Implementing geographic information system in 2011 thailand flood studies and north east asia environmental activities

2011 Thailand flood brought serious impact to downstream of Chao Phraya River Basin. First part of this paper explained the used of Geographic Information System (GIS) in assessing the flood condition at midstream of Chao Phraya River Basin, which is Nakhon Sawan area includes confluence of Nan River and Yom River, also confluence of Ping River and Nan River. The flood peak period started from August to the end of October, 2011. The main purpose is to understand the flood generation, estimate the flood volume and loss of paddy field, also recommends applicable flood counter measurement to ease the flood condition at downstream of Chao Phraya River Basin. Subsequently, three scenarios of flood control are simulated and GIS is used to assess the reduction of loss estimation in paddy field. In addition, loss estimation for paddy field at midstream is evaluated using GIS with the calculated inundation depth. Results show the proposed flood control at midstream able to minimize 5% of the loss in 26 provinces. Second part of this paper describes implementing GIS into East Asia environmental activities. Three months internship has been experienced at United Nations Economic and Social Commission Asia Pacific – Subregional Office for East and North-East Asia (UNESCAP-SROENEA) and variety of maps has created for its project, particularly Marine Protected Area, Transboundary Air Pollution and Migratory Birds. Furthermore, Geodatabase is proposed for updating, maintaining, storing and displaying spatial data effectively.
