Groundwater: Take a Glance
About this Course
This course introduces an overview of groundwater, principles of utilization, subsurface investigation, water table, water flow, and its movement, water well, and groundwater characteristics. The application of the theoretical in groundwater formulation and production will also be discussed.
Objectives
- To define the origin of groundwater from the general view of the water source.
- To describe groundwater characteristics at different areas or sources.
- To explain the alternative solution for groundwater demands from a national perspective
Learning Outcomes:
After completing the course you should be able to:
- Describe the overview of groundwater and its characteristic as an alternative water source.
- Apply the knowledge in groundwater application and practice for engineering purposes and daily use.
A warming welcome and lots of good wishes to this growing course.

LESSON 1 - GROUNDWATER
What is groundwater?
Groundwater is water that exists underground in saturated zones beneath the land surface. It found underground in the cracks and spaces in soil, sand and rock. Water that has infiltrated the ground to fill the spaces between sediments and cracks in rock.
Some part of the precipitation that lands on the ground surface infiltrates into the subsurface to replenish streams, rivers, and lakes. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
LESSON 2 - WATER TABLE
Where is the water table located on the earth?
The water table is the boundary between the unsaturated zone and the saturated zone underground. The upper surface of the saturated zone is called the water table. Water table also called groundwater table.
Below the water table, groundwater fills any spaces between sediments and within rock. It means that upper level of an underground surface in which the soil or rocks are permanently saturated with water.
The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it. The water table fluctuation both with the seasons and from year to year because it is affected by climatic variations and by the amount of precipitation used by vegetation. It also is affected by withdrawing excessive amounts of water from wells or by recharging them artificially.
