Discharge is a platform for non-intrusive, optical flow measurement and large scale acquisition platform for hydrometric and meteorological data. It’s goal is to tackle the globally present problem of water deficiency, by providing the insight into details and allowing to store, organize and utilize the collected data. The original purpose is based on the common requirement for water resources management across large areas of the globe, but it has evolved to be much more than that - providing features like forecasting, alerting, reporting and much more - with costs only at a fraction of the classic approaches.
