Revegetation in the Arctic (
A tremendous amount of information on revegetation of Arctic tundra was gathered during the following completion of the Trans Alaska Pipeline System. This information and initiation of...
Tractive Flows Adjacent to Site for Submarine Sewage Pipeline
Twin 3200 m long submarine sewage pipelines for the city of Vancouver are being placed across the outer tidal flats and upper slope of the Fraser River delta to a water depth of 107 m....
New Tools for Economic Evaluation of Channel Deepening Projects
The Institute for Water Resources has developed a data base to facilitate economic evaluation of channel deepening projects. After extensive research, data elements were selected from...
Major Offsite Mitigation: Batiquitos Lagoon
This paper discusses the general characteristics of the Batiquitos Lagoon Enhancement Project near Carlsbad, California, which will provide mitigation for a pipeline project in San Pedro...
Investigation of Wave-Induced Oscillations in Sewage Outfalls
The work described in this paper deals with the effect of wave action on the hydraulic performance of a sewage effluent outfall. The outfall under consideration is an inverted siphon....
Can Alaskan Caribou and Oil Development Coexist?
The coastal area near Prudhoe Bay, Alaska is becoming increasingly industrialized as oil development continues. This same coastal area is an important area to a caribou herd known as the...
Caribou Mitigation in an Arctic Oilfield
The Kuparuk oilfield on the Arctic coastal plain of Alaska is in an area of traditional summer use by the Central Arctic Caribou Herd, who use it for calving, feeding, and insect relief....
Demand Irrigation Schedules
This class of schedules consists of Demand and Limited Rate Demand. They need no communication system and can satisfy the on-farm needs with negligible constraint. The Demand schedule...
Pipelines for Flexible Deliveries
The use of pipelines facilitates flexible deliveries for projects and flexible distribution on the farm. Pipelines have the advantage relative to canals in that they do not have to follow...
Pipeline Types and Design Considerations
Pipelines are extensively used to upgrade irrigation delivery facilities. The advantages of a pipeline system include an improvement in water conservation and the ability to extend water...
Design of Semi-Closed Pipeline Systems
Semi-closed pipeline systems controlled by downstream activated float valves permit low pressure pipeline systems to communicate information from the outflow location back to the source...
Case Study?Closed Pipeline Systems
The paper discusses closed pipeline system and its automation, including variable pumping rates, sensing devices, automatic controls, pressure regulators, flow measuring devices, surge...
Case Studies?Semi-Closed Pipeline Systems, Orange Cove and Solano Irrigation Districts
The Harris Float Valve is a simple mechanically leveraged valve connected to a float, which activates the valve with the rise and fall of the water surface on the down stream side of the...
Case Study?Open Pipeline System, Coachella Valley Water District
A supervisory canal control system installation was started in 1966, seventeen years after start up, and a major upgrading was completed in 1983. The canal delivery system now has a central...
Yakima-Tieton Irrigation District Rehabilitation Program
The Yakima-Tieton Irrigation District obtained funding from the U. S. Bureau of Reclamation and the State of Washington to replace an open canal and lateral irrigation delivery system...
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...
Numerical Modeling of Column Separation with Large Pressure Pulses
Liquid transients involving column separation occur in pipelines when the pressure drops to the vapor pressure of the liquid. The collapse of vapor cavities may result in short duration...
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...
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...
Developing a User Friendly System for Water Distribution Management Applications
A hydraulic computer model of a water distribution system that can be updated with current billing (customer meter readings) information automatically. The model was calibrated with field...
