how can i measure the hight of wave in a shallow pond?

You could place a vertical rod in the pond (on a stand or stuck in the mud?) and start the experiment when the rod is dry.  After you create the wave and the surface returns to rest, measure the height of the wave on the rod.  This will be the maximum height of the waves at the given point and will depend on the location of the disturbance (radiates outwards like a bullseye?).  Also, there should be nothing near the rod to magnify the wave (including shore effect or irregular bottom?).  Applying chalk to the rod (especially blue chalk?) may make the wetted height more visible and resist drying too fast.  Including a scale on the rod may allow you to read the wetted height above calm surface easier, especially using binoculars.  The trough should approximately equal the wave height.  Good luck.

measure the size of bowl(better if rectagular or square) and time how long it takes for waves to hit the sides for one minutes. about 10 waves. multiply by 60 to get speed/hr

Yes with a gaussmeter.

The pond is not likely round enough or a pedometer accurate enough for more than a rough estimate.\n\nA better alternative would be to use Google Earth.  It has a measuring utility that lets you define your path and will tell you distances more accurate than the above.\n\nGood luck.

Surveyors have equipment that does that.\n\n If you need a rough # you can stand back and use a fixed item like a person (at that same point) use it as a baseline with a scale measure the person and then measure the tank take the # of time you repeated the scaling and multiply it by your know distance. Its rough but will get you close.

i haven't done this in a while.\n\nThe volume of the reservoir is equal to (1/2)*(height)*("base")*length.  the reservoir is a rectangular prism with the "base" being the distance across the surface of the water.  We are given the shape of the full volume so we can scale down to the level of the water to find what the volume in the reservoir at its current level.\n\nif you think about the cross-section of the volume, and use half of that forming a right triangle, we can determine the ratio of the surface (the "base") to the height (water depth).  In this case, it is (40/2)/(20*sqrt(3)) or 1/sqrt(3).  so ("base"/2)/(height) = 1/sqrt(3)  and then "base" = (2*height)/sqrt(3).\n\nsubstitute that into the volume equation so that\nvolume = [(height^2)*length]/sqrt(3) or literally,\nV = [(h^2)*L]/sqrt(3).  differentiate with respect to time,\n(dV/dt) = [2*h*(dh/dt)*L]/sqrt(3) and substitute the numbers in:\ndV/dt = 200 - 50 = 150\nh = 10*sqrt(3)\nL = 450\nand solve for dh/dt which is the rate of change of the water level in yds/hour.  these are odd units, you might want to change to inches/hour.\n\ni did it this way and got 1/60 yds/hr or 0.6 inches/hr.\n\nbut again it has been a long time....

Cover one end of your garden hose with clear plastic (like Saran Wrap) and wrap rubber bands around it to hold the plastic in place.  Then remove your garden hose from the faucet and cover the faucet end of the garden hose with plastic wrap and use rubber bands to hold that in place as well.  Lay down the garden hose over a relatively flat area of the ground where you wish to determine level elevation.  Then look at each end for air bubbles.  (Make sure the garden hose isn't draped over a hill, or this procedure won't help.)\n\nIf you find air bubbles at one end of the hose, it means that end is at a higher elevation than the other.  Move the bubble end of the garden hose, without moving the other end until the bubbles leave the plastic.  Then check the other end of the garden hose.  If you find bubbles, move that end only until the bubbles leave the plastic.  \n\nRepeat this procedure until you don't see bubbles at either end.  That is when the ground is level along the length of the garden hose.

find a mountain, hill, or other land area that is elevated, that collects water.\n\nDig a trench, or path, so the extra water flows through it.\n\nMake sure the path you dig goes into another body of water, like a pond, lake, or other water area.

OS maps with contours will do the trick to a reasonable accuracy. If you want real accuracy you will need to level to the nearest OS bench mark or get a GPS reading from an instrument which gives height as well as grid location.\n\nFurther info after reading another answer.\nI am talking about UK here where the ground levels can change quite dramatically from street to street unlike the previous US respondant who must live in a very flat area of the States.

If the antenna is mounted the best way is to use a plumbob and a bubble level gauge. Or just the bubble level gauge with degree increments labeled. another way is to use a compass and a square against the front of the antenna. Hope this helps.

sea level is easy to measure. If the water is suddenly a lot closer to the road next to the beach, you know the level has risen. If it is suddenly a half hour walk across the mudflats to get to the water it has dropped.\n\nWe also have these things now called satellites, maybe you've heard of them. They are good for measuring the position of things very accurately. If they say the ocean is now bigger and the land is now smaller, well I for one would believe it.

This depends on numerous factors.\n\n1-Depth of the pond\n2-Temprature outside\n3-Dimensions of the pond\n\nTaking in the considerations, using some math, you might be able to come up with an answer!

Measuring the height of a wave is typically based on lowest to highest (after all, the wave could start at any point on the wave!)  The technical term for the vertical component of a wave is the amplitude, which is the average of the lowest and highest points of the wave.

Any size. Some tsunami are like 4 feet tall. Some are 16-feet tall.
