Relationship between flow, Precipitation and turbidity, for the Red Cedar River

In measuring turgidity and filtration of the river water sample, the procedures included, first the river water sample was collected from a Farm Lane bridge. Secondly, filter papers were obtained from stack and placed on the manifold followed by screwing the filtering cup down tightly in order to avoid leaks. As a third procedure, a vacuum was turned on followed by measuring out 0.5L of water at a time, which was then placed into a graduated cylinder while carefully pouring it into the filter cup. Water was added to the cylinder until when the filter paper turned brown. Water from both flasks was emptied after every use. Thirty filter papers were then placed labeled metal dish. This was followed by placing the metal dish with the filter into a drying oven. It was then that the filters were tried for a period of 24 hours. Finally, with the use of a metal weighing dish, the weight of the dried dirty filter was recorded.

Summary

Turbidity measures the light-scattering properties of water. It is therefore, an index of the total amount of suspended particles. In a stream run off, suspended particles might result from a number of human and natural management related sources that might include road related sediment, stream bank erosion, agriculture or urban runoff and other natural management-related causes…

Immunology - Flow Cytometry and ELISA
Flow Cytometry is a technique with automatic sorting devices that is able to sort successive streams of droplets into various fractions based on the type of fluorescence emitted by the droplet (Lee et al,1999).In this experiment, sandwich ELISA and Cytometry were employed; For sandwich ELISA, it was used to measures the antigen quantity between two antibody layers.

Open Channel Flow
Also, the hydraulic grade line is assumed to be at the surface of the flow. The flow in open channel flow is classified as steady or unsteady. The steadiness or unsteadiness of the flow is greatly dependent on the velocity of the flowing fluid, the discharge and the flow depth.

Impact of Flow Rate on Water Quality of the River Yare
Since the accumulation of organic matter is inversely proportional to the flow rate velocity of the water, this study will analyse and compare samples from two distinct flow rate areas. River conservation efforts of the past several decades have been aimed at reducing nutrient enrichment from fertilizers and sewage.
