Born in 1986, in Cali, Colombia, Juan Carlos is a Civil Engineer (Pontificia Universidad Javeriana Cali, Colombia) with MSc in Water Science and Engineering, specialisation in Hydroinformatics (IHE Delft, Netherlands). During his professional life, he has worked in areas of hydrological modelling for operational flow forecasting systems, water loss control in urban distribution systems and slope stability analysis and design. His links with academia are strong, devoting most of his time in research and applied research consultancy.
His research interests are diverse, among which are:
- Hydrological modelling
- Data-driven modelling
- Mathematical and statistical modelling
- Hydraulic and hydrological monitoring
- Data assimilation
- Water loss control in urban distribution systems
Additionally to this, it is of great interest the development of open source modelling tools, such as the HIPy initiative.

Current theories and methods for designing monitoring networks aim to place traditional, fixed sensors to accurately infer spatial and temporal state of water systems and forecasts. Citizen Observatory of Water, however, needs to couple data from diverse sources forming a network of fixed and dynamic sensors providing physical and social data, identify the best spatial and temporal data needs, allowing dynamic sensors, such as those carried along by citizens, to complement the information coming from traditional fixed sensors and remote sensing tools. The main objective of this study will be to develop and test the mathematical and algorithmic framework for dynamic network optimization, able to identify the optimal sensor locations, variables to measure, time coverage, and reliability range in real-time providing the best possible information content, e.g., for a flood or water quality forecast. Additional tasks relate to the fact that physical and social sensors may be providing conflicting information, and this would need the selection of dedicated dynamic social sensors (humans activating the carried physical sensors, or sending verbal information) to be requested to visit particular locations of interest to resolve a conflict. Multi-objective optimization methods to be tested and refined will include methods developed in the area of computational intelligence (evolutionary and adaptive random search algorithms), made however more robust due to uncertain data, and more efficient due to the use of computationally intensive models. In computing, use of parallelization using clusters and cloud computing is foreseen.
On 24 September 2019, Mr Juan Carlos Chacon Hurtado successfully presented and defended his PhD thesis and was awarded with a Doctoral degree.
