A methodology for carrying out a sensitivity analysis

The success of an urban stormwater project depends not only on the technical, legal and economic feasibility. As least as important is the water manager is able to make a connection between stormwater and urban dynamics. Especially when he or she aims at source control. Ambition Reflection is about the manager�s ability to successfully implement stormwater measures in the urban context. The fingerprint is a web based tool in Hydropolis that gives the user the opportunity to find out his attitude (goals, philosophy, perception and position) towards USWM related to urban dynamics.

Therefore, we distinguish three types of attitudes: basic water management, functional water management and contextual water management. For basic water management the water management is directed inward. An attempt is made to optimize the water system to minimize any inconvenience at the boundaries of the system being managed. In this attitude the interaction between system and context is minimized.

Functional water management makes connections with the context by freezing the context in functions (such as ecology, nature and recreation). The aim of functional water management is to integrate the system as well as possible within the defined functions. There is a question of unilateral influencing of the system by the context. Contextual water management, on the other hand, really confronts the context. The context is not frozen in functions, but the continuous interaction between system and context plays a central role. And it is in this interaction that source control can be implemented successfully.
