Description :
This paper presents a reconstruction of the development of the Dragonja floodplain due to these land use changes during the last 60 years. The reconstruction is based on dating of floodplain sediments using Cs 137 profiles, measurement of actual sedimentation rates using artificial grass sedimentation mats, and linking this information to the present-day hydrological behaviour of the river. The sedimentation mats show that floodplain sedimentation was restricted to peak flows of considerable magnitude. Due to the reforestation, the return period of such high flows increased from the period 1960-1985 to the period 1986-2003.
