Abstract: The Study area is Yezin Dam which is located near Yezin village, on the east of Yangon-Mandalay Highway, Zayarthiri Township, Nay Pyi Taw City. The main aim of the construction of the dam is irrigation for the agricultural areas. The satellite images between 2006 and 2016 are used. Three Landsat Enhanced Thematic Mapper Plus change of water surface area in Yezin Dam are examined over 10 years period. (Landsat 7 ETM+) images were acquired on 05 April, 2006, 03 April, 2011 and on 16 April, 2016. The objectives of the study are to examine the changes of water surface area in Yezin Dam and to compare the different areas between satellite image and field study. The data such as temperature, rainfall, inflow water, outflow water and water level are used. The changes are tracked from the images using Band 2 (Green) and Band 4 (NIR) with the help of Normalized Difference Water Index (NDWI). The accuracy is assessed by using the Normalized Difference Area Index (NDAI) method. Results show that the accuracy assessment is 97% in 2006, 79.15% in 2011 and 92.2% in 2016. Satellite data can point out the water surface changes. The water surface areas decrease more than 75.12% during 10 year period.
