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...

Transport Process of Surface Liquid Spills
A mathematical model simulating the scenarios of surface liquid spills is presented in this paper. This model describes the advance front and recession curves of surface spills based on...

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),...

Long Term Predictability of River Stages under ENSO Influence
The paper explores the bases for alternative approaches to river flow and hydrologic time series forecasting. The precipitation that forces river flow contains significant modes of variability...

Modeling of Maximum Velocity in Open-Channel Flow
A great deal of information about an open channel flow is contained in the maximum velocity, which, along with the entropy parameter, can determine the mean velocity. Therefore, the maximum...

Mathematical Models to Assess Stream Dynamics
A methodology is proposed to predict the behavior of meandering streams. Using a stream-shift model, lateral channel shift over a period of time is computed for several reaches with the...

A Lagrangian Model for Surface Buoyant Jets
A model is developed to predict the trajectory of a surface buoyant discharge into a large receiving water body. A Lagrangian approach is used to trace the path of a `control volume' of...

High-Resolution Upwind Schemes for Solving Mass Transport Equation
A fractional-step algorithm is employed to solve the mass transport equation by decomposing the advection-dispersion equation into two portions, pure advection and pure dispersion. High-resolution...

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...

Treatment of Nonhomogeneous Terms in Flow Models
A study of the relative significance and treatment of nonhomogeneous terms in unsteady open-channel flow simulation models has been conducted. The effects of nonhomogeneous terms including...

Steep Constructed Stream Channels and Chutes
Research and technology transfer needs are described for steep stream channels and chutes. Iterative processes are presented for design and construction of bouldery channels and chutes...

A Study on Mathematical Model for Sediment Yield in Mountain Regions with Large Hillside Slopes
Based on the characteristics of water and soil loss in mountain region with large hillside slopes in southwest of China, the equations of runoff formation and sediment yield are obtained....

Ambrose, R. B.
Numerous three-dimensional hydrodynamic models have been developed in the last two decades. The developers of each model have used their own methods to verify the codes before applying...

Estimation of Design Surge Heights by Utilizing Meteorologic and Oceanographic Data
Data on cyclonic storm surge height have been generated with the help of a statistical simulation model. Data on observed maximum cyclonic wind speed and the length of the continental...

Discharge-Frequency Relationships in Distributary Flow Systems
The paper describes discharge-frequency relationships in distributary flow systems. The stream network that makes up the flow system is described in terms of how the various stream segments...

Evaluating an Autoregressive Model for Stream Flow Forecasting
Daily stream discharge generated by an Autoregressive Model is helpful in the design and risk assessment of temporary riverine construction projects. This case study uses actual daily...

A Watershed Model for Estimating Suspended Sediment Hydrographs
A mathematical model was developed to estimate soil detachment and transport and, consequently, suspended sediment hydrograph for single storms on a watershed basis. In this linear cascade...

Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...

General Urban Runoff Model for Water Quality Investigations
This paper presents and examines a general urban runoff model appropriate for water quality studies. The model is applied to separate runoff source areas and the outfall conditions are...

Modeling Ecological Impacts of Destratification
Artificial destratification has long been advocated as a means of improving water quality in lakes and reservoirs. The results have been varied with examples of both water quality improvement...
