Hello! Yellow Sub Hydro is a proudly triple-bottom-line B Corp certified business seeking to profitably address BIG climate change-related problems with passion and purpose. We have developed a water resource management engineering Software as a Service (SaaS) product. More than a model, this cloud based application offers near real-time simulations of coupled surface and groundwater at catchment scale. We call this virtual environment for interactive and collaborative experiments on the hydrological system, Periscope. Periscope is an entirely new system of managing and communicationg strategic water resources – reimagined from first principles – where ALL stakeholders in water can evaluate a broad range of ‘what if’ scenarios’. By democratising access to data and decisions around water in this way, we (as a population) dramatically increase our chance of making better decisions around our most precious of shared resources. Part of a B Corp Group.
