  text: "Heavy rainfall is expected to intensify with increasing\r\ntemperatures,
    which will likely affect rainfall spatial characteristics. 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."
