I am not sure what you are referring to but if is the leaves falling from trees, Cover the pond.\n    I have a medium size pond I put under a large magnolia tree. I like the looks and waterfall sounds of running water as well as the smell of the tree flowers.\n\n     I built a frame out of PVC piping. Covered the top with a silver tarp. I then got very heavy duty black screen (the kind that is dog scratch proof) and attached to the sides to hang bout half way down. I even layed a screen cover across the pond for the birds.\n    That way, the leaves don't get in, the water don't evaporate so fast from the sun, the algae don't grow, the birds can drink/swim without drowning and I still can get a full view.\n     If you don't want to build a frame (like a gazebo) then take the heavy duty screen, anker it on the sides with heavy rocks. Then when the leaves collect, remove the rocks from 3 sides and just pull the screen to the ankered side and the leaves fall out on the ground.

with a big box and styrofoam blocks to suspend it in the middle.  Stab the ends into the styrofoam blocks and put a couple in the middle, sides and deck.  You can get them at the back door of a furniture store.

That would be a natural levee.\n\nWhen the river's water exceeds its banks, the water begins to slow down.\n\nThe slower velocity will cause the heaviest of the sediments to "fall out".\n\nSome of the sediment will be deposited on the banks of the river forming a natural levee.

The Official website for the Tower leans beacuse of layers of clay and water under the Tower.  It was closed for several years in the 90s to reinforce the foundation.  It has reopened to visitors and currently appears to be stable.

Wood doesn't survive well for 2000 years...

chuck a body down there and listen for the thud. if you hear no thud then it's bottomless. if you hear one you can gauge the depth off of how long it took to hit.

if its somewhat large, or near something very important, i would recommend going to a local geotechnical/ civil engineer.  \n\na few hundred bucks may be worth it not falling over, and then you are out the wall and the money.  better safe than sorry.\n\nan engineer will review site and soil conditions to give you a quality end product, and a guarantee

Wood blocks absorbing water is no doubt is imbibition.Imbibition is the diffusion of water molecules through any dead wall,.This is evident in case of dry seeds absorbing water. \nAdhesion is the attachment of water molecules to the cell wall.Cohesion is the attachment of water molecules with in them selves to make a water column. IN water absorption process, these two forces act and conduct water in up ward way against gravity.\nthe same thing applies to wood blocks also , offcourse they are immersed here\nThe same thing happens in the wood block,of course are immersed in water\nThese water molecules are bonded with in them selves by cohesive forces and they are attached to xylem wall by adhesive forces to form a water column in side xylem vessels\n.Because of these forces the water travels to the tip of very tall trees and of course to the branches also

Ok, look at it like this. What would happen if ever fawcet handle in your house popped off from ever sink and bathtub? \nWater would fill the sinks and bathtubs, then over flow. Before you know it your house is flooded and the structure becomes unstable and eventually breaks down. The water are imigrants. The fawcets and handles are imigration quotas and the house that breaks apart at the foundations would be this country. Ever hear of the saying, "Too much of anything isn't good"?
