Description

Apparatus and Method for Building a Turbidity-Suspended Sediment Relationship Library Using a Circulating Water Channel The present invention relates to a technology for calculating turbidity-suspended sediment relationship equations, and more specifically, to an apparatus and method for constructing a turbidity-suspended sediment relationship equation library using a circulating waterway. Suspended sediment is a general term for sediment such as clay, silt, and sand that rises from the bottom and moves into the water due to water flow or waves in dams, reservoirs, and rivers. Recently, with the increase in concentrated rainfall caused by extreme weather events, predicting the occurrence of large amounts of turbid water due to suspended sediment is becoming increasingly important for ensuring the water health of water sources. When investigating the status of turbidity caused by suspended sediment, conventional methods involved measuring turbidity with field sensors and obtaining suspended sediment data through actual sampling to calculate the relationship between turbidity and suspended sediment; however, this approach had the disadvantages of requiring significant time, manpower, and cost, as well as a low measurement frequency. Generally, since a linear relationship exists between turbidity and suspended sediment, turbidity-suspended sediment equations have been calculated and used; however, conventional equations calculated through intermittent sampling at specific points and times did not reflect turbidity significantly influenced by the suspended sediment fraction, posing a problem in predicting the occurrence of river turbidity that changes according to rainfall intensity, duration, and topographical changes.
