Název v původním jazyce

Measuring filtration velocities in the observation wells of dam and their time development

Popis výsledku v původním jazyce

Special methods for measuring filtration velocities can be used to monitor groundwater flow and seepage flow in dams' bodies and subsoil. In Slovakia, single-well indicator methods are most commonly used to measure water flow velocities. For monitoring vertical water flow in wells, a submerged device is used, which incorporates a dosing unit with pneumatic-hydraulic control of the injection of the indicator and two conductometric sensors positioned below and above the injection point. The indicator is often sodium chloride in powder form or an aqueous solution. The submerged device is connected to a computer converter via a multi-core cable, and then to a portable computer. On the computer screen, concentration curves can be directly monitored, and the time at which maximum concentration occurs (peak time) can be determined.
