Thomas J Mack, PG
Tom Mack has been a hydrogeologist with the USGS since 1983.
Tom has conducted numerous hydrologic investigations from site-specific contaminant studies to regional-scale resource assessments in the Northeastern U.S., Afghanistan, Africa, Emirates, and Madagascar. He specializes in regional groundwater resource assessments in valley-fill and fractured-bedrock settings. Other areas of expertise include: remotely-sensed data and groundwater flow modeling in regional water-availability investigations, analysis of GIS data for regional water and mineral resource evaluation, surface and borehole geophysical techniques, and borehole drilling.

Technique for estimation of streamflow statistics in mineral areas of interest in Afghanistan
A technique for estimating streamflow statistics at ungaged stream sites in areas of mineral interest in Afghanistan using drainage-area-ratio relations of historical streamflow data was developed and is documented in this report. The technique can be used to estimate the following streamflow statistics at ungaged sites: (1) 7-day low flow with a 10-year recurrence interval, (2) 7-day low flow wit
