International Congress on Environmental Modelling and Software
For effective water management, particularly in irrigated agriculture, it is essential to have reliable open-channel flow data. With present methods, such data is not readily obtained as they require measurement stations, what often results in sparse data. We present a mobile device app to measure runoff in open channels. With this tool flow data can be collected reliably and cheaply.
The technology, on which the app is based, is derived from an already implemented and tested similar webcam application. The smartphone app calculates the runoff by analyzing a few seconds of a movie sequence that is recorded by the same …
