- [How a flood early warning system works: observation, forecasting, decision and response](https://climmatech.com/resources/blog/how-a-flood-early-warning-system-works): A flood warning is a chain of five links. Each has its own engineering, its own failure modes and its own share of the time you have. Here is how the chain fits together, with a worked routing example and the numbers that measure whether it works.
- [Why surface velocity matters as much as water level](https://climmatech.com/resources/blog/water-level-and-velocity-together): A river's height tells you how much water there is. Its speed tells you how soon it will arrive.

## Scope notes

- TARANG and PRAVAAH measure water level, and PRAVAAH also measures surface velocity. Calculating river discharge additionally needs a surveyed cross-section and a calibrated relationship between surface and average velocity.
- RAKSHAK sounds warnings that a connected monitoring system, agency or operator decides to send. It does not detect or predict hazards by itself.
- Enclosures are described as weatherproof. No IP rating or third-party approval is claimed for the devices.
- The Data Logger and the Rakshak Control Centre are upcoming.
- Prices are not published. Systems are designed to be low cost and are quoted for each project.
