Dendrohydrological Reconstructions Based on Tree-Ring Width (TRW) Chronologies of Narrow-Leaved Ash in the Sava River Basin (Croatia)

Current flood risk management is based on statistical models and assessments of the occurrence over a given time period, although with very short measurement periods, usually following catastrophic events. Ongoing monitoring basic hydrological (river-water level streamflow) climate data are basis for sustainable water long-term control planning. The lack has proven to be particularly negative during this period global change, when non-seasonal flooding (during summer) becoming increasingly frequent, resulting damage greater. aim study was analyse possible use tree ring width chronologies trees growing in floodplain areas reconstruct hydrodynamic variables streamflow). analysed influence climatic growth narrow-leaved ash (Fraxinus angustifolia Vahl) Sava River basin. results indicate significant potential tree-ring summer streamflows (R2 = 0.45). These can serve develop series river, thereby enabling better insight into its spatial temporal dynamics goal more successful, areas.
