Hydrology is the study of the movement, distribution, and quality of water throughout Earth, and thus addresses both the hydrologic cycle and water resources. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage basin management and water chemistry, where water plays the central role.
Hydrological models are conceptual and simplified representations of a part of the hydrologic cycle. They are mostly used for forecasting and understanding of hydrological processes: given precipitation data, models can estimate flow at the closing section of a river basin.
In cooperation with University of Bologna and under the guidance of Prof. Ezio Todini, PROGEA has developed two hydrological models and it distributes them since the '90:
ARNO it is a semi-distributed conceptual model that belongs to the family of variable contributing area models.
TOPKAPI it is a fully-distributed and physically based model that can be used at spatial and temporal scales of primary interest for operative hydrology.
Implementation and calibration of the model
PROGEA simulates with TOPKAPI model the hydrologic behavior of small, medium and large catchments, using few minutes' time steps for flash-floods forecasting in steep mountain basins, hourly time steps for flood forecasting in medium size catchments, daily time steps for the study of water resources at catchment scale. The main fields of application concern:
Activities performed during the implementation of TOPKAPI model include:
In order to better understand quality of results produced by TOPKAPI model, the activities of implementation and model calibration are followed by training to end user's technicians to illustrate model characteristics and particularities of model implementation.
