A. Tegos, Combined simultation of hydrological-hydrogeological processes and operation of Western Thessaly hydrosystem, Diploma thesis, 132 pages, Department of Water Resources, Hydraulic and Maritime Engineering – National Technical University of Athens, Athens, September 2005.
The scope of the study is the integrated simulation of the hydrological cycle in the Western Thessaly region, through the HYDROGEIOS model. First, the raw data for the hydrosystem was collected (data from hydrometric and pluviometric stations, groundwater data, agricultural data). Next, we proceeded to the schematisation of the physical and artificial system. For the adaptation of the model, i.e. the estimation of its parameters, an objective function was formulated, based on field measurements for surface and groundwater resources. The function comprises 16 components. Through optimisation, we attemted to find the minimum distance between the observed and simulated time series. The study refers to the period 1972-73 to 1992-93. The first decade refers to the calibration period, whereas the second one is the validation period, in which the forecasting capacity of the model was tested. Taking into account thecomplexity of the problem, the adaptation of the model was satisfactory, while useful conclusions were derived, which may be used for management purposes.
