Product description: Surface runoff is the flow of water that occurs when excess water from rain, meltwater, or other sources flows over the earth's surface. This might occur because soil is saturated to full capacity, or because rain arrives more quickly than soil can absorb it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water. QT series tipping bucket flowmeter can be used to monitor no-pressure, low-head, and small discharge flow of surface or underground runoff.
