GGR206H1 Chapter Notes - Chapter 1,2: Groundwater Recharge, Water Cycle, Water Vapor
Document Summary
Hydrology: science dealing with waters of earth, their occurrence, distribution, and circulation, chemical and physical properties, interaction with environment. Is also only chemical compound occurring in normal conditions as solid, liquid, or gas. Water plays a fundamental role in the distribution of chemicals. Water vapor is principal greenhouse gas in atmosphere. Only 0. 3% of water is in mobile freshwater. Water that actively contributes to rainfall, evaporation, streamflow. Hydrological cycle: interdependent movement and continuous movement of all phases of water (solid, liquid, gaseous) Hydrological cycle ensures process of transfer between land, ocean, and atmosphere, through streamflow, groundwater flow, evaporation, and precipitation. Some is intercepted by vegetation cover or buildings and evaporated back into atmosphere. Be stored as ice/snow before melting or sublimation. Flow into streams/lakes and then evaporate, seep into groundwater, or flow into oceans. Infiltrate ground surface to join existing soil water. Removed by evaporation, throughflow to stream channels, percolation to groundwater.
