Interactive flood-risk simulation for urban Chennai — terrain-based drainage analysis with a real-time "what-if" rainfall scenario engine. DEM pipeline → simplified hydraulic proxy (HEC-RAS upgrade planned) → live web dashboard.

There are already applications for managing and distributing waste in Indonesia. With those apps as a reference, we tried to design a similar application by emphasizing the unique aspects of sorting and channeling types of residential waste. We want to make an application that can detect six types of residential waste by scanning the camera on a…
