HYDROLOGY - BASIC CONCEPTS

The importance of hydrologic cycle in hydrology is such that Hydrology is also briefly defined as the science of hydrologic cycle. Figure 1.1 shows a schematic flow chart of the hydrologic cycle. Though the actual hydrologic cycle is quite complex, this figure just broadly depicts the sequence of major events of the cycle.
