Il Fiore delle passioni. Animo e Virtù nel sistema dei saperi tra Cinque e Seicento (parte prima: "Libertà dolce alla verità impetra". La fortuna del pensiero telesiano nel dialogo con i letterati e i filosofi dello Studio patavino e degli ambienti settentrionali, pp. 1-73)
No full textIl saggio si divide in due sezioni: l'una rivolta all'analisi del dialogo intercorso fra Telesio e gli aristotelici padovani, perlustrato lungo l'iter delle tre redazione del "De rerum natura"; l'altra, alla fortuna del pensiero telesiano negli ambienti settentrionali e presso le Accademie venete ed estensi. Si è cercato di illustrare il nodo delle questioni discusse intorno al problema dell'anima, riguardo alla intellezione dei processi pertinenti la teoria della conoscenza e lo sviluppo di un concetto di immaginazione creativa. Si è, altresì, indagata la presenza di concetti telesiani in quel vasto crogiuolo sincrestico che fu rappresentato dalla letteratura cortigiana e dall'ampia tradizione della trattatistica "de amore". Il saggio ha preso in considerazione il dibattito intercorso fra Telesio e Francesco Patrizi, e il dialogo che si instaurò fra il filosofo Cosentino e Vincenzo Maggi, Girolamo Fracastoro e Torquato Tasso
Channel adjustments and implications for river management and restoration
No full textMost Italian rivers have experienced widespread channel adjustments over the last 100 years, mainly in response to a range of human activities. The aim of this paper is to show how
knowledge of channel adjustment and reconstruction of volutionary trajectory are or can be used in river management and restoration. The first part of the paper deals with channel
adjustments and summarizes the results of recent studies carried out on twelve rivers in northern and central Italy. The second part illustrates three examples of application.
The selected rivers have undergone almost the same processes in terms of temporal trends. Initially, river channels underwent a long phase of narrowing (up to 80 %) and incision (up to
8-10 m), which started at the end of the 19th century and was very intense from the 1950s to the 1980s. Then, over the last 15-20 years, channel widening and sedimentation, or bed-level
stabilization, have become the dominant processes in most of the rivers, though channel narrowing is still ongoing in some reaches. Channel adjustments were mainly driven by 2 human actions, but the role of large floods was also notable in some cases. Different human interventions have been identified as the causes of channel adjustments (sediment mining, channelization, dams, reforestation and torrent control works). Such interventions have
caused a dramatic alteration of the sediment regime, whereas effects on channel-forming discharges have seldom been observed. The first example of application concerns a new methodology designed for assessing the hydromorphological condition of Italian rivers and for monitoring their condition through time. This methodology is required in the context of the Water Framework Directive (2000/60/EC) which aims to assess the ecological status of rivers not only using biological
and chemical elements, but also hydromorphological elements. The second example illustrates the potential of channel recovery in five gravel-bed rivers of north-eastern Italy. After defining four categories of channel taking into account recent evolution, it was analysed how different sediment management strategies could affect future channel dynamics. We concluded that even though both reach and basin-scale interventions may be carried out, it is
likely that channels will not recover to the morphology they exhibited in the first half of the 20th century, since sediment yield and connectivity will remain less than during the 19th century and the first half of the 20th century. The last example deals with solutions for promoting future sustainable management of sediment and channel processes in the Magra River catchment. Knowledge of channel evolution and its causes was used as a basis for defining channel and sediment management strategies, coupled with quantification of bedload transport and bed sediment budget, and the identification of areas most suitable for potential
sediment recharge
Coupled simulations of fluvial erosion and mass wasting for cohesive river banks
No full textThe erosion of sediment from riverbanks affects a range of physical and ecological issues.
Bank retreat often involves combinations of fluvial erosion and mass-wasting, and in recent
years bank retreat models have been developed that combine hydraulic erosion and limit
equilibrium stability models. In related work, finite element seepage analyses have also been
used to account for the influence of pore-water pressure in controlling the onset of masswasting.
This paper builds on these previous studies by developing a simulation modeling
approach in which the hydraulic erosion, finite element seepage and limit equilibrium
stability models are, for the first time, fully coupled. Application of the model is
demonstrated by undertaking simulations of a single flow event at a single study site for
scenarios where (i) there is no fluvial erosion and the bank geometry profile remains constant
throughout, (ii) there is no fluvial erosion but the bank profile is deformed by simulated
mass-wasting, and (iii) the bank profile is allowed to freely deform in response to both
simulated fluvial erosion and mass-wasting. The results are limited in scope to the specific
conditions encountered at the study site, but they nevertheless demonstrate the significant
role that fluvial erosion plays in steepening the bank profile, or creating overhangs, thereby
triggering mass-wasting. However, feedbacks between the various processes also lead to
unexpected outcomes. Specifically, fluvial erosion also affects bank stability indirectly, as
deformation of the bank profile alters the hydraulic gradients driving infiltration into the
bank, thereby modulating the evolution of the pore-water pressure field. Consequently, the
frequency, magnitude and mode of bank erosion events in the fully coupled scenario differ
from the two scenarios in which not all the relevant bank process interactions are included
