“…Muthusamy et al, [54] estimated urban flooding using HEC-RAS, and they compared the outcome of modeling with the extent of water depth, the effect of the fluvial flooding, and the combined effect of both fluvial and pluvial flooding. Gholami [57] investigated the flood in the Hyrcanian forests of northern Iran based on HEC-RAS, and he calibrated the hydraulic model based on making flood depth in the field.…”

Hydrological models significantly estimate water movements and their distribution at local and catchment sizes. They have been used to simulate the relative between rainfall and runoff. They enhance city planners and hydrology communities to investigate the complex relationship between precipitation and runoff in catchment and city sizes. Water movement is a vital matter, especially on the ground. This study reviews several hydrological modeling studies in different environments, including spatial analysis in the Watershed Modelling System (WMS). It seeks to consider only the most critical Hydrology and Hydraulic Modelling to investigate water in a watershed. Furthermore, this review gives a fundamental understanding of the empirical hydrology methods used to calculate runoff and a brief for 2D denominational. This review found that Hydrology Modelling is based on a) Loss Methods, b) Direct Run-off, and c) 2 Dimensional. This review concluded that the popular hydrology models applied in different environments are the Hydrologic Engineering Center-Hedrologic Modeling System (HEC-HMS) and Soil Water Assessment Tool (SWAT). Also, Hydrologic Engineering Center-River Analysis System (HEC-RAS) sites are at the top of the hydraulic water depth (1D) and water Distributed (2D) models to assess flood plans. Hydrological models became a postnatal application to understand flood risk in both gauged and ungauged catchments.

“…The R-square values for the wet and dry seasons are 0.72 and 0.85, respectively. According to Gholami [40], to overcome the limitations of the calibration and validation of the model, the flood mapping will be more efficient by using the flood marks in the tree trunks. The precipitation depth from NOAA for 25-, 50-, and 100-year return periods is then used as input data in the model's frequency storm tab for the meteorological station defined.…”

This research creates a framework for modelling the rainfall-runoff process using satellite precipitation data and a floodplain map in ungauged urban watersheds. The combined effects of urbanisation and climate change over the past few decades have increased the number of flooding incidents. Accurate prediction of the flood-prone zone is crucial for policymakers and system managers to build the watershed's resilience during catastrophic flooding events. Precipitation and runoff data are crucial for hydraulic and hydrologic analysis and for identifying flood-prone areas. However, it is difficult to obtain precipitation and discharge data for hydrologic analysis in data-scarce regions. In this context, this research employs satellite precipitation products for rainfall-runoff analysis, which is subsequently utilised in a hydraulic model to delineate a flood-prone zone in an ungauged watershed. The Hydrologic Engineering Centre-River Analysis System (HEC-RAS) and Hydrologic Modelling System (HEC-HMS) models were utilised in the study region to simulate and analyse interactions between rainfall, runoff, and the extent of the flood zone. Setting up and calibrating the HEC-HMS model using a satellite precipitation product is required for the dry and wet seasons. For the wet and dry seasons, HEC-HMS gets validated with an R-square value of 0.72 and 0.85, respectively. Three types of simulations were conducted in the calibrated HEC-HMS model to create the hydrograph with 25-, 50-, and 100-year of rainfall return periods. Finally, the one dimensional HEC-RAS model generates a flood inundation map for the pertinent flooding occurrences from the acquired peak hydrograph. By comparing the values of the specified return periods, the produced flood map depicts the affected area during various return periods of flooding events and provides a quantifiable display of inundation extent percentage (IE%).
