REGIS II.1 - 02.3- Boxtel Formation - Boxtel Liempde clay1

REGIS stands for REgionaal Geohydrologisch InformatieSysteem, which is the National hydro-geological model for the Netherlands. Version II.1 is an extension and revision of the hydro-geological model version II.0 (REGIS II). REGIS has been developed by TNO, the Geological Survey of the Netherlands in cooperation with RIZA (the national water office) and the Provincial authorities. The hydro-geological model is a digital model of the upper part of the Dutch subsurface to a depth of approximately 500 meters. Using ESRI grids and shapefiles, the model shows the depth, thickness and hydraulic properties of hydro-geological units as well as the location of faults. A hydro-geological unit is a unit defined using texture, structure and soil type having (more or less) uniform hydrogeological properties bounded by facies-layers, erosion boundaries and faults. The hydrogeological model is based on the Digital Geological Model (DGM) and the shallow subsurface lithostratigraphical Nomenclature version 1.0 which is available through www.dinoloket.nlREGIS即区域水文地质信息系统（Regionaal Geohydrologisch InformatieSysteem），为荷兰国家水文地质模型。其II.1版本是对水文地质模型II.0版（REGIS II）的扩展与修订。REGIS由荷兰地质调查局TNO联合RIZA（国家水利办公室）及各省级主管部门共同开发完成。该水文地质模型是荷兰地下约500米深度浅层的数字化模型，采用ESRI栅格（ESRI grids）与形状文件（shapefiles）格式，可呈现水文地质单元的埋深、厚度、水力特性，以及断层的分布位置。水文地质单元指以岩性、结构与土壤类型为划分依据的单元，其水文地质特性大致均一，以相层、侵蚀边界及断层作为边界范围。本模型基于数字地质模型（Digital Geological Model, DGM）与浅层地下岩石地层命名法1.0版，相关数据可通过网站www.dinoloket.nl获取。
