Methodologies for the analysis of alluvial fans

progetti-conoidi-veneto-evidenza Some areas mapped in the Piani di Assetto Idrogeologico (Watershed Management Plan) of Piave, Brenta-Bacchiglione and Livenza Rivers require specific studies aimed at assigning a degree of hazard. Among the warning areas, there are numerous alluvial fans. The Soil Conservation Division of Veneto Region, in charge of the inquiry, identified the need to find an objective method for assessing the hazard of such ...

Decision matrices for the assessment of fluvial processes in mountain streams

Matrici_decisionali_Cengles-03122014-evidenza Decision matrices may contribute to mountain watershed management by defining coherent event scenarios that take into account the type of flow processes (e.g., water floods with bedload, debris flows), their geomorphic effects, and the interactions with hydraulic control ...

Study of the riverbeds morphological evolution through the digital terrain models multi-temporal analysis

evoluzione-morfologica-2 The study of the evolution of the watercourses is traditionally based on the use of historical maps and aerial photographs for the comprehension of the planimetric changes and on the use of topographical sections in order to have also the measure of the altimetric change occurred in the considered time interval. Through this approach it is possible, for the Po basin, to have the first indications of the main watercourses evolution starting ...
