Floodflow Effects on Riparian Vegetation in Arizona
A relation for estimating changes in the condition of riparian vegetation as a function of stream power was developed for stream channels in central Arizona. Flood and vegetation data...
Bias in Regression Estimates of Manning's n
Selected equations for estimating roughness for gravel-bed streams were tested using a composite data set containing much of the data used to define the equations. All equations tested...
Analysis of Levee Design in a Mountain River Using Two-Dimensional Flow Modeling
The South Branch of the Potomac River experienced extreme flooding in November 1985. A flood with an estimated return period of 400 years caused $33 million in damage in Petersburg, West...
Boundary Conditions and Flow Patterns in a Mountain River
Flood flow patterns in mountain valleys may be influenced by longitudinal variations in channel and valley morphology and by temporal variations in boundary conditions. This study utilizes...
Erosion and Deposition by Debris Flows in Mountainous Channels on North Fork Mountain, Eastern West Virginia
A study of four debris-flow impacted channels in the North Fork Mountain area of eastern West Virginia shows that the geomorphic effect of debris flows on channel morphology is variable...
Palaeohydraulic reconstruction of floods in upland UK bedrock streams: progress, problems and prospects
Palaeoflood evidence from five small upland Pennine catchments in the UK is used with the HEC-2 flow routine to simulate Holocene peak discharges. Even allowing for uncertainty, sensitivity...
Streamflow Related to Channel Geometry in Northern New England
Channel geometry measurements can be used to estimate various streamflow characteristics at ungaged stream locations. Channel cross section dimensions and sediment size distributions were...
Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...
Historic-Flood Evaluation and Research Needs in Mountainous Areas
An evaluation of historic flood estimates in mountainous areas in Colorado was made to assess their accuracy. The purpose of this evaluation is to enhance awareness of the need to assess...
Determination of Sediment Profile for a Dry Flood Control Basin
A modification of the standard delta profile method was used to estimate the sediment profile in a dry flood control basin. Dry flood control basins do not have a normal operating pool...
Evaluation of Six Methods for the LP3 Distribution
Six frequently used estimation methods for the Log-Pearson type 3 distribution were evaluated using both the predictive and the descriptive performance indices. Ten LP3 populations and...
Discharge-Frequency Relationships in Distributary Flow Systems
The paper describes discharge-frequency relationships in distributary flow systems. The stream network that makes up the flow system is described in terms of how the various stream segments...
Comparison of Infiltration Equations Using Flooding Infiltrometer Data
Based on three flooding infiltrometer tests, 27 hydrographs produced by HEC-1 were used to compare peak discharge, time to peak, and storm runoff volume using three infiltration functions....
Problems of Stream Flood Simulation and Prediction
The article presents a report on the natural flooding in a stream and the problems encountered when simulating and predicting stream floods. The complexity of flood characteristics, the...
Hocking River Sedimentation Study
The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However,...

DSM Saves the Dam
The Miami Conservancy District built five flood control dams after the catastrophic flood of 1913 in Dayton, Ohio. Lockington Dam was one of these five hydraulic fill structures. The Ohio...
Route 5: Steel Fibre Shotcreting in Shing Mun Tunnels Hong Kong?Specifying for Innovation
The Shing Mun tunnels form the central 2.6 km length of the Route 5 Highway connecting Tsuen Wan and Sha Tin New Towns, Hong Kong. The crossing of one of the areas was particularly difficult,...
Scoping Out Scour
Bridge scour�soil erosion around piers and pilings�threatens tens of thousands of bridges across the U.S. Traditionally, engineers have mapped bridge scour by driving probes into the subbottom...
Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...
