Spatial dataset consisting of annual nutrient diffuse sources emissions for 2005-2012 estimated at freshwater functional elementary catchments level and considered in the model GREEN (Grizzetti et al., 2012; March 2019 version). Diffuse sources of nutrients comprise agriculture (mineral and organic fertilization), nitrogen fixation by crops and in soils, nitrogen atmospheric deposition, phosphorus releases from natural areas, and scattered dwellings. The river basin hydrological data model is based on Catchment Characterisation and Modelling
(Vogt et al., 2007; https://data.jrc.ec.europa.eu/dataset/fe1878e8-7541-4c66-8453-afdae7469221) as well as the
European catchments and river network system (Ecrins , version 1 - European Environment Agency)

Web-mapping application displaying geographic roll-up / drill-down of diffuse sources to freshwater network over administrative and hydrological geo-hierarchies trough time (year 2005 to 2012).
Data, stored at granularity of Ecrins functional elementary catchments (FEC), are summarized over 4 level administrative, 3 level hydrological as well as 2 level official river basin district hierarchies. Map viewer defaults to nitrogen diffuse sources over administrative areas. Upon different layer selection it is possible to display different nutrient types over different hierarchies. Hierarchical level display is constrained to chosen zoom level. Attribute access provided upon mouse clicks on active map layers.
To navigate the time dimension use the time slider widget available in the application
File geodatabase distribution containing the following classes:
1. Main table class greenFecDiffuseSourcesRef_vrsMar2019 containing records of annual diffuse sources emissions (nitrogen and phosphorus period 2005-2012) for Ecrins functional elementary catchments.
2. Feature class C_ZHYD containing a subset of ECRINS (EEA) functional elementary catchment geometries to be linked to previous table class via primary/foreign key ZHYD
