This project focused on mitigating flooding in the Khlong Toei slum in Bangkok, Thailand. Flooding in Khlong Toei is caused by the torrential downpours from monsoons in the rainy season and leads to many health and sanitation concerns. The key contributors to flooding that we identified were failing drainage systems, inadequate waste management practices, and poor relations between residents and stakeholders. We created a collection of geographical maps based on our interviews and first-hand observations and measurements in order to convey the susceptibility of certain areas within the slum to external stakeholders. Additionally, we formulated a series of recommendations to improve the waste management practices and the drainage infrastructure within the slum.
