Fluvial dynamics in the Castel di Sangro plain: morphological changes and human impact from 1875 to 1992

Abstract In recent years, morphology and hydrogeology of the Castel di Sangro plain have undergone significant man-made changes. The plain is located in a very complex geological area where the Latium-Abruzzi carbonate platform, the Morrone-Rotella-Pizzone carbonate platform and the Molise nappe meet. Hydrology, hydrogeology, morphology and neotectonics of the area are conditioned by interlocking and overlapping of such palaeogeographic units. Some of them can be clearly recognised in the upper and middle Sangro area. After outlining the geological, structural and geomorphological features of the area, the authors discuss the morphological changes which occurred in the Sangro River pattern and its alluvial plain from 1875 to 1992 as a result of construction of major hydraulic structures (dams, river bed cementation, urbanisation of flood plain and spring areas, wells). Elements inferred from comparison of maps and aerial photographs were also considered. The study provides a concise description of objective observations on both natural and man-induced fluvial processes and groundwater flows.

Extreme rainfall in coastal metropolitan areas of Central Italy: Rome and Pescara case studies

This study analyzes the historical series of precipitation fallen along Latian coast and Abruzzo coast, and extreme rainfall in the context of climate change. Daily precipitation data cover the years ranging from 1922 to 2009 for one meteorological station, and from 1951 to 2010 for five stations. We focus on the extreme values following two approaches: the first one is based on the maximum annual daily rainfall series (1-day, 2day and 3-day) for which suitable probability distributions are fitted. The second one is based on the series of peaks over annual thresholds (POT) for which the best fitting distribution is identified. The aim of this analysis is to estimate rainfall return levels for various return periods. This is particularly helpful to the Local Administration for the urban planning and for alerting residents in metropolitan areas.
