Abstract
The aim of the research is to analyse, using the tools of representation science, the complex landscape and territorial system constituted by the irrigation canals of the Pavia plain. The study aims to perform simulations to verify the effectiveness of representative systems useful for the management of the irrigation system, promoting digital documentation strategies. In particular, through analysis procedures and data integration methodologies, it is intended to produce synthesis frameworks useful for providing a series of tools for the knowledge and valorisation of this historical architectural heritage on a territorial scale. The first part of the thesis deals with the historicaldocumentary research conducted with the aim of understanding the historicised image of the complex system of water routes. The network of canals, navigable and non-navigable, that qualifies the Pavia hinterland is connected to the Ticino and to the trade routes that vertically cross the Po Valley, explicating a phenomenon found in many contexts in northern Italy. The canals and rice fields that make up the landscape of the countryside between Pavia and Milan are the scene of many historical events, emblematic of a territorial system. The latter has undergone deep changes connected with waterways from the Romans, to the time of the Duchies, up to the Napoleonic reforms and the Unification of Italy. The analysis is developed by comparing regulations and considerations on the symbolic value of the landscape, making explicit the multiple interpretations that, over time, have described the canal system. Highlighting the values, both material and symbolic, attributed to watercourses, the research was carried out in close contact with the system of agricultural production. A narrative in images supported the description of the amphibious landscape analysed through texts and narratives. A selection of paintings, photographs and short films supports a geographical and socio-economic narrative of the changing nature of the irrigation network over time. The excursus among the graphic works emphasises the importance in our days of the contribution of the three-dimensional image for the knowledge, management, and control of the water element, leading to an in-depth examination of the possibilities and communication capabilities offered by the digital. The second part of the research offers some consideration on the engineering and architectural systems that determine the realisation of water landscapes, the lassifications that are currently employed for their management, and the related challenges. The requirements for the control and use of water heritage in history are taken as the key to understanding the changes and evolutions, both urban and environmental, of the places covered by the analysis. Based on this study, a representative synthesis of the water and hydraulic landscape is proposed. The landscape is, thus, disaggregated into simple geometric elements that are functional to a subsequent categorisation of the irrigation network and the historical artifacts that allow the infrastructure to function. Therefore, the research moved on to a comparison between the different two-dimensional and three-dimensional representative supports, evaluating the possible interpretations and discretisations of the landscape that are ssential for the description of the water and hydraulic heritage.
