Circulation weather types as a key factor on runoff initiation and sediment detachment in Mediterranean shrublands

In this research, the circulation weather types (CWTs) associated with individual surface pressure data at different atmospheric heights were used to correlate and quantify soil erosion events collecting loss (g m-2), runoff (l m-2) sediment concentration L-1) using field plots collectors. Representative Mediterranean shrubland, located Sierra de Enguera (Eastern Spain), was as a case study where 213 rainfall episodes related recorded for 2010-2014 period. Average annual precipitation of 544 mm registered, summarizing total 2,720.1 five years research A 34.4% registered ranged from 10 29.9 mm, 23.5% 30 49.9 15.9% 50 99.9 mm. The dynamic low-pressure fronts (DLp+f) CWT found generate highest amount reaching 60.6% (105 events). Over third (35%) occurred during Eastern CWT, which accounted 48% average values 17.6 per event. From runoff, 65.6% combined cold drops (CD) CWT. DLp+f produce 48.9% mobilization, 73.5% generated by event southern under thermal (TLp) 51.65 g L-1, followed (anticyclones) (42.23 L-1). As whole, is generating (28.66 L-1), Easter Our findings suggest that CWTs contribute foreseeing periods losses may help prevent them. We discuss need analyse changes in rates due better characterize process assess rates, improve current models investigate how climate change changing role plays initiation delivery.
