UV absorbance of suspended sediments measured in a laboratory using a submersible spectrophotometer

This dataset contains information about submersible absorbance sensor responses to varying suspended sediment concentration, grain size and organic content. Laboratory tests were conducted at the University of Birmingham, UK, during 2023 as part of a wider study developing methods for urban storm flow characterization. Two sediment types were assessed along with three size fractions across concentration ranges from 0 mg/L to 5000 mg/L. Absorbance was recorded at key wavelengths between 190 – 360 nm and particle size distribution and organic content (loss on ignition) measured for each sediment type and size fraction.

The work was supported by the Natural Environment Research Council (Grant NE/X011178/1).

本数据集收录了浸没式吸光度传感器（submersible absorbance sensor）在不同悬浮泥沙浓度、粒径与有机质含量条件下的响应数据。相关实验室测试于2023年在英国伯明翰大学开展，作为一项旨在开发城市暴雨径流表征方法的综合性研究的组成部分。本次测试共评估了两种泥沙类型，并覆盖三种粒径组分，悬浮泥沙浓度的测试范围为0 mg/L至5000 mg/L。研究人员在190 nm至360 nm的关键波长下记录了吸光度数值，并针对每种泥沙类型与粒径组分测定了粒径分布与有机质含量（烧失量，loss on ignition）。
