Hugo's Sturctural Damage in Puerto Rico
The results of a study of the wind damages caused by Hurricane Hugo is presented. Cases involving wood structures, industrial steel buildings, multistory reinforced concrete buildings,...
Architectural Lessons Learned From Hurricane Hugo
All of us in the building design professions have learned many lessons in the last year since Hugo. My experience, as with many of us in the design profession in Charleston, has been on...
Pumping In and Pumping Out: Case Histories of Fluidized Sand Bypassing for Channels and Beachface Dewatering for Beaches
New technologies can change management of sand in coastal areas. Fluidization, pumping in additional water beyond the quicksand point, makes a 50:50 sand-water slurry that will flow down...
Dune Maintenance
Beach nourishment and stabilization may be achieved through the replacement of sand eroded from the dune. A generalized description of the physical processes and the storm protection benefits...
Port Layout Optimization for Large Bulk Carriers in a Strong Tidal Currents Site
To provide the sheltering conditions of Ponta da Madeira Terminal (TPM) in Sao Marcos Bay, in Sao Luis, Brasil, two rubble mound groins were designed and constructed according to hydraulic...
Effect of Wind on Coastal Construction in Florida
The State of Florida's tidal shoreline is 8,426 miles long. Both the east and the west coast of Florida is subjected to several coastal storms each year. The present study...
Rehabilitation of Vertical Thin-Walled Breakwater
Physical hydraulic model tests were conducted to measure wave transmission and force characteristics of a partial vertical thin-walled breakwater. Tests were run for the breakwater in...
Geological Assessment of Offshore Sand Deposits
The United States Atlantic and Gulf of Mexico continental shelf contains large numbers of surficial sand deposits. The search for sand resources for metropolitan construction and coastal...
Beach and Cliff Erosion Processes at Solana Beach, California, 1984-1990
Observations of back beach elevation changes, profiles and cliff erosion over a 7-year period from 1984-1990 provide a detailed local view of these processes and rates at a typical Southern...
Grunion Spawning Versus Beach Nourishment: Nursery or Burial Ground?
At Cabrillo Beach in San Pedro, California, a major sand renourishment project was scheduled to commence during the annual grunion spawning season, which occurs from February through August....
Rise and Intrusion of Caspian Sea Water into Mazandaran Province Coastal Lands
The Caspian sea water level was -29.13m (MSL) in 1977 and reached -27.68m in 1987. Although the rise and fall in the sea water level has been recognized as a periodic phenomenon (every...
Ocean Wave Propagation up a Narrow Channel
The results of a hydraulic model investigation of ocean wave propagation up a narrow channel are reported. Both monochromatic and random waves were used to study the wave characteristics...
Waves on Coral Reefs
In connection with hydraulic studies for development of a new harbour on the SW-corner of Male Island in the Maldives, the author took an interest in the phenomena of waves on coral reefs....
Nature-Assisted Dune Restoration
The concept of finding and placing compatible sand along the coastal shoreline for dune restoration is presented. Laboratory experimental result supporting this concept is reported. Field...
Ecological and Geomorphic Impact of the Destruction of a Coastal Sand Dune System in a Sand Spit
Two main effects of the destruction of the coastal dunes at the sand spit of Estero de Punta Banda, (B.C., Mexico) were studied comparing unaltered and altered adjacent zones, The amount...
A Comprehensive Project for the Venice Lagoon
The Venice Lagoon is undergoing a severe process of environmental decay, due to increasing pollution from urban, industrial and agricultural sources. A number of projects have been launched,...
Submarine Sand Ridges: Unique Marine Environment and Natural Resources
Submarine sand ridges are large scale depositional sandy bodies on the inner shallow water continental shelves, which are mostly distributed in the macro tide area where the mobile sandy...
NDBC's Observations in the Coastal Zone
The National Data Buoy Center (NDBC) has been collecting data from coastal buoys since 1979. Measurements, taken each hour, include wind direction, wind speed, significant wave height,...
Infragravity Waves, Longshore Currents, and Linear Sand Bar Formation
A new hypothesis regarding the role of infragravity waves in controlling the formation and offshore migration of linear (2-dimensional) sand bars is presented. The hypothesis is dependent...
Effect of Long Waves to Local Sediment Transport Rate
When irregular waves travel to the shoreline, long wave component becomes important in the surf zone. In the surf zone, sands are transported by both wave motion and turbulence due to...
