As rain water seeps into the soil it creates a pressue on the water that is already underground. The force of this pressure causes the water to flow through caverns and develop springs, creeks, and rivers.
Water can move through sand without moving it. At least half of Florida is sand, the other half is limestone. Water has no problem moving through the sand without moving it.

It can flow like a river when in a cave, or it can seep along when held by a porous medium. Picture a bucket of sand, and the bucket has a screen bottom. Pour water into it, and the water flows slowly through, and the sand remains in place. Just like on the surface, water flows downhill. When the water emerges onto the surface under pressure caused by the water table being above the point of emergence (tilted strata with non porous cap and base rock), you get an artesian spring.

Actually sand is a great filter. Will it flow through sand without moving the sand? Depends on the rate of flow and the density of the sand grains.

Water flows around and between the sand grains. There doesn't have to be any cracks or caves.
All you have to do to check this out is to do this: Fill a styrofoam cup with water and then pack the cup with sand. Finally, punch a hole in the bottom of the cup. You will find the water flowing out of the cup.
A second way is to take a cup packed full of sand and then slowly run water into to the top of the cup and wait for the water to run out the hole in the bottom. The finer the sand and the harder you pack it in the cup, the longer it will take the water to run out.

water like electricity follows the path of least resistance, such as joint sets, mud seams, and thru whatever the geology of the strata is, and yes it will move sand and over time cut thru rock

it is a pressure and errosion process.water is the strongest force of nature.
