These data vectors are digitized from field maps created by Dr. József Tóth during his 1964 to 1969 fieldwork. Dr. Tóth is a distinguished hydrogeologist who developed and published his landmark "Unit Basin" theory of steady state flow leading to the fundamental concept in hydrogeology known as "Tothian flow system theory". His contributions to hydrogeology turned the Research Council of Alberta, and subsequently the University of Alberta, into internationally renowned institutions for hydrogeological research.
Within this shapefile there are three regional lines which run parallel to dip in the Alberta basin. These lines are the boundaries used by Dr. Tóth to restrict his groundwater field investigations. There are also vectors which he has highlighted as areas of recharge and discharge that relate to some of the sites in Alberta Geological Survey report INF 143 report, but are not directly referenced. There are a few vectors in the Wainwright mapsheet which were not labeled or referenced in the report so they were omitted. The data are in ESRI shapefile format.
