Alternative methods to control water infiltration for landfills: a case study in the tropics
Result description
In this research, a vegetative cover using a naturally occurring soil of Hawaii was tested. As the annual rainfall at the site is more than the evapotranspiration demand, a portion of the run-off was routed offsite using run-off-enhancing structures suchas rain gutters. The site contained six test plots on 4% slopes to simulate different components of water balance: two control plots, two plots with 20% surface area covered by the gutters and two more plots with 40% area covered by the gutters. The gutters were spaced uniformly and enhanced run-off in early stages of vegetation growth. With growth, the vegetation covered the gutters and the gutters did not receive as much rainwater. The difference in run-off between the 20% and 40% was not significant. If the gutters had been placed at a single location in the plots, they would not have been covered with vegetation, thus making them effective to produce runoff in most stages of vegetation growth.
