Abstract: The research investigated the factors for inefficient management of flood plains in Pahala Bomiriya A and Kaduwela A Grama Niladhari (GN) divisions of Kaduwela divisional secretariat of Colombo district in Sri Lanka. It has observed the underlying factors for mismanagement of floodplains while looking at the threats that floodplains face, and the impact of inefficient floodplains management.
