Introducing seasonal snow memory into the RUSLE

The University of Stuttgart have incorporated seasonal snow memory into the Revised Universal Soil Loss Equation (RUSLE) and combined it with the SEdiment Delivery Distributed (SEDD) model in a recent scientific publication. The inclusion of snow-related processes, especially the separation of non-erosive snowfall from erosive snowmelt, was found to greatly enhance model accuracy. These results represent a major improvement for estimating suspended sediment loads, especially in data-sparse regions, further enhanced by the use of freely available satellite imagery and climate reanalysis datasets. These results are important for DIRT-X applications as long-term predictions of bathymetric change, necessary when modeling climate change scenarios, will require an objective calculation procedure for the sediment load as a function of a catchment’s specific characteristics and hydroclimatic features.

DIRT-X field excursion 2022

Before the GA in the end of June we participated in a field excursion.

Our first stop, after an amazing boat ride, was at NTNU’s Sletvik biological field station where we learned about their teaching/research in the bay of Hopavågen with special hydrological features due to its narrow inlet from the sea. Read more about Sletvik here.

Our second stop was at Follsjoe Dam, operated by Statkraft. We learned about new construction work being carried out to bolster the dam according to new regulations. Dams in Norway are reviewed every 15 years and checked for compliance with current regulations. This dam is special due to the chosen method for bolstering the dam (riprap), which is human-placed rock material to protect the dam against erosional processes. Check out the cool pictures below!

Downstream of the dam, a hydraulic structure has been added to prevent wild salmon from entering the river, to control for parasitic infestation.

Our last stop was to see a sediment trapping basin, reducing sedimentation of the reservoir located further downstream. At the photos below you can see basin.

DIRT-X Hybrid General Assembly

The Dirt-X General Assembly will be held June 29-30th, 2022 in Trondheim. It is a Hybrid meeting which means that there will also be participants joining the meeting online. All the work packages are represented in the agenda and there will be a number of topics presented and discussed.

The general focus of the meeting is to:
1. Improved understanding of catchment processes and their interactions with reservoir processes and economics/energy.
2. Climate impact indicators (CIIs) useful to our stakeholders as well as different sectors.
3. Reporting our achievements, coordination among WPs and planning future work.

The day before the General Assembly, on June 28th, there will be a field trip organized by  NTNU.

Stay tuned for an update from the meeting and some photos!
