Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....

Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...

Pressure Fluctuations on the Floow of Hydraulic Jumps
This paper presents the results of an experimental investigation regarding the variation of r. m. s. value of pressure fluctuations on the floor of free and forced hydraulic jumps formed...

Stepped Spillway Design with a RCC Dam
The hydraulic model study results for the Upper Stillwater stepped spillway design are presented. The studies encompassed several spillway geometries and design unit discharges ranging...

A Stratified Mixing Channel: Theory and Experiment
The performance of a deep and stratified mixing channel is assessed theoretically and experimentally. The channel has a rectangular cross-section, a negligible longitudinal slope and is...

Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...

Hydraulic Design Limitations for Gravity Flexible (Non-Rigid) Plastic Pipes Flowing with a Free Water Surface
Hydraulic design limitations are necessary for gravity plastic pipes when designed for use as a sanitary sewer, flowing part full with a free water surface. The limitation for pipes designed...

A Tidal Hydraulic Model of the C&D Canal
The Kalman filter combined with one-dimensional shallow water wave equation is applied to describe the tidal hydraulic behavior of the Chesapeake Bay and Delaware bay canal. This model...

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...
