I have launched two discussions earlier.

1. Who are the stakeholders in Flood Management tools? : The major components should be considered when hydro-GIS-stakeholder flood management tools? at https://www.researchgate.net/post/Who_are_the_stakeholders_in_Flood_Management_tools_The_major_components_should_be_considered_when_hydro-GIS-stakeholder_flood_management_tool

2. Discussion on Debriefing of the above question at https://www.researchgate.net/post/Debriefing-Answers_for_the_question_Who_are_the_stakeholders_in_Flood_Management_tools

By both question and discussion, I confirm that the hydro model and GIS model should be integrated to a single model called hydrogis model, and such work is done by a modeler - may be a software developer or hydro/gis modeler. then such a tool provides the interaction between decision-makers and the recipients in the urban flood management scenarios. then when develop a hydrogis model to urban flood management the following components' concerns should be considered.

1. Hydro Model

2. GIS model

3. The modeler

4. The recipients

5. The Decision-makers

However, this happens before the COVID situation. therefore I requested you all to give your views on the sufficiency of the components. Thank you all
