Special Issue Information

Dear Colleagues,

Over the last decades, we have experienced severe and disastrous consequences of opposite hydrological extremes: floods and landslides that have caused the loss of many lives, enormous damage to properties and infrastructure, and huge personal and societal costs, as well as droughts that have caused extensive damage to crops and endangered food production and the safety of water supply. How can these events be placed in a historical context, how are they related to already-experienced changes in the climate, and what can we expect within climate change scenarios in the coming decades? Do we have the tools and methods to understand the cause, predict the consequences, and, importantly, communicate these? How have we traditionally mitigated such consequences and how can new technologies be applied to mitigate and reduce the effects of extreme hydrological events in the future? Over the decades, population size and urbanization have increased significantly, and these consequences have become more severe. Have the extremes become more extreme or is it only the consequences due to other reasons that have done so? These are the core topics and questions this Special Issue will address:

  • Hydrological extremes from a historical and future perspective;
  • Tools and methods to predict and communicate the causes and consequences of hydrological extremes;
  • How prepared are we for the future, what mitigation measures are in place and are they sufficient for the future, and what new technologies can be applied?
  • How do urbanization and population growth influence the consequences of hydrological extremes?

Due to the changing climate, flash floods have been increasing recently and are expected to further increase in the future. Flash floods caused by heavy rainfall with snowmelt contribution due to sudden rises in temperature or rain-on-snow events have become common in autumn and winter in Norway. These events have caused widespread damage, closure of roads and bridges, and landslides, leading to evacuations in the affected areas. Hence, it is important to analyze such events. In this study, the rain-on-grid technique in the TELEMAC-2D hydrodynamic model was used for runoff modelling and routing using input of snowmelt, and precipitation partitioned on snow and rain was calculated via the hydrological model HBV. The results show the importance of including snowmelt for distributed runoff generation and how the rain-on-grid technique enables extracting flow hydrographs anywhere in the catchment. It is also possible to extract the flow velocities and water depth at each time step, revealing the critical locations in the catchment in terms of flooding and shear stresses. The rain-on-grid model works particularly well for single peak events, but the results indicate the need for a time-varying curve number for multiple peak flood events or the implementation of another infiltration model.
