Research Interests
Water management involves systems at many different scales. They range from gardens, streets and creeks to large rivers and their catchments. These systems contain many components. Just consider a garden: it contains many different plants, its soil may be a mix of new and old roots, sand and clay with the occasional stone, there may be drainage tubes and possibly a small pond. Its soil contains small cracks and is constantly perturbed by earthworms. While we can study and describe such details, any attempt to take all of them into account when trying to predict whether or not puddles will form on the surface after heavy rain is a lost cause for two reasons. The first is that any attempt to do so will probably end up needing a computer the size of the garden itself. The second is that it is impossible to put all those details into the computer in the first place. Therefore part of the art of water management is the art of leaving things out of your model.
An extreme example of the art of leaving things out is the study of peak discharges in rivers through extreme value theory. In this case entire river system is reduced to a set of numbers, the yearly peak discharges. Extreme value theory provides rules that, under certain conditions, allow us take the peak discharges over the last fifty years and from those to estimate the largest peak discharge to be expected in the next two or three hundred years.
Once we have a model we can hopefully predict events of interest. However, the term water management strongly suggests a wish or need to control what will happen. Suppose there is a reservoir. Such a reservoir may be a "boezem" (see also PolderBoezem systems elsewhere on this site), an artificial lake through which a river flows, or the available storage in a sewer system. Suppose furthermore that its storage capacity will be needed at some point in the future to temporarily store a large inflow because our ability to transport that inflow beyond this reservoir is limited. Such limits might be imposed by maximum safe water levels in the boezem, risk of flooding in the system beyond the reservoir or the level at which water starts to flow from the sewer into the streets. The question of interest is: how to manage this storage? Our ability to predict the future is limited, low and high water levels may be linked to different disadvantages, use of the system to drain the reservoir quickly may be costly or may have varying cost depending on time of day or the day of the week or even on the number of times that system is switched.
As you can imagine the rules for comparing costs, advantages and disadvantages for such a reservoir may not be clearcut. More importantly, their translation into an algorithm (read computer program) may not always produce a system behavior that seems "reasonable" to the people directly affected by the system and those who operate the system.
A major part of creating the models needed and building the control systems that will implement our wishes with regard to system behavior is finding the right tools and using them correctly. These tools can often be found in mathematics. As a mathematician working in the field of water management I try to find these tools and adapt them to the job at hand.
