Effects of Dissolved Air Flotation Hydraulic Loading Rate on Water Treatment Performance

Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...

Stepwise Flood Routing for Gated Reservoirs and Conjunctive Optimization of Hydroelectricity Income with Flood Losses
A six-stage operation policy for routing of flood hydrographs of return periods from 1.01 year up to the Probable Maximum Flood (PMF) for dams having gated spillways is suggested. The...

Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...

Robust Techniques for Extension of Streamflow Records
Longer hydrological records are required for the planning of water resource systems. Sensitivity of a system is studied under various scenarios of hydrological inputs to understand its...

Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...

Friction Factor Choice in Hydraulic Simulation Models: Does It Matter?
(no paper) To model water distribution systems using computer hydraulic simulation, a user is required to select a form of head loss-flow relationship for each pipe in the network. The...

Sensitivity of Stormwater Conveyance System Cost to Design Recurrence Interval
(No paper) The cost of a piped and/or swaled stormwater system is determined principally by the storm recurrence interval (e.g., 5-year design storm) used to design it. That is, the present...

A Leadtime Driven Flood Warning Response Plan Design
(No paper) The paper examines the optimal combination of predictive and detective capabilities in the development of the Wickenburg Flood Response Plan and extrapolates those findings...

Dewatering and Injection Testing for Design and Construction of the Fort Point Channel Crossing Project

A Joint Effort
In a public-private partnership that required close working relationships, a project that aimed to restore an old canal system— and its waterfront—in Richmond was combined with an effort...

The Ultimate Challenge
The U.S. Department of Energy (DOE) has spent $2 billion and more than a decade studying the feasibility of constructing a nuclear waste repository inside Yucca Mountain in Nevada. The...

Hydraulics of Open Channel Flow
This text is designed to make a deliberate effort to extend the modern fluid mechanics approach into the analysis of open channel flow without necessarily requiring the use of advanced...
