Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a portable surface runoff collection and measurement device. Background Art

[0002] Surface runoff generally refers to the flow of water formed by precipitation or melting of ice and snow that flows into rivers, lakes or oceans along different paths in the basin. Surface runoff is an important part of the hydrological cycle and a fundamental factor in the change of river hydrological conditions. Surface runoff is affected by environmental factors, so it can be used to study and analyze ecological environment such as soil erosion.

[0003] Most of the existing surface runoff collection and measurement devices are built or fixed on the ground, which have the disadvantages of high installation cost, inconvenient movement, and easy damage to the environment. They are not suitable for the measurement of surface runoff in the field, especially on mountain slopes. In addition, the collection and measurement of existing surface runoff collection devices are often carried out separately, and the operation steps are relatively cumbersome. The device itself does not take protective measures against rainfall. When it rains, rainwater will flow into the surface runoff collection and measurement device, and its measurement accuracy will produce different errors according to the amount of rainfall.

[0004] Therefore, it is necessary to provide a portable surface runoff collection and measurement device to solve the above technical problems. Utility Model Content
