Euro-limpacs Deliverables


A progress report on the WP6 integrated catchments database and preliminary GIS assessment of the data

This report describes the meta−data collated as part of Work package 6, Task 6.1, and their preliminary analysis. The meta−data database represents a major project resource and analysis of the data using a Geographical Information System confirms there is a sound basis for the modelling activities in WP 6 and that available data−sets are appropriate for the application of the component and chained models to assess the impacts of climate change and the mitigation strategies throughout Europe. The results of the analysis confirm the following:

i) the work package 6 study areas have been monitored for a wide−range of pollutants, including those central to Euro−limpacs: sediment, nitrogen, phosphorus, carbon, mercury;
ii) together the study areas cover the key climate types found in Europe;(br /> iii) both small research catchments and large river−systems, appropriate for the scale of catchment−management, are included;
iv) the study areas include a range of rivers, lakes and wetlands, and systems that include at least two of these freshwater types;
v) the available data cover a range of temporal (daily to decadal) scales appropriate for the study of catchment−scale factors and processes controlling the hydrological, water−quality a nd ecological behaviour, the development of the component models and model−chains, and the replication of model applications across Europe to assess seasonal and inter−annual impacts of global change on the ecosystem;
vi) however, high−frequency (daily or sub−daily) water chemistry monitoring for quantifying extremes is sparse.
The meta−data were collated over the first year of the project using a web−interface hosted on the Euro−limpacs web−site. Meta−data can be added, updated, removed and viewed using this interface ( Some questions remain regarding null values and zeros in the water chemistry summaries, and the precise methods used to measure phosphorus. These questions will be addressed in year 2 (Task 6.1).
