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...
Estimating Low-Flow Frequencies of Ungaged Streams in New England
Equations to estimate low flows were developed using multiple-regression analysis with a sample of 48 river basins, which were selected from the U. S. Geological Survey's...
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....
Some New Snyder Type Coefficients for Small Watersheds
Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq...
Changing Hydrology - The Middle Mississippi River
Observed daily flow and stage at major stream gages on the middle Mississippi River are numerically and graphically analyzed to quantify and illustrate the magnitude and seasonality of...
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...
Measuring the Spatial Characteristics of Unsteady Pressures
This paper has reviewed current methods of determining spatially-averaged time-varying wind loads on wind tunnel building models. Some of the possibilities opened by simultaneous multi-channel...
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...
A Burning Wasteland Reclaimed
Until recently the PJP Landfill exemplified what can happen when uncontrolled and illegal dumping goes on for many years. Now it is an example of what innovation and imagination can do...
Considerations in Applying the 1985 HCM Procedures
The paper examines the impact of critical assumptions in the 1985 Highway Capacity Manual (HCM) procedures on the resulting measures of effectiveness -- volume/capacity ratio, delay, and...
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...
