An Extended Relaxation Technique for Unsteady Flows in Networks
A recent enhancement to the FLD WAY model is the addition of an extended relaxation technique for modeling unsteady flows in a dendritic (tree-type) network of channels with tributaries...
Two-dimensional Sheetflow Modeling for Wetland Restoration
The hydrologic-hydraulic behavior of wetlands and transitional upland-wetland areas on coastal flat terrains in the Cocohatchee Canal Watershed in Collier County, Florida was simulated...
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...
Santa Clara River Fluvial Analysis
The Santa Clara River watershed, located in Los Angeles County, has been subject to rapid increases in population and urban development, resulting in channelization, new bridges, and increased...
Simulation of Interaction between Canal Regulation and Groundwater
l-D canal routing module has been developed to perform the operation of controlled structures for regulating flow in the canal network system and incorporated in the Three-Dimensional...
The Last Two Extreme Floods in Germany?Analyses and Consequences
The last two extreme floods in Germany occurred in December 1993/January 1994 and January 1995 within the River Rhine basin with both floods having different causes. In a comparison study,...
The Largest Water Reservoirs of Russia in Flood Control
(Asbtract only) The largest water reservoirs of Russia, such as a reservoirs cascade on Volga and Kama Rivers, are used for solution of a number of water problems including flood control....
Large River Diversion Optimization Considering the Uncertainties Involved
Temporary river diversion during major construction (i.e., large dams) is a challenging job. Selection of diversion system capacity and the dimension of the system components are subject...
HOV Fix on I-66
Construction has been under way since December 1993 on a project to widen and add a high occupancy vehicle lane on a 12 mi section of Interstate 66 from Route 50 to the City of Manassas...
Soft-Ground Subway Construction
With its 89.5 route-mile system up and running, the Washington Metropolitan Transit Authority (WMATA) is now completing the $640 million Mid-City E Route. The new line presented formidable...
Cable-Stayed Canal Crossing
To lure some traffic from overburdened U.S. 13, a major north-south route on the Eastern Seaboard, Delaware is constructing a 47-mile relief route that will cross the C&O Canal...
Quasi-Two Dimensional Modelling of Flood Routing in Rivers and Flood Plains by Means of Storage Cells
A quasi-two dimensional numerical model for flood routing in rivers and flood plains has been developed. In the river, the St Venant equations are integrated using the implicit finite...
Real-Time Flood Forecasting Using Adaptive Estimation
The proposed flood forecasting system combines a flood routing model with a parameter estimation model. The flood routing model utilizes ?-index to determine the effective rainfall and...
