The scope of this challenge is to check the fitness for use of the current available marine datasets to compute annual water discharges for each river bordering the sea basin, inputs of fresh water discharge as mass and sediment loading, pollution* and biota to sea** (time series), or to indicate gaps in the current EU data collection framework.

The result of the exercise will give an estimation of the number of monitored rivers regarding the total number of rivers (of a given category). And for each monitored river, the information produced  allow to get an overview of the temporal and spatial variability of each characteristic requested to better understand the peculiarities of the Black Sea ecosystems in terms of the strong climatic, geomorphological and cultural contrasts that characterize the Black Sea drainage basin, as well as to identify the major trends that could threat these ecosystems in the near future because of climate change and socioeconomic development.

*  as total nitrogen and phosphates loading

** as eels and salmon

    (both inwards and outwards, recruitment and escapement)

This activity of the EU BlackSea checkpoint project (DG MARE contract n° EASME/EMFF/2014/1.3.1.3/LOT4/SI2.709436) has been executed during the 2015-2018 period of time. The methodology used is identical to all challenges.

  • Perform a literature survey to identify state of the art activities related to the use case and clarify the landscape of monitoring data covering the BlackSea,
  • Specify needs for production and realize the product,
  • Evaluate the adequacy of monitoring data, that is the availability and appropriateness.

The team participating in the challenge is:


Seven products have been requested by the call. The products are listed and accessible from the table given below. All products are representative of the December 2017 status.

The monitored river mouths along the Black Sea basin are: Danube River, Kamtehiya River, Maritza River, Kizilirmak River, Sakarya River, Dniester River, Dnieper River, Don River.

GENERAL DESCRIPTION AND USEFULNESS OF THE PRODUCTS

Hydro-geo-chemical measurements are essential for the interpretation of water quality data and for water resource management. Variations in hydrological conditions have important effects on water quality. In rivers, such factors as the discharge (volume of water passing through a cross-section of the river in a unit of time), temperature, nitrates, and phosphates influence the water quality.

The 7 products and the data are suitable to describe and to evaluate the River Discharge- Temperature – Nitrates – Phosphates trends and the impact on the physical/chemical Black Sea waters properties as well as for water quality monitoring and for water resource management.
