Sažetak
In this paper are presented Mošćenička Draga investigating sight ongoing hydrological research and sight description. Mošćenička Draga is one investigating sights in the Croatian - Japanese international project - Risk identification and planning of land-use to mitigate the risk of landslides and flash floods in Croatia. Mošćenička Draga is a small village, situated 15 km SW from Rijeka. It is a famous because of its gravel beach. Gravel beach is formed on the torrential flow mouth by a deposition of torrential sediments. Torrential basin area is about 11 km2, average basin slope is very high 47%. Highest catchment point is about 1300 meters. Rainfall intensities are very high. Predicted maximum discharge is 90 m3/s, and that is regulated torrential stream design discharge. Because of catchment and rainfall characteristics runoffs are very intensive and floods were often in the past. Because of that flood defence works have been designed on torrential flow Mošćenička Draga. Today is a great probability of occurrence flooding because of sediment dam fulfilment and potential landslide in the middle of the torrential flow. This Landslide can cause the formation of natural dam, and water can destroyed those dams. Mošćenička Draga torrential flow mouth increases flash flood risks, because of its improper construction. Beside this, the Mediterranean Sea level rise and more frequent and larger magnitude storms in the future are expected to cause frequent occurrence of extremely high sea levels which will result in additional flood risk increase.
