Water Systems

Human and Natural Factors that change the water table.

Human Factors

When human clear cut forest it creates erosion and a higher run off that carries water away before it can be absorbed into the ground. This affects the water table because if not enough water is getting absorbed and it isn't raining as often the table gets lowered. In addition when humans over use their wells it causes a huge problem because the water must not only "feed" the plants but extra water must go to the well to keep water available. With this happening the plants a grass near by will not have as much "sustainability" because of the over usage. In addition if humans have a oil leak in their car and it runs to the lawn it will contaminate the water. With the water being contaminated it will affect their well water and the "green" area around them.

Natural Factors

The type of soil affects the water table. If the soil is high in clay it is more permeable but if there is more sand it allows the waster to pass through which raises the water table.

If a drought happens the water cycle brakes. There is not enough precipitation to keep the ground moist. Therefore the water dries up and there is a limited supply of water to the ground. which makes a limited amount of water to people who use wells as a water source. When a flood happens it does the complete opposite. There is too much participation and not enough evaporation. When this happens the water table has too much water so it must over flow causing water to lay on top of the earth and become contaminated.
