The\r\nspatial variability of rainfall can affect streamflow and sediment transport\r\nvolumes and peaks. Yet, the effect of climate change on the small-scale\r\nspatial structure of heavy rainfall and subsequent impacts on hydrology and\r\ngeomorphology remain largely unexplored. In this study, the sensitivity of\r\nthe hydro-morphological response to heavy rainfall at the small-scale\r\nresolution of minutes and hundreds of metres was investigated. A numerical\r\nexperiment was conducted in which synthetic rainfall fields representing\r\nheavy rainfall events of two types, stratiform and convective, were\r\nsimulated using a space-time rainfall generator model. The rainfall fields\r\nwere modified to follow different spatial rainfall scenarios associated\r\nwith increasing temperatures and used as inputs into a landscape evolution\r\nmodel. The experiment was conducted over a complex topography, a medium-sized\r\n(477 km2) Alpine catchment in central Switzerland. It was found that\r\nthe responses of the streamflow and sediment yields are highly sensitive to\r\nchanges in total rainfall volume and to a lesser extent to changes in local\r\npeak rainfall intensities. The results highlight that the morphological\r\ncomponents are more sensitive to changes in rainfall spatial structure in\r\ncomparison to the hydrological components. The hydro-morphological features\r\nwere found to respond more to convective rainfall than stratiform rainfall\r\nbecause of localized runoff and erosion production. It is further shown that\r\nassuming heavy rainfall to intensify with increasing temperatures without\r\nintroducing changes in the rainfall spatial structure might lead to\r\noverestimation of future climate impacts on basin hydro-morphology."}],"has_accepted_license":"1","OA_type":"gold","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"intvolume":"         8","month":"01","main_file_link":[{"url":"https://doi.org/10.5194/esurf-8-17-2020","open_access":"1"}],"date_created":"2026-07-27T12:30:24Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","_id":"22558","day":"17","quality_controlled":"1","oa":1,"DOAJ_listed":"1","OA_place":"publisher","year":"2020","citation":{"mla":"Peleg, Nadav, et al. “Temperature Effects on the Spatial Structure of Heavy Rainfall Modify Catchment Hydro-Morphological Response.” <i>Earth Surface Dynamics</i>, vol. 8, no. 1, Copernicus Publications, 2020, pp. 17–36, doi:<a href=\"https://doi.org/10.5194/esurf-8-17-2020\">10.5194/esurf-8-17-2020</a>.","short":"N.
