Methodology for the Optimal Reliability Based Design and Analysis of Pumping Systems for Water Distribution Networks
A methodology has been developed for the optimal (minimum cost) reliability based design of pumping systems. Two computer simulators, a reliability simulator and a hydraulic simulator,...
Hydrologic and Hydraulic Calibration?A Case Study (a)
The Addison Creek watershed is in Cook and DuPage Counties just west of Chicago, Illinois. Because the watershed has a history of major flooding, eight major stormwater and flood control...
A Linear Dynamic Programming Model for the Optimal Allocation of Water in Groundwater Dependent Areas
The purpose of this paper is to describe an efficient computer-aided planning method using linear and dynamic programming together with a finite difference groundwater model to determine...
A Ground Water Modeling Effort to Simulate the Results of An Aquifer Restoration Scheme
A ground water model using the IBM PC version of the USGS MODFLOW code was constructed to simulate the ground water flow beneath an industrial site in the central Midwest. A detailed three-dimensional...
TRUMPET: A TR20plus Watershed Model?Version 1.04
The TRUMPET watershed model is a microcomputer application which expands upon the widely used SCS TR20 hydrology computer program by providing user-friendly, interactive input and file...
Comparison of Two Methods for Modeling Urban Runoff
The techniques currently available for modeling urban runoff can generally be grouped into discrete and lumped system approaches. The storm water management model (SWMM) provides procedures...
Terrain Modelling for Computer-Aided Site Development
This research proposes a terrain model and a storm drainage model to be used as tools in creating a more efficient design/approval stage of the development process. This research proposes...
Daily Water Budget Model for Water Resources Management
A daily water budget model has been developed and tested for the Clinch and Powell watersheds located in SW Virginia and NE Tennessee. The model integrates available data and simulates...
Forecast Uncertainty in Reservoir Operation
Bayesian decision theory can be of significant value to reservoir operation because of its flexibility in being able to incorporate new information and/or opinions and judgments of decision...
Use of Stormwater Models to Optimize the Performance of a Regional Stormwater Detention System
implications of stormwater models to develop a regional detention basin master plan for Fairfax County, Virginia are described. Following the selection of candidate sites and detention...
Floodplain-Management Plan Enumeration
A branch-and-bound enumeration procedure can improve the search for an optimal floodplain-management plan. The procedure compares the net benefit of all possible combinations of proposed...
Continuous Drainage System Modeling of Jones Run
A generalized package of hydrologic and hydraulic models has been developed for the quantitative analysis of watersheds and drainage networks. The package is called ODWAP (the Old Dominion...
A Vectorized Polynomial Preconditioned Conjugate Gradient Solver Package for the USGS 3-D Ground-Water Model
A vectorized polynomial preconditioned conjugate gradient (PPCG) numerical algorithm is presented as an additional solver package interfaced with the Modular Three-Dimensional Finite Difference...
Computer Based Master Plans Manage Water Resources
Scottsdale is pursuing water and wastewater master planning with the goal of implementing a proactive water resources management policy. To prepare dynamic master plans with the above...
CLNET?A Computer Model for Tracking Movement, Decay, and Concentrations Throughout Water Distribution Systems
This paper describes a computer program package for modeling the spread and subsequent decay of chlorine for modeling as water travels throughout a water distribution system. This total...
Statistical Modeling of Space-Time Data
A common practice in hydrogeology is to draw contour lines to depict the occurrence of spatially distributed (i.e., regionalized) variables such as groundwater elevations, aquifer properties...
Towards a Better Simulation of Sea States for Modelling of Coastal Structures
In the last fifteen years, techniques of wave generation have advanced to such an extent that it is now possible to exercise controls of parameters such as wave grouping, wave asymmetries,...
Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...
Reshaping Breakwaters on the Stability of Roundheads and Trunk Erosion in Oblique Waves
The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at The Hydraulics laboratory, Department of Civil Engineering, University of Aalborg....
Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...
