Depleted Uranium Migration in Stream Bedload Environment
The objective of this paper is to present results of a comprehensive hydrologic transport study, designed to assess potential surface water contamination, resulting from the release of...

Versatile Methodology for Flow Depth and Velocity Modeling in Stream Aquatic Habitat Assessment
The habitat assessment methodology developed by the IFG Instream Flow Group is a useful tool for evaluating instream flow needs. The methodology for basin flow modeling developed in this...

Infiltration as a Dependent Variable in Modeling Furrow Irrigation
Most surface irrigation models assume that infiltration is independent of surface flow hydraulics. However, wetted perimeter has been shown to significantly affect infiltration in furrows....

A Linked Stream-Aquifer System Model
A linked stream-aquifer system (LISAS) model is described. This model includes a deterministic sequential flow simulation component which generates hydrographs of surface runoff and deep...

Kinematic, Diffusion and Dynamic Catchment Modeling
This paper reports on a series of tests aimed at developing improved procedures for catchment routing. The objective is to compare kinematic and diffusion models within several scenarios...

A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...

Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...

Time of Concentration in Small Rural Watersheds
A comparison was performed between the exponents of the independent variables L, S and i of the four-parameter time of concentration equation and eleven frequently encountered equations....

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Fault Identification by Seismic Impact Load Techniques
The propagation of seismic waves generated by impact loading across a normal fault in carbonate rock was investigated by the seismic refraction technique. The field records were reduced,...

Simulation Algorithms for Offshore Structures
A rational procedure for characterization of water depths for a random sea state is developed, in context with linearized wave theory. The importance of using the expressions for 'intermediate...

Coastal Hydrodynamics
This book includes papers presented at the ASCE Specialty Conference on Coastal Hydrodynamics Conference, at the University of Delaware, June 28-July 1, 1987. The papers review the state...

Harbor Revived
In Racine, Wis., officials' plans to turn a defunct commercial harbor into a recreational boaters' paradise have signaled an economic turn-around for a depressed...

Experiences in Pneumatic Wave Energy Conversion in Japan
Several prototype and model studies of pneumatic wave energy conversion systems are discussed. These include those of the floating platform KAIMEI, the fixed system at Sanze and the new...

Prototype Wave Power Stations in Norway
The KVAENER multi resonant oscillating wave column (MOWC) power station is both described and discussed. The power station, which is now on-line, is designed to produce 1 MW of peak electrical...

Operational Experiences With a Wells Turbine on a Wave Powered Navigation Study
The objective of the research programme was to design a 100W Wells turbine generator unit which could be matched to standard tail tube buoys. Optimization of the power conversion chain...

A Comparative Study of Two Capture Chamber Geometries
Results of an experimental study of two capture chambers are presented. The capture chamber geometries are those that have been either used or recommended in conjunction with pneumatic...

Studies With, and Testing of the McCormick Pneumatic Wave Energy Turbine With Some Comments on PWECS Systems
Work done in developing concepts for pneumatic wave energy conversion based on theoretical analyses of the hydrodynamic, pneumatic, and mechanical systems with some estimates of performance...

Converted Wave Energy Transmission, Storage and Integration
Results of a number of full-scale studies of transmission, storage and integration of electricity resulting from wave energy conversion are discussed. These studies involved the floating...

Preliminary Design and Construction Plan for an Ocean Wave Energy Conversion System
