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...

Farakka Barrage - It's Impacts and Possible Mitigation
The paper discusses the impacts and possible implications of the Farraka Barrage Project across the Ganges River on different sectors in Bangladesh including hydrology and river morphology,...

Hydrodynamic Modeling of San Diego Bay
A two-dimensional vertically-averaged finite element model was adapted to study the hydrodynamics of San Diego Bay. The hydrodynamic model was interfaced with pre- and post-processors...

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...

A model to describe the fate of agricultural pollutants
The distributed parameter hydrological model CEQUEAU is coupled to nitrogen and pesticide sub-models to study agricultural non-point pollution at the watershed level. This developing tool...

The Great Lakes Forecasting System: An Overview
The Great Lakes Forecasting System is a full three-dimensional model-based system designed to make regularly scheduled predictions of the physical status of each of the Great Lakes. Due...

Daily Procedure for GLFS Nowcasts
The Great Lakes Forecasting System (GLFS) is an integrated system involving three levels of computational power for making predictions. GLFS consists of three-dimensional numerical circulation...

Impact of GOES Data on Surface Heat Flux Predictions
Surface heat flux is the required input for the Great Lakes Forecasting System (GLFS) in order to predict three dimensional temperature structure of the Great Lakes. Since the flux is...

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),...

Predictability and Sensitivity of Groundwater Transport Models
The uncertainty associated with predictions made by solute transport models in groundwater environments must be carefully evaluated to address spatial and time variability as well as data...

Groundwater Development and Related Issues
Optimum development and management of ground water resources requires consideration of all elements of the groundwater system and their inter-relations with total hydrologic cycle along...

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...

Effect of Data Sampling Time Resolution on Probability Distribution of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is useful information in statistical forecasting of rainfall and runoff. The probability density function (pdf) of the elapsed time can be determined...

Flood Monitoring Network In Southeastern Louisiana
A flood monitoring network has been established to alert emergency operations personnel and the public about hydrologic conditions in the Amite River Basin. The U.S. Geological Survey...

Combination of an Automated Channel Network Extracting System and a Distributed Watershed Model in Estimation Rainfall-Runoff Processes
Due to the improvement of accuracy and availability of Digital Elevation Models (DEMs), hydrologic researches which utilize DEMs have gradually reached sound results. In this paper, we...
