ANALISI DI RISCHIO

sorgente

percorso

recettori

Ogni analisi del rischio dovrebbe offrire i dati e le informazioni per definire la catena:

sorgente -> percorso -> recettore



Gli obiettivi sono:

• determinare la natura e l’estensione della contaminazione (pericolosità)

• caratterizzare il mezzo fisico (percorsi)

• comprendere la natura di recettori potenziali e relativi rischi

• fornire informazioni per le decisioni di gestione e bonifica

PER ESEMPIO: CARATTERIZZAZIONE DEI SITI CONTAMINATI



Il prodotto finale: UN MODELLO CONCETTUALE

CARATTERIZZAZIONE DEL SITO

PROGETTAZIONE DELLA CARATTERIZZAZIONE



p.es. la migrazione di contaminanti è governata da molti meccanismi fisici, chimici e biologici

il più importante:

• trasporto con l’acqua nel saturo e nel non saturo

ma altrettanto cruciali:

• flusso come fase separata (DNAPL o LNAPL)

• assorbimento/desorbimento dalla matrice solida

• biodegradazione

[C.W.Fetter, 1999]

Il saturo



Le variazioni spaziali della velocità di flusso e quindi la macro-dispersività dipendono dalla variabilità nello spazio della conducibilità idraulica K

The Borden aquifer experiment [Sudicky et al., 1986]

Il saturo



Dall’analisi dei momenti spaziali dei plume di soluti è possibile ricavare la

macro-dispersività, e da questa le statistiche del campo di K

Borden experiment: plume di bromuro

[Barry and Sposito, 1988]

(Vista dall’alto)

Il saturo



Per effettuare un’analisi attendibile dei momenti spaziali dei plume di soluti è necessario un campionamento molto fitto nel tempo e nello spazio.

Tecnica non applicabile nella pratica comune

Enorme numero di punti di campionamento!

Misure geofisiche

(e altre misure tradizionali)

Modello fisico-

matematico (p.es.

idrologico)

Parametri fisici (p.es.

conduttività idraulica) dinamica

(fluidi, temperatura)

struttura (geometria, geologia)

Integrare misure e modelli fisico-matematici che spieghino

l’evoluzione spazio-temporale delle variabili di stato quali il

contenuto idrico, la concentrazione di soluti e la temperatura che a loro

volta influenzano le variazioni spazio-temporali dei dati geofisici.

INTEGRAZIONE CON I MODELLI PREDITTIVI

STIMARE TUTTE QUESTE

COMPONENTI



In passato:

Ricerca di relazioni dirette tra

grandezze geofisiche (p.es. velocità

sismica, resistività elettrica) e

grandezze idrologiche (p.es.

conduttività idraulica)

Obiettivo: caratterizzare la struttura e l’idrologia dei versanti

di un piccolo bacino montano affetto da frane per scivolamento

e soprattutto rischio alluvione

Sito sperimentale di Montemezzo

bacino del torrente S. Vincenzo (Cassiani et al., 2009, Near Surface Geophysics

Strobbia and Cassiani, 2007, Geophysics)

quota: 1150 m s.l.m.

pendenza: 30-40 gradi

copertura di suolo: spessore di 1-2 m, morena

sabbioso-ghiaiosa; conduttività idraulica medio

bassa (10-6 m/s)

basamento: paragneiss con foliazione sub-verticale,

friable.

vegetazione: erba, con bosco circostante di faggi e

betulle

Grave rischio di inondazione

Stazione di monitoraggio idrologico

A partire dal 2003 è stata condotta una campagna di monitoraggio di lungo termine, con misure di:

• precipitazione,

• ruscellamento superficiale,

• temperatura del suolo,

• contenuto idrico del suolo.

Il 29 ottobre 2007, sono stati

applicati 9330 litri di pioggia

artificiale su un’area di 2 m x 2

m per 18 ore (equivalenti a una

pioggia di 2500 mm).

L’infiltrazione è stata stimata

sottraendo il ruscellamento

misurato.

Date le condizioni meteo ed il

ridotto periodo di irrigazione

l’evapo-transpirazione è stata

trascurata.

Il rischio idrologico-ambientale va affrontato anche con una migliore comprensione dei processi fisici, chimici e biologici, e delle caratteristiche dei sistemi.

La geofisica può dare un sostanziale aiuto in questo senso, specie perchè è fortemente affetta dalle caratteristiche statiche e dinamiche del suolo e sottosuolo.

Questo fatto, se adeguatamente riconosciuto, offre un enorme contenuto di informazione sui processi e sulle strutture.

L’informazione ottenibile si massimizza con misure ripetute nel tempo e integrazione con modelli predittivi dei fenomeni stessi.
