As hydrology is mainly concerned with water close to the land surface, it focuses on those components of the hydrologic cycle that occur therenamely, precipitation, evapotranspiration, runoff, and groundwater. Hydrometeorology, for example, concentrates on water in the lower boundary layer of the atmosphere, while hydrometry involves the measurement of surface water, especially precipitation and streamflow. Researchers in the field rely increasingly on computer simulations of natural hydrologic systems and remote-sensing techniques, as, for example, the use of Earth-orbiting satellites equipped with infrared cameras to detect bodies of polluted water or to trace the flow of hot springs. Hydrologic research is important in the development, management, and control of water resources. water hydrolog
