Abstract
Climate and land cover are the main regulators of discharge formation. We combined here 5 alternative land cover case with 2 different precipitation scenarios. Land cover scenarios are: (a) present land cover according to CORINE 2006 maps, (b) ICES scenario at 2050, (c) IMAGE scenario at 2050, (d) cementification scenario C1 and (e) cementification scenario C2. The ICES and IMAGE scenarios are based on consideration of economy and population growth, cementification scenarios 1 and 2 are intended as exemplificative what-if scenarios for urbanization of rural areas. Precipitation is modelled as (a) the observed one and (b) increasing of 10% the average value. Peak flood probability distributions are analytically for each of the 10 land cover-climate combinations. The case study is the Secchia river basin in Emilia Romagna region. Results show that in absence of changes in the precipitation regime, the peak flood associated to low return period (
