Geospatial Information
AgencyTo reduce the level of flood risk, The Directorate General of Water Resources has been
established cooperation between the three government agencies with BIG and BMKG
to make Flood Risk Maps which began on 10th November 2004 and extended 2 times(21st November 2007 and 12th October 2011), this cooperation applies to 12th October
2016.

Basic Idea for Flood Risk Map
Mapping is done using the Geomorphology approach with variables

River

Variables were obtained from a variety of agencies, The Directorate General of Water
Resources can only provide data related to river and coastal management,
For climate conditions and precipitation derived from BMKG, the data for drainage systems fromthe local government and BIG collect them and do the mapping, Therefore it is very important tohave MOU as the basis of cooperation so that risk mapping can be doneRisk Information for Measures of Water-Related Disaster Management

In determining the flood prevention activities both infrastructure and non-infrastructure and every water resource
management activities in Indonesia based on the River Basin Territory Strategic Plan and River Basin Territory
Implementation Plan which is signed and legalized by the Minister of Public Works
Determination of the Plans of River Basin is made based on a lot of variables which are divided into 5 important
aspects, firstly the conservation of water resources, Utilization of water resources, the Management of destructive
force of water, water resources information systems and community empowerment
As for the management of destructive force of water itself requires a variety of information such as the risk oflandslide, tsunami, drought, flood, tidal wave and coastal abrasion up to social and economy disturbance risk map
and the risk of community conflict in Indonesia
With so many disaster-related variable that calculated, it is expected that any development done in themanagement of destructive force of the water can also be integrated so that the risk reduction can be obtained
