And Behavior

In this paper, we studied the geo-hydrological structure and behavior of a reference catchment, located in the Cilento UNESCO Global Geopark, southern Italy, representative of the hilly, terrigenous and forested headwaters of the Mediterranean eco-region. Based on detailed hydrogeological and hydro-geomorphological surveys and geomorphometric analysis, starting in 2012, a hydro-chemical monitoring activity at the catchment and sub-catchment scale started, and a hydro-chemical dataset was progressively recorded at daily and sub-hourly time steps. Based on this dataset, the authors performed an original procedure to identify different runoff components, derived by applying cascade mass balance filtering. The integration of hydrological and geomorphological approaches allowed us to obtain an interesting conceptualization of the storm flow generation using hydro-chemical signatures related to different runoff components produced during the increasing–decreasing cycle of the flood event magnitude. The hydro-system activated progressively different runoff sources (i.e., groundwater, riparian corridor, hillslope and hollow) and involved various mechanisms (i.e., groundwater ridging, saturation-excess, infiltration-excess and soil pipe exfiltration). The geo-hydrological conceptualization was validated using a hysteresis Q-EC loop analysis performed on selected events that showed how hysteretic indices could be used to characterize the events in respect to their origins, mechanisms and pathways in similar catchments.

Abstract The Eurasian otter (Lutra lutra) is among the most endangered mammals in Italy, its population being isolated and genetically distinct from other European populations. Yet, its ecology and behavior are largely unknown in Italy, preventing its much-needed effective conservation. We radio-tracked one male and one female otter daily in Southern Italy, for 1 year and 8 months, respectively. The male and female used nearly 30 and 20 km of river, respectively. The extension of the ranges varied among seasons. The male was more conservative in its spatial utilization, being mostly located around a trout farm. These first direct data on space use by wild Italian otters provided preliminary information potentially useful for a sound management of this endangered population.

Flow Generation

Abstract. A Bayesian approach is described for dealing with the problem of infilling and generating stochastic flow sequences using rainfall data to guide the flow generation process, and including bounded (censored) observed flow and rainfall data to provide additional information. Solutions are obtained using a Gibbs sampling procedure. Particular problems discussed include developing new procedures for fitting transformations when bounded values are available, coping with additional information in the form of values, or bounds, for totals of flows across several sites, and developing relationships between annual flow and rainfall data. Examples are shown of both infilled values of unknown past river flows, with assessment of uncertainty, and realisations of flows representative of what might occur in the future. Several procedures for validating the model output are described and the central estimates of flows, taken as a surrogate for historical observed flows, are compared with long term regional flow and rainfall data.

And Behavior

The perception of risk is influenced by how the signals about impacts of events are collected, selected, and interpreted. Empirical data suggest that significant differences in the perception of risk occur within the non-expert population itself, as well as between experts and non-expert population. The paper seeks to examine the risk perception of citizens living in an area subject to high hydro-geological risk of Calabria (Southern Italy), and understanding if local policy makers are aware of how local residents perceive risk. Quantitative and qualitative methods were employed to analyze the perception of experts, stakeholders and citizens on the following research topics: (i) perception of geohydrological risk, involvement in past events and behavior exhibited; (ii) information, communication, preparedness, and feeling of safety and trust. The results of the survey showed the communication gap between experts and people, evidencing the need for local authorities and experts to disseminate the culture of awareness on the risk and to increase the safety level of the citizens by means of participated actions aimed at reducing urban disaster risk.
