3) Designed and improve the drainage system to alleviate the severity of floods an upper zone of Mae-On watershed areas makes line of fire, including regeneration and repair the forest To absorb water and slow runoff, improvement of flood retention basin restoration and bending pond sludge to support the increased flood and sediment trapping by capacity design. The Central zone of Mae-On watershed areas designed the dike with a height from the waterline to the lowest 1.50 meters and has a length to 6.10 kilometers and design channel water diversion has a length to 2.25 kilometers can divert water to 1.20 cubic meters per second and the ability to retain water for use during the dry season to about 2.2 billion cubic meters and downstream zone of Mae-On watershed areas designed the water diversion system channel along with Kaem-Ling system to drain water out of the area has a length of 14.36 kilometers and can divert the water 10.13 cubic meters per second. Kaem-Ling System can retain water for use in the dry season, about 4.1 thousand cubic meters, adding water distribution has a length of 13.17 kilometers can distribute the water 3.08 cubes per second and can storage water for use in dry season around 5.8 thousand cubic meters. The river has improvement and get a length to 14.40 kilometers to make water flows through the convenient during the rainy season and land or zone management to use the land and prevent the invasion river.
