Simulating Water Flows and Processes
Problem
Water flows can be simulated using computational fluid dynamics, however, solving the underlying PDEs is classically challenging. Other hydrological processes such as precipitation, evaporation, infiltration, and runoff are inherently non-linear, which makes capturing the interactions between these processes in models mathematically challenging. Moreover, many hydrological systems have feedback loops (e.g., soil moisture affecting evapotranspiration rates) that complicate the model equations.
Solution
Quantum algorithms for solving PDEs might ensure stability and convergence while reducing computation time and handling complex boundary and initial condition problems more efficiently, leading to more accurate model predictions. Quantum algorithms, such as the Variational Quantum Eigensolver (VQE) and Quantum Approximate Optimization Algorithm (QAOA), might solve non-linear equations more efficiently.
Impact
This could improve the efficiency, accuracy and speed of simulating complex hydrological processes.
