UNIVERSITY PARK, Pa. As communities look to restore their waterways after centuries of human alteration, many are turning to nature for inspiration.
River restoration projects utilizing nature-based solutions, like the Big Spring Creek restoration project in Cumberland County, Pennsylvania, revitalize their ecosystems by reintroducing natural materials like wood and debris into their design. These materials over time often amass into complex, porous structures that offer many ecological benefits but are not well understood, according to Xiaofeng Liu, associate professor of civil engineering and co-hire of the Institute of Computational and Data Sciences at Penn State.
Thanks to a $297,791 grant from the National Science Foundation, Liu will examine the nature-based solution of engineered log jams to quantitively describe the flow and sediment dynamics around these systems.

These are expensive projects, but theres not too much of a scientific understanding of what really is going on, Liu said. How does the water move around the in-stream structures? How does it carry solute and sediment?
In contrast to restoration projects that use concrete and steel, water and sediment are able to flow through the pores in the nature-mimicking structure, creating unique turbulent flow patterns.
The porosity creates more complexity and richness in the flow features, Liu said. Water can go through them and around them. This complex flow field is important for the functionality and longevity of the structure.
As these flow patterns develop, sediment is transported and sometimes filtered by the wood and debris. This sediment movement around the log jam can also result in scour holes that can become habitats and shelters for fish, a desirable characteristic of nature-based solutions. However, Liu noted, these holes develop differently than they would around traditional impervious structures, such as bridge piers, and can have an effect on the longevity of the structure.
For engineers looking to install an engineered log jam, the lack of fundamental understanding of these complex flow patterns means relying on educated guess. Formulas that currently exist to predict scour hole size and depth do not account for porosity.
Its a lot of trial and error at this stage right now, Liu said.
Based on preliminary results, Liu developed his own formula using porosity as a parameter to help predict scour hole size for nature-based solutions. He will test this by developing a high-fidelity 3D model to simulate the flow and sediment dynamics in a river containing an engineered log jam.
Mathematically resolving all of the geometric details found in an engineered log jam requires a lot of computing power, so Liu will rely on the ICS-ACI, Penn States high-performance research cloud, to run the simulations.
The mathematical equations in the model are just the descriptions of the physical processes in this problem, Liu said. Flow carries the sediment and creates a hole. When holes are enlarged, water has more space to go. Our model describes this co-evolution with the presence of a complex restoration structure.
Liu will also run physical experiments in a 15-meter flume, an artificial water channel in the Penn State Hydraulics Laboratory, using scaled-down engineered log jam models. After each experiment, he will drain the flume and use a laser to scan the bed. The results of the flume experiments will then be cross-referenced with the computational model and with field measurements to validate results.
If Liu succeeds and is able to establish a fundamental understanding of the physical processes occurring around these structures, future research will then be able to link that to ecological processes, which should give scientists a better idea of how well these solutions are achieving their sustainability goals.
Thats the final goal, Liu said. Hopefully, with the introduction of nature-based solutions, nature can start to re-establish itself. When nature is working, you dont need too much human intervention.
