At this moment you will receive a score 6 out of 6 and you will see which answers are correct. Besides seeing which answer is correct you also see the fully correct answer of the questionnaire maker.

Results

#1. 1. Through which countries does the Meuse River flow?

The Meuse River flows through France, Belgium and the Netherlands. Its source is in France, Pouilly-en-Bassigny, and it flows into the Rhine-Meuse delta, North Sea, in the Netherlands.

#2. 2. How long is the Meuse and how large is its catchment area?

The Meuse River is 905 kilometres long and has a catchment area of 34,548 square kilometres. The average discharge is 357 m³/s.

#3. 3. Where and how can plastic litter be entered?

Plastic litter can enter the Meuse River anywhere. The entry paths are diffuse through wind and rain (surface runoff), but also point based through storm- or wastewater discharges.

#4. 4. How many tributaries (rivers with a length > 80 km floating into the Meuse) does the Meuse have and how can plastic litter get in there?

The Meuse River has ten tributaries each with a length > 80 km (from source to sea: Chiers, Semois, Lesse, Sambre, Ourthe, Amel, Rur, Niers, Zuid-Willemsvaart, Dommel). Similar to the Meuse plastic litter can enter the tributaries anywhere by wind or rain, surface runoff and stormwater and thus they act as entry paths for riverine plastic litter in the Meuse.

#5. 5. In which years highwaters were responsible for numerous litter items that accumulated along the river banks?

There were two very strong highwaters that have led to flooding along the whole river catchment in the years of 1993 and 1995. During floods, which happen every winter (and sometimes in other seasons after days of heavy rain), transported material, like plastic litter, can predominantly deposit on floodplains.

#6. 6. On average, littering into the environment amounts to 2.4 kilograms per capita per year in Germany. If 5% of this are assumed to be discharged into the Meuse each year, what would be the potential input from the 9,000,000 inhabitants near the watercourse?

This leads to 0.12 kilograms of litter per capita which results annually in 1,080,000 kilograms (1,080 tons) of litter that enters the Meuse River system. Other investigations estimated an annual volume of 100 – 1,000 m³ of fine macroplastic and 10 – 100 m³ of coarse macroplastic contribution in the Meuse River.
