Incorporating stakeholder concerns in Land Information Systems for urban flood management

Abstract

Urbanization increases urban flood. This urges hydrologically and economically planned land development decisions. When decision making, incorporation of hydrology model with GIS is a common practice due to the requirements of accuracy and efficiency. Nevertheless, GIS and hydrology incorporated tools (HydroGIS) should facilitate stakeholder concerns for practical implementation. But there were no single tool and developing such becomes a hard undertaking due to the absence of proper guidelines. Therefore, the present work is to identify the stakeholder concerns and incorporate those in a HydroGIS tool (Land Information System) for Urban Flood Management. For the purpose, it identified and verified the stakeholder concerns through a literature survey and stakeholder discussions. Then, incorporated those into the tool and evaluated the achievement. Present work identified and incorporated the stakeholder requirements; such as the requirement of an automated tool, User friendliness using novel GIS-GUI development guidelines, development of the software using a novel approach of development, security through novel security mechanism and, integrating the hydrology-GIS model using a suitable base software. The systematic incorporation of such requirements into the tool shows the growth in user satisfaction from 48% to 92%. The accurate recognition and incorporation of stakeholder requirements lead to the successful HydroGIS tool in urban flood management.
