An integrated information system is developed for simulating main processes of the hydrological cycle in Boeoticos Kephisos Basin. Both surface (rainfall, evapotranspiration, direct runoff) and subsurface processes (percolation, spring runoff, outflow to the sea) are modeled. The surface hydrology model is an enhanced version of the well-known model of Thornthwaite. The Hydrological Response Unit (HRU) serves as the basis for modeling. This is a hydrologically homogeneous part of the basin (in regard to inputs). Groundwater flow is Darcian and is supposed to take place between tanks that are linked to each other through conduits. Besides the two models, a third model that allocates water demand - which is supposed concentrated at some consumption points - between various water resources. The information system consists of four subsystems: (a) the subsystem for entry and storage of data, (b) the subsystem for organizing and visualising data, (c) the subsystem for simulation of hydrological processes, and (d) the parameter calibration subsystem. In an annex, extensive guidelines for the system's users are given. The models were calibrated and validated for the Boeoticos Kephisos Basin. This volume contains also extensive analyses of the hydrometeorological and hydrological information in the Boeoticos Kephisos Basin which led to maximising the quality of inputs to the system. Last, great effort was put in an exploratory analysis of various data of both Lake Yliki and its own basin which could not support any detailed model - even a semi-distributed one. Analysis led to a simple model for the lake's leakages which is significantly ameliorated in regard to older approaches. Also, comments are made on the potential of aquifers other than that of the Boeoticos Kephisos Basin. These aquifers are reserved mostly for water supply of the Athens Metropolitan Area.
