Description :
This study examines flow pathways within lowland rain forest slopes comprising Udults of the Ultisoil order. Experimentation was conducted on 4 SE Asian hillslope units in the Bukit Timah catchment (Singapore Island), and in the W8S5 catchment (Sabah, Borneo Island). The flow pathways were identified by artificial tracer experiments. The AA. evaluated how well hydrometric calculations based on tensiometry and permeametry measurements predicted the tracer patterns. The results indicate that marked variations in flow vector exist within the Udult great group of SE Asian soils and hydrometric calculations may be poor predicators of these dominant pathways.
