# #Archive data from the 2018 Hydroclimatic Atlas ## #Description The Hydroclimatic Atlas describes the current and future water regime in southern Quebec in order to support the implementation of water management practices that are resilient to climate change. ## #Avertissement The 2018 version of the Atlas is now replaced by a more recent version on the website. Data from the 2018 version is archived on Data Québec for reference, for example for old reports or analyses referring to this version of the data. Any new study or analysis should use the most recent data available on [Data Quebec (Hydroclimatic Atlas 2022)] (https://www.donneesquebec.ca/recherche/dataset/atlas-hydroclimatique-2022) or on the Atlas website (www.cehq.gouv.qc.ca/atlas-hydroclimate-). ## #Liste of available data * Map of river sections from the Hydroclimatic Atlas with their attributes (available in GeoJSON and shapefile format). * CSV tables (“Magnitude...”) for each of the 28 hydrological indicators describing the __amplem__ and __direction__ for RCP4.5 and RCP8.5, for the three future horizons (see documentation for details). * CSV tables (“Projected indicator”). * CSV tables (“Projected indicator”)...”) for each of the 28 hydrological indicators detailing the flow values with their uncertainty for the historical period and the three future horizons (RCP4.5 and 8.5). See documentation for more details. * A more detailed [PDF with metadata and description] (https://www.donneesquebec.ca/recherche/dataset/atlas-hydroclimatique-2018/resource/7af10f58-75a0-4839-b9f0-2b9728cb447d) of the data.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This theme represents an indicator of the availability of summer and winter surface water. It combines a sub-indicator of the pressure of water samples from surface water, and a sub-indicator of the severity of low water levels. The indicator is calculated based on the current and future climate.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

# #Données of the 2022 Hydroclimatic Atlas ## #Description The Hydroclimatic Atlas describes the current and future water regime of southern Quebec in order to support the implementation of water management practices that are resilient to climate change. These data are from the most recent version of the [Hydroclimatic Atlas] (https://www.cehq.gouv.qc.ca/atlas-hydroclimatique). ## #Nouveautés * Improvement of the spatial resolution of the hydrographic network; * Greater spatial coverage; * Addition of the CliMEX and CORDEX-NA sets, in addition to the scenarios in the CMIP5 set; * Use of six hydrological platforms; * * Addition of indicators, especially annual ones. * Etc. ## #Liste data available * Link to the new Hydroclimatic Atlas website. * Map of the 24,604 river sections of the Hydroclimatic Atlas with their attributes, available in GeoJSON and shapefile format. To facilitate download and display, the map is divided into 11 GeoJSON files: ABIT (Abitibi and Lac Abitibi region), CND west (North Shore A and B regions), CND east (North Shore regions C, D and E), GASP (North Shore regions C, D and E), GASP (Gaspésie), MONT (Gaspesie), MONT (Montégérie), OUTM (Outaouais Upstream), OUTV (Outaouais Downstream), OUTV (Outaouais Downstream), SAGU (Saguenay), SLNO (St-Laurent Nord-Ouest), SLSO (St-Laurent Sud-Ouest), and VAUD (Vaudreuil). * The CSV tables (“Magnitude...”) for each of the 76 hydrological indicators describing the __amplement__, the __direction__ and the __dispersion__ for RCP 4.5 and RCP8.5, for the three future horizons (see the [documentation] (https://www.donneesquebec.ca/recherche/dataset/8bc217ff-d25d-4f55-a9a7-ada3df4b29a7/resource/086e3a6d-9e79-4aee-81c3-4b2343bf7996/download/metadonnees_atlas2022.pdf) for details). * The CSV tables (“Projected indicator...”) for each of the 76 hydrological indicators detailing the flow values with their uncertainty for the historical period and the three future horizons (RCP4.5 and 8.5). See the [documentation] (https://www.donneesquebec.ca/recherche/dataset/8bc217ff-d25d-4f55-a9a7-ada3df4b29a7/resource/086e3a6d-9e79-4aee-81c3-4b2343bf7996/download/metadonnees_atlas2022.pdf) for more details. * A [PDF] (https://www.donneesquebec.ca/recherche/dataset/8bc217ff-d25d-4f55-a9a7-ada3df4b29a7/resource/086e3a6d-9e79-4aee-81c3-4b2343bf7996/download/metadonnees_atlas2022.pdf) with the metadata and a more detailed description of the data. ## #Note The [2018 version data] (https://www.donneesquebec.ca/recherche/dataset/atlas-hydroclimatique-2018) is archived on Data Quebec for reference, for example for old reports or analyses referring to this version of the data.
