The hydrological effects of varying vegetation characteristics in a temperate water-limited basin: Development of the dynamic Budyko-Choudhury-Porporato (dBCP) model

•Incorporated dynamic ecohydrological processes into Budyko–Choudhury–Porporato (BCP) model.•Above, linked to typical soil water ‘bucket’ model, results in the dynamic BCP (dBCP) model.•dBCP allows Choudhury’s n-value to be calculated dynamically.•Assessed actual evapotranspiration (E) changes for different vegetation cover fractions.•Analytically assessed the sensitivity of E to changes in P, Ep, effective rooting depth and storm depth.
