—A model was constructed in compliance with the
real conditions to study the behavior of total suspended solids
(TSS) on the partially covered road side slopes. The study was
performed in Perak, Malaysia where the average high rainfall
intensity was found to be 52 mm/hr from the year 2005 to 2011.
The results attained showed fluctuations in the TSS
concentration observed from the partially covered soil surfaces
that could have happened due to several reasons which are
discussed in the paper. A sandy loam on a slope gradient of 30°
was observed. Four plots were prepared namely, fully grass
covered surface (plot A), bare soil surface (plot B), 50% of the
grass covered surface (plot C), and 30% of the grass covered
surface (plot D). The concentration of TSS was found to be very
severe, attained from the bare soil surface (plot B). However,
the maximum TSS values obtained from plot A, C, and D were
found to be 22.29%, 45.62%, and 78.90% respectively of the
maximum TSS value observed from the bare soil surface.
