Physically-Based Particle Size Distribution Models of Urban Water Particulate Matter

Role of height and position in the vertical distribution pattern of urban surface-deposited sediments and associated heavy metals

“…[34][35][36] Consequently, a proper understanding of the dynamic variation of the grain size composition of RDS during a long dry period is essential for managing diffuse urban pollution generated by surface runoff. [59][60][61] It is well-known that RDS reached mass dynamic equilibrium in about 7-9 days after the last rainfall event and then the proportion of finer particles (<100 μm) gradually increased with increasing dry weather. 9,62,63 However, there is a lack of research on the USD build-up process of various sized particles during a long dry period.…”

Pollution and ecological risk assessments for heavy metals in coastal, river, and road-deposited sediments from Apia City in Upolu Island, Samoa

“…Suspended particles, which account for a large portion of the stormwater runoff, can accumulate high concentrations of organic matter and heavy metals. Therefore, it is important to manage non-point pollution sources derived from precipitation consistently (Liu and Sansalone, 2020;Jeong et al, 2020a;Zhang et al, 2021).…”
