Presented at The Collaborative Workshop of Sedimentation and Dam Technology Malang, 18th December 2013 Page 1 Brantas River Basin
An archipelago of 13,000 islands – 240 million inhabitants – 5,600 rivers all over the country – divided into 131 river basins – Brantas is one of the strategic river basin of out 33 selected basins (President Decree No. 12/2012).
Brantas River Basin (12.000 km2) Length = 320 km Population in CA = 16 million people
Brantas River Basin = 25% area of East Java Province GRDP Brantas River Basin = 64 % GRDP in the East Java Province (as of 2009)

Page 7 FLOOD FORECASTING AND WARNING SYSTEM (FFWS) 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.

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.

Page 20 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 21 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.
