Lotic Riparian - Digital Elevation Model (DEM) Derived

Lotic Riparian - Digital Elevation Model (DEM) Derived This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. Riparian areas consist of the lands adjacent to streams, rivers, wetlands and lakes that are strongly influenced by the presence of water. They are often distinct from the surrounding landscape as the vegetation growth is very lush. These areas form a transition between dry land and open water and are characterized by the presence of hydrophilic vegetation and specific soil types. Riparian areas are usually very productive in terms of biomass and form critical wildlife habitat. These areas often have standing water and are subjected to periodic flooding when high water levels fill the stream channel to the top of the bank. The term 'riparian' is derived from the Latin word for river bank. Riparian areas provide valuable food, shelter and travel corridors as well as close proximity to a water source for wildlife and livestock. These zones are often densely vegetated and serve as stabilization against the erosive forces associated with lotic systems. Riparian areas provide filtration for surface runoff from the surrounding land and protect the water quality of flowing streams. They trap sediment and reduce the velocity of stream flow, thus reducing erosion in downstream areas. These areas provide detritus to their associated aquatic systems as well as a moderating effect on surface temperatures. This riparian mapping project is intended to provide a geodatabase feature class of potential riparian areas associated with lotic features (streams and rivers) using the hydrologically corrected provincial digital elevation model as a base. Potential riparian areas associated with lentic features (wetlands and lakes) are not being captured at this time but wide rivers and lakes with flow through must be taken into consideration in order to give a more accurate representation of riparian areas. Isolated lakes are not included and no allowance for cultivated lands has been made. 2024-09-27 Government of Alberta AEP.GDAMetadata@gov.ab.ca Nature and EnvironmentALBERTAAQUATICBIOTADRAINAGEECOLOGYFLOODHABITATINLANDWATERSLAIPRLOWER-ATHABASCA-INTEGRATED-PLANNING-REGIONLOWER-PEACE-INTEGRATED-PLANNING-REGIONLPIPRNORTH-SASKATCHEWAN-INTEGRATED-PLANNING-REGIONNSIPRRDIPRRED-DEER-INTEGRATED-PLANNING-REGIONRIPARIANRIVERSHORELINESOUTH-SASKATCHEWAN-INTEGRATED-PLANNING-REGIONSSIPRSTREAMUAIPRUPIPRUPPER-ATHABASCA-INTEGRATED-PLANNING-REGIONUPPER-PEACE-INTEGRATED-PLANNING-REGIONWETLANDGovernment information Lotic Riparian - Digital Elevation Model (DEM) Derived - (HTML)HTML https://geodiscover.alberta.ca/geoportal/rest/metadata/item/df7cc4a1a6664aab999c8b45b41fbed2/html Original metadata (https://open.alberta.ca/opendata)HTML https://open.alberta.ca/opendata/c45106e3-d9a6-48b9-a280-c772e77dfc7a Lotic Riparian - Digital Elevation Model (DEM) Derived - (XML)XML https://geodiscover.alberta.ca/geoportal/rest/metadata/item/df7cc4a1a6664aab999c8b45b41fbed2/xml Lotic Riparian - Digital Elevation Model (DEM) Derived (From Alberta Geodiscorver Portal metadata)ZIP https://extranet.gov.ab.ca/srd/geodiscover/srd_pub/biota/Riparian/LoticRiparianDigitalElevationModelDerived.zip
