An empirical method for estimating travel times for wet volcanic mass flows
Thomas C. Pierson
1998, Bulletin of Volcanology (60) 98-109
Travel times for wet volcanic mass flows (debris avalanches and lahars) can be forecast as a function of distance from source when the approximate flow rate (peak discharge near the source) can be estimated beforehand. The near-source flow rate is primarily a function of initial flow volume, which should be...

Kathleen A. McCarthy, Michael R. Lilly, Joan F. Braddock, Larry D. Hinzman
1998, Open-File Report 98-198
Natural attenuation processes include biological degradation, by which microorganisms break down contaminants into simpler product compounds; adsorption of contaminants to soil particles, which decreases the mass of contaminants dissolved in ground water; and dispersion, which decreases dissolved contaminant concentrations through dilution. The primary objectives of this study are to (1)...
