The smi ulation included pretrea tm ent o topographic data, running o m od i ied MTCL IM, and smi ulation o orest dynam ics. The develop- m ent and validation processes o th ism odelw ere described, and the deta ils o the m odel, including the app lication o G IS and the param eterization o clmi ate and physiolog ical actors, w ere presen ted. 2 T he smi u lation results o a rea l catchm en t ( 139 hm ) in W o long Reserve show ed that this mode l cou ld describe the physio log ica l processes and spatial dis
