Reader Briefing

Senator Cheevapap Cheevatham attributes flooding in Nan province to the degradation of headwater forests and urban planning that ignores natural water flow paths.

•Senator Cheevapap Cheevatham identifies degraded headwater forests and infrastructure blocking water paths as primary causes of Nan floods.
•Senator Cheevapap Cheevatham proposes using the 'Aspect' (slope direction) principle for urban planning and flood warning systems.
•The Senate Committee on Natural Resources and Environment plans an urgent meeting this week to address the issue.

Overview

•Senator Cheevapap Cheevatham stated that floods in Nan reflect a failure to consider watershed management and land use principles.
•Nan province is a watershed area and the origin of the Nan River, containing sub-watersheds such as Khun, Khwang, and Pua.
•In areas like Ban Fai in Pua District, headwater forests at Doi Phu Kha and the Khun and Khwang streams have become bald mountains, losing their ability to slow water flow.
•The degradation of forest structures causes rainwater to flow immediately through streams and fields into communities during heavy rain.
•Roads and bridges constructed by the Department of Highways, Department of Rural Roads, and local administrative organizations often ignore the 'Aspect' principle, causing flash floods to overflow main roads.
•Senator Cheevapap Cheevatham noted that existing warning systems lack practical effectiveness and need rainfall and water level sensors on mountain peaks.
•The Senate Committee on Natural Resources and Environment will hold an urgent meeting this week to consider systematic water management and headwater forest solutions.
