STUDH: A Two-Dimensional Numerical Model for Sediment Transport
TABS-2 water level and flow computations are performed by the generalized numerical model program RMA-2V; salinity and tracer transport computations are performed with RMA-4, and sediment...
Estimation of the Effect of Land Use Changes on Storm-Event Sediment Yield from a Small Watershed
The influence of partial deforestation in a small lowland watershed in the center of Poland on storm-event sediment yield is analysed. Rainfall-runoff model has been applied to estimate...
Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...
Reservoir Sedimentation Mathematical Modeling
The main objective for this paper is to show how one can predict the sediment movement, and estimate the volume of the deposited sediments, which is considered as one of the factor affecting...
Stochastic Modeling and Generation of Droughts
Stochastic simulation was used for deriving drought properties of the Poudre River, Colorado and the Red River, North Dakota. The autoregressive moving average (ARMA) model and a threshold...
Boundary Conditions of Tidal Model at River Mouth
A small grid is required to schematize irregular shape of shoreline in the vicinity of river mouth which limits the modeling area to be small. Tidal records along the boundary show no...
Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...
Improved Numerical Analysis of Steady Water Surface Profiles
As well as HEC-2 and similar models serve the profession, problems exist with their application. In general, inflexibility of use and inaccuracies around transitions between subcritical...
Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....
Groundwater Monitoring Network Design Using Coupled Monte Carlo Simulation and Optimization
This paper presents a method for the design, under uncertainty, of a groundwater well network for compliance monitoring at a waste disposal site. A numerical model of contaminant transport...
A Real-time Approach to Groundwater Monitoring, Prediction, and Remediation
This paper outlines a integrated approach to the problem of predicting and controlling groundwater contamination. The key to this approach is to derive contaminant predictions by combining...
Validation and Intercomparison of Three-Dimensional Numerical Models of Estuarine and Lake Hydrodynamics
Three-dimensional numerical models have been developed and used to study the circulation and transport of water quality parameters in estuaries and lakes. This paper discusses two important...
The Use of Distributed Rainfall-Runoff Models Based on GIS at Different Scales of Information
The effects of spatial variability of soil type and land use on basin response are investigated. This is modelled thorugh a distributed approach specifically designed for calibration from...
Application of Hydrodynamic and Water Quality Models at a Superfund Site in Montana
The water quality model applied to the site is the EPA-supported hydrodynamic and water quality model WASP4 with a modification to enable it to better simulate riverine systems. To provide...
An Analytical Solution to Verify a Nonlinear Tidal Circulation Model
