Emergency Action Plan for KALLAR March 2021 Emergency Action Plan (Tier- I) Kallar Kerala State Electricity Board Ltd. DOC No. KSEBL_EAP_18_KALLAR _R2 March 2021 i Emergency Action Plan for KALLAR March 2021 KALLAR DIVERSION WEIR DISCLAIMER This is a Tier I EAP document prepared based on Dam Break Analysis carried out using the digital elevation model (DEM) derived from the Japan Aerospace Exploration Agency (JAXA) global digital surface model (DSM) dataset with a horizontal resolution of approximately 30meters (1 arc-sec). Every effort has been taken to estimate the severity of flooding and inundation areas likely to be affected by failure of Kallar Diversion Weir. These estimates are based on available primary and secondary data. Every effort has been made to foresee varied emergency possibilities and develop appropriate notification procedures for timely rescue and relief operations. However, implementation of the Emergency Action Plan (EAP) involves many agencies, who are required to work in a coordinated manner to reduce the consequences of the emergency triggered by the dam site condition. Effectiveness of the rescue and relief operations depend on many factors including the adequacy and accuracy of the estimation of the severity of flooding, coordinated efforts of all the agencies involved in rescue and relief efforts and availability of facilities like power, telephones, road communications, etc. EAP Developer may therefore, not be held responsible for the efficacy of the EAP.
