Rainfall-Runoff Modelling: A Review of Empirical, Physically-Based and Machine Learning Approaches and Climate Change Applications

Dasari Omkar, S. Selvakumar, S. Pazhanivelan, M. Raju, K. P. Ragunath & V. Ravikumar · International Journal of Environment and Climate Change · 2026

Rainfall-runoff (R-R) models are the foundational computational tools of applied hydrology, underpinning flood design, drought monitoring, reservoir operation, irrigation management, and climate change impact assessment. This paper provides a comprehensive global review of R-R mo...
