If a set of wastewater treatment plants is to be installed in a river basin within a given time period, an interesting optimization problem is to select the best sequence in which the plants should be built. Two sequencing problems of this kind are d

A problem widely discussed in the field of water resources research is the degree of complexity a water quality model should have if it is used for water quality management. In the present work this problem is investigated by means of an example: An

The sensitivity of dynamic systems to changes of the parameter values can be estimated by two first order methods: either by solving the sensitivity system, or by solving the original system twice with slightly different parameter values. In this pap

The self-purification process in rivers is described qualitatively. Different ways of representing this process by systems of differential equations are discussed. The parameters of the differential equations cannot be measured directly, but must be
