The hydrological significance of the rainfall time-space distribution on a flood hydrograph is well known and assessed in literature. The density of the rain gauge network and the pattern of areal and temporal distribution of rainfall can affect the results of the calibration and the validation of distributed rainfall-runoff modeling. The aim of this work is to assess the implications of changing the composition of rain gauge network, successively reducing the number of gauging stations, while maximizing the performance of the hydrological model.

Abstract
The hydrological significance of the rainfall time-space distribution on a flood hydrograph is well known and assessed in literature. The density of the rain gauge network and the pattern of areal and temporal distribution of rainfall can affect the results of the calibration and the validation of distributed rainfall-runoff modeling. The aim of this work is to assess the implications of changing the composition of rain gauge network, successively reducing the number of gauging stations, while maximizing the performance of the hydrological model. This case study is based on the Mignone river basin (500 km2), which is located in Central Italy and equipped with 4 rain gauges.| File | Dimensione | Formato | |
