Deeper groundwater bodies according to WFD (tertiary GWK)

‘Delimitation of groundwater bodies in Upper Austria; Horizons in the Sands of the Tertiary A water body is a coherent sub-unit of a river basin district to meet the environmental objectives of the Water Framework Directive (WFD). Each river basin consists of numerous water bodies. There are three horizons available in DORIS: 1. Horizon: near-surface GW bodies 2. Horizon: thermal GW Body 3. Horizon: deeper GW body»奥地利上奥地利州地下水体划分；第三纪砂层中的地下水层位 水体是流域片区内的连贯子单元，旨在满足《水框架指令》（Water Framework Directive, WFD）的环境目标。每个流域均包含多个水体。 DORIS 中共设有三类地下水层位： 1. 层位：近地表地下水体（Groundwater Body, GW） 2. 层位：地热地下水体（Groundwater Body, GW） 3. 层位：深层地下水体（Groundwater Body, GW）
