2. Measures aimed at water retention in the catchment are recommended. Changes
in the conditions of water circulation and outflow should be towards its retention
in the soil and bedrock, leading to a decrease in surface runoff and an increase
in exploitable resources in catchments.
3. To prevent the decline of lakes is necessary to prevent the intensification of
the sedimentation process by preventing a decrease in the water levels and
accumulation of sediments.
4. Lakes in river valleys are subject to dynamic disappearance processes and
require detailed bathymetric, hydrochemical and hydrobiological studies.
5. There is an urgent need to save and preserve springs and indicate the ways and
directions of necessary actions that is interesting for environmental protection
services, local authorities and social organizations dealing with the protection
of environmental and cultural heritage.
6. The public interest in healing water, thermal water, and highly mineralised water
(brines) has been growing considerably for some time. All these factors make
scientists and specialists show greater interest in deep water resources, also in
the form of a mathematical description of phenomena occurring in the stagnant
water zone, which is virtually outside water circulation.
7. The observed transformations of the regime type in the winter North Atlantic
Oscillation phases against the background of average conditions are understandable and indicate the possible destabilization of the characteristics of the flow
regime of many rivers in Poland in the changing climatic conditions caused by
the varying intensity of the macroscale type of circulation.
8. Further research of flow seasonality in two big polish rivers – the Vistula and
the Oder should be carried out. It will allow to check whether the introduced
changes do not disturb the natural regime of these rivers. These studies will be
helpful for decision makers in the Ministry of Maritime Economy and Inland
Navigation as well as for ecological organizations monitoring changes in rivers.
9. Good knowledge of low-flows and their determinants may effectively support
the tools and strategies of optimal reduction of drought results, its prevention
and prediction. Advanced recognition of river low-flow regime is very important
for water balance structure and may be crucial for identification of quantity and
dynamics of available water resources.
10. Practical conclusions, especially those concerning regional barriers for development and regularities of the duration and range of hydrological drought can
significantly expand water management aimed at mitigation of drought effects
at the national and regional scale.
11. The “Flood Marks” (www.openhydrology.org/maps/flood_mark) project seems
to be a step in the right direction to information about the high water marks
during floods. Its strength is the utilization of the popular and still growing
internet community of OpenStreetMap users.
12. Flood potential index can be used in regional plans of flood risk management.
Flood potential index can be used for comparison of catchment reactions to rain
at different regions.
