Answer:
When it comes to constructing a well for water usage, one of the most crucial factors to consider is sediment types. In this activity, we aim to analyze the various sediment types and determine which would be the best for water well construction. In doing so, we will be able to identify the layer that allows water to pass through the easiest and which sediment layer poses a challenge to water passing through.
From our experiment, we observed that the sediment layer that water was able to pass through the easiest had both high permeability and porosity. Permeability is the measure of how easily water is able to flow through a medium, while porosity refers to the amount of empty space or voids within a material. The high permeability and porosity of this layer make it ideal for water well construction as it allows for efficient water filtration.
On the other hand, we observed that water had difficulty passing through the sediment layer with low permeability and low porosity levels. The output from our experiment was what we expected to see, based on the permeability and porosity levels of each layer. We confirmed that high permeability and porosity led to higher water flow rates and vice versa.
Moving on to the urban area, we noticed that when rain fell, water could not penetrate the impervious surface, and it resulted in surface runoff. This can lead to drainage issues and increased risk of flooding.
Monitoring the water level over four years below the urban area, we observed a gradual increase in the water level. However, if we left the scenario running for at least ten years, we could potentially reach the groundwater table. It is important to note that groundwater recharge occurs when water flows down from the surface and seeps into the ground, while groundwater discharge occurs when water flows out of the ground and to the surface.
In conclusion, our experiment provides insights into the importance of sediment types when it comes to water well construction. We saw that a layer with high permeability and porosity allows for more efficient water filtration, while a layer with low permeability and porosity poses a challenge in water flow. We also learned about the implications of urbanization on water drainage and the potential long-term effects on groundwater levels.
