In order to be able to take relations and interactions into consideration a simulation model for river basing management needs to represent all relevant objects and processes within the natural system. In modelling this is implemented through system elements. In order to model different systems the following elements are needed:

Water-power plants are not a system element themselves they occur in combination with other elements. In order to function a water-power plant requires a reservoir. If the water-power plant is a run of river power plant at a certain channel cross-section this section of a channel should be defined as a reservoir.

The content of the following table gives an overview of the most important inputs and outputs as well as the characteristics of each element.
