Further develop existing EWS and replicate the systems in other regions.
Even though they didn’t function entirely as planned, the EWS in Kailali and Bardiya Districts dramatically reduced loss of life and property. The EWS should be further strengthened by addressing single points of failure (e.g., battery backups, gauge-reader backup), improving communications protocols, and increasing local awareness of risk. The Karnali Basin EWS should be replicated throughout Nepal wherever there is flood risk, where upstream gauge data are available, and where it is feasible to set up a communications structure to transmit warnings. To provide additional lead time, the EWS should also be linked to precipitation forecasts, real-time precipitation measurements and river flood forecasts. Current real-time precipitation, which is measured at more locations than river flow, could be used to ‘pre-alert’ first responders to potential danger so that they are ready if danger escalates. Early warning can be further strengthened by linking upstream and downstream communities. Given lack of flood forecasting, the lack of EWS in much of Nepal and the potential for EWS delay or failure where they do exist, this will allow for transfer of warning information and will build redundancy into the warning system. It offers an alternative way to transmit information where there are no warning systems. Links can also be used to encourage social learning and help with preparation, response and recovery.
