Welcome to the Pasternack Lab.
We help society manage and restore hydrogeomorphic processes in support of enhanced ecosystem functioning. We do this through a combination of (i) basic physical and ecological science to understand how the naturally complex landscape works, (ii) development of methods and software for designing more natural, functional environments, and (iii) technology transfer to get concepts, methods, and results into the hands of practitioners, regulators, and stakeholders. Research is also balanced with teaching, service, and outreach.
This website's development was supported by the USDA National Institute of Food and Agriculture, Hatch project number CA‐D‐LAW‐7034‐H.

Latest Teaching Developments
Classes that will be taught in 2022-2023 will include SAS004 (fall) and a new River Conservation course in winter 2023.
HYD151 was discontinued as of 2020. It was a great journey over 21 years, but now I have created new class to teach about virtual field methods and river conservation. I hope to pass the torch of the field methods class on to the next generation of colleagues.
Latest Lab Group Developments
- in 2022 there is 1 postdoctoral researcher, 3 PhD students, 2 MS students, and 1 undergrad working in our lab group. There will be a lot of turnover for fall 2022.
- Recent articles have been characterizing channel types in California, showing applications of machine learning to predicting channel types, presenting new software for geomorphic and ecohydrualic applications, and synthesizing currnet knowledge about river restoration.
Latest Research Developments:
The schematic below shows the large scope of research the Pasternack Lab was undertaking heading into the pandemic and through 2021. Several of these lines have now finished. In some cases their completion is a endpoint whereas in others there remains strong interest and opportunity to continue pushing the scientific frontier.
Looking beyond the schematic, here is a list of some of the broad research questions we are actively pursuing at this time, in no particular order:
- What are the details of the mechanisms by which rivers change their shape and to what extent does hydrology and topography control these mechanisms?
- What physical habitats do aquatic and riparian organisms need and how do those habitats change as a funciton of river discharge and topographic change?
- What is the role of organized variability in river form, process, and links with ecology?
- What is the geomorphic sustainability and ecological functionality of commonly engineered river restoration features?
- What environmental flows should be released to support rivers of different types?
- How can we design more natural rivers for the many situations in which we need to build rivers from scratch or significantly recontour existing rivers.
The above list is not all-inclusive, but it highlights the big picture of the scope of work we are actively doing.
Links to all projects can be found on the Projects web page. Here are some direct links to some projects we are doing right now.
