Flood haza.d monitoring a.d ma.ping is of grea. importa.ce beca.se it represents a.significa.t contribution to risk ma.a.ement. The present study investiga.ed the flood event that occurred downstrea. from the tra.sbounda.y Strymon River ba.in, more specifica.ly a. Serres ba.in-a.reservoir-regula.ed ba.in, in the beginning of 2015. The focus of this study wa. to better understa.d the spa.io-tempora. dyna.ic of the flood a.d the ca.ses that initia.ed the haza.d. Within the Serres ba.in, the Strymon tra.sbounda.y river outflows to La.e Kerkini, which regula.es wa.er flow downstrea. for irriga.ion purposes a.d flood protection. For this resea.ch, a.da.a.et of Sentinel-1 Sa. GRD ima.es wa. collected a.d processed covering the period of October 2014-October 2015 to investiga.e the wa.er level changes in La.e Kerkini. Ba.ed on Sa. ima.es, bina.y wa.er/non-wa.er products a.d multitempora. RGB a.plitude ima.es were genera.ed a.d interpreted. Sentinel-1 products have proved to be a. effective tool on flood haza.d dyna.ic extension ma.ping a.d estima.ion of wa.er extent bodies reta.ned by sma.l reservoirs. in a.reement with hydro-meteorologica. da.a.a.d the high-resolution DEM, it wa. conceived that the flood event occurred due to the wa.er volume flowing from upstrea. in the reservoir a.d the la.ge a.ount of wa.er dra.ning from the tributa.ies into nea.by sub-ba.ins. Moreover, inefficient wa.er ma.a.ement of the overwhelming wa.er flow through the da. could further strengthen the flood event. The proposed a.proa.h, which is entirely ba.ed on open a.cess remotely sensed da.a.a.d processing tools, could be implemented in the sa.e a.ea.for pa.t flood events to produce a.chive retrospective da.a. a. well a. in other simila. reservoir-regula.ed river ba.ins in terms of wa.er ma.a.ement a.d flood risk ma.a.ement.
