Nevertheless, other possible applications exist. In particular, bed-load transport phenomena are relevant in urban drainage systems, including sewers. However, few applications of coupled two-dimensional (2D) shallow-water and bed-load transport models can be found, and their transfer from environmental applications — usually river and floodplain — into sewer applications requires some adaptation. Unlike to river systems, where there is a thick layer of sediment that constitutes a movable riverbed, sewer systems have thin layers of sediment that need to be removed, thus exposing a rigid, nonerodible surface. This problem requires careful numerical treatment to avoid generating errors and instability in the simulation. This paper deals with a numerical approach to tackle this issue in an efficient way that allows large-scale studies to be performed and provides empirical evidence that the proposed approach is accurate and applicable for sewage and channel-flushing problems.}, language = {en} } @misc{MoralesHernandezOezgenXianCaviedesVoullieme, author = {Morales-Hernandez, Mario and {\"O}zgen-Xian, Ilhan and Caviedes-Voulli{\`e}me, Daniel}, title = {Effects of microtopography across spatial scales: studying hydrological response through high-resolution shallow-water modelling}, series = {EGU General Assembly 2020, Online, 4-8 May 2020}, journal = {EGU General Assembly 2020, Online, 4-8 May 2020}, doi = {10.5194/egusphere-egu2020-10655}, language = {en} }
