WebIt is defined as the time needed for water to flow from the most remote point in a watershed to the watershed outlet. [1] It is a function of the topography, geology, and land use within the watershed. A number of methods can be used to calculate time of concentration, including the Kirpich (1940) [2] and NRCS (1997) [3] methods. WebDefinition of Hydrological Cycle. It refers to the biogeochemical cycle that allows the constant movement of water over four spheres (atmosphere, lithosphere, hydrosphere and biosphere). Water can flow cyclically on, over and beneath the earth’s surface through the water cycle. It is a continuous pathway.
