Methodology to determine financial needs of river structures

In this paper a general methodology is given that can be used to determine the lowest cost intervention strategies of river structures with respect to gradual deterioration processes, their financial needs and the consequences if they are not followed. An example is used to illustrate the type of results possible using this methodology with normally existing data. The methodology is similar to those used in state-of-the-art bridge management systems but is adapted to take into consideration special aspects related to river structures, such as that a river section is composed of multiple river structures and that an intervention performed on a river section normally includes interventions on multiple structures within a section.
