The study was conducted to assess the erosion-sedimentation system and its water quality implications in a subwatershed of Taal Lake, Philippines. Sheet and rill erosion from the 200-ha Angasin watershed was estimated using a modified Universal Soil Loss Equation. The average and total soil losses were 45.72 tons/ha/yr and 9,144.61 ton/yr. respectively. Among the three types of land cover and for all slope ranges, soil loss per unit area was found highest from areas under diversified cropping followed by shrublands and the least was from coconut areas. Sedimentation is known to affect the quality of receiving waters. Cs was found to significantly affect turbidity and iron concentration (both quadratic), phosphate concentration (geometric), and nitrate concentration (linear).
