Acoustic Doppler Current Profiler for Inlet Current Measurements
A BroadBand Acoustic Doppler Current Profiler (BroadBand ADCP) was used to survey tidal currents at Shinnecock and Moriches Inlets, Long Island, NY. Measurements were made remotely form...
Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...
Confirmation of Seismic Safety at Stafford Dam
A critical aspect of the North Marin Water District's mission to maintain reliable water supply facilities and water service is periodic assessment and re-evaluation of the seismic safety...
Bridge-Scour Analysis Using the
A program was developed to extract hydraulic information required for bridge-scour computations, from the Water-Surface Profile computation model (WSPRO). The program is written in compiled...
Debris Flow Initiation and Termination in a Gully
A comprehensive simulation model predicting the debris-flow discharge hydrograph, solids concentration in it and the process of variation of the channel due to vertical as well as lateral...
An Empirical Model for the Volume-Change Behavior of Debris Flows
The potential travel down hillsides; movement stops where the volume-change behavior of flows as they travel down hillsides ; movement stops where the volume of actively flowing debris...
Mapping Debris-Flow Hazard in Honolulu Using a DEM
A method for mapping hazard posed by debris flows has been developed and applied to an area near Honolulu, Hawaii. The method uses studies of past debris flows to characterize sites of...
Prediction of Occurrence and Runoff Analysis of Debris Flow
A debris flow will occur on a slope when the rainfall exceeds a certain value determined by the hydraulic, geological and topographic properties of the slope. To estimate this critical...
Sediment Deposition from Debris Flow on a Gentle and Wide Slope
Motion of sediment grains in the deposition process from debris flow on a gentle and wide slope was examined. A model of the deposition was presented on the basis of an analysis of grain...
Quantity and Quality of Dry Weather Flow in Las Vegas Valley, Nevada
In recognition of the potential for dry weather flows to convey pollutants from the Las Vegas Valley, the potential economic and resource value of these flows within the Valley, and the...
Protected Streamflow and Water Uses
The development of protected-streamflow standards is essential for the most desirable and equitable use of stream waters for aquatic habitats, municipal and industrial water supply, and...
Application of Environmental Regulations on Design of Hydraulic Structures for Open Cooling Water System
Design of intake and discharge structures for an open cooling water system for a thermal power plant requires that the design of hydraulic structures meets the federal, state, and local...
The Concept of Local Euler Number as an Aid for Sizing Pitot Tubes
Correlations with drag coefficients enable determining the relations between the form of Pitot tubes and their velocity coefficients. A numerical example is presented to clear the use...
Methods for Prediction of Maximum Scour at Coastal Structures
The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction...
Estimating Bridge Scour in New York from Historical U.S. Geological Survey Streamflow Measurements
Historical streamflow measurements by the U.S. Geological Survey an bridge-inspection reports by the New York State Department of Transportation are being used to estimate scour at 31...
Relation of Local Scour to Hydraulic Properties at Selected Bridges in New York
Hydraulic properties, bridge geometry, and basin characteristics at 31 bridges in New York are being investigated to identify factors that affect local scour. Streambed elevations measured...
Scour Inspection Using Ground Penetrating Radar
This paper examines the capabilities of Ground Penetrating Radar (GPR) for river bed scour inspection based on a study carried out by Clarkson University, Potsdam, New York in association...
Debris Flow & Hyperconcentrated Flow: A UK Perspective
Debris-flow activity within the UK is largely confined to upland regions and certain coastal locations. Within the uplands, debris-flow and hyperconcentrated flood waters pose a local...
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...
Time-Dependent Landslide Probability Mapping
Case studies where time of failure is known for rainfall-triggered debris flows can be used to estimate the parameters of a hazard model in which the probability of failure is a function...
