The estimation of suspended sediment transport using nefelometric and traditional measurements of turbidity of water on an example of the cascade lower Brda River
Journal Title: Pedagogy and Psychology of Sport - Year 2016, Vol 2, Issue 1
Abstract
Abstract The evaluation of the suspended sediment transport was conducted on artificial reservoir of cascade of lower Brda River, to compare methods: traditional (weight) and nephelometric (optical). The analysis was based on field research conducted below the Smukała Reservoir in the years 2014 - 2015. These included sample collection for determining the value of total suspension (traditional method) and nephelometric turbidity of water (laser method). Sampling was connected with the observations of water levels, for specifying the hydrological situation. The collected data were interpreted using basic statistical methods. Was found that the the Brda River is characterized by a low suspended sediments load. Observations turbidity of water was possible to determine temporary dynamics of suspended sediments and indicate the main source of the suspended material. Received in article data indicate that the compare methods are interchangeability. Streszczenie Ocenę transportu rumowiska zawieszonego, dla zbiorników retencyjnych kaskady dolnej Brdy, przeprowadzono w celu porównania metod: tradycyjnej (wagowej) oraz nefelometrycznej (optycznej). Analizy dokonano na podstawie badań terenowych przeprowadzonych poniżej Zbiornika Smukała w latach 2014 - 2015. Obejmowały one pobór prób w celu oznaczenia wartości wskaźnika zawiesina ogólna (metoda tradycyjna) oraz nefelometrycznej mętności wód (metoda laserowa). Pobór połączony był z obserwacjami stanów wody, umożliwiając określenie sytuacji hydrologicznej. Zebrane dane zinterpretowano za pomocą podstawowych metod statystycznych. Stwierdzono, iż rzeka Brda charakteryzuje się niewielkim obciążeniem w materiał zawieszony. Obserwacje zmącenia wód, umożliwiły określenie chwilowej dynamiki zawiesin oraz wskazanie głównego źródła pochodzenia analizowanej składowej transportu fluwialnego. Otrzymane dane wskazują na możliwość zamiennego stosowania porównywanych w artykule metod.
