Translate the sentences into Russian.
1) The discharge of water from the reservoir is carefully controlled.
2) There was water seepage through the roof of the tunnel.
3) This reservoir was limited in its storage capacity to meet the growing demand for water.
4) This graph shows a trend of decreasing storage capacity during the first half of the year, and then increasing or stabilizing during the second half of the year.
5) The effects of tornadoes are devastating.
6) In physics, velocity is speed in a given direction. Speed describes only how fast an object is moving, whereas velocity gives both the speed and direction of the object's motion.
7) Permeability in fluid mechanics and the earth sciences is a measure of the ability of a porous material to allow fluids to pass through it.
8) You should use one of the numerous websites that are available for researching precipitation rates.
9) The effect was too negligible.
