Canada1Water Classification of the National Hydro Network: Stream Order and Graph Refinement

A vector representation of stream networks is a crucial dataset for the modelling the surface water and groundwater components of the hydrologic cycle. For many usages a crucial attribute of the drainage network is a digital topology and hierarchal stream order attribute (e.g., Strahler stream order). In Canada jurisdictional stream networks are available for the provinces and territories and nationally for Canada in the National Hydrological Network (NHN) dataset. Unfortunately, the NHN data lacks the same topological and attribute information that is available for numerous provinces due to standardization for the entire country. For Canada1Water it was also necessary to have a harmonized dataset with the United States, for both the southern transboundary watersheds and the Alaskan watersheds. This report documents the processes completed to upgrade the topological and graph network support for NHN and provide continuous connectivity with US datasets. It also highlights and corrects a number of stream density and stream order issues that occur within Canada across provincial and territorial borders and NTS tiles. All vector processing was completed in RivEX software extension for ArcMap. Following complete topological correction stream classification was assigned and a table of the node graph network developed. Additional work was then completed to normalize stream density particularly amongst low-order streams between British Columbia and the Yukon and amongst local NTS tiles in Quebec and Ontario. Corrected NHN Strahler stream order assignment was validated against a number of provincial and watershed datasets, all of which already have Strahler stream order attributed. These datasets are the same underlying digitized vector data, so there are no differences in node or polyline positions. Strahler stream order assignment validation was only done by visual comparison as due to differences in vector segments a statistical comparison is complicated. The transboundary integrated C1W stream network with complete classification provides a seamless national dataset to support transdisciplinary studies (fisheries, wildlife, health, pesticide and nutrient issues, mining impact, ecosystem restoration, numeric modelling) that involve a knowledge of stream distribution and ranking.

Use limitation

Please refer to the license information of this individual dataset, or contact that organization or individual if you are unsure of your rights regarding redistribution, use, or license information of this particular dataset.

This dataset is provided "as is" without warranty of any kind, either express or implied. The creators and distributors of this dataset shall not be held liable for any consequences arising from its use. The Canada1Water Stream Network has been developed with extensive efforts to ensure its accuracy, reliability, and utility for research, planning, and decision-making. It improves upon the original GeoBase National Hydro Network (NHN) Network Linear Flow by correcting disconnected, duplicate, intersecting polylines and in some instances, re-assigned the correct flow direction. However, it is important to note that such minor errors may persist within the released dataset. Users should also review the original GeoBase National Hydro Network Data Product and Specifications Distribution Profile Edition 1.1 for potential errors in the dataset.

Minor errors may arise to either original NHN stream geometry or be introduced during joining of the larger data set parts processed in RivEX. It should be noted by the user that small errors in stream continuity may cause down-stream errors in Strahler stream order assignment. Errors identified or reported will be addressed and corrected in future dataset version releases.

List of known or identified errors (no particular order);

1. Canada1Water Model Atlantic and NHN DATASETNAM 0220001 and 0220002 along the Ottawa river includes duplicate streamlines, one set for Ontario and another for Quebec. As such, there are different Strahler Stream Orders assigned to the Ottawa river. If a single streamline is required by the user, it is recommended that the duplicate streamlines are merged into a single streamline, and the higher Strahler Stream Order of the two segments should be used.

2.Canada1Water Model Arctic and NHN DATASETNAM 10RC000, there is a missing connection from the Hayes River to the Back River. Reprocessing of Strahler Stream Order using 10RC001 and 10RC002 is needed.
