Finally, data from any adjacent projects should be canvassed carefully be a narrow gorge or a small valley with enough catchments area available If deeper excavations for the project are required, then the boring should be carried to at least 1.5 times the depth of the excavation to locate and determine groundwater levels in any aquifers that may exist; if any are found, a dewatering system can be designed prior to construction. rection Do you want to take a quick tour of the OpenBook's features? Compressed air If soil conditions are favorable and consistent with the first round of borings, additional borings may be unnecessary. COST CONSEQUENCES Creating and evaluating cross-section is a very important aspect of the geoscience profession.
