Geog Field Trip around NJC!

Hellooo everyone!

Today we started learning about the hydrosphere, and how the drainage basin system (drainage basin hydrological cycle) works as a system, with flows, outputs, inputs and stores. (reminds me of our essay! haha)

Well we went around and had a mini field trip around the school and pictures are shown below. We learnt about how the saturation of the different kinds of soil (like say, with vegetation and without) have different zones of aeration in terms of size. In barren land, air gaps in zones of aeration are smaller, as the soil is being compacted. With this compaction, the gaps in the Earth cannot hold as much water as compared to those with vegetation, and thus surface runoff increases. This causes the water table to drop in it's level.

When zone of saturation increases in size, the water table will be raised, and those causes flooding.

Here the water is being collected by the drainage system.

Surface runoff from the canvas sheet!

Raining raining.

Here what's happening is the water is being collected as 1) the land cannot take in anymore (reached it's maximum point of saturation) and 2) the drain is higher than the ground level. So water is collected and does not flow into the drain as quickly.

yay. haha here's a video on serious surface runoff.

QUESTION OF THE LESSON: How do urban settlements affect the hydrological cycle?
