Erosion Rate of the Aliano Biancana Badlands Based on a 3D Multi-Temporal High-Resolution Survey and Implications for Wind-Driven Rain

Biancana badlands are peculiar landforms in the Basilicata region of Italy resulting from local combination geological, geomorphological, and climatic settings. The evolution mainly depends on slope erosion, which is controlled by angle, exposure, vegetation its interactions with insolation, rain, wind. Multi-temporal, detailed, high-resolution surveys have led researchers to assess changes slopes investigate spatial distributions erosion deposition influence wind-driven rain (WDR). A comparison between two terrestrial laser scanner (TLS) point clouds surveyed during 2006 2016 fieldwork showed that study area suffers intense not spatially uniform all sides biancane. By combining exposure data cloud difference (CoD), derived a 3D model, we steepest southern biancane suffered most erosion. Because splash sheet triggers sediment displacement, analysis was also focused intensity direction WDR. We performed real field experiment analysing rates over 10 years relation daily hourly wind (direction speed), found frequent winds moderate force, combined heavy rainfall, contributed observed increase soil when insolation effect. Our results show how considered factors interact complex pattern control distribution
