Engineering, Construction, and Operations in Space II
This proceedings, Engineering, Construction and Operations in Space II, consists of the 165 papers presented at Space 90, the Second International...

Competition for Water in Southern Nevada - Local Needs Versus Federal Control
The impacts of lands in southern Nevada, withdrawn by the federal government for defense and defense-related purposes on the water supply, are discussed. Nevada is an illustration of an...

Drainage Manual for Clark County, Nevada
The development of a flood control district and its associated capital improvement and regulatory programs does not by itself address drainage standards for a community. While the capital...

Regional Flood Frequency Equations for Antelope Valley in Kern County, California
Rapid residential, commercial, and industrial development has occurred in recent years in the Antelope Valley, California. With the new development progressing at full speed, the local...

Precipitation on Arid or Semi-Arid Regions of the Southwestern United States: Research Needs from a Consultant's Perspective
In terms of both instantaneous flow peaks and total runoff volumes, a key element in the quantification of stormwater runoff from arid and semi-arid regions of the southwestern United...

The Sorry State of Flood Hydrology in the Arid Southwest
Flood hydrology for urban areas of the arid and semiarid Southwest is in a sorry state. It is based in large part on precomputer manual methods. The state-of-the-art should move into the...

Way Against Debris Flows at China's Mountain Towns
For important protected objectives, the measures against debris flow in mountain towns should ensure all-round reliability and adopt a comprehensive system of engineering projects combined...

A Value Engineering/Risk Analysis Approach to Operation and Maintenance of Hydraulic Structures
Value engineering is an objective, systematic method for minimizing cost of a system. Risk analysis is a method of quantifying uncertainties or probabilities of possible economic loss,...

Flood Control Improvements on Alluvial Fans
Floodplain management on alluvial fans has become an increasingly important issue with continued growth and urbanization in the southwest. The design of flood control facilities for new...

GIS: Easing Infrastructure Management
GIS provides an ideal means for city planners and engineers to plan construction and maintenance of water-distribution networks, wastewater-collection systems and treatment plants, highways,...

Field and Model Studies of Ocean Outfalls
Field and laboratory studies of the behavior of wastewater discharged from the San Francisco ocean outfall are reported. Wastefield behavior was predicted by the mathematical models RSB...

Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment
The Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment was formed on October 1, 1989 under the Technical Committee on Hydrologic Transport and Dispersion...

Identification Techniques for Bank Erosion and Failure Processes
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has developed techniques to design small flood-control channels. A component of this research is the...

Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...

Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...

The Sediment Weighted Histogram Generator and Estimation of Sediment Transport Trends
Long term sediment transport trends may be evaluated using a sediment histogram generator program that was written for microcomputers. Flows can be extracted directly from a compact disc...

Status and New Capabilities of Computer Program HEC-6: Scour and Deposition in Rivers and Reservoirs
Last year the Hydrologic Engineering Center (HEC) and the Waterways Experiment Center (WES) incorporated the results from more than ten years of research and development into a new version...

Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...

Urban Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair an all too familiar problem of cattails growing in the...

Pressure and Stress Distributions Due to a Submerged Impinging Jet
This investigation examines the pressure and shear stress distribution at a smooth planar boundary in the impingement region of a submerged vertical jet in water. The mean pressure and...
