Quantifying Mud Exchange Between the Eastern Scheldt Tidal Basin and the North Sea
Net transport of sediment < 53 ?m through the mouth of the Eastern Scheldt has been quantified. Combination of data on spatial and temporal variability shows that incertainties...
Effect of Varying Sediment Size on Equilibrium Beach Profiles
Beach profiles from four field sites and accompanying data describing the cross-shore distribution of median sediment size are analyzed and compared to predicted profiles based on an equilibrium...
The Sedimentary Organisation and Behaviour of Drift-Aligned Gravel Barriers
Drift-aligned barriers formed of coarse clastic materials and described in terms of their organisational evolution at two levels, a) sorting and selection of clasts; b) development of...
Sorting Characteristics of Tidal Inlets
An hypothesis is presented as follows: Littoral processes at a tidal inlet remove a disproportionately higher quantity of fine grain sediment than coarse grain sediment from the littoral...
Mound Migration in Deeper Water and Methods of Categorizing Active and Stable Depths
Sustained shoreward migration of several dredged material disposal mounds, including one in 6-m depths off the Alabama coast, should encourage greater use of nearshore placement to conserve...
Complex Principal Component Analysis of Wave-Like Sand Motions
Complex Principal Component Analysis is applied to bathymetric data from the SUPERDUCK experiment at Duck, NC. This approach is shown to describe more of the variation with fewer functions...
Information Entropy and Environmental Engineering
Environmental engineering decisions are often made with limited information. In such cases it is useful to express uncertain quantities with a probability distribution. The use of information...
Concrete Gravity Dam Cracking Analysis Methodology
This paper describes a methodology for the prediction and evaluation of cracking behavior in concrete gravity dam's for use in periodic safety investigations as outlined in...
Three Dimensional Modeling of Concrete Dams with Cracks Using Boundary Element Methods
Determining uplift pressure distributions in cracks in a concrete dam requires coupling between crack hydraulics and the stresses and displacements occurring in the rock and the concrete...
Physical Hydraulic Modeling for Construction of New York State Dam Hydroelectric Project
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into four main channels as the water...
Some Unusual Vibrations in Hydro Machinery
Most hydro machinery engineers have read the textbook cases of self-exited and flow induced vibrations. Usually such textbook vibrations are only found in the text book! In the real world,...
A New Method for Calculating a Mathematical Expression for Streamflow Recession
An empirical method has been devised to calculate the master recession curve, which is a mathematical expression for streamflow recession during times of negligible direct runoff. The...
Slug Test: Double-Porosity, Linear Boundary, and Variable Storage Effects
The intention of this paper is to focus on three aspects of the slug test that are not as familiar as the main analysis techniques: the effects of double-porosity formations, the effects...
Three-Dimensional Velocity Distribution at Open-Channel Diversions
A study is underway to develop an improved understanding of the 3-D flow pattern at 90? diversions. The main goal is to explain, via the velocity distribution, the behavior of sediment...
Temperature Rise, Bank Erosion, and Jet Velocity Effects of Submerged Multiport Diffusers in an Estuary
Temperature distributions, potential bank erosion, and jet velocity and trajectory of submerged multiport diffusers were predicted as part of the permitting process for an fossil fuel...
Design of a Stratified Cooling Channel
Cooling ponds are used for managing waste heat discharges. Cooling ponds are, however, expensive to construct and operate. A cooling channel is studied as an alternative means of managing...
Modelling Longitudinal Temperature Distribution in TVA Reservoir System
A one-dimensional model has been developed for computation of water temperature in the TVA reservoir system. The model has been successfully used in evaluating the impact of incremental...
Spatially Varying Velocity Distribution in Non-uniform Open Channel Flow
The spatial variation of velocity distribution in non-uniform flows were studied, within the framework of a velocity distribution model derived by a probabilistic formulation and entropy-maximization....
Chesapeake Bay Data Set for Three-Dimensional Hydrodynamic Model Verification
A comprehensive data set representing September 1983 conditions on the Chesapeake Bay has been assembled and is proposed as a possible data set for inclusion in the work of the ASCE Task...
The Dilemma of Measuring Small Pressure Changes in a Settling Tube
A compact settling tube was developed to determine fall-velocity and particle-size frequency distributions and specific gravities of sand-range sediment samples by means of direct measurements...
