Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
The Estimation of Extreme Floods in Brazil
In Brazil, the design flood of a large dam is calculated using either the Probable Maximum Flood criteria or the 10,000-year Flood. Recently a Guidebook has been written to help Brazilian...
GEOPACK: A Geostatistical Software System
A comprehensive, user-friendly geostatistical software system called GEOPACK has been developed. The purpose of this software is to make available the programs necessary to undertake a...
An Overview of Coastal Stormwater Drainage Problems
Considerable studies have focused on the drainage design in upland areas. In the Atlantic and Gulf Coastal region, the stormwater drainage presents many unique problems mainly due to the...
Design of Expansions for Sub-Critical Open Channel Flow
Expansions for open channel flow at sub-critical velocity are required whenever it is necessary to reduce the velocity of flow from a structure which discharges into an erodible channel....
Hydraulic Design of Mud Mountain Dam Outlet Works Modifications
Mud Mountain Dam is a single-purpose flood control project located on the White River in western Washington State. The existing flood control outlet works consist of an upstream controlled...
Cocohatchee River Basin Study
The report presents the modeling of the Cocohatchee River basin, including 2-D routings for wetland regimes, hydrologic/hydraulic analyses of the agricultural and suburban land uses, and...
Special Hydraulic Problems Related to Coastal Louisiana Drainage Systems
The urbanized coastal areas of southeast Louisiana present unique problems for hydraulic engineers. These problems relate to the design of drainage systems serving leveed areas with flat...
Water Distribution System Design Considering Component Failure During Static Conditions
A continuous hydraulic availability relationship is presented which more realistically models minimum pressure requirements for water distribution systems. This relationship is used in...
Optimal Reliability Based Design for Water Distribution Systems
The methodology presented in this paper explicitly includes availability measures that incorporate both mechanical and hydraulic unavailability of system components for a dynamic system....
Drainage Problems in a Highly-Developed Shoreline Area
Hilton Head Island, South Carolina, is a 42-square mile barrier island on the south-east coast Flooding of roads and properties is a continual problem in this low-lying, flat area due...
Low-Land Hydraulics and Hydrodynamics
A hydrodynamic model is presented for simulation of wetland hydrodynamics. The model incorporates all elements of the hydrologic cycle, such as precipitation, runoff, groundwater seepage...
Two Case Studies of Stochastic Identification of Aquifer Hydraulic Parameters and Natural Recharge
A method to identify aquifer transmissivity, storativity and natural recharge (inverse modeling), based on a geostatistical approach is presented. The basic assumptions of the method are...
Seven Oaks Dam Outlet Works Design
The U.S. Army Corps of Engineers has completed the preliminary design of the outlet works for the proposed Seven Oaks Dam. The dam is the upstream-most feature of the Corps'...
Sediment Ramping at Mill Creek
A Corps of Engineers study completed in 1988 analyzed this ramping phenomenon Mill Creek in Southern California Using an approach which combined sedimentation research with Corps experience...
Lower Santa Ana River Hydraulic Design for Levee Overtopping
The purpose of overtopping or freeboard design is to minimize damages and catastrophic failure from floodwaters overtopping levees. This case study is presented to show the approach taken...
Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...
Physical Modeling of Heated Discharges into a Stagnant River
An alternative cooling system study was performed for the Damietta Combined Cycle Plant in Egypt. The alternatives included spray canals, helper cooling tower and once-through cooling....
Model Study of New Madrid Pumping Station
The proposed pumping station on the New Madrid Floodway consisted of a draft tube type sump design (referred to as a formed suction inlet) to eliminate swirl and provide a more uniform...
Hydraulic Analysis of the Schoharie Creek Bridge
Ten people died on April 5, 1987 as a result of the collapse of two spans of a New York State Thruway bridge into the floodwaters of Schoharie Creek. The cause of the bridge failure was...
