Electricity Generating Authority of Thailand (EGAT) has currently owned fourteen large dams constructed for irrigation, flood prevention, power generation and so forth. In order to ensure dam safety, EGAT has monitored dam behavior through its dam safety program since 1982 and has been improving the processes according to the international standards, one of which was to initiate an automated Dam Safety Remote Monitoring System (DS-RMS) in 2013. DS-RMS is a collaborative project among EGAT, Geotechnical Engineering Research and Development Center – Kasetsart University (GERD-KU), and National Electronics and Computer Technology Center (NECTEC). The main objective is to automate conventional acquisition of safety-related measurements so that comprehensive information are remotely obtained in realtime. Fourteen dams across the country and the central office are equipped with reliable remote terminal units (RTUs), communication links, computer servers and advanced monitoring software as shown in Fig. 1 and 2.
