EDAPHI-MH. Operational hydrological models based on Hec software

Hydrological forecasting requires the use of models, to predict levels and flows, in a very special way, such as real-time operational

The ability to apply filters to the data is required, the ability to work with missing data, the ability to quickly modify parameters or have automatic calibration utilities.

EDAPHI has been built on the consideration of these and other requirements, and has served to generate the MH simulation and forecast models:

  • MHH, which is supported by the HEC-HMS and HEC-DSSVue applications (, and was the first EDAPHI hydrological model, or

  • MHED, whose calculation algorithms are incorporated in the Python code, although it takes the description of the hydrological system from the HEC-HMS files.

EDAPHI-MHED includes reservoir lamination algorithms integrating the PE-XN module

A previous module, MHH-H (Hypermodels based on MHH models), is maintained, although it is currently deprecated in operational cases, since general capabilities were incorporated into EDAPHI that may present advantages when organizing a complex application case. It should be said that it is now possible to implement a hypermodel without the need to use a specific module. The solution is now based on the organization of modules and application cases and the use of general utilities.

EDAPHI-MH used in operational mode - real time

The EDAPHI-MH modules perform hydrological calculations in real time with results of levels and flows, allowing multiple scenarios to be contemplated and managed, which facilitates a non-deterministic approach, such as one based on inputs related to probabilities of occurrence.

EDAPHI-MH used in study mode

In addition to being prepared for real-time hydrological forecasting (operational mode), the EDAPHI-MH modules can be used in study mode, simulating scenarios without consideration of operational phases or distinction of future or past time.
