Numerical Model Development for Oil Spill Dispersion into the Marine Environment
A 3-D oil spill model was developed to study the behaviour of heavy spilled oil in the sea. The model could describe the behaviour on the spilled oil on the sea surface, throughout the...
A New Approach to Local Scour Depth Estimation Under a Horizontal Jet or Free Water Fall
A new formula is presented to estimate the local scour depth development with time due to a horizontal jet or free water fall based on a new approach which combines the concept of energy...
TransAct: An Interactive Transient Analysis Program for Pipelines
The program TransAct is designed to analyze a wide range of transient responses that may have been caused by a complex combination of control actions. For example, there may be the simultaneous...
Predicted Fluvial Response to Dam Removal in the Kalamazoo River Valley, Michigan
Research has been conducted by the Michigan Department of Natural Resources (MDNR) to predict the fluvial response to dam drawdown and determine the distribution of recent deposits along...
Measurement of Air Entrained Flow Properties
The paper discusses conventional methods used in the field to measure bubble size, air concentration, intermittency, and velocity of air entrained flows in chutes....
3-D Hydrodynamic Model Verification Using ADCPS
A physically comprehensive, hydrodynamic model of the East River has been used for a continuous three year simulation. As part of the calibration process, detailed vertical profiles of...
Enhancing Effluent Water Quality of Sedimentation Basins Using Constructed Wetlands Technology
The Tennessee Valley Authority (TVA) has constructed twelve wetlands to treat acid drainage at reclaimed coal mines and fossil-fueled power plants. These wetlands are designed primarily...
Comparison of a Vibrational Gage and a Plummet for Continuously Measuring Fluvial-Sediment Concentrations
Obtaining sediment records for small, remote streams is difficult not only because of the logistical problems, but also because of the rapid changes in concentration that accompany the...
Data Acquisition Techniques for Rotating Machinery
Monitoring the condition and performance of a hydraulic turbine or pump requires the simultaneous collection of data related to shaft speed, torque, power, water and airborne sound pressure...
Model Studies of Outlet and Intake at McCook Reservoir
Two separate physical models were used to investigate the outflow and inflow into the proposed McCook Reservoir. The proposed reservoir will be located in McCook, Illinois, and will serve...
Vortex at Hydraulic Intakes with Asymmetric Approach Flows
The formation of vortices at intakes can disrupt normal operating procedures and damage hydraulic machinery. Asymmetric approach flow and a protruding pier (normal wall) contribute to...
Improved Intake Design for Downstream Migrating Fish at Hydropower Plants
Fish guidance efficiency of screens is a function of the submergence of a hydropower intake. The submergence of an intake can be reduced through the use of intake extensions or guides...
Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...
McClure Park: A Multi-Purpose Off-Stream Storage Facility for Tulsa, Oklahoma
The City of Tulsa is in the process of implementing a flood control plan for the 61 square-mile (158 km2) Mingo Creek watershed. The federally-assisted...
Gropps Lake Dam
Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel...
Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...
Data Acquisition for Hydrologic GIS
Various data acquisition options for hydrologic oriented GIS are presented. These options include manual digitizing, commercial digital data, satellite products, and automated scanning....
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
Geographic Information Systems in Water Resources Management
The management of surface and ground water resources within Southern California is increasingly difficult. As population expands, municipal demands for water are increasing. At the same...
Return Velocities Induced by Shallow-Draft Navigation
Return velocities are caused by the displacement effects of vessels as they travel in navigation channels. Numerous return velocity equations have been developed for relatively small channels...
