Nitesh Godara's first PhD paper, rain on grid modelling of flooding in a small and steep catchment. An important topic for many Norwegian communities. onlinelibrary.wiley.com/doi/…… @NTNUIBM
Simulation of flash flood peaks in a small and steep catchment using rain‐on‐grid technique

Simulation of flash flood peaks in a small and steep catchment using rain‐on‐grid technique

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...

New paper out: Exploring sensitivities to hydropeaking in Atlantic salmon parr using individual-based modelling 🐟onlinelibrary.wiley.com/doi/…
Exploring sensitivities to hydropeaking in Atlantic salmon parr using individual‐based modelling

Exploring sensitivities to hydropeaking in Atlantic salmon parr using individual‐based modelling

Hydropeaking (the release of water pulses at hydropower plants) results in temporary reductions in river channel water-covered area downstream, which may cause fish mortality through stranding. We...

In the long list of beautiful REMs posted on twitter, here is an ugly one. The river Søya in Norway, channelized, the bed level is lowered and floodplains drained. It is sad to see destruction of natural rivers like this. REM based on the method from: @geo_coe.
