METHODS AND TECHNIQUES FOR PREVENTION AND CONTROL OF THE WATER EUTROPHYCATION PROCESS IN HILLY LAKES

The paper treats the problem of eutrophication process for some important hilly lakes from Moldavia, Romania. Eutrophycation represents a normal process as time as its evolution is natural, and one of first six major environmental problems from the world lakes and reservoirs. This phenomenon is caused by the over limits increasing of nutrients concentrations (nitrogen, phosphorus) from lake's waters, substances involved through agricultural fields watering, fields on which were applied fertilizers. The paper contains a review of the main methods and techniques for modelling the processes regarding the evolution of lakes water quality. The research took place in the period 2016-2020 and regards main hilly lakes from Moldavia area, Romania.
