Abstract

In 1998 the JRC, Ispra, initiated a specific research activity to design and implement a Catchment-based Information System (CIS). The purpose of the CIS is to provide a quantitative response to agro-environmental topics in the framework of an operational activity - using catchments as management units and covering the area of the European Union.

For the delineation of catchments and sub-catchments a "stream burning" method was applied. This necessitated the development of a European river network, starting with a commercially available data set, which was developed to ensure connectivity of rivers within a river system, separation of different systems in the raster representation and a single defined outlet. The flow network generated by the stream burning procedure was then used to delineate 10 catchment layers through repeated sub-division.

In general, the CIS catchments compare favourably with other data from other sources. The catchment data were used in combination with additional data layers of the CIS to calculate a nitrogen balance for agriculture in EUI5.
