bottom layers - move water above upper limit to next layer up top layer if no depressional storage (wetland), add to surface runoff check if entire profile is saturated - could get excess in first layer if irrigating on frozen soil if still saturated if depressional storage, add to ponded water if no depressional storage, add to surface runoff rtb gwflow: add ul_excess to runoff storage !!!! Ryan please check; move water and nutrient upward and add to wetland storage Jaehak 2022 this is not actual upward movement of water and nutrient, but a process computationally rebalancing water and mass balance in the soil profile add ratio of nutrients to be reallocated to ponding water substract the fraction of nutrient in the top soil layer add to the wetland water nutrient storage
