Project Objective : • integrate  land and water management planning using an  integrated  flood 

risk  management  approach to  improve  flood  preparedness  and management within the Nadi Basin.

• Help local communities and other stakeholders to improve their resilience to flooding  through  an  improved  understanding  of  the  river  network  and floodplain interactions

• Designed to  raise awareness to flooding issues

• Project will interlink with other activities working on flood management and risk reduction

• Model for other catchments and sharing of lessons .

Installation of EWS (Mobile texting , alarm/

siren) in Nadi Town

Warning Alarm System(underconstruction )

• Stage one waterlevel warning sent from Flosys Server by text message to key staff to give them a “heads up”

• Stage two warning sent to key staff when things get serious

• Stage three warning text sent to key staff along with an activation message to the siren(s) at a level just below inundation.•Once the sirens have been activated it will sound for a period of time and shut down. Flosys Server will continue to activate the sirens on and off until some one stops them or the river level recedes.

•Public awareness of the warning system and testing can be achieved by setting up an automatic (or manual) activation at a nominated time and frequency.

Formal Agreement Objective

• Establish  Community  Disaster  Management Committees (CDMC)

• train in Disaster Management (DM) • Disaster Risk Reduction  (DRR) primarily  focused on 

Flood management..

To facilitate the completion of:Hazard & Capacity SurveyDRR Action PlanCommunity Disaster Response ArrangementsCommunity Hazard MapConduct a Simulation exercise for community.

Implementation•10 Vulnerable villages identified •Collaboration with Provincial Development –Roko’s Office

• Awareness for the whole village•10 members identified•5 days training •Development of Community Disaster Response Plan •Assimilation exercise – Acid test of CDRP•Handing over of the CDRP to District Officer Nadi / Commissioner West / NDMO /PMU
