  1. Water Beneath the Surface By: Melbert Tabada Jumawan Jr.

  2. Where does the water of rivers and lakes came from? Is it possible that rocks can be a good storage of water?

  3. Groundwater

  4. Distribution and Movement of Water Underground Belt of Soil Moisture Intermediate Belt

  5. Water Table

  6. Water Beneath the Surface Two factors that affect the distribution and movement of groundwater 1. Porosity 2. Permeability - Aquifers - Aquitards e.g. clay

  7. Water Beneath the Surface Classification of groundwater aquifers • Unconfined aquifer system

  8. Water Beneath the Surface Classification of groundwater aquifers Confined aquifer system

  9. what factors influence how groundwater is stored inaquifers? Factors controlling natural recharge: • a. amount of moisture used by vegetation • b. nature of precipitation event • c. presence of subsurface barriers • d. amount of groundwater used by humans

  10. Water Beneath the Surface  Spring Natural Resources of Water

  11. Water Beneath the Surface Natural Resources of Water • Hot Springs Jigokudani hotspring in Nagano Japan

  12. Water Beneath the Surface Natural Use of Groundwater •  Geysers Strokkur, Iceland

  13. Geyser Eruption Cycle

  14. Water Beneath the Surface • Artesian Well • Artesian Spring

  15. Artesian Well

  16. Water Beneath the Surface Wells • A well is a • hole bored into • the zone of • saturation.

  17. Excessive pumping of wells Cone of Depression

  18. Dissolving of Groundwater Creates Caves and Caverns Caves

  19. Cavern

  20. Cave

  21. Geologic Activity of Groundwater  Travertine

  22. Water Beneath the Surface Caverns  Characteristics of features found within caverns 1. stalactites 2. stalagmites 3. columns

  23. Geologic Activity of Groundwater

  24. Water Beneath the Surface Karst Topography  Irregular topography  Common features • Sinkholes—surface depressions

  25. Examples of Karst Topography Limestone pavement in Dent de Crolles, France El Torcal (Antequera - Spain)

  26. Sinkhole Formation

  27. Examples of Sinkholes A special type of sinkhole – formed by rainwater leaking through the pavement and carrying dirt into a ruptured sewer pipe. Alapaha River, Florida

  28. What are the potentialproblems related to groundwater distribution and use?

  29. Water Beneath the Surface Environmental Problems Associated with Groundwater  Overuse and contamination threatens groundwater supplies in some areas. •1.Treating it as a nonrenewable resource • 2.Land subsidence caused by its withdrawal • 3.Contamination • 4.Salt water intrusion

  30. Land Subsidence

  31. Groundwater Contamination

  32. Saltwater Intrusion
