Evaluation of and Recommendations for Drop Structures in the Denver Metropolitan Area
In 1982, the Denver Urban Drainage and Flood Control District published interim guidelines for the design of sloped, loose riprap drop structures, as well as vertical wall drop structures...
The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...
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...
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...
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
Simulation of Sediment Transport in Coastal Water
The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model...
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...
Carichar?Mobile Bed Modeling with Graded Sediments
CARICHAR is a new system used for the computation of sediment transport. The coupled calculation of both water and graded sediments transport allows the simulation of sorting and armoring...
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...
Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...
Optimal Design of Large Scale Water Distribution Systems
This paper presents a methodology for the design of least cost water distribution systems. The advantage of the formulation compared to the other techniques in the literature is that it...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
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...
Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...
Water Distribution System Design by Chance-Constrained Model
The objective of this paper is to present an optimization model for the design of water distribution systems considering the uncertainty in required demands, required pressures, and pipe...
Analytical Simulation of Bulk Water Supply Network Reliability
The authors present an analytical method for estimating failure probabilities for a bulk water supply network with spatially dispersed supply, demand, and storage. The method examines...
Reliability Analysis of Pumping Stations and Storage Facilities
The methodology presented for pumping stations is based upon three models: a supply model, a demand model, and a margin model. The supply model considers so-called states of a system which...
