The Cagayan river basin is the largest in the
Philippines, encompassing the provinces of
Nueva Viscaya, Isabela and Cagayan. The
basin is affected by recurring floods due to
tropical cyclones and the northeast monsoon.
To mitigate the impacts of flooding in the
valley the Philippine Government established
the Cagayan Flood Forecasting and Warning
System (FFWS) in 1982. The Cagayan FFWS
is equipped with six combined rainfall
and water level stations, one field station
in Tuguegarao, Cagayan, and one repeater
station in Ilagan, Isabela.
The Flood Forecasting and Warning System
which was in place in 1982 and upgraded in
1992 with the inclusion of a warning system
for operation at Magat Dam (multipurpose
dam for irrigation of 102,000 hectares of
farmland and power production), has since
encountered problems including breakdown
of the communication system and some of
the monitoring stations. The communication
link between PAGASA and the National
Irrigation Administration-Magat is no longer
operational and data from the automatic
stations are no longer available in real
time. The ability to warn affected people
downstream and to operate the spillways
of the Magat Dam satisfactorily in order to
decrease the flooding risk is therefore very
limited.
In June 2008 Norad asked NVE to assist
PAGASA in the preparation of a proposal
for rehabilitation and upgrading of
the system. A field visit including an
assessment of the station network was
conducted by NVE officials in November,
after which the proposal was prepared in
close cooperation with PAGASA on how to
structure the potential Norwegian support
for rehabilitation and upgrading of the Flood
Forecasting and Warning System.
