Talk:Piotr Parasiewicz

Request to replace the article with a sourced, neutral rewrite

I am Piotr Parasiewicz, the subject of this article, so I have a conflict of interest. I am not asking editors to rely on my private CV as a citation. I used it only to identify omissions and then supplied publicly accessible institutional and scholarly sources. The current article contains citation errors, unsupported living-person claims, and an incomplete account of my work at BOKU in Vienna.

I request that the article be replaced with the sourced draft below. In particular, the proposed version restores the 1988–1999 BOKU period, including my research and teaching appointments, early work on river-habitat surveying, the DVP instrument, hydropower-peaking research, and participation in the Austrian Network for Environmental Research.

== Research ==
Parasiewicz's early research at BOKU addressed the measurement and modelling of river habitat, hydropower impacts, fish passage and river restoration.<ref name="Geodesic-1996" /><ref name="DVP-1999" /><ref name="Bregenzerach-1998" /> This work provided a foundation for his later development of MesoHABSIM. In 2001, he introduced the method as an approach for applying physical-habitat models at whole-river scales, changing the analytical resolution from microhabitats to mesohabitats.<ref name="MesoHABSIM-2001" /> A 2007 paper revised the method to combine assessments of ecological integrity with quantitative simulations of physical-habitat distribution at watershed scale.<ref name="MesoHABSIM-2007">{{cite journal |last=Parasiewicz |first=Piotr |title=The MesoHABSIM model revisited |journal=River Research and Applications |volume=23 |issue=8 |pages=893–903 |year=2007 |doi=10.1002/rra.1045}}</ref>
