The freshet is basically a flood that occurs because of heavy rainfall or because of the melting of a snow.
This type of flooding is most common in the valleys of the larger rivers, especially the ones that start their flow high in the mountains.
The large rivers have much more water, and they also have lot of tributaries, so when there's a heavy rainfall they receive enormous amounts of water, which easily causes a flood.
Also, when the snow melts, lot of water is released from it, and most of that water gets into the river, or first in its tributaries and that in it, so there's a high possibility of a big flood occurring suddenly.
Corporations are often accused of despoiling the environment in their quest for profit. Free enterprise is supposedly incompatible with environmental preservation so that government regulation is required.
Such thinking is the basis for current proposals to expand environmental regulation greatly. So many new controls have been proposed and enacted that the late economic journalist Warren Brookes once forecast that the U.S. Environmental Protection Agency (EPA) could well become "the most powerful government agency on earth, involved in massive levels of economic, social, scientific, and political spending and interference.
But if the profit motive is the primary cause of pollution, one would not expect to find much pollution in socialist countries, such as the former Soviet Union, China, and in the former Communist countries of Eastern and Central Europe. That is, in theory. In reality, exactly the opposite is true: The socialist world suffers from the worst pollution on earth. Could it be that free enterprise is not so incompatible with environmental protection after all?

- The azimuth of the sun is the angle of the sun's position defined by the relative direction along the horizon. However the most commonly followed convection for analyzing the sun radiation is 90 degrees east, south 180 degrees and west is 270 degrees.
- As sunrise and sunset are defined by the upper limb of the solar disk. These conditions produce patterns of night and day as the sun appears to move just above the horizon at an angle of 0.39 degrees per day as the equinox passes.
