At present Thailand is one of the Asian countries acknowledged as a Newly Industrialising Country (NIC). The economic and social structures have been improving through the National Economic and Social Development Plan. In the past, unsystematic utilization of natural resources, especially water and soil, has resulted in serious natural resources and environmental quality deterioration. Many intense conflicts have arisen between the use of natural resources and the need to protect the environment. Thus, to promote efficient use of the deteriorating and diminishing natural resources consistent with the protection of the environment, while at the same time finding additional resources to be used in future development, natural resources and environmental development strategies should be formulated. Watershed classification is one of the governmental attempts to manage the headwater area of the inland aquatic ecosystems for desirable quality and regulation of water flow along with soil erosion control, flood reduction and other resources utilization. These strategies are very important for the country's development. When many of the national resources are facing various constraints as in the present period, it is especially necessary to put more emphasis on efficient management
