What is the name of the concrete structures that slow water?

What your actually thinking of are baffles. These cause the water to travel in a zig zag way or even perpendicular to flow direction. This slows the water by taking its Kinetic Energy and so reduces wear on other structures or machinery

Among the possibilities, the foundation could be affected by compression from the damp and unyielding surrounding soil.  Extra drainage gravel around entire foundation may minimize foundation pressure fissures/cracking/collapse.\n\nHigh water table may require continuous or nearly continuous pumping to prevent flooding of basement or lowest level of structure.\n\nSlab construction, if possible, would eliminate below grade issues.

Depends on what you mean by types.\n\nDo you mean the type of material used in constuction or the type of activity the building is intended for.\n\nMost large building use a chilled water system where they use chillers to cool water down to about 42 deg F then pump the water throught the building to air handler units which blow air across the coils filled with the water.  This heats the water, but cools the air.  As the air is circulated throughout the area the water is returned to the chiller to be recooled and the process starts all over again.\n\nHowever, an important point is capacity.  That will be determined by both what the intended use of the building is and what sort of material is used.

Dead stop.  If it rebounds, it slows the following water, reducing spin.

The rivers are cresting and there is a lot of standing ground water that will slowly be absorbed or drain off.

Many (square?) cooling towers are open on all sides through wooden or fiberglas slates that allow air to enter and mix with the sprayed water to be cooled.  The water droplets partially evaporate giving up much of their heat then fall to the cooling tower basin below the tower where the "cooled" water is pumped back into the plant to extract more waste heat.  The water is recycled perhaps to extract heat from giant condensers to create very low pressures (partial vacuums) at the turbine discharge permitting the turbine-generate to generate far more electricity than if the turbine discharged directly to the atmosphere.\n\nHyperbolic (hour-glass shaped?) cooling towers perform the same function and likely are more expensive to build than cylendrical (or square) cooling towers but the advantage is that all air enters at the bottom of the cooling tower (not through the sides) and passes up through the entire tower height producing a "chimney" effect that strengthens the draft promoting better heat rejection.  The reduced diameter would increase air velocity (like a ventouri tube) to counter the downward pressure of the water drops.

If you're referring to a reverse flow due to natural OR artificial causes, the most noteworthy is the North fork of the South Branch of the Chicago River. This was reversed to have sewage flow down the Great Lakes/Mississippi waterway. The North Branch and South Fork of the South Branch were unaffected.\n\nSpeaking only of natural phenomena, there would, I am sure, be many. One I know of for sure is the Mekong, which is so close to sea level that the twice daily tides cause it to reverse flow and actually flow backward in some areas.

This depends upon how dirty the water is.  If the dirty water is clogged with material bits then that will slow it down.  If the dirty water is dirty in color only it should be equal.

to get the foundations over water, there are several ways to get the foundation for the bridge set up over the water.  one way is to float out a platform that is not unlike an oil derrick.  from there 'piles'(columns made out of concrete or steel)are driven down into the ocean floor and a foundation is rested and secured and built on it until you get to the top.  \n\nthe other way is (in shallower water) to build a 'coffer dam'  this is a temporary structure that you would build around the place that you want the foudmnation for the bridge in the water.  you put the dam around the area, pump out the water, and then build a foundation as you normally would, or even place piles like the example from above.
