Abstract


Studies of the role of combined vegetation cover and catchment characteristics on base flow
condition are required to address the controversy of correlation between vegetation and
hydrological properties. Objectives of the research were: 1) to assess the hydrological role of
vegetation on baseflow condition; and 2) to study the influence of vegetation cover in relation
to catchment characteristics on the baseflow. Field survey, digital filter method, remote
sensing technique, and statistical analysis were used to derive and assess the correlation
among variables. Results of the research were: 1) a negative significant correlation between
vegetation cover and baseflow recession coefficient, despite the fact that it is not a single
factor and related to various catchment characteristics; 2) vegetation cover is not a single
factor in determining the baseflow characteristics, since it also involves drainage density and
infiltration rate.
