Hydrological connectivity disruption in riparian corridors represents one of the most pervasive yet under-quantified drivers of freshwater biodiversity loss. This study presents a spatiotemporal analytical framework integrating high-resolution LiDAR-derived terrain modeling, multispectral remote sensing, and benthic macroinvertebrate bioassessment to diagnose and prioritize restoration targets across 47 fragmented riparian reaches in the Danubian lowland system. Structural equation modeling revealed that lateral connectivity indices (LCI) accounted for 68.4% of variance in EPT (Ephemeroptera, Plecoptera, Trichoptera) richness, outperforming longitudinal gradient metrics. Hyporheic exchange flux reduction, driven predominantly by agricultural impoundment, demonstrated significant threshold effects at LCI values below 0.31. The proposed Riparian Restoration Prioritization Index (RRPI) successfully identified high-leverage intervention nodes, offering a transferable, operationally scalable protocol for watershed management agencies confronting compound biodiversity and hydrological degradation.
