Dear alls my name is Costanza Aricò, and I'm a first year Ph.D student at the department of Hydraulic Engineering at the University of Palermo, Italy Actually I'm introducing my research work about sewer sediment transport model. As first step, I'm studying on several articles (found on ASCE HY) about longitudinal (1-D) dispersion coefficient, but all studies concern the case of rivers and not sewers. Do you know any research work or any person who worked about dispersion movement in sewer ? How may I find papers about dispersion in partially filled sewers ? See You and best luck Costanza Aricò
