Abstract: This data shows Arterial Drainage Scheme (ADS) Channels constructed under the Arterial Drainage Acts 1945 & 1995, that OPW has a statutory obligation to maintain. These channels are either modified watercourses or constructed channels/drains to enhance the conveyance or constructed to modify the flow regime in an area. The …
Pollution Impact Potential (PIP) maps were generated separately for nitrate and phosphate to rank critical source areas (CSAs) relative to one another from diffuse agriculture for both the groundwater and surface water receptor. The PIP maps are generated by the EPA Catchment Characterisation Tool (CCT). The CCT delineates the CSAs …

This dataset represents a snapshot taken in September 2016 for the purpose of the WFD RBMP Cycle 2. WFD River Waterbodies intersecting with Designated Special Areas of Conservation (SAC) Conservation Objective Species under the EU Habitats Directive (together with the Birds Directive) - Council Directive 92/43/EE of 21st May 1992 …

This water flow network dataset is a route feature class rather than a simple polyline. The geometry is generated by merging the river lines of individual geometric network datasets. This layer contains an integrated flow network that includes known flow connections through rivers, lakes and groundwater aquifers. In places where …
These are coastal, transitional, river and lake water bodies that have a High-Status Objective under the Water Framework Directive.
Water Framework Directive (WFD) River Waterbodies (RWB) are the management and reporting units for the WFD. WFD RWB is a polyline shapefile dataset which is formed from a river routes dataset. Waterbodies are assigned types depending on their likely WFD status classification and physical and biological characteristics (typology). This is …
