Comparison of two hydrodynamic models for their rain-on-grid technique to simulate flash floods in steep catchment
Godara, Nitesh; Bruland, Oddbjørn; Alfredsen, Knut Tore (Journal article; Peer reviewed, 2024)In this study, two hydrodynamic models, TELEMAC-2D and HEC-RAS 2D, were compared for their Rain-on-Grid (RoG) technique with a particular focus on runoff generation processes in a small and steep catchment. Curve number ... -
Hydrodynamic rainfall-runoff modelling for flash floods in small and steep catchments
Godara, Nitesh (Doctoral theses at NTNU;2024:261, Doctoral thesis, 2024)Global warming and climate change lead to more frequent and extreme weather events. These include sudden and intense rainfall and rising temperatures which cause flash floods. In steep terrains, flash floods with high-flow ... -
Modelling Flash Floods Driven by Rain-on-Snow Events Using Rain-on-Grid Technique in the Hydrodynamic Model TELEMAC-2D
Godara, Nitesh; Bruland, Oddbjørn; Alfredsen, Knut Tore (Peer reviewed; Journal article, 2023)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 ... -

Simulation of flash flood peaks in a small and steep catchment using rain-on-grid technique
Godara, Nitesh; Bruland, Oddbjørn; Alfredsen, Knut Tore (Peer reviewed; Journal article, 2023)The frequency of extreme events is increasing as the consequences of climate change. In steep terrains, flash floods with high-flow velocities induce erosion and sedimentation with potentially disastrous changes of flood ...
