Two factors contribute to fluctuations in groundwater
levels - groundwater abstraction and changes in
infiltration.
While withdrawals are an easily definable factor due to
pumping registration, the actual infiltration over time
can be determined with limited accuracy
problem of climate simulation

1. Scenario 01 – default state for scenarios 02-06, average infiltration, consumption in 2017;;
2. Scenario 02 – average infiltration, which decreases by 2 mm/year every year, ie by 60 mm in
30 years, withdrawals in 2017;
3. Scenario 03 – average infiltration, which decreases by 3 mm/year every year, ie by 60 mm in
90 years, withdrawals in 2017;
4. Scenario 04 – annual infiltration 2013 - 2017 reduced by 5 mm for each year, ie the infiltration
is 201 mm lower in 2019 than in 2013, in 2020 the infiltration is 5 mm lower than in 2014, etc.,
withdrawals in 2017;
5. Scenario 05 – average infiltration, maximum allowed withdrawals
6. Scenario 06 – annual infiltration 2013 - 2017 reduced by 5 mm for each year, ie the infiltration
is 201 mm lower in 2019 than in 2013, in 2020 the infiltration is 5 mm lower than in 2014, etc.,
maximum allowed withdrawals
7. Scenario 07 – default state for scenarios 08-10, average infiltration, withdrawals in 2017;
8. Scenario 08 – average infiltration, pumping of maximum allowed withdrawals;
9. Scenario 09 – average infiltration, pumping of 85% of maximum allowed withdrawals;
10. Scenario 10 – average infiltration, pumping of 115% of maximum allowed withdrawals.

Natural resources in the Hřensko area were verified by a
model at 1481 l/s. The exploitable resources, which ensures
that the hydrogeological structure is not overloaded, is 623
l/s. With current consumption of 105 l/s, the reserve is 518
l/s.
The model stress test proved that in the area of Hřensko it
would be possible to increase the pumping of the maximum
permitted consumption up to 115%, ie on the Czech side to
125.9 l/s and at the same time on the German side to 80.5 l/s,
including dry periods.

Natural resources in the Děčínský Sněžník area were
verified by a model at 724 l/s. The exploitable resources,
which ensures that the hydrogeological structure is not
overloaded, is 321 l/s. With current consumption of 78 l/s,
the reserve is 243 l/s.
The model stress test proved that in the area of Děčínský
Sněžník it would be possible to increase the pumping of the
maximum permitted consumption up to 115%, ie on the Czech
side to 106.8 l / s and at the same time on the German side to
13.8 l / s, including dry periods.
