Short summary
Classical statistical methods for flood frequency estimation assume flooding characteristics do not change over time. Recent focus on climate change has raised questions of the validity of such assumptions. Near-natural catchments are used to focus on climate (not land-use) change, investigating the sensitivity of trend estimates to the period of record. Some key statistics were very sensitive, but conclusive spatial patterns were not found. Smaller floods were most affected by these trends.
