Hydrography (HY) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

Vatnsföll eru gjarnan flokkuð í þrjá flokka, dragár, lindár og jökulár eftir rennslisháttum. Mörg eru vatnsföllin þó af blönduðum uppruna vegna margbreytileika vatnasviða þeirra. Gagnasettið sýnir greiningu vatnasvæða í vatnafarsflokka, eftir því hvernig svæðið bregst við úrkomu og miðlar henni, og rennslisháttum vatnsfalla sem eiga uppruna sinn á viðkomandi svæði.

Stream Centreline Network derived from 1:50,000 scale mapping. Each stream channel is represented by one or more line segments. Based on the 1:50,000 scale Canadian National Topographic Series of Maps.

Polygon features represent developed ground water aquifers in BC (that have been mapped). Most aquifer boundaries are delineated based on geology, hydrology and topographic information. Some aquifer boundaries stop at the border of BC mapsheet boundaries due to resource or data constraints at the time of mapping.

This ArcGIS Online application displays the hydrometric stations and accompanying drainage areas analyzed as part of Bulletin 2020-1-RFFA described below. A frequency analysis was conducted on Annual Maximum Series (AMS) streamflow data collected at Water Survey of Canada (WSC) and United States Geological Survey (USGS) hydrometric gauge stations that met the following criteria for inclusion in the Bulletin 2020-1-RFFA study: at least 10 years or data (with 350 or more days of observations) above the low outlier threshold; less than 20% (by basin drainage area) regulation; a corresponding basin polygon dataset (either supplied or delineated) with an area <15% different than the basin area reported by WSC or USGS; full metadata coverage for the basin (e.g. mean annual precipitation, elevation, etc.); and 1-, 3-, 5-, and -10 day distribution fits that did not overlap for any Average Recurrence Interval’s (ARI) above 2 years. The analysis was conducted by Northwest Hydraulic Consultants and RTI International Inc. for the Water Management Branch of FLNRORD. The geographic area of the dataset is shown in Bulletin 2020-1-RFFA and consists of all of British Columbia and selected watersheds around the perimeter of the province. There are 3 datasets within this project consisting of: • Hydrometric station locations of the stations that were analyzed as part of the study. • The drainage areas of the respective hydrometric stations that were analyzed. • The BC Hydrologic Zones that were extended outside of BC.

Útlínur dregnar eftir uppréttum loftmyndum frá Loftmyndum ehf. og einnig eftir Landsat 8 gervihnattamyndum á nokkrum stöðum.

Útlínur byggðar á kortlagningu á jökulgarða og annarra landforma sem jöklar skilja eftir. Einnig er byggt á rituðum heimildum, frásögnum heimamanna og ferðafólks, ljósmyndum og öðrum tiltækum gögnum. Um er að ræða niðurstöður margra rannsóknarhópa. Flestir jöklar náðu hámarksútbreiðslu í kringum 1890, en meðal undantekninga frá því er Drangajökull sem náði mestri útbreiðslu um miðja 19. öld.

The "Effective Drainage Area of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing polygon features representing the areas of the Agriculture and Agri-Food Canada's (AAFC) Watersheds Project that could, for the entire project areas, be expected to contribute to surface runoff under average runoff conditions.
