The primary variables considered in most of these works include terrain models, lithology, river networks and land use. While several recent studies include average annual rainfall and\/or temperature, other meteorological information such as snow accumulation and short-term intense rain events that may influence the hydrology of the area under investigation have not been considered. Notably, in Canada, most inland flooding occurs during the freshet, due to the melting of an accumulated snowpack coupled with heavy rainfall. Therefore, in this study the impact of several climate variables along with various hydro-geomorphological (HG) variables were tested to determine the impact of their inclusion. Three tests were run: only HG variables, the addition of annual average temperature and precipitation (HG-PT), and the inclusion of six other meteorological datasets (HG-8M) on five study areas across Canada. In HG-PT, both precipitation and temperature were selected as important in every study area, while in HG-8M a minimum of three meteorological datasets were considered important in each study area. Notably, as the meteorological variables were added, many of the initial HG variables were dropped from the selection set. The accuracy, F1, true skill and Area Under the Curve (AUC) were marginally improved when the meteorological data was added to the a parallel random forest algorithm (parRF). When the model is applied to new data, the estimated accuracy of the prediction is higher in HG-8M, indicating that inclusion of relevant, local meteorological datasets improves the result.<\/jats:p>","DOI":"10.3390\/rs14071656","type":"journal-article","created":{"date-parts":[[2022,3,30]],"date-time":"2022-03-30T21:28:39Z","timestamp":1648675719000},"page":"1656","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Accessing the Impact of Meteorological Variables on Machine Learning Flood Susceptibility Mapping"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6439-3339","authenticated-orcid":false,"given":"Heather","family":"McGrath","sequence":"first","affiliation":[{"name":"Natural Resources Canada, Ottawa, ON K1S 5K2, Canada"}]},{"given":"Piper Nora","family":"Gohl","sequence":"additional","affiliation":[{"name":"Natural Resources Canada, Ottawa, ON K1S 5K2, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,30]]},"reference":[{"key":"ref_1","unstructured":"Natural Resources Canada and Public Safety Canada (2018).
