G2 Soil erosion data
| Subject | Erosion data for Strymonas river (14,500 km2), located in South East Europe (Greece / Bulgaria). |
||
| Keywords | Erosion, G2, modelling |
||
| Publisher | JRC and Aristotle University of Thessaloniki |
||
| Status | Final |
||
| Description Objectives | G2 model is a new generic model for erosion, resulted from the cooperation of JRC/IES/Land Management & Natural Hazards Unit/SOIL Action and the Lab of Forest Management and Remote Sensing of the Aristotle University of Thessaloniki in the framework of geoland2 project. G2 estimates soil loss (in t/ha) from sheet and interril erosion caused by splash and runoff, on a month-step basis and on a landscape scale. G2 employs harmonized standard input data from European and global databases, such as the European Soil Database (ESDB), the Topsoil Organic Carbon (TOC), BioPar products of geoland2, the SPOT imagery, and the ASTER DEM datasets. This makes it appropriate for implementation throughout Europe on a 1:500,000 cartographic scale (MMU=10 ha). G2 is a dynamic model, as it takes account of contemporary changes of rainfall erosivity and vegetation retention. Based on the empirical USLE-family models, it needs calibration for rainstorm erosivity, while vegetation retention is based on biophysical parameters derived with remote sensing (BioPar products). G2 is a feasible, easy to run, data-driven model. At the same time, it is realistic, as it has been showed by preliminary validation with experimental erosion and sediment measurements in the cross-border river basin of Strymonas/Struma in Greece and Bulgaria |

| Abstract | G2 model is a new generic model for erosion, resulted from the cooperation of JRC/IES/Land Management & Natural Hazards Unit/SOIL Action and the Lab of Forest Management and Remote Sensing of the Aristotle University of Thessaloniki in the framework of geoland2 project. G2 estimates soil loss (in t/ha) from sheet and interril erosion caused by splash and runoff, on a month-step basis and on a landscape scale. G2 model has been applied in the cross-border basin of Strymonas river (14,500 km2), located in South East Europe (Greece / Bulgaria). The data of Strymonas application are provided for free in raster format (Grid and TIFF), in the ETRS89 LAEA Coordinate System; temporal coverage: Monthly for the period 1997-2006. |

| Description Background | G2 model has been applied in the cross-border basin of Strymonas river (14,500 km2), located in South East Europe (Greece / Bulgaria). Model parameters were calibrated with measured data and the results were verified with erosion and sedimentation figures from previous research. The study confirmed that monthly erosion mapping would identify the critical months and would allow erosion figures to be linked to specific land uses. The results also showed that the model could become the basis for a functional pan-European service for soil erosion monitoring on a regional scale. |
