What is a water table in geography?
The water table is a fundamental reference surface in the study of groundwater. It tends to follow the ground surface, rising under hills and falling at valleys, but the gradient of the water table is usually much less than that of the ground surface (Figure 4). Figure 4 The water table.
What is water table and how it is formed?
Water table is formed when rain water and water from the other water bodies on the surface of the Earth seeps down into the soil and is stored as ground water. This passing down of water through the soil is known as infiltration.
Are water tables safe?

What is groundwater and how does it relate to the water table?
What is groundwater, and how does it relate to the water table? Groundwater is water that occupies the zone of saturation within the ground. The water table is the upper limit of the groundwater.
What is water table what is its significance in crop production?
High water tables restrict crop growth and nitrogen uptake by roots. Soil water contents below field capacity increase the rates of all processes, except denitrification. Saturated conditions due to higher water tables enhance denitrification.
What is high water table?
That said, a high water table refers to a state when the rock and surrounding ground materials join the upper soil layer due to an excessive amount of water beneath it. This phenomenon can occur when there’s heavy rain in the area or when the water from higher elevations spreads into the soil surrounding your home.

Groundwater is dynamic natural resources that can be recharge most during the rainy season by the rainwater for the rest of the year. Over withdrawal of groundwater causes decline in the water table due to the stress and distorting the aquifer and may also leadadverse surface and subsurface environmental effect [2].
