Using the Weir Back as an Energy Dissipator
The effect of weir back in energy dissipation is investigated experimentally and theoretically. The study includes four different shapes of weir back. The boundary friction force and the...
Depth-Averaged Flow Model in Curvilinear Coordinates
Implementation of a depth-averaged model in orthogonal curvilinear coordinates permits to resolve questions about grid refinement, the representation of complicated boundaries, and the...
Boundary Conditions and Flow Patterns in a Mountain River
Flood flow patterns in mountain valleys may be influenced by longitudinal variations in channel and valley morphology and by temporal variations in boundary conditions. This study utilizes...
A General Theory of Channel Adjustment in High Gradient Streams
The paper presents a theory of channel adjustment in high gradient streams. This theory states that given sufficient energy, stream channels will adjust their dimensions and flow hydraulics...
Air Entrainment and Bubble Behavior in Plunge Pools
This study analyzes air entrainment by falling nappes and bubble behavior in plunge pools, using an experimental-analytical-numerical method. The experimental work was done at the Tennessee...
Investigation of an Anisotropic k-ε Model
In this paper the eddy viscosity hypothesis is abandoned and explicit expressions of Reynolds stress are deduced directly from the transport equations. Anisotropic k and ɜ equations are...

Kinematics of Wave Overtopping on Marine Structure
Kinematics of transient wave overtopping on coastal breakwaters has been studied both experimentally and numerically. For the laboratory experiments, solitary waves with moderate wave...
Modeling the Seasonal Circulation in Massachusetts Bay
An 18 month simulation of circulation was conducted in Massachusetts Bay, a roughly 35 m deep, 100×50 km embayment on the northeastern shelf of the United States. Using a variant of the...
Irregular Wave Run-Up on Composite Rough Slopes
Estimating Local Bed Shear Stress in Large Gravel-Bed Rivers
The local bed shear stress τo1 cannot be directly measured and is typically estimated using flow observations in various theoretical or empirical...
Modeling 3-D Ground Water Mounding
Groundwater mounding is caused by localized recharge to the saturated zone in an unconfined aquifer. Estimation of groundwater mounding shape and height is important to provide an estimate...
LDV System for Towing Tank Applications
The design, construction, testing, and operation of a two-dimensional LDV system for use in a towing tank is described. The primary design considerations were underwater application, minimal...
Implications of Stability Analysis for Heat Transfer at Yucca Mountain
An analytical solution has been obtained to the stability problem for an infinite horizontal layer of gas with its humidity constrained to 100%. Latent heat transfer makes convective heat...
An Object Oriented Relational Database for Assessing Radioactive Material Transport
EnviroView is an object oriented relational database used for inventory control and monitoring locations of radioactive and toxic materials. Visual images of local sites, building locations,...
Functional Analysis of the Exploratory Studies Facility
This paper discusses the development of the 'Physical System Requirements-Exploratory Studies Facility' (PSR-ESF) document. Based on a functional analysis approach, this document includes...
