Abstract: This data shows the embankments forming part of Drainage Districts. Embankments are walls of soil or sods that were constructed to protect low lying ground from flooding (not properties). Drains and sluices or pumps were also provided to take away rainwater that fell behind the embankments. Drainage Districts were …
Abstract: This data shows the land that was drained as part of the Drainage District. The original maps also identified other land owned by the same landowner so as to calculate the appropriate charge for maintenance. Drainage Districts were carried out by the Commissioners of Public Works under a number …
Abstract: This data shows the watercourses forming part of Drainage Districts. Drainage Districts were carried out by the Commissioners of Public Works under a number of drainage and navigation acts from 1842 to the 1930s to improve land for agriculture and to mitigate flooding. Channels and lakes were deepened and …
Abstract: This data shows Land Commision (LC) Benefiting Areas associated with the works carried out by landowners typically in the 19th century, that individual landowners have a responsibility to maintain. The benefited lands identifies land that was drained as part of the schemes.Purpose: This data has been developed to identify …
Abstract: This data shows Land Commision (LC) Embankments constructed by landowners typically in the 19th century, that individual land owners have a responsibility to maintain. These are man made raised structures of natural materials, constructed to protect low lying ground from flooding (not properties).Purpose: This data has been developed to …
Abstract: This data shows Arterial Drainage Scheme (ADS) Benefiting Areas associated with the schemes constructed under the Arterial Drainage Acts 1945 & 1995, that OPW have a statutory obligation to maintain. The benefited lands identifies land that was drained as part of the Arterial Drainage Schemes, which typically was performed …
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 …
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 …
The EU Water Framework Directive (2000/60/EC) (WFD) establishes a framework for the protection, improvement and management of surface waters and groundwaters. The Subcatchment dataset is built on clusters of river water body polygons and are entirely contained within the Catchment polygons dataset. All Subcatchments are represented as polygons.
Significant pressures have been identified for waterbodies that are At Risk of not meeting their water quality objectives under the Water Framework Directive. While there are a multitude of pressures in every waterbody, the significant pressures are those pressures which need to be addressed in order to improve water quality. …
