On June 26, 2003, a significant landslide occurred at the mileage of 31.5K along the road. The government agency-in-charge, District V, Directorate General of Highways, was therefore installing 6 deep discharge wells at the site (T-1~T-6) in order to lower down the highly raised groundwater level during the heavy rainfall season and to increase the stability of the slope. The study herein was conducted on the discharge well T-2. With the installation of flow meter and piezometer in the well, this paper discusses results of the monitoring and the effect of the pumping / precipitation on the groundwater level and slope deformation at the site.
