Projecting Climate Change to Small Basins: Potential Impact of Global Warming on Hurricane-Induced Flooding in South Florida
An important difficulty in evaluating potential hydrologic impacts of climate variability is that predictions of climate change require global simulation models that do not resolve phenomena...

Use of Models in Water Resource Systems: CRSS Experience
The Colorado River Simulation System (CRSS) is an in-house governmental computer-based model designed to be used as a decision support tool in performing long and mid range planning and...

Urban Hydrologic Modelling: HEC's Experience
Urban hydrologic modelling began at the Hydrologic Engineering Center (HEC) with the first versions of the HEC-1 Flood Hydrograph Package. The early applications were for large, primarily...

Uncertainty in Urban Hydrologic Modeling
Uncertainty is pervasive in hydrologic modeling. Uncertainty is present in the formulation of the physical situation to be modeled, in the form of the model to be used, in the boundary...

Model Mania in Urban Hydrology: Present Dilemmas
A recent ASCE Task Committee on microcomputer software in urban hydrology has just completed its inventory of 40 software packages available at modest cost to the urban drainage engineer....

Hydrologic Modeling for Decision-Makers
All Properties within a community benefit from having an adequate system of storm drainage facilities and controls. Such benefits include: reduction of hazards to property and life resulting...

A PC Method to Compile Land Use Data for Hydrology
A computerized method for compiling and reducing land use data for hydrologic computer model simulation was developed. The technique was developed for use on an IBM compatible PC. The...

The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...

Development of an Optimal Strategy for Storm Sewer Infrastructure Rehabilitation
Rehabilitation of the nation's infrastructure will require a significant expenditure of public funds in the near future. Efficient management of these funds will require tools...

Reliability Consideration in Capital Improvement Programs
This paper shows an application of network reliability modeling in water supply capital improvement programs. The proposed approach consists of combining geometrical and structural properties...

Optimization Model for the Control of Saltwater Intrusion
An optimization model is presented for the control of saltwater intrusion in the Jakarta groundwater basin. A quasi three dimensional, finite difference simulation model is used to predict...

Reliability of Model Prediction for Pump and Treat Strategies
For the remediation of aqueous phase plumes extending over large areas simulation models are often used to predict the response of the aquifer system and the contaminant concentrations...

Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...

Water Supply Network Modeling for Infrastructure Management
The concept of a graphics-based computer package for water supply network modeling and system management is discussed. Network model input and solution data are reported via color graphics...

Managing Water Supply and Demand with Integrated Computer Models
Water resource planning and management has greatly benefited from the use of computer modeling. Numerous computer models have been developed to predict expected outcomes given a set of...

Utility System Demand Forecasting Using Land Use Coefficients
In rapidly changing areas where several divergent paths of future growth are possible, there are advantages to forecasting future water demands and wastewater flows using the water and...

Integration of an ARC/INFO GIS with HEC-1
A hypothetical watershed was constructed to test the efficacy of using an ARC/INFO Geographic Information System to provide input for the U.S. Army Corps of Engineers HEC-1 hydrologic...

A Decision Support System for Water Supply Costing
Accurate cost estimates for water supply system expansions are an important component of the planning process. A spreadsheet-based cost estimating model called SWFCOST was developed as...

The Boundary Element Method in Engineering Practice
The advances in computer aided engineering has revolutionised many aspects of the engineering design in the last twenty years or so. During this time, design engineers have relied heavily...

Parallel Real-Time Dynamic Simulation of Robots
