The geomorphological assets are characterized by scientific, cultural, socio-economic and landscape attributes. Scientific attributes may vary (peculiar geomorphologic evolution; educational value; palaeogeomorphological environmental importance; naturalistic rarity; and ecological assessment) and each value may have a different rank (global, national, regional, locai, or none). Manual and computer techniques to elaborate thematic maps are reported as applied to different test sites in th\ue8 Alps, Apennines and Po Plain

It is based on the ranks of the numerical values obtained by the modelling. Such ranks can be displayed in the form of histograms, cumulative curves, and prediction patterns resembling maps. A number of models have been proposed and in this contribution the following will be compared in terms of their respective rankings for equal area classes: fuzzy set function, empirical likelihood ratio, linear and logistic regression, and Bayesian prediction function. The analyses performed and contrasted exemplify a generalized methodology for comparing predictions that should allow evaluating prediction patterns from any model. Unfortunately, many applications in the scientific literature use methods of characterizing prediction quality that make comparison hard or impossible. A database from a study area in the Mountain C...

Flood modelling can be used to forecast how large embanked structures affect the propagation characteristics of floodwaters during a flooding event. Change in these characteristics will alter the risk of the flood to the structure itself and to the surrounding environment. Flood modelling can thus be included in the environmental impact assessment that is usually required for these projects. Once it is clear that a new project ...

Such studies are possible using aerial photographs. The methodology applied for the nuclear power sites in Italy is presented. The task is to assess the neotectonic activity testified by the geomorphological evidences during the Quaternary. Two different cases, to explain the

The Po Plain foredeep was nourished by large amount of debris coming from exogenous processes of erosion of both mountain chains. During Pleistocene, the foredeep has assumed a W-E direction along the Appenine margin, corresponding to the Po River course, deeper eastward. At the same time, at the northern margin of the plain, isostatic processes have been responsible of relevant raising. Sediments in the area have been deposited firstly in a marine basin, then in a wide delta-lagoon region, and more recently, a continental sedimentation prevailed. The area was dominated by large alluvial fans coming from the main Alpine valleys while in the southern part of the plain, where finer sediments are widespread, intense subsidence phenomena due to compaction of the sedimentary deposits occurred. During Quaternary, fluvial transport and sedimentation was strongly influenced by climate changes and, in the cold stages, large amount of debris were produced on the mountain chains and remarkable sea-level changes caused marine ingression in the middle of the Po Plain alternating to as much relevant regressions. Through the use of GOCAD software, using SGRID frame, voxels 500x500 m were obtained interpolating between Topo and A surfaces subdivided in 90 intervals, between A and B surfaces in 84 intervals and between B and C surfaces in 74 intervals respectively. The surfaces A, B and C, (Regione Lombardia & ENI-Divisione AGIP, 2002) were dated back respectively to 450, 870 and 1240 Ky. In each voxel, gravel, sand and clay texture distribution have been interpolated using percentage of texture for each metre assumed from stratigraphic data of the wells (11,993) stored in TANGRAM database. Interpolation has been carried out using kriging methods into GOCAD environment. To each voxel, the value of texture percentage has been assigned and the distribution in space and time has been modelled. 3D analysis related to clastic deposits distribution in the whole studied area testify that: 1) gravels deposited in the piedmont area over sand and clay materials from MIS 22 (870 Ky), and prograding gradually southward, are the effects of the beginning of glacial phases; 2) sand levels interbedded with clay ones, along the south-eastern Po river axis, have a geometric sequences, along axis Z, according to temporal sequences, effects of climate changes during Pleistocene.

The application of this model has permitted an analysis of the spatial distribution of the structure (DTM and landslide bottom) and the mass transfer elements of the hydrogeological system. The field survey suggested zoning the area on the basis of the recharge, groundwater fluctuation and drainage system. For each zone, a hydraulic conductivity value to simulate the different recharge and the drainage responses has been assigned. The effect of rainfall infiltration into the ground and its effect on the groundwater table, with different intensity related to different time periods, have been simulated to reproduce the real condition of the area. The applied model can simula...

This package can be used to store, display, and process all data related to water wells, including administrative information, well characteristics, stratigraphic logs, water levels, pumping rates, and other hydrogeological information. Currently, the database contains more than 39.200 wells located in the Italian region of Lombardy (90%), Piedmont (9%) and Valle d’Aosta (1%). TANGRAM© has been created both as a tool for researches and for public administration’s administrators who have projects in common with DISAT-UNIMIB. Indeed, transferring wells data from paper into TANGRAM© offers both an easier and more robust way to correlate hydrogeological data and a more organized management of the administrative information...
