Basic engineering and economic characteristics regarding water resources management of Thessaly

Since the beginning of the 20th century, the development of Thessaly passed through several stages characterised by the construction of particular works, which were judged as beneficial for agricultural development. In the near future, the Acheloos diversion project is expected to create new conditions for the Thessaly and the national economy. However, a complete study for the optimisation of the economical parameters, including energy, agricultural, and environmental aspects, has not been made until now. This study summarises the basic technical, hydrological, hydrogeological, and economical characteristics of the necessary works for the development of the Thessaly's water resources including the Acheloos diversion project. From the values provided, a picture of the parameters that should enter into an investigation of the optimal water resources management schemes is obtained, and a policy of the planning and design of the major works is outlined.
