Surface water bodies with surveys according to the Water Framework Directive
Description
Data is provided by Hamburg surface water bodies for which evaluation events and measures are collected in accordance with the EC Water Framework Directive (EC-WRD).
For the assessment, the Water Framework Directive requires certain quality values to be achieved by 2015 in different rating classes:
— Assessment of chemistry (successed by the Institute of Hygiene and Environment, HU)
— Evaluation of biology: Flora and fauna (BSU)
— Hydromorphology, water structure quality (BSU)
Each evaluation is based on predetermined attributes. Measured values are usually combined into state values (good; means; bad). For certain attributes, there are only two values: The limit value has been met or exceeded.
The required messages to the bundle are made on certain cut-off days via a standardised XML schema and as shape files.
The water management measures describe activities that take place on certain water sections in order to improve the quality there and to meet the requirements of the Water Framework Directive.
The allocation to the waters and sections of the water is based on the master data of the topological water network (RW SEG GEOM).
The data is provided here as a WMS representation service and WFS download service. The assessments and measures under the Water Framework Directive are linked to the water body objects in the form of profile letters and csv files.
