Solutions to Harbor Induced Erosion
Beach nourishment to mitigate shore damage attributed to Great Lakes harbor structures has been underway for over ten years. Experience has shown that using gravel/cobble size material...
Defending Our Lake Shores
The current high levels of the Great Lakes are nothing new, as the lakes have been fluctuating throughout history. There have been proposals to stop the current rise in the Michigan-Huron...
Sea Level Changes: A Corps of Engineers Perspective
The purpose of this discussion paper is to review current Corps of Engineers policy in relation to a possible significant increase in general sea level. A significant relative sea level...
Sea Level Change and Coastal Geomorphology of Padre Island, Mexico
Extending some 244 km from the Rio Bravo (Rio Grande) on the north to the mouth of the Rio Soto la Marina (at La Pesca) on the south, Padre Island, Mexico is comprised locally of several...
Field Observation of the Dynamics of Long Period Fluctuations in the Nearshore Zone
Controlled-leak Methods for Water Level Control
The controlled-leak methods are a group of similar techniques for controlling upstream water levels, downstream water levels, or offtake canal discharges. They require no electrical power...
Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...
Instrumentation for Automated Irrigation Systems
Remote site instrumentation sensors are vital components in automated irrigation systems, enabling measurement of water levels, flows and gate positions. It is desirable to select sensors...
Simultaneous Releases from a Stratified Reservoir
The concept of simultaneously, selectively withdrawing water from multiple levels in a thermally, and therefore density, stratified reservoir is presented and its usefulness discussed....
Air Regulated Siphons as Irrigation Canal Outlets
This paper investigates the possibility of using air regulated siphons as outlets from irrigation canals. Although a solution to a specific problem is sought, it is recognized that the...
Sea Level Rise and Estuarine Processes
The impacts of the projected sea level rise due to the greenhouse effect on the tidal hydraulics and the longitudinal and vertical distribution of the suspended sediment and salinity in...
Significance of Mean Water Level Response in Bays
The occurrence of a net hydraulic head, or superelevation, is a basic feature of bays. It is generated by inlet-bay response to natural forcing. The effects of bottom friction and Stokes...
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...
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...
Alternative Methods for Representing Sinkholes in Three-Dimensional Ground Water Flow Models
Two methods of representing the sinkholes in central Florida were investigated with a three-dimensional finite element model recently developed by Camp Dresser & McKee Inc. Both...
Settling Tank Model for Deposition in a Tidal Lagoon
A model is developed to assess deposition of suspended sediment in Great Sound, New Jersey. The model employs the classic settling tank concept which utilizes plug flow hydrodynamics,...
Investigation of Main Supply Canal and Lateral Fluctuations
The Imperial Irrigation District and the U. S. Water Conservation Laboratory of Phoenix, Arizona are conducting a joint project to study the causes and effects of water level fluctuations...
Probabilistic Forecasts of Continued High Great Lakes Water Levels
Existing projections of Great Lakes water levels over the next several years do not consider how meteorologic variability affects the hydrologic processes (basin runoff, overlake precipitation,...
Rescuing the Everglades
After a century of trying to control Florida's Everglades, water management officials have decided that cooperating with nature is better. A new strategy known as the Rainfall...
Modernization of Existing Hydroelectric Power Stations in Conjunction with Conversion to Automatic Operation
The easiest and, in the long run, the least expensive method in most cases is the installation of an electronic turbine governor that is not only easy to incorporate in the power station...
