Q100: KAS Prelims 2020 GS-I: Previous Year Question with Answer

Consider the following statements: 1. One of the largest flooded areas was those adjacent to the backwaters along the coast. Areas adjoining these wetlands that are normally flood-free were flooded to a large extent. 2. The outlets to the sea, (pozhis/sand banks and spillways), did not have the capacity to evacuate high flood flows from the rivers, as they occurred, into the sea and thereby aggravating the floods. 3. The flood situation in the coastal areas was intensified by the perigean spring tide, during 11–15 August 2018. 4. Sustained strong onshore winds, resulting in abnormally high sea levels, hampered river outflow into the sea and intensified the flood. Which among the following statements, listed above, are true with regard to the Kerala floods of August 2018?
