Land use in the upstream area will have an effect on downstream either profit or harm related to risk reduction or risk amplification. Development of reservoir in upstream area will lessen flood risk on downstream; on the contrary addition building area in upstream area will improve flood risk on downstream. At first case, downstream area give incentive for upstream area, quite the opposite at second case downstream area accept the compensation from upstream. This research tries to explore potency of applying risk trading in trans boundary flood management. Reciprocal model of risk trading above will try applied in Bengawan Solo catchment area by taking case of Surakarta city as downstream area, whereas Wonogiri and Karanganyar Regency as upstream areas. Rational method and direct damage calculation applied here. Result of Research show the existence of increasing flood risk in Surakarta city cause by urbanization in Karanganyar regency that is addition inundation area equal to 66,58 ha (21,71%), quite the reverse happened flood risk reduction effect of flood control by Gajah Mungkur reservoir in Wonogiri regency that is decrease inundation area equal to 562,28 ha (64,71%). Compensation of Karanganyar regency for flood loss in Surakarta city equal to Rp.4.218.631.500,-, while incentive of Surakarta city for flood control by Gajah Mungkur reservoir in Wonogiri regency equal to Rp. 29.239.934.900,-.
