Abstract

This study used streamflow recession analysis to assess changes in groundwater–streamflow relationships using streamflow data. The groundwater response to climate and Normalized Difference Vegetation Index (NDVI) changes was considered as a variable in the recession analysis. The results could thus be compared with the integrated impact to assess the consistency of these effects on the catchment discharge processes. The results showed that the recession characteristics are linked to regional topography and streamflow condition. Variation of storage–discharge sensitivities in most catchments was not linked to the variation of groundwater due to the lower capacity of groundwater contribution. The quantified impacts aided in assessing the relationship between climate, land cover, groundwater storage and discharge. This study provides a simple explanation of the effects of environmental coevolution on storage–discharge processes.
