History-long discussions on the IWRM are making the idea that the recipient stakeholders' poor participation is obstructing sustainable decision-making in urban flood management. Early works found dozens of negative reasons for the practical incorporation of recipients' perspectives in administrative decision-making. However, it found there is no in-depth study has been carried out to inductively explore the present situation. Then this work explored the present status of stakeholder integrations in IWRM. It carried out abductive research using a sequential multi-phase approach of the mixed method. It employed modified constructivist grounded theory, documentary research, and survey strategies to find and verify the main components and their integration depths in the scientific and management model of urban flood management. For the component identification, it studied the GIS2MUSCLE urban flood management tool, 4 hydro-GIS integration models, and 247 works of research and for calibration, it utilised 21 experts. The average integration depths among the components were calculated using 32 research works employing WAP of MCDA and evaluated the result with 70 experts using MCGDM. The present work found there are five main components in the urban flood management model namely, Hydro modellers, GIS modellers, HydroGIS modellers, decision-makers and recipients and at the present, all the components are integrated with low (value 2 out of 5) status. Further, those components are in two groups, scientific modellers (Hydro and GIS modellers) and management modellers (decision-makers and recipients) while HydroGIS modellers are developing the entire flood management model integrating the perspectives of both groups. Nevertheless, the research found that they are more biased toward the management model and maintain very low (0.94 out of 5) integration with the scientific model. Therefore, this work concludes by stating that in the present IWRM situation it should pay more attention to integrating scientific modellers’ perspectives when satisfying the recipients' requirements.
