About Otto Weiler

Since 2010, Otto Weiler (1964) has been working intensively on salt intrusion through navigation locks and ways to reduce it. Relevant projects included the development of the IZZS (Innovative Salt-Fresh Separation) for the Krammer Locks and the Selective Extraction at IJmuiden as a mitigating measure in the construction of the new large Sea Lock IJmuiden. Salt intrusion at lock gates is attracting increasing attention, partly due to the dry summers in recent years. Due to a shortage of fresh water, there is then too little water to flush out the salt, including on the North Sea Canal and the IJsselmeer.

As part of knowledge development in that area, building on the work of colleagues, he developed a calculation method to quantify salt intrusion based on dimensions, lock operation and possible measures to reduce salt intrusion. This calculation tool is increasingly being used. On the one hand for exploring the impact of climate change and the measures to be taken in response, and on the other in the operational management of freshwater systems on salinity.
