survival of the people living in the village. The " Uwe" river should be preserved but the current situation is the opposite. The


preservation of the “ Uwe” river has received little attention from the government, whether in terms of transportation facilities,


residential facilities or infrastructure in accelerating regional development. Wesakin Village has been one of the areas

development where the banks of the " Uwe" river, settlements are now starting to become disorganized due to natural disasters


such as landslides and flash floods. which once affected Wesakin Village. There are two morphological changes, namely


morphological changes in community residential areas and natural morphological changes that occur in changes in the
