GTN-R represents a crucial component of the Global Runoff Data Centre (GRDC), which has been operating under the auspices of the World Meteorological Organization (WMO) since 1988.

Use knowledge of the hydrological cycle to explain specific flood events, with reference to maps and hydrographs.

Prolonged droughts, wildfires and water shortages. Torrential downpours that overwhelm dams and cause catastrophic flooding.

Water constantly moves between the Earth and its atmosphere. But that system — called the hydrological cycle — is speeding up as global temperatures get hotter, primarily due to the burning of ...

Use the key terms featured in a river basin case study. Consider the effect of seasonal differences in rainfall and relate this to changes in river levels and risk of flooding. Students could ...
