Abstract
Predicting and estimating surface runoff in Mainland Southeast Asia (MSEA) is essential for the assessment of water receiving potential of a watershed and for an appropriate planning of soil and water conservation measures. Due to MSEA rapid development, industrial, urban and population growth cause land degradation across the whole region.</br> Even if several research have highlighted the need for long-term catchment studies to guide future proper runoff measures and management policies, runoff knowledge in the tropical region of Southeast Asia is still insufficient. In particular comprehensive studies having a regional focus at the multi-basins scale have not been addressed before in MSEA.</br> This work aims at setting up an empirical model for the surface runoff estimation at the multi basins scale in the Mainland Southeast Asia. We present preliminary results of annual and monthly estimations of surface runoff distribution using the SCS-CN model approach from 2000 to 2020
