Late Quaternary (Pre-Holocene) Coastal Systems of New Jersey
The coastline and the area adjacent to the present shoreline of New Jersey has not been explored as intensely as the same region of neighboring states for pre-Holocene high sea level stillstands....

Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...

Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...

Topographic Responses to the Construction of Large Port Structures on Oarai Coast
Large offshore breakwater and groins have been constructed at Oarai Port, Japan. As a result, the coast experienced significant topographic changes. In this paper, the responses of the...

Preliminary Investigation into Using Oxidation-Reduction Potential (ORP) for Real-Time Control of Aerobic-Anoxic Sludge Digesters
This research explores the use of Oxidation-Reduction Potential (ORP) to control an Aerobic-Anoxic Sludge Digestion Process. It compares a Fixed-Time Control reactor (3 hours of air on/3...

Composting, Past, Present and Future
Over the past ten years, the composting process has taken on a different look as a method of processing municipal sludge. Today it is one of the most popular and prevalent methods of sludge...

Modeling Analysis of CSO Impacts in a Tidal Basin
Short duration intensive inflows of combined sewer overflows (CSO) to marine tidal basins create stratified water quality for limited periods of time. Accurate assessment of water quality...

Hydropower: Making Its Mark in North America
To discover what plans North American hydropower producers have for their hydroelectric resources in the 1990s, Hydro Review conducted a survey of leaders in the hydro generation industry...

Digital Governor Application ? Bradley Lake Project
The Bradley Lake Project has two impulse turbines rated at 60 MW each to provide power to the Railbelt region of Alaska. Solid state digital governors are utilized to respond to system...

Deflector Synchronizing and Governing
This paper is a survey of deflector control speed govern impulse turbines for synchronization to a grid, and for isolated operation. There are several advantages to deflector control versus...

Optimal Real-Time Control of Hydroelectric Power Plant Using Dynamic Programming
In this paper, an approach of optimal real-time control of hydroelectric power plant operations is presented. The methodology is based on a dynamic programming technique where the original...

Hand Held Powerhouse Control Console or Portable Data Terminal
The Portable Data Terminal (PDT) is a very small light weight hand held computer terminal that communicates with the control system computer by radio. An operator monitors power plant...

Optimising Electric Power From a Small Scale Hydro Plant
The paper summarizes new development in electrical power generation from small scale hydro prime movers. It describes various methods of power generation such as CSCF (Constant speed constant...

Manasan Ice Control Structure Rehabilitation & Bypass Designs
Ice control works built on the Burntwood River at Manasan Falls were damaged during the 1985 spring break-up. The ice boom had broken and the lowered pond level indicated that the rockfill...

Total Quality Planning
When it comes to major unit maintenance, 'total quality results' require an investment in 'total quality planning.' The successful replacement...

Ground-Water Recharge from Streamflow Data, NW Florida
Annual base flows of streams draining Okaloosa County and adjacent areas in northwest Florida were determined through hydrograph separation and correlation techniques for purposes of evaluating...

The Effect of Channelization of R?o Puerto Nuevo on Ground-Water Levels in the San Juan Metropolitan Area, Puerto Rico
Channelization and concrete lining of the Rio Puerto Nuevo and its tributaries in the San Juan Metropolitan area has been proposed to control flooding in low lying areas adjacent to the...

A Study of a Flood Control Levee Swamp System
In an attempt to reconstruct the events of the more than 100-year 1987 New Year's Eve storm that occurred on Oahu, Hawaii, an analysis of a complicated overland flow phenomenon...

The NPUSM (Narmada) Model for Modeling Canal Flows
The NPUSM computer program was developed for the analysis of unsteady flows in canals with various types of canal structures to evaluate the Narmada Canal system in Gujarat, India. The...

The National Water-Quality Assessment (NAWQA) Program?A Basis for Water-Resource Policy Development
The concepts that are the basis for the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) program began forming in the early 1980's. By 1986,...
