Outlet locations of river basins in a, the continental United States and b, Germany employed as case studies. Gray dots indicate watersheds in the study dataset (Methods; n = 41 in the United States and n = 32 in Germany). White dots represent watersheds in the test dataset (Methods; n = 252 in the United States and n = 403 in Germany). Colorbar shows 30-years annual precipitation normals (USA: 1981–2010; Germany: 1991–2020).
