Rivers and the narrower streams that feed into the rivers are continuously moving bodies of water that carry water from the source or headwater to the mouth at a lake or ocean. If the temperature is hotter then the amount of water in the river will decrease due to the evaporation and transpiration that is happening; If the cli Keeping streams and rivers clean helps keep all the water downstream clean, too. What is the discharge of this stream? As water flows downstream, streams and rivers most often gain water volume, so at base flow (i.e., no storm input), smaller headwater streams have very low discharge, while larger rivers have much higher discharge.

Bacteria are also a big water quality problem. They contain dangerous chemicals and can be a liquid, solid, or gas. The notation is: velocity averaged across the stream u, water depth h, cross-sectional area of the stream A, wetted perimeter P, and bottom slope S = sinθ. Daylighting can create new habitat for plants and animals, potentially reduce flood risks, and create new ‘green corridors’ through urban areas, a good example being the highly successful restoration of the Cheonggyecheon stream in Seoul, South Korea. Solar energy drives photosynthesis that supplies carbon (chemical energy) for the rest of the system. Boost Ecology By depriving the water of sunlight, buried watercourses become ecological deserts, devoid of any natural life. For example, physical factors such as climate, land topography, bedrock geology, and soil type influence the amount of water flowing in streams and discharging to lakes, as well as the types of materials (chemicals and particulates) found in the water. 3.
