Infiltration is the process of water entering soil, crucial for hydrology in understanding rainfall-runoff processes, flood estimation, and groundwater recharge. Infiltration indices are empirical tools used to analyze storm runoff and estimate effective rainfall, providing simplified representations of complex infiltration behaviors. Various indices, including φ-index and W-index, help hydrologists estimate runoff while considering initial losses and storm characteristics.
