By exploiting technological options reminiscent of these described under, the nation can cut back the influence of flooding on the nation’s economic system.
Wi-fi Emergency Alerts (WEA)
Collaborating with cell phone community suppliers to make provisions for Wi-fi Emergency Alert by the authorities is a possible technique to forestall the disaster coming from the floods. WEA will concern warnings if there’s a hazard to close by life reminiscent of extreme flooding.
