
Hydroturbine Efficiency and Cavitation Monitoring
The paper describes a microcomputer-based system for monitoring hydroturbine performance and cavitation level. Remote access to the monitoring system provides convenient, rapid, and accurate...
Entropy as a Probability Concept in Energy-Gradient Distribution
The concept of entropy based on probability theory instead of thermodynamic principle has been applied to study the distribution of energy gradient along alluvial rivers. The formulas...
Longitudinal Dispersion in Rivers: A Dead Zone Model Solution
The longitudinal dispersion of tracer material in rivers is often analyzed based on the one-dimensional convective diffusion equation developed by G.I. Taylor. However, the persistent...
Design of Riprapped Scour Holes for Flip Bucket and Overfall Spillways
Presented in this paper is a simple method of predicting pre-excavated scour depths and geometry for riprapped basins below flip bucket spillways. The input data needed for establishing...

The results of the ASCE Hydraulics Division Task Committee on Reliability Analysis of Water Distribution Systems are summarized in a very comprehensive report entitled Reliability Analysis...
Robotics Research for Construction in Space
Research in construction robotics, terrestrial or otherwise, has focused on issues which are broadly pertinent to space applications. Construction robotics, as addressed by this writer,...
Lessons from Dam Incidents. US-II
The purpose of this report is to present available data to the profession regarding failures, accidents, and major repairs at dams in the United States. Data is analyzed with respect to...
Highway Safety in 2010: Compromising Among Values
A prediction is made of the highway safety development, based on analysis of current crash data and expected improvements in highway safety. The paper includes discussions of travel mileage...
Benefits of Highway Safety Improvement Programs
Even at the most conservative estimate of 2% annual growth in travel, the U.S. would experience almost 58,000 deaths in the year 2000 at a death rate of 2.5 per 100 million miles traveled....
Long Distance Dam Data
Remote data collection systems are increasingly being used for dams. Instrumentation of structures for obtaining data on performance is not new. However, automation and computerization...
Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Inexpensive Geo-Coding for Water Utilities
Geo-Coding enables Hackensack Water Company to optimize meter reading and customer service routing; to analyze water consumption data at a micro level, and relate that data to census and...
Earthquake Response of La Villita Dam
Due to the recent industrial and housing developments at the port of Lazaro Cardenas, located 13 km (8 miles) downstream of La Villita Dam, at the mouth of the Balsas River, the hazard...
Technical Issues of Ground Water Data
Three fundamental issues to be considered in the design of ground water monitoring programs are 1) choice of parameters for characterizing contaminant sources, 2) determining the areal...
