Retrofitting a Detention Facility for Improved Quantity Control
Historically, detention facilities in the U.S. were first designed, constructed and operated for the single purpose of flood control. This led to a second phase, in which recreation and...
Reservoir Regulation and Real-Time Models for Trinity River Flood Prevention and Control
After unprecedented flooding from the Spring of 1989 through 1991 in the Trinity River basin, the Texas legislature allocated funds for flood related studies in Senate Bill 1543 (1991)....
Streamflow Forecasting for the Bradley Lake Project
The National Weather Service (NWS) uses a suite of software called NWS River Forecast System (NWSRFS) for operational river stage and streamflow forecasting. NWSRFS is a modular system...
A Method for Conducting Real Time Flood Forecast
In this paper, first, it explains about the real time flood forecast which must be conducted at rivers in Japan. Next, as a means to an end, it is proposing the utilization of runoff computation...
National Weather Service Operational River Forecasting in a UNIX Environment
The mission of the National Weather Service (NWS) includes providing river and flood forecasts and warnings for protection of life and property, and providing basic hydrologic forecast...
Real-Time Dynamic Flood Routing with NWS FLDWAV Model Using Kalman Filter Updating
Dynamic flood routing model based on the four-point implicit finite-difference solution of the complete one-dimensional Saint-Venant equations of unsteady flow are inherently deterministic....
A National System for Threshold Runoff Estimation
Threshold runoff is the amount of effective (or excess) rainfall of a given duration uniformly distributed over a certain catchment that is just enough to cause flooding at the outlet...
County Hydrology, Regional Approach
The effort to update the regional hydrology methods of the Santa Clara Valley Water District (District) entails a series of tasks that are long and difficult. This paper enumerates the...
River Characteristics of the Blue Nile Watershed
A common difficulty in modeling hydrological systems is the lack of available field data to assess the model parameters. In some cases, it is physically very difficult and expensive to...
Linear Pertubation Model: An Application to Tanzanian Catchments
Floods are still a problem to many countries in the world todate. Floods do cause damage to property and sometimes loss to human life. Flood control measures by structural and non-structural...
HEC's Project Benefit Accomplishment Program
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has developed a new computer program which computes flood damage and project benefit accomplishment. It calculates...
Large Flood Plains Modeling by a Cell Scheme: Application to the Pantanal of Mato Grosso
The computational modeling of large flood plains presents difficulties related to the mathematical approach of the phenomenon and also to the discretization of the area under study. In...
Acidity and Chemistry of Arizona's Snowpacks
Acid snow, the frozen version of the acid rain phenomena, has been sampled in several western states, e.g., California, Nevada, Montana, and Oregon. Measurements of snowpack acidity in...
Regulatory Obstacles to Emergency Response, A Case Study of the Paint Fire, June 1990, Santa Barbara, California
After the Paint Fire of 1990, the Santa Barbara County Flood Control and Water Conservation District took several measures to prevent damage due to mudslides and floods from the burned...
Simulation of Rapid Reservoir Drawdown for Flood Control, Cowlitz Falls Project
The Cowlitz Falls Dam is a run-of-river project, currently under construction on the Cowlitz River in Washington State, 23 Km downstream from the town of Randle. The requirements for reservoir...
Sedimentation and Flood Protection for the Lower Yellow River
The Lower Yellow River is known for its disastrous floods in the past. After 4 decades without major floodings, rapid economic and population growths along the River have drew concerns...
Dune Profiles Before and After Storm Events in Coastal Massachusetts
It is well known that short-term changes in dune profiles can have a major effect on the severity of storm damage to coastal areas. In light of this, the standardized methodology developed...
Uncertainties of Tailwater in an Inundation Study: Dam Upgrade Optimization for Hazard Reduction
When an upgrade is required for a dam with an inadequate spillway system, the potential impact of tailwater during an extreme storm in an inundation study should be considered. This paper...
Federal Levee Effects on Flood Heights Near St. Louis
A physical model of the Middle Mississippi River was used to perform quantitative analyses of Federal levee effects on flood heights. Contrary to some opinions of the general public, these...
Case History: 100-Year Flood Event in San Francisco
San Francisco experienced a 100-year storm in the winter of 1981-2. This is a report of the flooding damage from this event and the actions that the City took to resolve the flooding problems....
