A geotechnical engineer from Kasetsart University analyzes Nan Province's recurring floods, arguing they stem from geographic inevitability (valley terrain, monsoon exposure, steep slopes) rather than engineering failure alone. He identifies three critical management tools: building regulations, engineering infrastructure (dams/retention), and early warning systems. Key insight: barriers create false security; without medium-sized reservoirs or stricter zoning laws enforced locally, regulations and adaptive urban planning are the most viable defenses for SMEs and communities in disaster-prone areas.
