Researchers monitor rivers and springs to predict what part of the water resources to use for irrigation for industry, drinking needs to maintain ecosystems. The main task of the scientific staff is to monitor and control the water quantities coming out freely from natural caverns, rock crevices, free-flowing rivers and springs. The measurements of kinematic quantities, can serve not only for the quantitative evaluation of the runoff, but also for the verification of the theoretically derived hydraulic dependencies in the different forms of water movement. When determining the water quantities, observations of the runoff are carried out, as well as the measured parameters can serve to play an important role in the construction of water management facilities
