Hydrometeorological data processing

The hydrometeorological data analysis for the estimation of the areal rainfall, the evaporation and the runoff at specific discharge measurement stations is described. Also, the reservoir water balances are presented, which were established for the estimation of the inflows or leakage losses of the system's reservoirs (Evinos, Mornos, Yliki, Marathonas). Specifically, we present the processing of the monthly rainfall data, the estimation of monthly evaporation from the reservoirs, the calculation of the discharge at the three main watersheds (Evinos, Mornos, Boeticos Kefissos) and the setting up of the monthly water balance components. All raw and processed hydrologic time series are stored in the central database.
