Unesco Working Group on Cultural Changes and Hydrological Cycle Influence

Micro-climatic changes are more useful to study than long-term climatic changes.

The minimum observational program for an expected geomorphological change includes only flow and precipitation measurements.

For hydrological prediction in representative basins, the observational program should specify whether long-term or short-term prediction studies are intended.

The observational program for representative basins used for hydrological prediction is the same regardless of whether daily or weekly mean discharges are required.

The water balance elements are not part of the observational requirements for an expected geomorphological change.

Experimental basins are used for hydrological prediction studies.

Soil cultivation methods are not relevant to the observational program for an expected geomorphological change.

The influence of the hydrological cycle is not considered in the observational program for an expected geomorphological change.

The observational program for representative basins used for hydrological prediction is the same regardless of the prediction time frame.

Geomorphology measurements are not part of the minimum observational program for an expected geomorphological change.
