Curriculum Vitae

Curriculum Vitae

Born in Lucca, Italy, on June 5th 1943, Professor Ezio Todini grew up in Egypt, where his family lived since 1946. After graduating in hydraulic engineering at the University of Pisa in 1969, he joined the IBM Pisa Scientific Centre in 1970.

He combined his role as a Research Scientist at the IBM Pisa Scientific Centre (1970-79) with that of Professor of Applied Hydromechanics at the University of Pisa (1973-80) and of Water Resources Planning at the University of Florence (1979-81). Since 1980, he has held the chair of Water Resources Planning and of  Hydrology at the University of Bologna where he also served as Director of the Institute for Hydraulic Construction (1985-1989). From 1993 (XIV Cycle) to 2009 (XXV Cycle) he has been the Coordinator of the PhD Programme "Physical Modelling for the Protection of Environment". From 2000 to 2008 he has also been President of the Management Board of ProGeA (Protezione e Gestione Ambientale), a Spin-off company of the University of Bologna.

 Prof. Todini is proficient in both English and French languages.  

 

Research Activity

Professor Todini's research activity, documented by more than 200 articles, has always been directed towards both the theoretical aspects and their practical application.

His background and experience includes Hydrology, Water Resources Planning, Hydraulics, Statistics, Numerical Methods and Operations Research.

Prof. Todini research interests range from the formulation and development of rainfall-runoff hydrological models, to flood routing models, to decision making under uncertainty, such as for instance when one has to decide whether or not to issue a flood alert and/or the amount of water to be released (or kept) into a reservoir under the pressure of an incoming flood wave.

His recent studies have been oriented to the water resources sector and in particular in the reduction of leakages in water distribution networks as well as in the analysis of physical, socio-economical environmental and ecological factors affecting sustainable water resources planning and management. For a number of years, Prof. Todini has also dedicated  noticeable research efforts in the development of Decision Support Systems aimed at Sustainable Water Resources Planning and Management.

His research in rainfall-runoff modelling has produced several models, the CLS (1976), the ARNO (1989) (which was also included as the soil moisture balance component of the ECHAM GCM model) and the TOPKAPI (1998) models, that have been and still are  extensively applied all over the world.

His approach to flood routing has produced models such as the PAB and the PABL, particularly suited for real-time flood forecasting and  the Muskingum-Cunge-Todini (MCT) method a version of the Muskingum-Cunge approach corrected for mass balance, which compares favorably with the results of full de Saint Venant equations based commercial packages such as Mike11, Hec and Sobek. These models are now in operation on many rivers.

Within the frame of  1D/2D flood inundation modeling, Prof. Todini developed a computer package based upon Control Volume Finite Elements, known as CVFE approach, while his current research aims at finding massively parallelizable approaches, such as the Cellular Automata approach.

His research in Kalman Filters originated an inverse modelling approach (INVE) for the semi-automatic estimation of transmissivity parameters in groundwater models. Professor Todini also developed approaches for the assessment of parameter uncertainty in Kriging and is now proposing a combined block Kriging - Bayesian technique for the optimal combination of rain-gauge, radar and satellite precipitation estimates. Moreover, in 1978 following the concept of Instrumental Variables, he developed the Mutually Interactive State and Parameter Estimation (MISP), a double Kalman Filter, one in the space of the state and one in the space of parameters, which has been extensively used in hydrology and has recently been recognised (2006) not only the most advanced and unbiased real time approach, but also the most efficient algorithm in the case of automatic voice identification.

In 1978, in the domain of water distribution systems, he invented an algorithm for the analysis of looped water distribution networks (the Global Gradient Method) that has recently been adopted by the US-EPA as the basis of their EPANET package, the most popular and widely used freeware for water distribution networks, and has been recognised as the most advanced and fast converging looped water distribution networks algorithm. In 2000 Prof. Todini also introduced the concept of resilience of a water distribution system and has shown how the resilience index can be used to improve water distribution networks design using a multi-criteria basis. Finally, in 2006 Prof. Todini obtained a US Patent (n. US 7,013,248 B1) for the extension of the Global Gradient algorithm to incorporate the direct computation of the variable speed pumps coefficient, while in 2009 Prof. Todini extended the Global Gradient to unsteady flow in water distribution networks, in the absence of strong inertial phenomena.

His work in stochastic optimisation of reservoirs has led to the clarification of  the concept of long and short horizon management and to the development of a real time management scheme, as a temporary correction of the long term rule, based on a minimisation of the expected costs and damages by making use of the forecasting uncertainty. This approach, successfully applied to the control and management of Lake Como in Italy since 1997, resulted in extremely important benefits with a noticeable reduction of Como flooding events,  a substantial increment of available water for irrigation and an increase in energy production of 3%.

Prof. Todini current research work is finalized to the clarification of  the Predictive Uncertainty in Hydrological Forecasting, which is erroneously estimated and interpreted in current practice. On this subject he has gained international reputation as one of the pioneers in the development of uncertainty post processors aimed at estimating predictive uncertainty and their application to real world real time flood forecasting systems such as the one on the Po river in Italy.

 

Editorial Activity

Prof. Todini is Associate Editor of Journal of Hydrology and of Hydrology and Earth Sciences Systems and he is writing the book “Hydrological Prediction, Uncertainty and Flood Risk”, together with a colleague, Prof. P.E. O'Connell, for the Wiley-Blackwell editing company.

 

International associations, research projects and consulting activities

Prof. Todini has been very active in international associations and organisations. He collaborated with WMO for the inter-comparison of Rainfall-Runoff Conceptual Models, prepared the statistical analysis for the Snow-melt Model Inter-comparison and participated in the Real-Time Updated Rainfall-Runoff Model Inter-comparison. He has taken an active role in the design and the setting up of HOMS (Hydrological Operational Multipurpose Sub-system), he has prepared an Italian version of the International Glossary of Hydrological Terms for UNESCO and, as a consultant, he has taken part in several missions on behalf of WMO in Central America, China and the Caribbean and FAO in Uganda and Ethiopia.

Moreover, he has completed the development of a DSS for the environmental assessment of Water Resources Planning based on the principle of Environmental Balance on behalf of the Egyptian Ministry of Public Works and the Egyptian Environmental Agency and an innovative DSS aiming at Sustainable Management of Water Resources within the frame of project WaterStrategyMan.

Prof. Todini has been very active in operational real time flood forecasting. He has developed more than 10 operational real-time flood forecasting systems in Italy, Germany and China, and recently he participated to project EFFS for the development of an European Flood Forecasting System and has been the Co-ordinator of the EU funded project MUSIC dealing with the Bayesian combination of rain-gauges, radar and satellite areal rainfall estimates and the assessment and communication of uncertainty to End-Users. Presently, Professor Todini is participating to project FLOODsite both as a participant and as a member of the Scientific and Technical Advisory Board (STAB).

Prof. Todini has been the co-ordinator for the writing of a report on “Understanding and Reducing Uncertainty in Flood Forecasting”, within the frame of the Concerted Action ACTIF; the author of “Hydrological Models for Flood Forecasting”, Chapter HSA131 of the Encyclopedia of Hydrological Sciences (J. Wiley & Sons) and is currently a member of the of WMO OPACHE group for the writing of the WMO Manual on Real Time Flood Forecasting.

Prof. Todini has been the rapporteur for Hydrology at the First Italian National Climate Conference (Florence, 1993) as well as an invited speaker on the status of Water Resources in Italy at the recent Conference on Climate Changes (Rome, 2007).

From October to December 2009, he spent three months of his sabbatical leave as an Invited Fellow of the Institute of Advanced Study of the University of Durham (UK), within the frame of which he delivered several public conferences.
