Probability Based Evaluation of Spillway Capacity
Spillway adequacy could be evaluated more objectively if estimates were available of the probabilities of discharges up to the Probable Maximum Flood (PMF). As a first step in making such...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Verifications and Applications of a Nonpoint Source Pollution Model
To meet the needs of the Illinois Comprehensive Monitoring and Evaluation (CM&E) project of the Rural Clean Water Program (RCWP), the Agricultural Nonpoint Source Pollution Model...

Legal Misuse of Urban Hydrology Concepts and Regulations for Rural Areas
This paper presents recent observations of the misuse of technical definition, hydrologic concepts, sedimentation engineering principles, and flood control regulations by the legal profession...

Optimization of Complex Hydrologic Models Using Random Search Methods
The primary objective of automated calibration of complex conceptual hydrologic simulation models is to find the global optimum of a specified response surface. While direct search techniques...

A New Method for Synthesizing a Six Hour Unit Hydrograph
A new methodology was devised that would use readily available basin physical parameters for the determination of unit graphs in undeveloped and ungaged areas. Rather than using small...

Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...

Simulation Algorithms for Offshore Structures
A rational procedure for characterization of water depths for a random sea state is developed, in context with linearized wave theory. The importance of using the expressions for 'intermediate...

Environmental Engineering
The American Society of Civil Engineers annually sponsors a Specialty Conference on Environmental Engineering. The 1987 Conference was held in Orlando, Florida on July 7-9, 1987 with cooperation...

Coastal Hydrodynamics
This book includes papers presented at the ASCE Specialty Conference on Coastal Hydrodynamics Conference, at the University of Delaware, June 28-July 1, 1987. The papers review the state...

Rescuing the Everglades
After a century of trying to control Florida's Everglades, water management officials have decided that cooperating with nature is better. A new strategy known as the Rainfall...

Cleanup on a Large Scale
The San Gabriel Basin yields 200,000 ac ft of groundwater a year from 400 supply wells. This water makes up 95% of the Valley's water supply. Already 30% of the water pumped...

Fishing the Four-Lane
Recent changes in one Montana canyon have shown that even highways and freshwater fish can happily coexist with the proper planning. Twenty years ago, the Montana Department of Highways...

Treating Expansive Soils
Damage that expansive soils do to light buildings can often be prevented or mitigated by preconstruction soil treatment. Treatments of three kinds are described�reworking the soil, controlling...

Modeling Permissive Movements in TRANSYT-7F
Traffic Network Study Tool (TRANSYT-7F) is one of the most widely used traffic flow analysis and traffic signal timing optimization models in the United States and elsewhere. Through 'Release...

Conversion of the MIDAS Accident Analysis Model
The MIDAS (Michigan Dimensional Accident Surveillance) System has been developed to provide accident analysis capability. A microcomputer version of MIDAS is being developed to make the...

Teacher Friendly Transportation Programs
This contribution describes a set of computer programs that has mainly been developed to demonstrate operating and possibilities of mainframe programs during lectures. The program set...

Expert Systems for Traffic Signal Control
The level of service achieved by a pretimed signal timing control strategy implemented at an isolated intersection incurring saturated and over-saturated demand varies with actual traffic...

Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering, August, 1987, Williamsburg, Va. The objective of this conference was to provide a forum...
