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...
Two-Dimensional Inter-Rill Flow Model for the Analysis of Agricultural Runoff
This paper presents a model describing the flow field for the inter-rill component of agricultural runoff. Given rainfall intensity, surface roughness, rill spacing, and longitudinal and...
Overfall Stress and Pressure Distributions
The magnitude and distribution of hydraulic shear stress and pressure on the boundary of a straight drop overfall are presented for multiple overfall heights and flow rates. Hydraulic...
Jet Injection Model Studies for the City of Los Angeles
The Hypersion Treatment Plant for the City of Los Angeles is currently undergoing an expansion project. A major component of this system is a sludge recycling system. And it is essential...
Energy Dissipation Structure for Fixed-Cone Valves
Results of a model study to investigate the hydraulic performance of a proposed energy dissipation structure for fixed-cone valves are presented. Procedures for estimating pressures and...
Prediction of Siltation at a Point
This paper describes a zero-dimensional mathematical model which predicts siltation at a point on a cohesive sediment bed. The processes of erosion, deposition and consolidation are modelled...
High-Resolution Two Dimensional Advective Transport
The paper describes a two-dimensional high-resolution scheme for advective transport that is based on a Eulerian-Lagrangian method with a flux limiter. The scheme is applied to the problem...
