1 Introduction and Overview: Regional Workshop & Study Tour on Groundwater Information in the LMB Hydrology Team Information and Knowledge Management Programme Mekong River Commission Secretariat Regional Workshop and Study Tour on Groundwater Information in the Lower Mekong Basin 17 February 2014 Bangkok, Thailand

2 Scope and Objectives of the Workshop and Field Visit General Objectives Current situation on groundwater monitoring systems in the LMB; Learn from experiences in Thailand with respect to groundwater resources management Development of a Groundwater Database for the Lower Mekong Basin Continuation of the cooperation with USGS Preliminary action plan and strategy for future MRC groundwater monitoring activities in cooperation with Line Agencies of the Member Countries. Groundwater Resources in a Global perspective Freshwater Resources globally and regionally Example of Groundwater Resources in a Region Detailed investigation on 2 Cambodian Provinces On site investigation exchange between Groundwater and Surface water
