THE IMPACT OF FLOODS ON HUMAN AND ENVIRONEMNTAL SYSTEMS IN WET ZONE SRI LANKA

Abstract

This study explores the complex effects of floods on people and environmental systems in the wet zone of
Sri Lanka. The study examines mitigation techniques, examines the contributing elements to flood risk, and
emphasizes the vulnerability of ecosystems and human settlements using both qualitative and quantitative
data. Flooding has a major effect on both human and natural systems in Sri Lanka's wet zone, especially in
places like Colombo, Gampaha, Kalutara, and Kegalle. The frequency of natural disasters has increased
tremendously in recent years, among other challenges that have surfaced in both developed and developing
nations. In January and February, the northeast monsoon sends a good deal of rain to the eastern side of the
central hills, the lowlands that surround them, and to a lesser extent, the northern regions of the island. In
the months of June through September, the South West Monsoon brings precipitation to the western and
south-western slopes of the central highlands and, to a lesser extent, to neighbouring lowlands in the South,
West, and Southwest. Inter-Monsoons – October through November and March through April are the
rainiest months on the island. because of frequent weather system formation and convectional activity,
particularly in October and November. The first inter-monsoon, which spans March through April, is
distinguished from the second inter-monsoon, which spans the final two months. In this research paper,
authors have studied impact of floods on the human lives and environment system especially in wet zone of
Sri Lanka as there are dominating factors that caused degradation in country overall. Lots of economy and
health issues occurred during the floods. Nevertheless, authors have also identified the flood mitigation
programs, initiative schemes, challenges towards flood management and environmental issues.
