Loading picture...... Drilling and Aquifer Testing in the Northern Batinah, Sultanate of Oman. November 2006.

The objective of this Project were to investigate the hydrogeology of the Northern Batinah (18 catchments).

This report includes a description of the data that was collated during this Project, borehole designs, the litho-stratigraphy cut by each borehole, analysis of surface and downhole geophysics, the dimensions of the coastal aquifers and their hydraulic characteristics, the depth and geology of the bedrock, and details of the hydrogeology and water resource of each catchment. The sustainable yield of each catchment is calculated and priority development areas are identified.

Loading picture...... Drilling and Aquifer Testing in the Northern Al Massarat, Sultanate of Oman. August 2006.

The objective of this Project was to locate and access the development potential of shallow and deep aquifers in the lower part of five catchments (Wadis Ajran, Saifah, Sharri, Al Fatah and Dank).

This report details all the activities undertaken during the Project. It includes a description of the data that was collated, details of the borehole designs, information on the lithological and stratigraphic units cut by each borehole, a description of the downhole geophysics, and details of the hydrogeological and water resource interpretations. The sustainable yield of each catchment is calculated and priority development areas are identified.

Groundwater Assessment of the Balkh & Khulm Watersheds, Afghanistan (pdf file, 6.69 MB). August 2005.

This report provides a preliminary assessment of the groundwater resources in the lower sections of the Balkh and Khulm Watersheds for an ADB Emergency Infrastructure, Rehabilitation and Reconstruction Project. Existing borehole data (water levels and water quality) were collated onto GIS-linked databases, historic hand-drawn USSR maps were geo-referenced and the hydrogeology of the area was reviewed and examined with the aid of GIS generated maps. Plans, tender documents and cost estimates were then prepared for a well inventory, a surface geophysical survey (resistivity imaging and TDEM soundings) and a drilling and aquifer testing program.

 

Drilling and Aquifer Testing in the Western Al Wusta Desert of the Sultanate of Oman. June 2005.

The objective of this Project was to delineate and quantify fresh and useable brackish water resources, and determine locations for potential wellfields near Oman's western border. Drilling targets were aquifers located in the Tertiary-aged Dammam, Rus and Umm er Radhuma Formations (UER). Overflowing artesian conditions in the UER provided challenging drilling conditions. Formations, aquifers and thief zones were identified with the aid of foraminifera, lithological descriptions and downhole geophysics.

This report includes a description of the logistical problems that were encountered, background information on the Project Area, the litho-stratigraphy cut by each borehole, interpretations of the downhole geophysics, and hydrogeological and water resource interpretations. Potential wellfield areas are identified and an assessment is made of their sustainable yields.

Hydrology of the Okavango Delta, Botswana. July 2003.

This study provides an analysis of surface inflows, outflows and recharge patterns in different parts the Okavango and the likely impact of these on wellfields being planned for Maun and associated settlements (Maun Groundwater Development Project, Phase-2).

Data availability, the climate, rainfall patterns, and hydrology of the Okavango Delta and Project Area are described. Detailed river flow and frequency analyses are presented for river-gauging stations located at Mohembo and Boro Junction. River flows in Kunyere and Dipshiping are also described.
