EDAPHI-PE. Dams and reservoirs
The versions of the EDAPHI-MHH hydrological forecasting applications had two methods for managing reservoirs in the future:
Reservoir outlet data stored in a time series file
Reservoir outflows for the next set in the model configuration that, by default, were set as constant and equal to the most recent SAIH measurement.
Reservoirs are treated in the MHH model as an element that cuts the topology of the system to which flows arrived (inflow) and from which they exit downstream (outflow). In the Hec-HMS model this is represented with a confluence (junction) to which the inlet flows arrive and a source (source) with flow data that represents the outlet of the reservoir.
The difference between past and future is in what is data: in the past all the series are data and in the future the inflow is the result of calculations from upstream, the outflow is a decision variable and the level (and volume) is a result.
Since Hec-HMS can only treat reservoirs with level-dependent characterizations, there are significant limitations to its representation in hydrological forecasting. This is why a solution is incorporated with MHED, which has its own hydrological calculation algorithms, although continue reading the characterization of the Hec-HMS models, but it incorporates the PE_XN module for reservoir management.
