Hydrodynamics of Earth Fill Dam Breach Erosion
An analytical model is suggested in this paper. The model is based on the continuity equation of water mass within the reservoir, a broad-crested weir discharge formula and a velocity...
Coupling of Hydrodynamic and Water Quality Models
Long term, multi-dimensional water quality modeling in estuaries and coastal embayments using a directly linked hydrodynamic and water quality model can be prohibitively expensive. In...
The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...
A 2-D Model for the Guaiba Estuary (Brazil)
On the northeastern edge of the Guaiba is Porto Alegre, with more than 1 million inhabitants. A navigation channel through the Guaiba Estuary and the Patos Lagoon links the city to the...
Hydrodynamic Simulation of the Upper Potomac Estuary
Hydrodynamics of the upper extent of the Potomac Estuary between Indian Head and Morgantown, Md. , are simulated using a two-dimensional model. The model computes water-surface elevations...
Water Quality and Hydrodynamics in a Shallow Lake
Hydrodynamics and water quality are closely coupled in a shallow lake via horizontal transport and sediment resuspension. The latter process is examined thru modeling and in situ field...
Estuarine Hydrodynamic Modeling on MicroComputers
The program for a two dimensional finite difference estuarine model was adapted for use on a modified IBM-PC/XT microcomputer. Commercially available hardware and supporting software were...
Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
Friction in Hurricane Induced Surges
Bed shear stresses induced by the flowing water are expressed by means of a friction factor for which formulas are developed for: ocean bottom, mangrove fringes and areas, forested areas...
Simulation of Wetland Hydrology and Hydrodynamics
The relative changes in water stage in swamps and marshes and the variations of current velocities in bayous and canals under present conditions are calculated, using a computer watershed...
Numerical Waterbody Dynamics and Small Computers
The numerical hydrodynamics of free surface flows as applied to waterbodies presents a number of challenges, including choice of the spatial differencing schemes including representation...
Report of the Task Committee on Test Cases for Verification of 2-D Depth-Averaged Hydrodynamic Models
The Computational Hydraulics Committee has established a Task Committee to identify test cases which can form a uniform, objective basis for model verification. The scope is limited to...
Hydrodynamic Model of River Flow on a Microcomputer
This paper presents a one-dimensional, finite element model for simulating hydrodynamic responses to various conditions on a river system by using microcomputers. Based on the Saint-Venant...
Fundamentals of Agitation Dredging
