| Title | STUDIO DEI FLUSSI IDRICI DAL SUOLO ALLA FALDA UTILIZZANDO UN MODELLO MATEMATICO CALIBRATO CON DATI SPERIMENTALI |
| Abstract | This paper reports the results of an experimentation, carried out with the purpose of defining the necessary parameters to set up and run a model to simulate the water flow in the unsatured zone. Incoming and outgoing flows were misured, almost weekly, in six month, in three lysimeters filled with soil, cropped with loietto and irrigated with drinkable water. Using this measured data a daily water balance was performed and, later, verified using the soil moisture values measured, monthly, along the vertical profile of each lysimeter. The water balance validation produced a time series of daily incoming and outgoing flows used as boundary conditions for the model simulations. Measured values of the model content, along the vertical profile of each lysimeter, were also used for the model calibration. SATINSAT, a computer program for simulating saturated/unsaturated two-dimensional flow and transport in ground-water system, was used. Results in form of daily water balances, water content vs hydraulic conductivity, matric potential and soil depth are reported, which confirmed that SATINSAT well represents the hydrodynamics of the considered system. |

La sperimentazione, oggetto del presente lavoro, e stata finalizzata alla calibrazione di un modello matematico in grado di simulare il flusso idrico negli strati non saturi del suolo. Sono stati utilizzati dati sperimentali relativi a tre lisimetri riempiti di suolo, sottoposto ad irrigazione con acqua di rete, su cui e stata praticata la semina di loietto. Durante la fase sperimentale, durata circa sei mesi, sono stati registrati i flussi entranti ed uscenti da ciascun lisimetro. La validazione del bilancio idrologico ha consentito di poter disporre di una serie storica sufficientemente lunga da utilizzare come input del modello. E stato utilizzato il codice di calcolo SATINSAT che descrive l idronamica sotterranea per suolo saturo e non saturo. Le misure puntuali del contenuto di acqua misurate lungo la verticale hanno consentito di tarare il modello. 1 Articolo pubblicato articolo_def.pdf Articolo in rivista Associazione idrotecnica italiana 1125 1255 L Acqua Roma, 1996 L Acqua Roma, 1996 Acqua Roma, 1996 L Acqua.
