Visualisation of spatial uncertainty in hydrological modelling

Abstract

Uncertainty in hydrological modelling is often associated with model structure or calibration coefficients, and little consideration is given to the visualisation of uncertainty in either input or output data. As hydrological modelling is often a component of landscape design, there is continuing interest in the visualisation of uncertainty in model inputs and outputs, which could include catchment size or landcover (spatial inputs), and the subsequent impact on uncertainty in model predictions (such as streamflow). In this paper, inputs and outputs associated with hydrological models are discussed in the context of spatial uncertainty and how this information may be presented to users by me..
