what exactly is hydraulic gradient? and how does this have to do with Darcy's Law?

The hydraulic gradient is the change in height of hydraulic heads over a certain distance. Click here. A hydraulic head is basically a measure of the pressure groundwater is exerting; it can be measured by comparing the height the water in a well reaches (see diagram) with a reference point such as sea level.

Darcy's law calculates the speed of groundwater flow. It basically says no hydraulic gradient, no flow. Groundwater flows from high pressure to low pressure, and the steeper the gradient, the faster the flow.
ornithology, forestry, entomology, triple E, green generation, water quality, dynamic planet (lakes & rivers), awesome aquifers, meteorology, robot arm, write it do it. :)
A cone of depression occurs when you drop your scoop of ice cream on the ground on a hot summer day.

What stuff about shorelines and waves in lakes do we need to know? And should we know all the types of currents found in lakes? Also, is the only important thing in the hydrologic cycle the terms, or do we need to know percentages or anything?

If I were you I'd get some percentages and numbers on the resource, since the manual does cover water budgets. Besides, you never know what'll come up on these tests. Just make them take up as little space as possible.

does anyone know some websites that talk more in depth about subjects for Dynamic Planet? I need some detailed information for my cheat sheet, which is only halfway- done.

I use http://www.tulane.edu. You may have to sift through the website for the stuff, but its under a professor who posts his notes online. It's a geology professor-I'll post where it is once I find it.

I'd suggest googling every word on the rules manual. :)
You can get some pretty decent stuff:
http://www.uwsp.edu/geo/faculty/ritter/ ... tents.html
http://egsc.usgs.gov/isb/pubs/booklets/symbols/
http://streams.osu.edu/book/lectures.php
http://www.lakeaccess.org/ecology/lakeecologyprim9.html
http://www.eoearth.org/
http://pubs.usgs.gov/circ/circ1139/htdocs/boxa.htm
http://www.dyersburgtn.gov/stormwater/swm_streams.pdf (best overview of the topic for sure)
http://www.tulane.edu/~sanelson/geol111/
I'd also wikipedia every word on the rules manual.

It's a lot of info to memorize and sift through and copy onto the manual, but that's how to get better, I guess.
