A Brief Overview: What is Hydrology?
Hydrology is the study of water. More specifically, it is the transport of water through the air, over the ground, and under the ground. Understanding hydrology will better help you understand the problems associated with the use and supply of water. Part of understanding hydrology is understanding the hydrologic cycle (Figure 1). The hydorlogic cycle is the circulation of water throughout the earth by precipitation, runoff, evaporation, infiltration, transpiration, percolation, groundwater recharge, interflow, and groundwater discharge. Water movement over and under the ground, as shown if Figure 2, helps explain the hydrologic history of RMC. (Ward 1995).
