BRADLEY F. LYLES

EDUCATION:

M.S., Hydrogeology, University of Nevada, Reno
B.A., Geology, California State University, Fresno

PROFESSIONAL INTERESTS:

Mr. Lyles' research and experience are focused on the study of ion and isotope geochemistry. Current research has included the use of geostatistics to refine groundwater gradients to further understand geochemical mixing in carbonate and alluvial aquifers of southern Nevada. Hydraulic parameters and geochemical variability have been used successfully to delineate buried geologic structures of Las Vegas Valley. Time-series spring data have been used to identify groundwater recharge characteristics.

Other research interests include the development of data acquisition systems for hydrologic studies such as the development of a water stage and chemistry data logging system in a limestone karst environment; the design and development of a hydrochemical logging tool capable of measuring temperature, electrical conductance, pH, dissolved oxygen, and bromide, consecutively; and, the development of a thermal-pulse flowmeter logging tool for measuring vertical groundwater flow in boreholes.

RESEARCH AREAS:

Hydrology of the Unsaturated Zone; Contaminant Transport; Hydrogeological Controls on Availability and Quality of Ground Water; Global Environmental Hydrology; Integrated Watershed System
