Implication

This analysis reveals soil retention and erosion dynamics in the Ilam watershed, suggesting enhanced land management strategies for ecosystem services.

Key Points

To assess soil retention, erosion potential, and sediment transport using the InVEST and SDR models in the Ilam watershed.
Utilized InVEST and SDR models for analysis.
Incorporated factors like rainfall erosivity, soil erodibility, DEM, land use, vegetation, and conservation practices.
Conducted a detailed examination of the Ilam watershed.
Average soil retention was found to be 94.5 tons/ha/year.
Average erosion potential was assessed at 62.8 tons/ha/year.
Sediment transport averaged 10.5 tons/ha/year.
Forest areas retained about 60% of sediment with low discharge at 13%.
Agricultural and urban regions were identified as major contributors to erosion.
