Description of hydrogeological data in SKB's database GEOTAB. Version 2

During the research and development program performed by SKB for the final disposal of spent nuclear fuel, a large quantity of geoscientific data was collected. Most of this data was stored in a database called GEOTAB. The data is organized into eight groups (subjects) as follows: - Background information. - Geological data. - Borehole geophysical measurements. - Ground surface geophysical measurements. - Hydrogeological and meteorological data. - Hydrochemical data. - Petrophysical measurements. - Tracer tests. Except for the case of borehole geophysical data, ground surface geophysical data and petrophysical data, described in the same report, the data in each group is described in a separate SKB report. The present report described data within the hydrogeological data group. The hydrogeological data groups (subject), called HYDRO, is divided into several subgroups (methods). BHEQUIPE: equipments in borehole. CONDINT: electrical conductivity in pumped water. FLOWMETE: flowmeter tests. GRWB: groundwater level registrations in boreholes. HUFZ: hydraulic unit fracture zones. HURM: hydraulic unit rock mass. HYCHEM: hydraulic test during chemical Sampling. INTER: interference tests. METEOR: meteorological and hydrological measurements. PIEZO: piezometric measurements at depths in boreholes. RECTES: recovery tests. ROCKRM: hydraulic unit rock types in the rock mass. SFHEAD: single hole falling head test. SHBUP: single hole build up test. SHSINJ: single hole steady state tests. SHTINJ: single hole transient injection tests. SHTOLD: single hole transient injections tests - old data. A method consists of one or several data tables. In each chapter a method and its data tables are described. (au)
