“…Background elevation data from https://land.copernicus.eu/imagery-in-situ/eu-dem/eu-dem-v1-0-andderived-products. The stream network was obtained from http://www.sandre.eaufrance.fr/ Hydrological models (Gutiérrez-Jurado, Partington, Batelaan, Cook, & Shanafield, 2019;Ward, Schmadel, & Wondzell, 2018;Williamson, Agouridis, Barton, Villines, & Lant, 2015;Yu, Bond, Bunn, Xu, & Kennard, 2018), topographic data (Prancevic & Kirchner, 2019) and statistical approaches (Beaufort, Carreau, & Sauquet, 2019;Durighetto, Vingiani, Bertassello, Camporese, & Botter, 2020;González-Ferreras & Barquín, 2017;Jaeger, Sando, et al, 2019;Konrad & Rumsey, 2019;Russell, Gale, Muñoz, Dorney, & Rubino, 2015;Snelder et al, 2013) have been used to predict where streams are temporary and can be used to determine where additional data on the state of temporary streams may be most useful. However, to train and validate these models, more observations of the state of temporary streams and stream network dynamics are needed.…”
