Hydraulic calculations of storm sewer networks [PDF]
E3S Web of Conferences, 2020 Surface run-off (SR) produced on the territory of cities and other settlement as a result of atmospheric precipitation is an intensive source of the technogenic pollution of environment, including the waterbodies.

Storm sewer pressurization transient – an experimental investigation [PDF]
Journal of Hydraulic Research/De Recherches Hydrauliques, 2014 ABSTRACTPipe pressurization is examined experimentally by 144 laboratory experiments in a circular tilting pipe between two tanks, in which the transient was triggered by sudden closing of the downstream tank outlet. The experiments cover ranges of values of slope, velocity and filling ratio of the open-channel flow not explored in previous studies ...

Research on Urban Waterlogging Disaster Risk Assessment Based on ARCGIS and MIKE FLOOD – A Case Study on Shijiazhuang [PDF]
Journal of Risk Analysis and Crisis Response (JRACR), 2015 Urban flood risk assessment supported by accurate and precise modeling could make great contributions to urban flood management. In this paper, an urban drainage system model of Shijiazhuang city was built based on the MIKE21, MIKE URBAN and MIKE 11 ...

On the sensitivity of urban hydrodynamic modelling to rainfall spatial and temporal resolution [PDF]
Hydrology and Earth System Sciences, 2015 Cities are increasingly vulnerable to floods generated by intense rainfall, because of urbanisation of flood-prone areas and ongoing urban densification.

Contemplation of Improvement Efforts to Manage Combined Sewer Overflows
Infrastructures, 2023 Combined sewer overflow (CSO) is a significant environmental concern and public health risk (e.g., water contamination, eutrophication, and beach closure).

Analysis and calculation of sediment scouring rate at different locations of storm sewer
Water Science and Technology, 2021 To explore the migration differences of sediments at the front, middle, and end sections of a storm sewer when scoured by water, and further evaluate the pollution load, the scouring process of sediments at different locations of a storm sewer was ...

Sewer subsidies from overflows and pipe leaks dominate urban stream solute loads in all storm events
Frontiers in Environmental Science, 2023 Stream channel burial drastically alters watershed flowpaths by routing surface waters underground and increasing the potential for interactions between stream water and urban infrastructure such as storm and sanitary sewers.
