Short summary
The paper models the socio-hydrologic system in a developing city -- Chennai, India -- using "counterfactual trajectories" to understand what might have happened if different decisions had been made 50 years ago. A key contribution is the inclusion of two-way feedbacks between the human, engineered, and hydrological systems. Households are allowed to adapt to decisions made by the water utility. This influences how they use water and consequently how much water is available in the aquifer.
