New BONUS SOILS2SEA publications
Three deliverables are available online at the Website of the project.
BONUS Soils2Sea researchers have published new deliverables, that are publicly available at the project’s website. Deliverable 3.2, published by Refsgaard et al. in November 2016, describes the methodologies used within BONUS Soils2Sea for the up-scaling from small scale models to the Baltic Sea Basin modelling. The objective of the upscaling is to transfer knowledge from local scale models into HYPE for use in simulating the impacts of spatially differentiated measures at the Baltic Sea Basin scale. Basic hypothesis for this attempt is that the small scale models at case study level have sufficient predictability and representativeness to allow model outputs to be used for constraining the large scale model. The report describes five methodological steps that have been applied to groundwater and surface water.
Riml et al. published their report (Deliverable 4.2.) in December 2016 on “Tracer Tests and the effect of solute retention and attenuation on the stream reach scale”. This report describes the first major stream tracer test using radioactive samples. A main purpose of the report is
a) To use the tracer approach for quantification of the effect of remediation actions in agricultural streams
b) To describes the tracer injection methodology, safety aspects a nd evaluation methods.
The report also describes several independently conducted tracer tests using Rhodamine WT in the same stream. All solutes were simultaneously injected in Tullstorps Brook, Skåne, Sweden, using a pump system and concentration vs. time (so‐called breakthrough) curves were determined from water samples taken at five downstream located sampling stations. This report describes the tracer injection methodology, safety aspects of radioactive tracer injections, basic evaluation methods for breakthrough curves and tentative results in the form of certain model parameters. Prior to the main tracer test an extensive field campaign was conducted in Tullstorps Brook with the objective to gain general knowledge about the hydrodynamic behavior of the system, including Rhodamine WT tracer tests and independent measurements of the stream hydro‐morphology. Methodologies and results from this field campaign are also included in the report.
Stelljes described in the report “Updated dissemination material” (Deliverable 1.6, October 2016), the status of the projects dissemination material. It is based on Deliverable 1.3 and therefore follows a similar structure. It includes information about the dissemination plan, dissemination material, the project website, the final conference, and dissemination at BONUS Websites.
