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...

Groundwater Management in the Main Aquifer of High Aswaan Dam
The High Aswaan Dam reservoir replenishes a groundwater aquifer which extends on both sides of the dam lake with variable thickness. The groundwater of this aquifer is used to irrigate...

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...

Bed Forms of Nile River
In this paper, the observed bed forms for six different reaches of the Nile River in Egypt are described. The purpose of the study is to inquire whether or not the different available...

Sediment Transport Measurements in the Nile River at Bani Mazar
Measurements of sediment transport on the Nile River were conducted at Bani Mazar (200 km South of Cairo) during high and low water stages. Bed-load and suspended-load transport rates...

Environmental Considerations in Sustainable Development and the Application of Appropriate Technology
A fundamental appropriate technology concept is that technologies, as well as the development process, must be environmentally sound. As stated by the United Nations' World...

Sedimentation Problems and Solutions: Roseires Dam and Reservoir, Sudan
Roseires Dam and reservoir are located in Sudan, Africa on the Blue Nile River. The hydropower from the reservoir provides approximately 80% of the power used in Sudan, thus having a tremendous...

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...

Effect of Manning's Roughness Coefficient in Simulating Flow Parameters in Natural Channels
Manning's roughness coefficients are presented for three of the oldest and largest irrigation canals in Egypt. The discharges ranges from 35 to 318 m3/s....

Cofferdam Rip-Rap Protection for the New Esna Barrage
A 1:60 undistorted mobile bed model of the Nile River in the vicinity of Esna Barrage was constructed at the Hydraulics and Sediment Research Institute to test rip-rap protection of the...

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...

Determination of Vertical Leakage for Nile Valley
The determination of vertical groundwater leakage is particularly important for irrigated agriculture where adequate drainage is required to prevent high water tables and related problems...

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...

The Design & Construction of Marina Martinique, S. Africa
Marina Martinique is a coastal residential marina in the eastern Cape Province of South Africa which will ultimately accommodate 730 moorings and 1100 low rise residential units, most...

Lessons from Hurricane Hugo: Recommendations for Marina Operation and Design
Hurricanes are not new to South Carolina, but with the recent development of the coast, many new and unseasoned boaters have located in the area. Since Hurricane Hazel in 1954, South Carolina...
