Putting Hydrogeological Data “into Orbit”: the Geometry of Thermo-hydraulic Transients

This works addresses the processing of thermo-hydraulic data collected by suitable instruments at a Plant made of seepage wells and located in a residential area in Lombardy, a Region of Italy. Water from meteorological events (“rain water”) which falls on a building and on the surrounding impervious areas has to be disposed of separately from wastewater e.g., by seepage well plants. The latter need proper management and maintenance plans. Herewith, a research and development Project is outlined, which was started in 2017 with the aim of monitoring and characterising the Plant. The sequence of sub-Projects has included the collection of thermo-hydraulic data. Methods from the qualitative theory of dynamical, non-autonomous systems have made the processing of such data possible and triggered Plant characterisation. A product from the latter activity consists of a mathematical model of thermo-hydraulic processes in the Plant and of a method to estimate the parameters of such model, presented herewith for the first time.
