| | Summary: |
| | Due to increased urbanization and significant alterations of natural drainage catchment accompanied by climate change, there has been an increase in runoff due to reduced infiltration and increased flood risk in urban areas. For several years now, as part of the solution, green roofs, permeable pavements, and rain gardens have been proposed to increase infiltration while reducing overall runoff from urban surfaces. In order to effectively manage rainwater, in addition to water quality, monitoring is necessary, including flow measurement. To date, a large number of measuring device and instruments have been developed to measure the quantity of rainwater runoff. One such measuring device has been constructed in the hydraulic laboratory at the Faculty of Architecture, Civil Engineering, and Geodesy at the University of Banja Luka. This is an inexpensive and practical device for measuring rainwater flow, constructed from PVC drainage pipes, using a "V" weir as an overflow, commonly known as a Thomson weir. Laboratory testing of this measuring device has been conducted to identify parameters affecting the overflow coefficient to achieve greater accuracy in measurements. A total of five different equations for calculating the discharge coefficient have been proposed, depending on the geometry of the weir and flow conditions at the weir. |
