Abstract: The paper contains the overview of so-called vortex valve, used as outlet device on retention reservoirs for retention of rainstorms and later slow outflow into drainage etc. Simple one-dimensional equations are well known, but for complex three-dimensional flow fields inside the valve the method of flow numerical simulation is used. Particular paragraphs contain the theory of flow fields inside, explanation of branched flow characteristic, separated by transitional area, basics of designing and influence of both inlet/outlet opening sizes on the form of characteristic, valve adaptation for high flows at low water levels etc. Results are used for designing of new model series of valves for various water flows and levels.
