Naturalistic Hydroseeding
The applications usually want to restore an adequate level of vegetation cover, to contrast effectively erosion and slope instability, however, often neglecting the naturalistic appearance. Really we should combine the technical aspect with the naturalistic, aiming to eliminate non-native species from vegetation context and to guide the choice of usable herbaceous species. The study, carried out in a dump of a southern Italian town (Termini Imerese - Sicily), provided for the reconstitution of plant cover of 7.4 hectares through hydroseeding applied directly on the soil of the final covering, with waste often exposed. The aim of this study was the use of alternative hydroseeding with the us…
Seismic tomography tests applied to a gravity dam
The control of the safety assessment of a dam is largely dependent on knowledge of the mechanical parameters of the actual construction, as well as its geological substratum. The application of geophysical methods can be used in existing dams to evaluate the materials (strength properties) and to verify if they match design expectations, as well as to contribute to the safety control. In particular seismics methods can considerably contribute to the examination indicating the less consolidated material and the degradation of mechanical parameters. For the characterization of the concrete conservation three seismic tomographies and a vertical seismic profile on the dam body were performed.Th…
Le rotofascine modulari (RFM): un esempio di economia circolare nell’Ingegneria Naturalistica
Si presenta un’idea progettuale nel campo delle opere di Ingegneria Naturalistica (IN) basata su una serie di principi quali: 1) il riutilizzo di materiali di scarto e la loro immissione nel ciclo produttivo; 2) l’uso di risorse rinnovabili; 3) l’ecosostenibilità e l’adeguatezza ambientale dell’opera IN proposta. Questi punti rappresentano proprio i canoni dell’Economia Circolare (sistema economico che può rigenerarsi da solo garantendo l’ecosostenibilità) che vengono applicati nella realizzazione di un’opera di IN. Ovviamente, non sarà sviluppato il tema economico ma quello costruttivo di un’opera di IN che si inquadra perfettamente nello spirito di questo approccio economico così attuale …
Organic waste materials for Bioengineering works
Bioengineering uses plant and biodegradable materials of natural origin, stones, steel, additives and synthetic products in various combinations and as support for the growth of plants. The lack of available resources and progressive increasing of desertification in Sicily, led to the search for alternative materials. Objective of the work is testing organic waste materials for the realization of bioengineering works in the several areas of application: terrestrial, fluvial and coastline. To this aim, is proposed the use of innovative techniques that involve the construction of low-cost brushwood, environmentally friendly materials made: the pruning of vines and the oceanic Posidonia oceani…
