Geographical Information Systems and Remote Sensing: a possible support in 2D modelling of flood propagation
This paper examines some specific aspects regarding the implementation of a 2D mathematical model of flood propagation, namely that of input and output data management. The problems connected...

Combining a 2-D Flood Plain Model with GIS for Flood Delineation and Damage Assessment
This paper describes potential applications of Geographical Information System (GIS) for flood hazard delineation and damage assessment. The hydraulic model simulates both 1-D flood routing...

Object-Oriented Finite Volume Dam-Break Model
This paper is devoted to Object-Oriented analysis and design techniques to two computational modules in the field of dam-breaking. The C₊₊ Object-Oriented...

Two-Dimensional Modelling of Flow in the River Sava
On the river Sava near Ljubljana, a sports centre with a kayak racing channel was built in 1948. For the world championship in kayak-canoe racing in 1990 totally new racing channel had...

Flood Propagation on Mobile Beds under Mountainous Flow Conditions
An implicit finite-volume scheme is used to solve the shallow water equations under mountainous flow conditions. The algorithm is stable for sub- and supercritical flows and moving internal...

Kent, Edward
In order to perform conservative scour analyses for coastal bridge sites it is necessary to develop realistic hydraulic simulations which provide worst case estimates of depth and velocity....

Is Bedform Development Chaotic?
A qualitative analysis of a model for the partially specified bedform development system is presented. The study rests on the use of technique of loop analysis and the connection of the...

Stability Analysis of Rayleigh-Benard Convection in the Presence of Side Walls
The onset of laminar axisymmetric Rayleigh-Benard convection is investigated for a low-Prandtl number liquid metal in a cylindrical container, in the presence of a vertical temperature...

Interactive Models for the Regulation of Lake Ontario
Extensive studies are underway to improve the regulation of Lake Ontario. These studies not only involve the inclusion of factors and interest groups not previously considered, but also...

A Two-Dimensional Contaminant Transport Model with High-Resolution Upwind Schemes
High-resolution upwind schemes have become popular techniques to solve multidimensional transport problems. Based on the finite volume method (FVM), two-dimensional horizontal hydrodynamic...

An Integrated Shell (ROSS3) for Transport Modeling, Visualization, and Data Management
A model shell (ROSS3) which does visualization, data management, and modeling transport of oil and chemical spills in inland waters all within a single integrated unit is presented. Numerous...

Near Field Behavior of a Far Field Circulation Model
Output from the 3-D far field circulation model ECOMsi was compared with output from EPA initial mixing models in two simulations of coastal sewage outfalls - an idealization with steady...

Reconstruction of Concentration Boundary Condition for Unsteady Pesticide Transport Modeling
A one-dimensional unsteady contaminant transport model which used an unsteady hydraulic field was used to model pesticides (metolachlor, metribuzin) in the Iowa River/Coralville Reservoir....

Contaminant Fate and Transport Model in Pool-and-Riffle Streams
The complex nature of solute transport and transformation processes in natural streams has been investigated using numerical solution of a proposed mathematical model. This model is based...

Spectral and Parametric Wave Models of Lake Erie
The GLERL-Donelan parametric wave model and the SHALWV spectral wave model are presently being used as modules of the Great Lakes Forecasting System in order to determine which best fits...

GIS-Based Channel Extraction and Smoothing Algorithm for Distributed Hydrologic Modeling
An algorithm is developed to extract dendritic channel networks from Digital Elevation Model (DEM) data. This algorithm, in conjunction with the GRASS Geographic Information System (GIS),...

Genetic Algorithms in Groundwater Management
The aim of this paper is to examine applicability of genetic algorithms in groundwater planning and management. A brief description of genetic algorithms and the associated advantages...

An Attempt of an Aquifer Model with Lack of Data
The University of the Americas in Cholula, Puebla, Mexico withdraws water from an unconfined aquifer. Also the city of Cholula and the city of Puebla withdraw water too. A model aquifer...

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...

Movement of Colloids Under Hydraulic Gradients
A model was developed for analyzing the movement of colloidal clay particles in laboratory soil columns. The physical mechanisms of detachment of particles from the soil matrix, their...
