Water Quality Research (contd)

• What is the effect of riverbed composition on
  water temperature in sites 3 and 5?
• Experimentally water above concrete is cooler
  than water on wet soil
• Possible Explanation? Physical properties of
  materials
• Theoretically According to their heat
  capacities, water above concrete should
  experience a higher T increase
• Conclusion Riverbed composition (Heat Capacity)
  is not fully responsible for water temperature

Expires 600 AM EST on February 24,
2006 Statement as of 1113 AM PST on February 23,
2006 A Wind Advisory remains in effect from 9 am
to 6 PM PST Friday. Strong northerly winds of 30
to 35 mph with gusts up to 50 mph are likely
across the advisory area on Friday. Very wet
conditions combined with the strong winds will
likely lead to areas of blowing foo... especially
near open fields. The foo may decrease
visibilities on Interstate 8 to around 1 mile or
less at times.

• Continuous data will not be accepted for at least
  a year
• System should check data validity
• Data should be exported to Excel template until

8.3 cm 5) Input Module (FP-AI-110) and Input
Module Plug FP-TB-1 )
35
SolidWorks Design of the Enclosure
36
Diameter of the Hole on Enclosure
-Based off the diameters of the sensors, the
estimated size of the hole will be about 10
cm Diameters of each of the sensors
The conductivity sensor (WQ 301) 2.5 cm
The water level sensor (WQ 101) 2.2 cm diameter
The pH sensor (WQ 201) 3.5 cm diameter
The dissolved oxygen sensor (WQ 401) 3.5 cm
diameter
The temperature sensor (WQ 101) 2.2 cm diameter
37
Conduit Design 1

• Each sensor in its own individual conduit made
  of PVC pipes

• The end of the pipe needs holes to
• allow water flow to the sensors.

• Level sensor needs a stilling well

38
Conduit Design 2

• Each sensor is in its own conduit.

• However, a 3.5 diameter pipe
• will compactly house all 5 conduits

• Split at the bottom
• One that provides water flow
• One that creates a stilling well

39
Pros and Cons

• Design 1
• Pros
• Cost (86.02) ? half the price the other design
• Easy cleaning
• Cons
• Noticeable
• Ascetically less pleasing

• Design 2
• Pros
• Takes up less space
• Less conspicuous
• Cons
• Twice the price (191.05) as design 1
• One extra step for cleaning
