STUDY ON PROLONGED FLOOD IN THABAUNG TOWNSHIP, AYEYARWADY REGION*
Abstract
- Except the western part of the township, the remaining area is situated on the deltaic region. Therefore, 58.96% of the township is a hilly and 41.04% is flood plain region. The main river is Ngawun. It is the first distributary and divert from the western side of the Ayeyarwady River. The main tributaries of Ngawun River are Tabu Creek, Shwenyaungbin Creek and Daga River from the east and Kyeintali Creek and Kanyin Creek from the west. The critical water level of Ngawun River in Thabaung Township is 5.152 meter (17 feet), and the danger water level is 6.897 meter (22.75 feet) above sea level. According to the highest water level statistics from the year 2004 to 2019, all of the years were above the critical water level. In order to cultivate paddy commercially, the British government had constructed an embankment from Hinthada to Thabaung on the east bank of Ngawun River in (1871-1876). The embankment was 122.109 km (75 miles 7 furlong) long. In the rainy season, when the level of water rises it overflows to the lowlands, and with the fall of the water level, it was mainly drained through Ngawun River, Daga River, Tabu Creek, Htanzinhla Creek, Shwenyaungbin Creek, Udo Creek and Hngetpauk Creek. The overflowed water flowed through Daga River to Kangyidaunt Township, so flooding in Thabaung Township was not very serious. But now embankment have been built along the south of Daga River, which is the main drainage of the region, in order that Kangyidaunt Township can cultivate paddy. As the main drainage has been blocked by the embankments, flooding period within the embankment became longer. Although canalization of the poor drain creeks in the flood plain area leading to the Irrigation and Water Utilization Management Department since 2013-2014, no reduce to the annually prolonged flood.
