Answer:
Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth.
Explanation:
Disturbances such as fires, windthrow, or even debris torrents can influence stream temperature, turbidity, and other water quality parameters. Geology, geomorphology, and climate also influence water quality.
Increased volume reaching the streams and waterways can, in turn, lead to more flooding during storm events and reduced flow in streams during normal or dry periods. The reduced amount of infiltrating water can lower groundwater levels thus lowering the baseflow found in streams during times other than storm events.
