A Tidal Hydraulic Model of the C&D Canal
The Kalman filter combined with one-dimensional shallow water wave equation is applied to describe the tidal hydraulic behavior of the Chesapeake Bay and Delaware bay canal. This model...
Flume Measures Ultra-Wide Discharge Range
Advances in mathematical modeling in the mid-1970's have led to accurate modeling of discharge and energy loss characteristics of long-throated flumes. A complex long-throated...
Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...
Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...
Rehabilitation of Williams Bridge Dam
Pennsylvania Gas and Water Company initiated construction work to upgrade the 90-year old dam in order to meet current dam safety standards with emphasis on satisfying Probable Maximum...
Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...
An Investigation of the Alcatraz Disposal Site
The Alcatraz dredged material disposal site in San Francisco Bay is a dispersive site that is not intended to accumulate disposed sediment. However, the recent discovery of shoaling at...
Numerical Model Evaluation of Advance Maintenance
Improving and maintaining navigation harbors and channels is one of the key functions of the US Army Corps of Engineers. The present cost-sharing system and the increasing costs associated...
Mathematical Simulation of Halocarbon Distributions in Boston Harbor
In an effort to better understand the sources and transport of effluents, a combined modeling and field measurement program has been initiated. The modeling uses a pair of 2-D (depth-averaged)...
Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...
Effect of Atmospheric Forcing on Tide Propagation
This paper presents computations and observations indicating that nonlinear interaction with wind waves and subtidal sea level changes can change estuarine motion in the tidal frequency...
Hydraulic Design of Pamo Dam Spillway
The design of the emergency spillway for the San Diego County Water Authority's (SDCWA) proposed Pamo Dam is discussed. Pamo Dam is a 264-foot (80. 5 meter) high roller compacted...
Lower Mississippi River Salt Intrusion Modeling
A laterally averaged numerical model called LAEM has been employed for both a 40- and 55-ft channel. In addition, LAEM has been applied with an increased height of the natural river crossing...
Longitudinal Dispersion in Partially-Mixed Estuaries
The longitudinal dispersion in partially-mixed estuaries was formulated to consist of two terms. The first term accounts for the dispersion due to the vertical and transverse shear of...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
Analysis of Scour Problems at Louisiana Bridges
An ongoing project to automate the monitoring of scour measurements at Louisiana bridge sites is discussed. The data at selected bridges is digitized and put into computer files for analysis....
Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...
Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...
Design of Overtopping Protection for Small Dams
Many existing small embankment dams in the United States cannot safely pass current design floods without overtopping. In the past several years, embankment overtopping protection has...
Spring Creek Dam is Ready for the PMF: A Case History
Spring Creek Dam is the first earth embankment dam in Colorado, with inadequate spillway capacity, to be modified utilizing roller compacted concrete (RCC). With a structural height of...
