Schroeder, W L; Rybel, V W and Cochran, L (1986) Dewatering for opal springs powerhouse excavation. Journal of Construction Engineering and Management, 112(3), pp. 440-451. ISSN 0733-9364
Abstract
Planning and execution of dewatering for a deep excavation in coarse alluvium containing cobbles and boulders are discussed. A deep well dewatering system was installed and had to be supplemented with extensive sumping due to inflow from large natural springs, and seepage through a rock fill river diversion embankment. The value of a flexible dewatering plan and provision for backup power are illustrated. Important details of well design are provided. Good engineering, in the form of pumping tests, and design that considers construction requirements are shown to be important contributors to dewatering success.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
