Document Summary
Chapter 2- quantity and quality : introduction to water resource. Introduction of basics: hydrology and water quality. Scientific disciplines: fluvial geomorphology, aquatic ecology. Hydrologic cycle: the movement of water in the environment: cycle: reflects the fact that the amount of water on. Earth is fixed: water is continually moving from ocean atmosphere. Precipitation: ex. rain, sleet, hail, snow, occurs as a result of adiabatic cooling. A process which air mass rises, expands and cools. Cold air holds less water than warm air. Cooled air can become supersaturated with water vapor leads to form clouds and drops of condensed water fall as rain: precipitation with different characteristics: Moisture-laden (mountains) air is forced upward leading to adiabatic cooling & precipitation on the windward side of the mountains. Less rain since descending air mass can hold more moisture. Precipitation often forms along the boundaries of air masses of different temperatures & densities. Cold frontal moving under warmer air = short, high-intensity rainfall.
