Research Interests

The ultimate aspiration of the research topics of Christian Massari is the mitigation of the contemporary water related problems which seriously affect natural water resources and infrastructures (such as floods, water shortage and water wastage). His research is aimed at solving water problems in poor areas of the world where financial resources and data are limited and the development of robust hydraulic and hydrologic modeling is often a hard challenge. The philosophy of his work is based on data fusion, assimilation and integration techniques for including “external” information for reducing model uncertainties and improving predictions in order to take prompt and effective actions for solving water related problems.

Christian Massari works on different fields of hydrology and hydraulics where he uses data fusion and assimilation techniques for improving hydrologic and hydraulic applications.

1)      In the field of hydrology, the research is focused on data assimilation of different kind of remote sensing observations for improving inputs (e.g., rainfall), states (e.g., soil moisture) and outputs (e.g., discharges). The main objective is the reduction of flood hazard in poorly gauged and inaccessible areas. Remote sensing observations are primarily used for (1) compensating the lack of data in inaccessible and poorly instrumented areas, (2) improving the spatial calibration of the model parameters, (2) real-time updating of models states and parameters to get improved forecasts, (3) enhancing input observations (i.e., rainfall) by using remotely sensed datasets. The main target of his research is the efficient integration and use of satellite measurements in hydrological models in order to provide alternative and compensatory data sources for the improvement of hydrological predictions. In this field, Christian Massari has proposed a new modelling technique, which directly uses globally available (from satellite and land surface models) soil moisture observations for obtaining a reliable “external” estimation of the rainfall-runoff partitioning which is used to predict flood hydrographs. Currently he is working on the development of a new globally available precipitation dataset obtained from satellite soil moisture observations and in integrating this dataset with state-of-the-art satellite rainfall products for improving their ability to reproduce ground observed rainfall.

The final objective of his research is the development of a modelling and assimilation chain, which allows to properly and efficiently integrate different kind of remote sensing observations (e.g. soil moisture, data altimetry, precipitation from space) for flood and drought prevention in poorly gauged and remote areas of the world. The latter is also significant for having a better view of the hydrological cycle at a coarser scale (the scale of the satellite applications).

2)      In the field of hydraulics, the research has focused on the use of data fusion and data integration techniques for detection of the anomalies afflicting deteriorated pipe systems such as leaks, illegal branches and partial blockages in pipelines. Such anomalies impede the sustainable and correct use of the urban and agriculture water resources limiting the correct, safety and the sustainable development of the populations. In this filed, Christian Massari has proposed and developed a new technique for blockage detection which is able to simultaneously use innovative and state-of-the-art measurements of the pipe inner diameter and transient pressure measurements for exploring and diagnose buried pipe networks. The technique has the advantage to be very cheap and fast and to not requiring water service interruptions allowing to explore many kilometers of a buried pipe network with few short (few seconds) pressure measurements from the accessible points of the network (i.e. its boundary).

Other research interests concern:

1)      use of wavelet analysis for filtering hydrologic and hydraulic time series to get improved quality of the used data;

2)      use of wavelet analysis for improving anomaly localization in pipelines;

3)      study of the effect of the pipe viscoelasticity (e.g. polyethylene) on leaks, valves and blockage in water pipelines.

The research activity has included experimental, analytical and numerical aspects of the abovementioned topics. He has published a total of 52 papers with 17 international journal articles, 6 refereed national journal articles and 19 papers in proceedings of national and international conferences.
