Investigating the hydrologic regime of 195 rivers in Australia revealed three types of flow seasonality. At some stations, the wettest period occurs during one particular season (winter or summer), whereas at others, similar flows are observed all year round.
Sounds triggered by events The map below shows the main flood events of 2019, their duration and the size of the flood-affected area (for further discussion of this dataset, see the post Sonification techniques: mapping data to pitch and volume).
Plotting hydrologic regimes Most hydrologic studies start by determining the average quantity of water in rivers and how it is distributed throughout the year.
Mapping data to visual or auditory properties A common visualization technique is to use the color or size of symbols to represent data. The bubble map below shows an example.
