Variation of Froude Number with Discharge for Large-Gradient Streams
Under chemical-control conditions, the Froude number (f) for a cross-section can be approximated as a function of the ratio R2/ 3/d...

Predicting Critical Scour Stage at Bridges
After an initial level I screening process, most level II bridge scour studies result in recommendations for costly scour countermeasures. Typically, existing transportation budgets cannot...

Modeling Critical Depth in Open Channels
This paper explores multiple critical depths. Reasons behind and characteristics of their occurrence are reviewed. A method to determine multiple critical depths is proposed for use in...

Roll Waves in Mud Flow
Permanent roll waves on a shallow layer of fluid mud which is modeled as a power-law fluid is studied. Based on long-wave approximation, momentum integral method is applied to derive the...

Sediment Deposition in Jennings Randolph Reservoir, Maryland and West Virginia
The watershed of the Jennings Randolph Reservoir covers 263 square miles of mountainous terrain in western Maryland and West Virginia. Sedimentation studies performed prior to impoundment...

Hydraulic Model Studies of Y-Branch
Hydraulic model studies were made for the Y-branch steel penstock located in a vertical bend. The model tests were performed for various modes of pumping and generating operation. The...

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 Water-Surface Profile (WSPRO) Model
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...

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...

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...

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...

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...

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...

Parameterization of Turbulence for Three-Dimensional Circulation Modeling
Estuarine circulation are driven by the actions of tide, wind, and density gradients associated with saline ocean water and fresh riverine water, and are also influenced by the complex...

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...

Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...

Ballast Water Treatment Effluent Dispersion Studies
Treated tanker ballast water is discharged form Alyeska Pipeline Service Company's ballast water treatment facility through a multiport diffuser into Port Valdez, Alaska. The discharge...
