SWAR-MRMT-R

This model simulates concurrent nonlinear multicomponent biogeochemical reactions in both the channel water and its surrounding hyporheic zones (HZs), connecting the channel water and HZs through hyporheic exchanges using multirate mass transfer (MRMT) representation. A two-step reactions for denitrification and an aerobic respiration reaction are assumed to represent the biogeochemical transformations taking place within the HZs.
