Differentiation of Debris-Flow and Flash-Flood Deposits: Implications for Paleoflood Investigations
Debris flows and flash floods are common geomorphic processes in the Colorado Rocky Mountain Front Range and foothills. Usually, debris flows and flash floods are associated with excess...
Importance of Hydraulic-Model Uncertainty in Flood-Stage Estimation
The delineation of the regulatory floodplain and determination of the respective flood stage is subject to hydraulic-model uncertainty in transforming the design discharge into a flood...
Progressive Failure of an Overtopped Embankment
The failure of an overtopped embankment is a problem of a very complicated nature. Concerned organizations are interested in information that can be used in future planning and development...
Assessing the True Value of Flood Control Reservoirs: The Experience of Folsom Dam in the February 1986 Flood
Over the last 40 years considerable public investments have been made in large flood control storage reservoirs throughout the U.S. and internationally. These projects were typically designed...
Integrated Planning Analysis for an Aggregate Mine
Planning and design work of an aggregate mining facility within the Sutter Bypass, a key component of California's flood control system, is being performed by multidisciplinary team of...
Using Geophysical Data to Assess Scour Development
The development of scour holes in the Connecticut River near the new Baldwin Bridge has been documented by comparing geophysical records collected before (1989), during (1990), and after...
Reliability Analysis of Levee System of a River
The levee height is determined by the summation between computed water level and an assumed freeboard. The water level is computed by given discharge in the steady conditions. Therefore,...
Risk and Uncertainty in Flood Damage Reduction Project Design
The recent emphasis on partnership between the Federal government and local sponsors in the development of flood damage reduction projects has promoted considerable interest in the application...
Selective Withdrawal for Reducing Turbid Water in a Reservoir
This paper deals with improvemental operations of the selective withdrawal facilities as one of the comprehensive technics for shortening the turbid water stay after floods flown into...
Bridge Scour Evaluations in Washington State
Eighteen existing bridges were investigated for Washington State DOT as part of the FHWA National Scour Evaluation Program. Investigations included review of file information, site inspection,...
Probability and Impact of an Observed Rare Sequence of Floods
Accordingly, it may be concluded that the severity of the recorded sequence would be exceeded in about 2.1 percent of future sequences, or have about one chance in 45 or 50 of being exceeded...
Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
Honolulu International Airport (HIA) APM
The Hawaii Department of Transportation, in planning to meet passenger demands over the next 20 years, is providing for expanded terminal buildings. The expanse of the airport requires...
American Airlines' TrAAm System Vehicle Modification/Conversion Program
In October of 1992 American Airlines inaugurated a new people mover service among four stations within its two-terminal complex at the Dallas/Fort Worth Airport (D/FW). Named the `TrAAm,'...
Dams Going Safely over the Top
Many older dams can't pass updated design floods without overtopping the embankment crest. Conventional upgrade methods, enlarging spillways or raising crests, are expensive....
The Talbert Channel Ocean Outlet Project
The Talbert Channel Ocean Outlet Project consisted of relocating and enlarging the outlet of a relatively narrow, shallow flood control channel in Southern California. Noteworthy aspects...
Construction on Wisconsin's Lake Michigan Coast
This paper provides a preliminary evaluation of a set of 100 residential properties along Wisconsin's Lake Michigan coast; an examination of the vulnerability of coastal homes and adequacy...
Evaluating Spillway Adequacy
More than a third of all dam failures are caused by overtopping. Equipment malfunctions or operations errors are sometimes to blame, but the principal cause is inadequate spillway capacity....
Urban Development on Alluvial Fans
An increasing number of developments has been planned in areas subject to flood hazards. To protect developments from flood damage and to prevent accumulated negative effects on floodplains,...
