Short summary

Superwell is a physics-based hydro-economic model that estimates the production costs and availability of groundwater worldwide. It calculates how much groundwater can be extracted and at what cost, using detailed maps and data of the Earth's properties. Through these estimates, and by using them with other models, Superwell facilitates exploration of coupled human–environmental system challenges, such as future water supply sustainability or multi-sectoral energy–water–land feedbacks.
