In the present thesis, the Misa River watershed is analysed, passing through the precipitation, temperature and discharge of the watershed. The analysis was done using the following stations: Arcevia, Bettolelle, Barbara, Colle and Corinaldo. In a first time it was calculated the daily value of precipitation, temperature and discharge for each station, and later the monthly value for all the parameters that characterize the watershed. Once it was calculated the average value of each parameter, passing through the Inverse Distance Weighted Method, the data were used for the application of a hydrological model aimed at finding the river discharge. Simulations have also been carried out using the HEC-RAS software, that gives information about the water level, that is calculated passing through the discharge. The simulation with HEC-RAS was done for all the sections of the river but for comparison purposes, only the sections of Bettolelle and Ponte Garibaldi have been analyzed. Close to the Ponte Garibaldi station there is the horizontally acoustic doppler current profile (H-ADCP), that is a gauge that gives as output data only relatively high values of water level. The data of this river gauge are collected and used, mainly the data of November, to find a rating curve for the Ponte Garibaldi station. With the aim to extract the rating curve, the H-ADCP data and the results obtained from the HEC-RAS simulations have been compared.

Abstract

In the present thesis, the Misa River watershed is analysed, passing through the precipitation, temperature and discharge of the watershed. The analysis was done using the following stations: Arcevia, Bettolelle, Barbara, Colle and Corinaldo. In a first time it was calculated the daily value of precipitation, temperature and discharge for each station, and later the monthly value for all the parameters that characterize the watershed. Once it was calculated the average value of each parameter, passing through the Inverse Distance Weighted Method, the data were used for the application of a hydrological model aimed at finding the river discharge. Simulations have also been carried out using the HEC-RAS software, that gives information about the water level, that is calculated passing through the discharge. The simulation with HEC-RAS was done for all the sections of the river but for comparison purposes, only the sections of Bettolelle and Ponte Garibaldi have been analyzed. Close to the Ponte Garibaldi station there is the horizontally acoustic doppler current profile (H-ADCP), that is a gauge that gives as output data only relatively high values of water level. The data of this river gauge are collected and used, mainly the data of November, to find a rating curve for the Ponte Garibaldi station. With the aim to extract the rating curve, the H-ADCP data and the results obtained from the HEC-RAS simulations have been compared.
