Low Flow Testing, Daniel J. Howes

BioResource and Agricultural Engineering

In arid environments, streamflow enhancement in low flow channels is common. It is challenging to assess enhancement project effectiveness in these channels because of uncertainties in metering (regarding both meters and procedures). The basic equation for flow is:

Q = VA (Eq. 1)

Where,

Q = channel flow rate (e.g., cubic feet per second, CFS)

V = cross sectional average velocity (e.g., feet per second, fps)

A = cross sectional area (e.g., square feet, ft2)

There are three main factors that impact flow measurement uncertainty in natural channels:

1. Flow meter velocity measurements (V)

2. Depth and area measurements (A) …

Cichlid Size Vs Flow Rate, Amy E. Naumovski

STAR Program Research Presentations

Cichlids are a diverse group of fish that are known for their prenatal and postnatal care of their eggs and frys (baby fish). This unique characteristic creates a limitation on the amount of eggs a cichlid can lay and protect, which is particulalry effected by the size of the eggs. Cichlids have a large variance in their egg size, which correlates to a large variance in their fry size. This project explores the trade offs cichlids make in egg size and fry size by specifically testing the ability of varying sized cichlids to swim in different flow rates. This could …
