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...

Automated Water Control in Southern Alberta
The distributed control system for water delivery that has evolved in Alberta, Canada is described including the type of hardware used and the general operating philosophy. Of importance...

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...

Effects of Land Subsidence on Flood Profiles
In this study, the effects of land subsidence on water-surface elevation and depth profiles during flood conditions were investigated for a large, hypothetical, slope-controlled stream....

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,...

Alternative Formulations for Water Quality Management Models
Various model formulations for water quality management are examined herein, each of which involves a somewhat different approach to the problem of determining optimal treatment levels...

Minimizing the Impact of Salinity Intrusion Due to Sea Level Rise
A rise in sea level will cause saline water to intrude up estuaries including those adjacent to aquifers with major pumping centers. During a drought a significant amount of saline estuary...

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...

The Effect of Water Supply and Sanitation Systems on Disease Patterns on Manitoba Indian Reserves
This study examines the links between water supply and sanitation and health on Indian reserves in Manitoba. Health data on water related diseases were obtained from health care agencies....

Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...

Recovery of Freshwater Stored in Saline Aquifers in Peninsular Florida
Subsurface freshwater storage has been operationally tested at seven sites in central and south Florida. Injection was into a high chloride water aquifer at six sites, and into a high...

Orleans Parish Drainage Improvements
A case study of the development of an urban drainage master plan for Orleans Parish, Louisiana is presented. The Parish, which occupies an area of approximately 98,000 acres, lies entirely...

Monitoring Groundwater Quality in the Southwest
Monitoring groundwater quality near sources of pollution in the southwest commonly involves highly productive alluvial aquifers. Experience in monitoring in such a setting indicates that...
