Relationship Between Lysimeter Area and Evapotranspiration (ET)
The lysimeter is an important instrument for measuring evapotranspiration (ET) of crops. It is widely used in the irrigation and drainage experimental stations in China. However, the areas...
Adopted Drip Irrigation Technology for Developing Countries
Two low cost drip irrigation systems are presented. Even though the uniformity of these systems is not as high as the conventional drip systems, the initial and operating costs of the...
Hydrologic Impact of Reservoir Filling on a Fractured Crystalline-Rock Aquifer
A study of flow in and recharge to fractured rock has been initiated in conjunction with the construction and filling of a pumped-storage reservoir for a hydropower plant in the Blue Ridge...
Use of Stable Isotopes, Tritium, Soluble Salts, and Redox-Sensitive Elements to Distinguish Ground Water from Irrigation Water in the Salton Sea Basin
Evaporative concentration of irrigation water diverted from the Colorado River to the Salton Sea basin for several decades has produced an overlying system (that includes drainwater and...
Ground Water Impacts from Irrigated Ridge-Tillage
The Northern Cornbelt Sand Plain Project is a cooperative research effort between the State Agricultural Experiment Stations, USDA/Agricultural Research Service and U.S. Geological Survey...
Terrain Conductivity to Define Groundwater Pollution
Electromagnetic terrain conductivity surveys were conducted at four animal waste lagoon sites in South Carolina in an effort to delineate groundwater contamination from animal waste lagoon...
Potential Effects of Global Climate Change on the Central and Southern Florida Project
The possible impacts of some potential climate change effects such as sea level rise, changes in tropical cyclone intensity and frequency, and changes in precipitation and temperature...
Numerical Model Development for Oil Spill Dispersion into the Marine Environment
A 3-D oil spill model was developed to study the behaviour of heavy spilled oil in the sea. The model could describe the behaviour on the spilled oil on the sea surface, throughout the...
Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
Coastal Watershed Unit Hydrographs and Methods
The results of a study to determine unit hydrograph peak rate factors for South Carolina coastal watersheds are summarized and compared with traditional values. An extension to the SCS...
Construction Inspection in South Carolina
The paper will discuss the experience of the South Carolina Department of Transportation in the use of consulting engineering firms on bridge construction projects. A review of the current...
Hurricane Hugo One Year Later
Hurricane Hugo, which made landfall on September 21, 1989, was the first serious storm to cross the South Carolina coast in over 30 years. During this period, the coastal areas had grown...
The Enhancement of Air-Sea Gas Exchange by Oceanic Whitecapping
The hypothesis that oceanic whitecaps and the accompanying buoyant bubble plumes greatly enhance the air-sea transfer coefficient of gases subject to liquid phase control has recently...
Oceanic CO2 Uptake and Future Atmospheric CO2 Concentrations
The global pattern of water column inventories of bomb-produced 14C suggests that an upwelling of bomb 14C-free...

Design of Substation Foundations for Liquefaction
When substation foundations penetrate liquefiable strata within risk prone seismic regions, the potential loss of support must be evaluated with state-of-the-art methods to determine foundation...
Automatic Vehicle Classification System
China has recently completed a number of freeways, all of which were financed in part by the Ministry of Communications and local governments and in part by loans from the World Bank,...
Development of Marina Facilities on the Southern California Coast
The Southern California coastal region has developed recreational boating facilities through the use of existing bays, creation of new inland water areas and the construction of small...
Structural Investigation of Marina Del Rey Seawall
The Marina del Rey Seawall was constructed by various contractors between 1959 and 1961. It is composed of 660 panels totaling 39,600 linear feet. The seawall configuration is a type normally...
