I'm not sure about the context, but the only time I've run into those questions have been when I've already calculated the groundwater velocity for part two. Otherwise, the only way I know of is to go back to part two and calculate everything again for that well.

Alright, let's reboot this thread.

What is the mathematical relationship between volumetric flow rate and cross-sectional area (aka directly or inversely related)? If I was to graph these quantities such that Q is on the y-axis and A is on the x-axis, what would the slope of such a graph be equal to, taking into account porosity?

Hint: Think about Darcy's Law

Volumetris flow rate is directly proportional to cross sectional area. The slope, would be equal to(included effective porosity) the velocity*crosssectional area*effective porosity.

Volumetris flow rate is directly proportional to cross sectional area. The slope, would be equal to(included effective porosity) the velocity*crosssectional area*effective porosity.

One problem: The slope is the volumetric flowrate over the cross-sectional area, so the slope would not be equal to v*cross-sectional area*porosity; just drop out the area term and it becomes v*effective porosity. Also acceptable for the slope is Ki, conductivity*gradient; this is the other side of the Darcy's law equation. Your turn!

Haha, that was a silly mistake on my part. (Click to Show Hidden Text)

My initial answer was Ki but then I saw the "taking into account porosity" portion of it, so I changed it. I'm dumb, I wrote the other side of the equation instead of just the slope of the relation.

Name and describe three types of wells.

Name and describe three types of wells.

I'm not sure this is what you're looking for but: Unconfined well- A well in an unconfined aquifer; water rises to water table level
Artesian well- Well in a confined aquifer; water rises to a height based on the pressure of the water in the confined aquifer called the piezometric surface
Flowing artesian well- An artesian well in which the piezometric surface is above the ground surface, causing water to rise above the ground

You're correct.

I wanted to go to more construction portion of wells like a [url=https://water.usgs.gov/edu/earthgwwells.html]dug, driven, and drilled wells[/url] as I've been seeing those question appear more often recently.

Your turn.

Explain the difference between In-Situ and Ex-Situ.

Question (Click to Show Hidden Text)

Explain the difference between In-Situ and Ex-Situ.

Answer (Click to Show Hidden Text)

In-situ means the remediation takes place at the site of contamination, and ex-situ means the contaminated groundwater has to be moved somewhere else (like to a treatment plant or whatever) to be remediated (or you have to excavate the contaminated area).
