Water Flow Network

Category: Environment

Openness rating:

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 network is depicted flowing through lakes or through underground channels, the flow channels are schematic only, and do not represent the precise location of these flow channels. The appropriate Geological Survey Ireland data sets should be consulted where underground flows or connections are known or suspected.

Provenance information The geometry of the rivers were originally generated based on the OSi 50k raster mapping, but has been updated over time as updated information has arisen from local surveys. The associated attribute data comes from a variety of sources, e.g. waterbody codes from the individual waterbody datasets. River orders are generated automatically through EPA tools using the Strahler method.
