ABSTRACT

For water management in time and space, the hydrologic cycle is a model of holistic nature. There are different definitions of the hydrological cycle, but it is generally defined as a conceptual model describing the storage and circulation of water between the biosphere, atmosphere, lithosphere, and hydrosphere (Karamouz and Araghinejad, 2005). Water can also be arrested in nature in the atmosphere, ice and snow packs, streams, rivers, lakes, groundwater aquifers, and oceans.Water cycle components are affected by processes such as temperature and pressure variation and condensation. The means of water movement is through precipitation, snowmelt, evapotranspiration, percolation, infiltration, and runoff.
