European Progress on river Renaturalisation
Most restoration projects in Europe have been designed to maximise species richness with little regard for channel stability. To recreate a sustainable natural channel it is necessary...
Utilizing Geomorphic Analogs for Design of Natural Stream Channels
Engineering guidelines for the design of stable rock armored channels are well established. However, few guidelines exist for designers involved with the reconstruction of channels with...
Stormwater Management for San Joaquin Hills Transportation Corridor, Orange County, California
San Joaquin Hifis Transportation Corridor (SJHTC or Corridor) is one of the largest design-build toll roads in U.S.A. To meet stringent environmental mitigation requirements, to ensure...
Impact of Reservoir Flood-Control Operation on Interior-Drainage Facilities
Sacramento, CA is protected from floods of the American River by Folsom Dam and a system of levees. Proposed modifications to the flood-control operation of Folsom will increase downstream...
Design Guidelines for UV Disinfection Facilities
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....
Numerical Modeling of Flows in Ultraviolet Disinfection Channels
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....
Flood Management Strategies for the Rhine and Maas Rivers in the Netherlands
This paper addresses the above issues, examines the lessons learned, and emphasizes the shift in attention from society on flood management issues. Special attention is devoted to the...
Measurements of Bridge-Scour Depths in Mississippi
This paper briefly summarizes 190 measured pier-scour depths collected dur ing 1942?94 at 22 selected bridges in Mississippi and presents an envelope-curve equation for the data. The envelope-curve...
Design Guidance?Instream and Bank Restoration Structures
Despite an urgent need for river and stream restoration design criteria, little guidance has emerged in recent years. Existing guidance is largely unsatisfactory, promoting empiricism...
Design Guidelines for Bioengineered Bank Stabilization
Design of bioengineered slope stabilization measures in riverine environments to minimize rates of stream bank erosion requires accounting for hydrologic, hydraulic, geomorphic, geotechnical,...
River Restoration Considerations Beyond Channel Design
Restoration of river systems in highly disturbed environments poses unique challenges beyond channel design. The Jordan Creek Restoration project in Idaho was conducted in a valley disturbed...
Navigation Lock Improvements
All commercial barge traffic on the Upper Mississippi River and Illinois Waterway must pass through a system of locks designed and built in the 1930s and 40s. Many of the locks on these...
McAlpine Intake Model Study for Innovative Lock Design
The McAlpine Locks and Dam Project is located on the Ohio River near Louisville Kentucky. Construction of an additional 33.53-m-wide (110 ft) by 365.76-m-long (1200 ft) navigation lock...
Filling and Emptying System Model Study for the Innovative Lock Design
Funding constraints have generated innovative ideas regarding the hydraulic system of proposed navigation locks. Two fundamental questions addressed in the innovative lock design study...
Influence of Flooding Events on Suspended Matter Quality of the Meuse River (The Netherlands)
Flooding events of the Rhine and Meuse Rivers have struck The Netherlands in 1993 and 1995. In the Meuse River basin, the river forelands have been widely used for housing and agro-industrial...
Sims Bayou: The Public Speaks?The Corps Listens
After about ten years of coordinating, planning, engineering, and design, advertising the first construction contract for the Sims Bayou flood control project was only months away. At...
Evaluating Hydraulic Roughness in Tunnels
Much of the data presented in the literature on measured friction losses in tunnels are given in terms of the Darcy-Weisbach
A New Technique for Measuring Vegetation Density
Detennination of the discharge capacity of a vegetated channel or floodplain requires a reasonable estimate of a flow resistance coefficient; such as Manning'
Hydraulic Model Study of the Prado Dam Spillway
The existing Prado Dam, located in the City of Corona, CA, is deficient in providing adequate flood protection to the Santa Ana River floodplain downstream of the dam. To provide adequate...
Observations of Tidal Circulation in Mamala Bay, Hawaii
A comprehensive measurement program, designed to study circulation processes and support hydrodynamic modeling, has been carried out in Mamala Bay on the south coast of the Island of Oahu,...
