DIRECT:
3.- Reduction of runoff and erosion
14.- Slowing down of water flow
15.- Retention of run-off water in field with slight slopes
INDIRECT:
4.- Improvement of water infiltration (micro- and macroporosity) and avoidance of floods and landslides
10.- Avoidance of contamination (local and diffuse)
16.- Redirecting of water flowing downhill
17.- Providing soil with more time for water infiltration
18.- Cut off pathways of concentrated run-off water allowing water permeability
19.- Protection of downstream areas by retaining and cleaning run-off water of sediments, nutrients, and PPP
