Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...

Dam Safety Improvements for Tolt River Dam
Studies were performed to identify measures to improve the safety of the project under earthquake and extreme flood conditions while permitting the owner to store additional water under...

Underwater Inspection of Hydraulic Structures
Improvements in diving equipment, and underwater testing and instrumentation devices in recent years have increased the value of underwater inspections and reduced the cost. This paper...

Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...

Sea Level Rise and Estuarine Processes
The impacts of the projected sea level rise due to the greenhouse effect on the tidal hydraulics and the longitudinal and vertical distribution of the suspended sediment and salinity in...

Update: Fluidization for Tidal Channel Maintenance
Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved...

Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...

Polyhedric Surfaces
A new design for spillways is proposed. The basic idea is to substitute the traditional shape of the continuous vertical bends by polygonal plane surfaces. In this way it is possible to...

Applications of the Singular Point Method to Hydraulic Analysis of Spillways
A computer-oriented procedure is described to develop rating tables for side channel spillways. The procedure includes three sets of computations which have to be performed iteratively...

Hydraulic Design of Pamo Dam Spillway
The design of the emergency spillway for the San Diego County Water Authority's (SDCWA) proposed Pamo Dam is discussed. Pamo Dam is a 264-foot (80. 5 meter) high roller compacted...

Modeling Sediment Yield Affected by In-Stream Sand Mining
Sediment yield refers to the amount of sediment having passed a given river section for a specified duration. While sediment will be stored in the borrow pit, it will also be depleted...

Hydraulic Availability Evaluation of Urban Water Distribution Systems
This paper presents a concept for evaluating urban water system reliability using an extended period hydraulic simulation model in conjunction with mechanical availability analysis. Reliability...

Development of Scour Channel After Spillway Failure
In November 1985 parts of the spillway which controlled the water level in Lake Charleston failed during a moderate flood event. The spillway failure resulted in formation of a large 'sinkhole'...

Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...

Model for the Optimal Rehabilitation and Replacement of Water Distribution System Components
The objective of the model presented is to determine the minimum cost solution, given the nonlinear nature of the equations required to describe the cost and the hydraulics of a water...

Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...

Spring Creek Dam is Ready for the PMF: A Case History
Spring Creek Dam is the first earth embankment dam in Colorado, with inadequate spillway capacity, to be modified utilizing roller compacted concrete (RCC). With a structural height of...

Modelmania
The idea that model testing could be useful in planning for the control of water in rivers and other waterways received little support in this country until John R. Freeman's...

Evaluation of Sand as a Modeling Material Using Vellinga's Guidance
An experimental series of flume tests were conducted using three sizes of sand as modeling sediment in order to evaluate the effect of sediment grain size and the range of validity of...

Advanced Concept for Generation of Waves in Hydraulic Models
This paper describes a new wavemaker for the generation of naturally occurring waves in physical models of coastal areas. Recent research incorporating directional aspects of monochromatic,...
