Canal Control and Automation for the Central District System
The Central Nebraska Public Power and Irrigation District system provides irrigation and hydropower benefits in south-central Nebraska. Because of its complexity, the system relies heavily...

Hydraulic Design of Subsurface Flow Wetlands
Although Subsurface Flow Wetlands (SFW) have received steadily increasing international attention during the past 10 to 15 years, comprehensive design criteria are not available for some...

Selection of the Form of Calculated Flood Hydrograph in Projecting Water Release Facilities
Traditionally, in evaluating hydraulic structures, river flood runoff hydrographs are determined by maximum flood water volume and discharge, duration of the flood and some other parameters,...

Risk-based Analysis of Major Rehabilitation of Hydraulic Structures Using REPAIR
This poster session presents a demonstration of a computer model developed by the Corps of Engineers to analyze investment proposals. The primary purpose of the model is evaluate investments...

Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...

Maryland SHA's Procedure for Assessing Existing Bridges for Scour Vulnerability and for Rating Unknown Foundations
The Maryland State Highway Administration developed a recommended screening procedure for rating existing bridges for Item 113, Scour Critical Bridges, in the National Bridge Inventory...

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...

The Analysis of the Failure of the Minte Stream Culvert
A persistent and continuous rainfall that lasted for more than 30 hours on May 6?7, 1995, caused the sudden failure of an embank ment on the main road between Puerto Varas and Ensenada,...

Protection against Flooding: A New Delta Plan in the Netherlands
The Netherlands are situated on the delta of three of Europe's main rivers: the Rhine, the Meuse, and the Scheldt. As a result, the country has been able to develop into an important industrial...

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...

3D Flow Structures?From Laboratory to Field Applications
One laboratory experiment and one field application have been modeled. For each one different sources of errors in the model results could be detected. It may be concluded that the applicability...

The Cost of Highway Bridge Scour in the State of Minnesota
Different states are faced with different conditions with respect to geology, topography, climate, native vegetation types, bridge ownership, and bridges management systems, which in turn...

Tributary No. 9 Restoration, Maryland State Highway Administration
The Maryland State Highway Administration agreed to accomplish restoration of 1,100 feet of stream channel as part of a mitigation agreement with the U.S. Army Corps of Engineers, Baltimore...

Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...

Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...

Dam Foundation Erosion Study: Pit 4 Scale Model Simulation
This paper describes the results of a sub task of the Dam Foundation Erosion Study, a cooperative research study by Reclamation, PG&E, Colorado State University, and Western Area...

On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...

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...
