Summary
This narrative review examines the evolution of process-based hydrologic models, tracing how scientific debates over parameterisation adequacy, data limitations, and computational constraints have shaped model development. The authors illustrate how advances have emerged from diverse modelling approaches and argue that leveraging this diversity of methodologies is essential for achieving more physically realistic representations of hydrologic processes.
UK applicability
The methodological framework and challenges discussed are directly relevant to UK hydrologic research and water resource management applications. UK-based hydrologic modelling communities would benefit from the synthesis of advances and recommendations for integrating complementary modelling approaches to improve predictions of catchment behaviour.
Key measures
Model equation formulations, parameter adequacy, computational constraints, process parameterisations, model complexity trade-offs
Outcomes reported
The paper reviews historical challenges in process-based hydrologic modelling and documents modelling advances across different model types and complexities. It identifies outstanding research needs for improving physically realistic hydrologic representations.
