Fun with dendrograms
A dendrogram is a way to visualise objects organised in a hierarchy. It looks like a tree where: the leaves represent the objects of the dataset; the branches link similar leaves according to a given criterion.
How Australian rivers can be grouped into 4 main hydrologic regimes
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.
Exploring the hydrologic regime of 195 rivers in Australia
Plotting hydrologic regimes Most hydrologic studies start by determining the average quantity of water in rivers and how it is distributed throughout the year.
