How Japan Filled That Ginormous Sinkhole In Just One Week: The Fukuoka sinkhole measuring 8,700 square feet (808 square meter), 65 foot (20 m) deep: they poured a mixture of soil, water, and cement into the hole—they use more than 7,100 cubic meters of the stuff in all.

Your question has an incorrect assumption built in. Near surface ground water temperatures are not generally colder, but rather reflect the average annual temperature. This will be colder than surface temps in summer, but warmer in winter. There is an an additional effect if your rainfall isn't evenly distributed over the course of the year, as percolating ...

Aquifers are relatively permeable zones of material that transmit water. Common aquifer materials include layers of unconsolidated sedimentary rock, like sands and gravels; and poorly cemented “bedrock” units like sandstone. Interconnected solution cavities in limestone, called karst, are common in some areas. Calling something an “aquifer” generally infers ...

If it’s hot enough to alter the groundwater chemistry that is killing the trees, then you would see it in satellite thermal imaging. Remember, tree roots only go down about 20 to 30 feet at the most, so this is all pretty shallow stuff. This is actually quite a strong thermal anomaly. Like you said, the heat alone may have killed the tree/tree roots.the ...

This is already used in some cases. The one I'm familiar with is California's Coachella Valley, best known as the home to Palm Springs. Farms, golf courses, other businesses, and homes pump far more water out of the region's aquifer than is restored by normal rainfall, so the Coachella Valley Water District pipes in water from the Colorado River and, ...

The temperature would stabilize to a steady temperature when you go down 15 ft or so. The point where it gets significantly warmer is probably much deeper than you want to go. A better system would probably be to bury two separate loops that are 6 or 8 ft deep. One is the heat loop on one side of the house and the second could be the cool loop on the ...

Analogues to Mars Recurring Slope Linea (RSL) is a current study topic in Antarctica (Dry Valleys). On Earth, analogues are known as water tracks, which are linear zones of higher moisture along slopes in polar regions where water transit during snowmelt. This figure from Ward Hunt Island (NU, Canada) show well developed and typical water tracks. Source: ...

Groundwater data are collected from wells, as described in arkia's answer. I'll amplify on that answer. The driller or geologist describes the type of sediment encountered when drilling a well. Sometimes sediment samples are collected for analysis of grain size. Core samples aren't typically collected but may be for special studies. The type of sediment ...

USGS conducts regular survey in over 20000 wells across the United States. The frequency of data collection depends on the site with around 7000 providing daily data. For some of those wells (currently, 3777 groundwater sites) daily statistics are provided. An increasing number of wells are providing real time (updated every 15 or 30 min) data. Source: ...

This is due to the presence of iron sulfide in the water. The iron sulfide oxidizes and goes into solution. Ferrous iron oxidizes to ferric iron. Depending on the water chemistry, this commonly precipitates out as orange-coloured iron oxyhydroxide, but that does not seem to be occuring in your case, otherwise you would see it. When it does happen, the pH of ...

It depends on the size of the aquifer and the amount of precipitation falling on the exposed areas of the aquifer. These have been used to provide water form many major cities. The Trafalgar square fountains were initially powered by artesian pressure (as London is below the altitude of the North downs / Chilterns). Eventully too much water was extracted ...

Aquifers are detected by boreholes or by water divining. Water divining is a very unscientific method which so far has no rational explanation, yet is often successful. I put this down to the fact that Britain is such a wet country that wherever you drill a borehole you are almost bound to discover water sooner or later. Perhaps a more scientific explanation ...

First of all, the rocks do not disappear they dissolve, so they are still there only dissolved into the liquid. You are using an acid (vinegar), this has a low pH. The rocks you are using (limestone) they have a high pH (alkaline). The alkaline rock you add to the acid will dissolve but only until the acid is neutralized. The reaction stops when the pH ...

Be aware that ducts lack the filtration process that bedrock often affords, and that you may introduce raw materials that are toxic to some of the ecosystem for the lake/etc. As long as that's not an issue, then there's no implicit reason you could not. If you try to use geological formations for channeling the underground water, you suffer the risk of ...

1) I don't believe there is a fully global map as some parts/countries of the world are inaccessible for varying reasons; however, there are a number of maps available for areas around the world. 2) Possibly, but it depends on a few factors. I think the cost would exceed the effort required to either reroute a subterranean river or produce enough pressure ...
