Public data collection and assessment of model reliability

In the previous chapters, different methods for placing monitor devices were developed and tested in the polder system of Pijnacker, described in Chapter 3 and in the river Magdalena, described in Chapter 4 . In Chapter 5 the use of Information Theory concepts was explored in order to maximise the information content about the particular water system. A complementary method that takes into account the subjective beliefs of a decision maker in getting information is presented in Chapter 6 with the maximisation of the Value of Information. The present chapter explores other methodologies to obtain a reliable idea of the state of a water system through public data collection and model validation, which, in turn, looks for an incremental increase in the information content of our water systems.
