unsteady modelling in steep reach
dear all,
what would you recommend to obtain stability for an unsteady calculation in a very steep torrent (slopes up to 25 percent). The model is running well for slopes up to 15 percent, afterwards stability problems are showing up. The hydrograph is also quite steep, raising form a base flow of 1 cms up to 120 cms in 15 minutes.
Thanks in advance for a reply.
