Simulation of Active Layer Dynamics, Upper Kolyma, Russia, using the Hydrograph Hydrological Model
ABSTRACT Freeze/thaw simulations were performed for seven permafrost sites at the Kolyma Water Balance Station (KWBS), northeast Russia, using the hydrological model Hydrograph equipped with a heat transfer analytical solution that accounts for soil profile phase changes. The study sites include slo...
