Ground Water Logged:
GRASS will not grow well in waterlogged soil. Its roots need air as well as moisture. The ideal is a film of water surrounding each soil particle and air in the spaces between. It is as though you dipped a bunch of grapes in oil or molasses, lifted it out and held it to drain. Around each grape a film of the liquid clings, even after draining, but there are considerable air spaces between the individual grapes. Except in swamps and bogs where free-standing water is at (or close to) the surface, this is the condition that normally exists in the upper soil. But if you dig down deep enough you will, unless you hit bed-rock first, come to a level below which the spaces between the soil particles are filled with water. The top of this free standing water—its surface, is the water table. Holes you dig fill with water to this level.In the event that your soil is waterlogged, if free water stands in the test holes closer than a foot to the surface for any lengthy period, it needs draining. Before you decide to install Tile drains check to see what holds the -water. It may be only a shallow impervious layer. In this case you should be able to relieve the trouble by busting through it with a subsoil plow or by spading deeply, provided, of course, that the soil beneath the impervious layer is porous. If the water-holding layer is too thick to break through, then an installed drainage system, provided you can find a suitable outlet, is the answer.
When the river reaches the sea the sediment it is carrying is deposited. In some areas tidal currents are strong enough to remove it and the river ends in an estuary. Where more sediment is brought down than can be removed by the sea a delta is formed [10]. Heavy and prolonged rain may make level ground water logged waterlogged. But once the rain has stopped, the ground water logged will dry out as the water sinks into it. In hot weather standing water will evaporate and plants will absorb water through their roots, transpiring it from their leaves. Sloping ground water logged drains quickly, for the water that cannot Sink into the ground water logged flows downhill in rills, then in streams and finally in rivers. That part of the rain that has percolated into the ground water logged will emerge later, at a lower level in the terrain, as a spring and flow away as a stream or river.
