DEVELOPMENT
System Features
– Installed and established at the end of 1990 and started its operation from the
beginning of 1991. The hardware and software systems of FFWS 1st
generation were installed in the Brantas River basin through the Japanese
Overseas Economics Cooperation Fund (OECF) project.
– Additional two rainfall stations were installed at Tugu and Kampak in 1993.
– An extension of FFWS installed in 2000 supported by the Government of
Austrian through Indonesian Institute of Science (LIPI).
– The existing FFWS consists of observation system, telemetering system, flood
analysis system, and communication system.

Problems on Existing FFWS
1. Lack of Spare Parts
The equipment has not been produced since 1996. The spare parts are now out of stock (discontinued).
2. Processing of Telemetering Data
Difficult to change the H-V curves as they are memorized in the ROM of the Data Processing Equipment.
3. Telemetering Data Management
Disconnection between the new database and the Data Storage Equipment.
4. Flood Analysis System
The flood analysis system has not been applied yet to actual flood events since its establishment.
5. Communication System
Interfered with other wireless stations using similar frequency band.
6. Observation at Gauging Station
Some water level gauges are not functioning due to sediment deposit especially in the dry season.

Flood Management in the Brantas RB
• Floods can not be prevented totally in the Brantas RB.
• Flood control has been shifted towards flood management.
• The resilience of community to live in harmony with floods
such as community service and empowerment of society is
the most important component.
• Provision of EWS and flood hazard mapping and risks
guides, raising awareness, capacity building, education and
training, as well as institutional setting.
Page 22
CBFEWS in the Brantas RB
• EWS is a key element in reducing flood disaster
risks in the basin.
• It provides people with sufficient time to evacuate
and protect their property from an impending
hazard.
• The CBFEWS in the basin provides community
and disaster risk management agencies with
advance information on the risks that can be
readily translated to disaster prevention,
preparedness response actions against loss of
lives and injuries.
• The system promotes a sense of ownership,
hence it is easier to sustain.
