HYDRAULIC CONSTRUCTIONS

  • Optimal selection of the rehabilitation interventions of water networks, with particular reference to conditions of scarcity and uncertainty of information. Asset management models of networks and plants in the framework of the integrated water service and decision support systems (Decision Support Systems, DSS).
  • Anti-seismic upgrading of water infrastructure in the framework of routine maintenance of networks and plants, aimed at the minimization of seismic risk.
  • Concise indicators of hydraulic reliability and design robustness of distribution networks.
  • Assessment, analysis and hydraulic modeling of water losses in distribution networks.
  • Simulation of water quality in urban water distribution networks.
  • Benchmarking of the management of urban water distribution and drainage networks and wastewater treatment plants.
  • Optimal management of large hydraulic systems through specific modeling software.
  • Management of urban water networks under conditions of scarcity of resources.
  • Selection of the optimal return period of the hydrological input for the design of urban drainage networks, based on the minimization of the total cost (construction, maintenance and flooding damages) during the life cycle of infrastructure.
  • Analysis of consumptions and limitations of water losses in water supply systems with an intermittent functioning.
  • Study of energetic impact due to water scarcity.
  • Uncertainty analysis of flood damages assessment in urban areas.

 HYDROLOGY AND HYDROGEOLOGICAL RISK

  • Time series analysis of climate variables.

  • Coupling between spatially-distributed, physically-based hydrological models and soil erosion models.
  • Hydrological applications of radar meteorology in urban systems.
  • Remote sensing of precipitation from satellite platforms.

 WATER RESOURCES MANAGEMENT

  • Multi-regressive models for the prediction of water availability for the optimal management of reservoirs at multi-annual scale, based on drought risk mitigation and minimization of total costs.
  • Use of reservoirs for the temporary accumulation of water therein pumped using the peaks of energy production from intermittent renewable sources (particularly wind) exceeding the instantaneous electricity demand.

 FULL FIELD ACTIVITIES

 REMOTE SENSING AND GIS

  • Modeling and monitoring of hydrologic variables by means of remote sensing data, with a special attention to the spatial and temporal evolution of evapotranspiration and surface soil moisture.
  • Precision irrigation and precision farming applications by means of remote sensing data and in situ weather data acquisition.
