A database for a sediment yield analysis in the Raba River basin (Carpathian Mts)
Description
The database contains results of the modeling study performed for the Raba River basin (Carpathian Mts., Poland) on the sediment yields. Using the calibrated and verified basin created in the DNS/SWAT Macromodel as a baseline scenario, subsequently the climate and land use scenarios were superimposed. The climate change scenarios were prepared using temperature and precipitation projections from the EuroCORDEX regional climate [https://euro-cordex.net/060378/index.php.en] and CMIP5 general circulation models [https://esgf-node.llnl.gov/projects/cmip5/][http://climateimpact.sggw.pl/map/proj/]. The land use change projections were based on the FORECOM project [http://www.gis.geo.uj.edu.pl/forecom/]. To track the sediment yields on the sub-basin level the Raba River basin was divided into 36 units. Impacts of single (hypothetical) and combined climate change and land use scenarios on sediment yield (t/ha and %) for each of these units (sub-basins) are displayed through the selection of database filters. The database consists of six Excel sheets: ‘scenarios’ - a list of scenarios prepared for the needs of the research together with their descriptions, whose impact on sediment yield in each sub-basin can be traced in the next sheets ‘results_plot’ - results of the individual scenarios impact on the sediment yield in the selected sub-basins and/or seasons the data is presented in the form of a pivot column chart. By using the "Select sub-basin or/and season" buttons user can filter any sub-basin and season values ‘changes_plot (t/ha)’ - sediment yield change for each scenario in comparison to baseline scenario in t/ha (functionality like previous sheet) ‘changes_plot (%)’ - sediment yield change for each scenario sediment yield change for each scenario in t/ha in comparison to baseline scenario in % (functionality like previous sheet) ‘sub-basins features’ - location of individual sub-basins, their numbers in the Raba River basin and main features: land use, slopes and soils classes share in the sub-basin area ‘data’ - output from the model for all scenarios (see sheet ‘scenarios’), average values of sediment yield for each season of data from 2005-2017 for 36 sub-basins in t/month
