Floodplain Delineation of the Ranillas Meander in Zaragoza Using GUAD-2D
After the selection of Zaragoza (Spain) as the host city of the International Expo 2008, the
The Accuracy of Extrapolated Design Estimates with Hydrologic and Environmental Models
Extrapolation error in water resources and environmental modeling has not been the subject of adequate study in the past. In research and design, estimates obtained from regression models...
One-Dimensional Model Accurately Predicts Concrete Temperatures
Evaluation of Two-Species Model for Chlorine Decay and THM Formation under Rechlorination Conditions
(No paper) Typically, chlorine decay has been described by a first-order decay model. The first-order model, however, has two drawbacks: 1) the reactive species within the water is assumed...
All Decked Out
After 50 years of wear, the deck of New York City's Williamsburg Bridge was buckling and badly in need of replacement. In 1994, consultants recommended replacing the deck...
Sim City of Angels
Using advanced computing techniques, UCLA researchers are developing a virtual model of the entire 4,000 sp mi Los Angeles basin. Accurate to the level of graffiti on the walls and store...

Dormant Season Evaporation: Challenges to the Current Models
Dormant season evaporation is a critical component of the hydrologic balance and can be considered as the winter period or the time in which there is not a crop actively growing. It is...
Nongrowing Season Evaporation in Northern Utah
Dormant season evaporation is a critical component of the hydrologic balance and can be considered as the winter period or the time in which there is not a crop actively growing. It is...
An LPI Numerical Implicit Solution for Unsteady Mixed-Flow Simulation
A Local Partial Inertia (LPI) technique is developed as an option within the National Weather Service (NWS) FLDWAV dynamic flood routing model to enhance its capability to model unsteady...
Depth-Averaged Boussinesq Equations Applied to Flow in a Converging Channel
Supereritical flow in a contracting channel is simulated by numerically solving the 2D depth-averaged Boussinesq equations using a fmite-difference model DASH (Molls and Chaudhry 1995,...
CSO Planning Model Development and Verification Strategy
A model verification technique is described that uses modeled and monitored overflow occurrences defined in terms of the same long-term frequency statistics that are used to evaluate CSO...
Indianapolis Uses New Radar Technology to Refine Hyetographs for CSO Model and SSES Studies
Indianapolis is the first city in the country to install the French-developed technology designed by urban hydrologists to accurately measure rainfall between rain gauges. Installed in...
Mitigation of Flood Hazard on Alluvial Fans
A number of investigators have suggested that the limits of the traditional, stochastic, one-dimensional model of alluvial fan flooding have been reached and that there are one- and two-dimensional...
Accuracy of a 3D Hydrodynamic Model Verification due to the Relative Magnitude of Forcing Functions
An investigation of relative magnitude of forcing functions in a 3D time-varying hydrodynamic model verification has been performed by identifying some extreme forcing events for an estuarine...
Increasing Computational Accuracy of Radial Gate Flows
Radial (Tainter) gates are the most widely used flow control structure on large, open channel conveyance systems. In contrast, the hydraulic forces are complicated and this type of gate...
Transport Modeling of the Coastal Waters of Oahu, Hawaii
A hydrodynamic model of the coastal waters around the island of Oahu, Hawaii has been constructed to provide quantitative information on the movements and mixing of water that are to be...
