Characteristic of the Yellow River Delta
The yellow river delta is a most unstable delta in the world. The river burst its lowstream bank 1500 times during the last 3000 years, 26 large shifting of the channel as well. The river...
Evolution of the Santee/Pee Dee Delta Complex, South Carolina, USA
The Santee/Pee Dee delta is located on the north-central portion of the lower coastal plain physiographic province of south carolina, USA, which is underlain by pleistocene strand plain...
Global Sea Level in the Past and Future Century
During the past 150 years sea level may have risen globally by, at the most, 1.1 mm/year from about 1850 to 1930-1940. There is no straightforward relation between climate and sea level....
Louisiana Cheniers: Clues to Mississippi Delta History
The cheniers of southern Louisiana have map differences, deeding differences, and granulometric differences that distinguish them from swash-built beach ridges and from dune ridges. Instead,...
Preliminary Study on Impacts of Sea Level Rise and Response Strategies in Japan
This paper presents the outline of the study carried out by a Japanese committee on the impacts of and response options to the anticipated sea level rise and climate change induced by...
Design Manual for Artificial Reefs
Artificial reefs are wave-breaking structures artificially constructed from rubble to mimic the wave-control functions of coral reefs. Since these structures are located below sea level,...
Change of Estuarine Processes Due to Sea Level Rise and Navigation Channel Improvement
To investigate the relationship between the improvement of navigation channels and the change of estuarine environment under various sea level rise scenarios, numerical study was performed...
Lake-Level Declines in Karst Lake During Droughts
Lake-level declines in Brooklyn Lake, a karst lake in north-central Florida, have been investigated. Below average rainfall, vertical leakage to the underlying aquifer system, declining...
Real-Time Forecast and Its Use for Bradley Lake Project
A forecast model was developed to assist the project operator to make a realistic prediction of lake inflow and to optimize the water usage in Bradley Lake which has an active storage...
Sustained Yield of the Provo Groundwater Basin
The sustained yield of the Provo Groundwater Basin has been determined by a correlation analysis of the change in groundwater levels with the April-October stream flow at the mouth of...
SCS Methods for Determining Irrigation Water Requirements
Technical Release No. 21 (USDA-SCS, 1970) has been used in the U.S. and around the world to design and manage irrigation projects. However, many advancements in predicting crop water use...
Designing Self-Cleaning Wet Wells for Wastewater Pumping
Guidelines for the design of self-cleaning wet wells for variable speed pumps are given. The progress of research on the design of wet wells for constant speed pumps, including submersible...
Removal of Tidal Fluctuations from Pumping Test Data
A simple technique for removing tidal fluctuations from drawdown data was examined. This technique relied simply upon transforming measured surface water level data to fit the pretest...
Annual Oscillation of Mean Monthly Water Levels at U.S. Ports
The annual variation in water level is not widely recognized among engineers. It could effect the selection of design ship channel depth or marina channel dredging, and tidal wetland creation...
Water-Level, Velocity, and Dye Measurements in the Chicago Tunnels
On April 13, 1992, a section of a 100-year-old underground freight tunnel in downtown Chicago, Illinois was breached where the tunnel crosses under the Chicago River, about 15 meters below...
Reliability Analysis of Levee System of a River
The levee height is determined by the summation between computed water level and an assumed freeboard. The water level is computed by given discharge in the steady conditions. Therefore,...
Shifts in Solute Transport Direction Induced by Transient Flow
Traditionally, solute transport projections have focussed on the long-term, steady state conditions expected to prevail in a groundwater system. However, transient effects may often dominate...
Egypt's Real-Time Water Management
The challenge and complexity of efficiently managing the distribution of the 55 billion m that Egypt draws from the Nile every year has prompted the country's Ministry of...
Remote Automated Wave and Water Level Monitoring System Deployed at Agat Harbor, Guam
Agat Harbor, Guam is a small boat harbor excavated from a coral reef flat and protected by a detached breakwater. An automated monitoring system was designed and installed to observe wave...
Two-Dimensional Circulation Modeling of the Pamlico River Estuary, North Carolina
A two dimensional, vertically averaged, unsteady flow model was applied to a 50- kilometer reach of the Pamlico River estuary, North Carolina. The model computational grid, which consists...
