| 1. | This is called the Klinkenberg effect, and it is especially important in low-permeable rocks.
|
| 2. | Ice will form in water-permeable rock in much the same way as it forms in soil.
|
| 3. | In 2001 another borehole was drilled at a new location, further from the road, into the gas-permeable rock.
|
| 4. | They are formed when heat from the caldera encounters water in permeable rock and pressure builds, venting steam.
|
| 5. | Along the lower McKenzie, however, winter rain slides easily off the less permeable rock and erodes sediment into the river.
|
| 6. | Once water creates a channel through the permeable rock to the producing wellbore, there is little benefit in injecting additional water.
|
| 7. | During the process, fracturing fluid leakoff ( loss of fracturing fluid from the fracture channel into the surrounding permeable rock ) occurs.
|
| 8. | Below the water table, in the phreatic zone ( zone of saturation ), layers of permeable rock that yield groundwater are called aquifers.
|
| 9. | The rainwater is absorbed by the ground and is filtered through hundreds of feet of soil to a layer of permeable rock that holds the water.
|
| 10. | A permeable rock seawall ( called " kuap " in mullet ), which reproduce in the ocean but can live in either fresh, brackish, or salt water.
