1st Part - The effects of land-use changes on annual gross erosion are investigated through a distributed application of the Universal Soil Loss Equation (USLE) to a wide geographical region in northern-central Italy. The USLE, which was empirically derived for plots and is usually applied at most at basin scale, is implemented in a distributed framework through a discretisation of the study area in elementary square cells. The local amount of annual gross erosion is evaluated by combining several kinds of morphological, pedological and climatic information. The model estimates of annual gross erosion are validated for a land-use scenario dated 1992. Two different historical land-use scenarios of Bologna’s District, a large portion of the study region, are then used to assess how real land-use changes may affect gross erosion.
2nd Part – The study assess the effectiveness of incorporating information about seasonality to define homogeneous groups of sites for regional frequency analysis of hydrological extreme events. A series of Monte Carlo experiments proves for a wide study area in Northern-Central Italy that seasonality indicators have a high descriptive capability for the regionalization of floods. For the same region, the usefulness of seasonality indicators is then explored for the regionalization of rainstorms by performing a series of bootstrap resampling experiments. The study results show that the seasonality of extreme rainstorms is not particularly useful for the delineation of homogeneous rainfall regions.
