Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...
Water Control Structure Choice for Wetland Restoration/Creation
Ducks Unlimited is a non-profit conservation organization, whose mission is to fulfil the annual life cycle needs of North American waterfowl by protecting, enhancing, restoring, and managing,...
Effect of Grade Control Structures on DEC Streams
Controlling the grade of a channel with structures has been an effective means applied to streams. Although, the effectiveness of grade control structures is not readily apparent until...
Siting of Grade Control Structures
In siting a grade control structure in a stream, hydraulic considerations must be integrated with other important siting factors. A review of several of the important siting factors is...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
Genetic Algorithm Design of Piped Irrigation Systems
The design of piped irrigation systems is a complex matter. In its simplest form it involves the selection of the sizes of pipes and other hydraulic elements so as to ensure that the varying...
Rational Design and Operation of Packed Bed Adsorption Reactors
Design of packed bed adsorption reactors is based presently upon the parameter empty bed contact time (EBCT), a fallacious concept. The column wave front behavior, instead, should be the...
Rock Riprap for Grade Control
Rock chutes (riprap channels on steep slopes) are used as grade control structures to safely conduct a water flow to a lower elevation. Common procedures used for design of rock riprap...
Grade-Control Structures for Salt River Channelization
Soil cement grade-control structures have been designed and constructed in conjunction with channelization projects along the Salt River in Phoenix, Arizona. The structures were designed...
Value Engineering Changes to the Eastside Pipeline
Value Engineering is a process of applying analytic, creative and evaluative techniques to a project in order to make recommendations that will, when implemented, maximize value and quality...
System Downstream Control for On-Demand Irrigation Canals
A nonlinear programming (NLP) Model has been developed to assist downstream control for optimal control of canal systems, called system downstream control (SDC). The objective of system...
Grade Control Structures for Pipeline Crossings in the Arid Southwest
Pipeline crossings at streams, rivers, and washes are at risk due to bed and bank erosion in the river environment. Buried pipelines may be exposed in the channel bottom by scour of bed...
Successful Implementation of Grouted Boulder Grade Control Structures on Drainageways in the Denver Metropolitan Area
This paper describes the development of design guidelines for the Grouted Sloping Boulder drop structure as an alternative for the sloping riprap drop structure. A number of partial failures...
Application of the Newton Method in Valve Discharge Coefficient Relationships
This paper presents a methodology that utilizes the Newton Method to compute the dimensionless valve discharge coefficient Cd from a manufacturers valve discharge coefficient Cv. The implicit...
Comparison of Water Backwash and Brush Cleaning Systems for Vertical Panel Fish Screens
Vertical plate fish screens have been installed at a number of locations within the Pacific Northwest The vertical orientation of the screen panels requires screen cleaning systems designed...
Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...
Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...
Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...
The Balanced Indigenous Population (BIP) and Statistical Process Control (SPC) in Marine Pollution Ecology
This account discusses the regulatory requirement of maintaining a Balanced Indigenous Population (BIP) as it relates to an ocean outfall. A brief history of the development of the BIP...
A Method to Study Suspended Sediment Induced Flow Characteristics Changes
Sediment-laden turbulent flows occur in nature and through man-made hydraulic structures. Our current understanding of this two-phase flow phenomenon is incomplete, and many important...
