Purpose
This challenge handled the ability to compute annual water discharges for each river bordering the sea basin, inputs of fresh water, sediment loading, total nitrogen and phosphates (time series), to assess whether the available marine data sets that had been available and appropriate to the use case, as well as to indicate gaps in the EU data collection framework.
Abstract
The River Inputs challenge attempted to estimate, for each river bordering the sea basin, the time series of annual inputs:
- Mass of fresh water discharged and temperature
- Sediment load
- Fluxes of total nitrogen and phosphates
- Biota to sea as eels and salmon (both inwards and outwards, recruitment and escapement).
Nine different products were considered in order to provide an estimate of the amount of monitored rivers regarding the total number of rivers. (A river was defined by either by its river outlet (geographic position) or by the basin district, a region or a whole country).
