Recent flood in Gampaha district and its’ consequences

Abstract

As a research of short periodical time basically using secondary data we focused on the severe critical reasons for the recent flood based on Gampaha district. The main water resource of this area “Kelani River Basin” is deeply analysed on a perspective view. Illegal constructions on wetlands in this thickly populated area are a main strategic reason that we had analysed. The sudden climate changes also use to occur in Bay of Bengal affected with heavy rain the flood with highest rain fall. But there natural ways had been blocked to flow into sea. These points are reliably explained with the map of Survey Department and Irrigation Department. Water reservoir damps play a certain role in this case. Our major objective is to prevent and secure the Gampaha and Colombo sub urbans from flood. Stopping illegal constructions and reducing the population by facilitating all facilities to villages, and transferring or replacing the present crowd to another place are some alternative long term plans regressed. In future we expect to do a very large scale of research with ample primary data collections.
