Abstract
A spatially-distributed hydrological model based on Topmodel is used, without calibration, to simulate flows and soil moisture variation at the Mahurangi basin, New Zealand. Inconsistencies caused by measuring the saturated hydraulic conductivity of the soil at one spatial scale and estimating the distribution of the topographic index ln(alpha/tanbeta) at a different scale, are discussed. The results indicate that estimates of hourly flows using an uncalibrated model are practical, but that less certainty can be placed on the simulated soil moisture values.
