“…Event‐based hydrologic modeling defines the response of a basin to individual rainfall events, while continuous hydrologic modeling accounts for basin outlet response to multiple rainfall events by considering dry and wet periods. A more realistic way to define a hydrological model is to conduct a complete study and analysis of the hydrological cycle and its components at the basin scale (Aishi et al, 2023; Sempewo et al, 2022). Climatic and watershed physical properties and parameters need to be defined to understand the watershed response.…”

The rapid and frequent mapping of flood areas is crucial for monitoring and mitigating flood disasters. This study aimed to devise a flood inundation map for Nandigama City, located in the state of Andhra Pradesh, India. To analyze flood inundation, the HEC‐HMS hydrologic model was used to assess the effects of land‐use changes on runoff. The analysis of land use and land cover (LULC) revealed a significant increase in urban expansion around the study area over the last 30 years. The rise in urbanization and impervious surfaces has led to an 11.85% increase in the average peak discharge, from 4.39 m3/s in 2000 to 4.91 m3/s in 2020. These findings can provide significant insights for urban policymakers in the planning and management of flood control infrastructure in Nandigama.
