Student thesis: Master's Thesis


Queluz Canal, in the National Palace of Queluz (PNQ), corresponds to the reach within the precincts of the Palace of Jamor River, a tributary of Tejo River, in its final reach, the estuary. This Canal is a valuable monument, recognized both nationally and internationally. In particular, the sub-reach known as Azulejo Canal, whose walls are covered with azulejo tiles, depicting a sequence of river scenes and seascapes. Fed by the stream, the gates were closed in the summer, the channel filled with water, and the circulation in boats was a form of entertainment, together with the animation of exteriors. The mechanical floodgate system was dismantled in the 1990’s, but the canal remains basically in the original form, dating from the eighteenth century. This Canal has been suffering from occasional floods, some catastrophic. As a result, some studies were conducted, as those reported by Hidrotécnica Portuguesa (HP, 1995) and LNEC (Rocha e Fernandes, 2006). This work came from a request made by Parques de Sintra - Monte da Lua (PSML), the state owned company who manages PNQ. It aims to deepen the work done in the preceding Monograph (Pires, 2013), in order to: a) contribute to a better understanding of relevant hydraulic problems that occur in Queluz Canal; b) develop the studies carried out by Hidrotécnica Portuguesa (HP, 1995) and LNEC (Rocha e Fernandes, 2006), filling in existing gaps and overcoming technical errors; c) identify, diagnose and recommend sustainable management solutions to this reach. For flow analyses and sensitivity analyzes, to determine the robustness of the results, HEC-RAS was used, an internationally acclaimed numerical program developed by the US Corps of Engineers (USCE), which models the hydraulics of open-channel flow. Two simple empirical methods were used to estimate the peak flows – The Rational Method and Giandotti’s Hydrograph. Finally, a set of recommendations are drawn. Keywords:
