This study includes a calibrated simulation of the flow through networks (systems), which allows the elaboration of a future strategy of developing the networks (systems) of water and sewage. The need to develop hydraulic models as accurately as possible results from the fact that, by creating and calibrating the hydraulic model of a system, a variety of syst...

The paper presents a synthesis of our researches on the main physic - chemical and biological parameters of the Snagov Lake, from Ilfov County, Romania, made since 2013 until 2019. We have developed complex investigations on the most important water quality parameters of the lake, in the purpose of analyze the evolution of the water eutrophication phenomenon in time, in different sampling points, also to establish the optimal methods of control and combat of the studied pollution process. Because the eutrophicatio...
