@book{welby_gowan_1998, title={A Paradox of power: Voices of warning and reason in the geosciences}, ISBN={0813741122}, DOI={10.1130/reg12}, abstractNote={The 13 papers in this volume illustrate issues and opportunities confronting geologists as they bring their knowledge and understanding to bear in matters related to public health and welfare. Public decisions and decision-making processes in the face of geologic complexity and uncertainty are the subject of the first group of papers. In the second group, several “voice of warning” papers illustrate the use of geologic knowledge and research to warn the public of health hazards derived from geologic materials and processes. A third group of papers, in the “voice of reason” section, describes use of geologic knowledge to help lower the costs of mitigation and avoidance of geologic hazards. Finally, ethical and philosophical questions confronting geoscientists are discussed and issues of “truth” as related to the legal process and questions about the adequacy of information in making decisions about long-term radioactive waste disposal are discussed.}, publisher={Boulder, Colo.: Geological Society of America}, author={Welby, C.

 @article{welby_1992, title={Field investigation of hydraulic conductivity in saprolitic materials. Comparisons of methods and techniques}, volume={29}, DOI={10.2113/gseegeosci.xxix.2.119}, abstractNote={Slug and bailing tests were made on shallow monitoring wells constructed in saprolite at two sites in the North Carolina Piedmont. Calculations for hydraulic conductivity were made using several common methods, and the hydraulic conductivity obtained from the same data depended upon the calculation method used. For bailing tests, the Bouwer-Rice method provided the most consistent result internally, but no one method proved “best” for the slug tests. Bouwer-Rice calculations for both slug and bail tests gave consistently lower conductivities than other methods. Caution should be used in applying conductivities obtained from the Hvorslev method because only a single point value is obtained. It is recommended that several methods of calculating hydraulic conductivity be employed and that the ranges of values be examined and compared prior to choice of a single value for use in any remediation work. The geometric mean of the ranges of values is thought to be best for comparison between methods.}, number={2}, journal={Bulletin (Association of Engineering Geologists)}, author={Welby, C.
