Alright, I guess since this died I'll take my turn:

List three assumptions made by the hydrogeology challenge, and explain how they fail to predicts groundwater movement in reality.
Now that spring break is over
```1. Pumping wells completely change the groundwater flow. Reality is wells have limited impact area.
2. Water moves through single layer of strata. Reality groundwater moves through all layers of rock and soil and not just a single layer.
3. The water tables is assumed to be a perfect plane. The triple point use of hte challenge gives one line of equal elevation and flow direction and is not universal with the whole area.  It also assumes gradient is constant but its only the average slope between two points. The gradient isnt constant between two wells and changes based on the elevation of surroudning area and whether pumping exists(cone of depression)```

Correct.

The format for hide function is to have Title | Content
