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....
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...
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...
Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...
Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...
Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
Design of Guide Banks for Bridge Abutment Protection
As an alternate to designing bridge abutments to withstand the development of the full scour prism predicted by equations currently available for estimating abutment scour, FHWA recommends...
Restoration Design for Urban Streams: Anacostia River Basin, Maryland
Several stream restoration projects have been undertaken by the Army Corps of Engineers in the Maryland portion of the Anacostia River basin. Measures used include bank stabilization,...
Design of a Floodplain Road Crossing Using Two Dimensional Modeling
A two dimensional hydraulic model (FESWMS) is prepared to evaluate flood conditions for the Canal Parkway Project, located in western Maryland. The parkway includes a 32 meter bridge replacement...
Large River Diversion Optimization Considering the Uncertainties Involved
Temporary river diversion during major construction (i.e., large dams) is a challenging job. Selection of diversion system capacity and the dimension of the system components are subject...
Rock Foundations
This manual provides technical criteria and guidance for the design of rock foundations for civil works or other similar large military structures. It provides a minimal standard to be...
