Connectivity relates to the coupling of landforms (e.g. hillslopes and channels) and the transfer of water and sediment between them. The aim of this study is to understand and quantify the relation between landscape complexity and catchment connectivity. The AA. hypothesize that connectivity decreases with increasing landscape morphological complexity. To quantify the connectivity–complexity relationship virtual digital elevation models (DEMs) with distinct morphologies were used as inputs into the landscape evolution model LAPSUS to simulate the sediment connectivity of each landscape. Additionally, the hypothesis was tested on 6 common real DEMs with widely different morphologies. Finally, the effects of different rainfall time series on catchment response were explored. Simulation results confirm the hypothesis and quantify the non-linear relation. Awareness of the differences in the behaviour and response of different morphologies to catchment processes provides information for the effective management of landscapes and ecosystems through efficiently designed soil and water conservation measures
