WARNING! This application has been deprecaded. It was originally developed as a proof-of-concept to show the value of integrating timelapse imagery with hydrologic data. This work later led to the development of the EcoSHEDS Flow Photo Explorer, which is a crowd-sourced database and machine learning platform for predicting streamflow from timelapse photos of streams and rivers.
