We give an approach for using flow information from a system of wells to characterize hydrologic properties of an aquifer. In particular, we consider experiments where an impulse of tracer fluid is ...

Figure 1: First-order Markov dynamics distort real constraints on flow. Although we considered passengers moving between cities in this illustration, we have analysed six diverse systems in detail, ...

AI can help predict flood risk in hills, where traditional defenses are costly. Research shows flexible plants reduce peak ...
