GROUNDWATER Acquifers

* ____ > frozen soil * _____(____) > largest, deepest, and oldest lake in the world. * _____> smaller version of river basin * _____ > made up of several water sheds

Permafrost Lake Baikal (Siberia) Watershed River basin

- or ______ - natural pathway: solid>liq>gas - (ECPI) Evaporation>Condensation>Precipitation> Infiltration (Into the soil, surface runoff, and groundwater discharge)

HYDROLOGIC CYCLE or Water Cycle

READ ❤️ * Evaporation: warm air temp broad by sun causes water change to water vapor * Water vapour reach higher altitude (temp is cooler) and undergoes... * Condensation: transform larger droplets/accumulates cloud/fog * When droplets become heavy, it falls as... * Precipitation: form rain, hail, snOw * Replenishing water back into the oceans, lakes, river basins, and groundwater

WATERSHED FUNCTIONS 3 processes: CSR

1. Water Collection 2. Water Storage 3. Water Release

READ❤️❤️ Conservation & Protection of Water Resources • Control of human water consumption

read

- Rooflike water collection (directed to a storage: tank, cistern, deep pit; well shaft, or boreholes)

RAINWATER HARVESTING:

- Directly to surface water supplies (potable water, rainwater, river water: bed/body of rock stores groundwater) - Water for emergency uses

AQUIFER STORAGE & RECOVERY:

- Human-made conveyance add to aquifer (infiltration basins, trenches, dans, injection wells)

GROUNDWATER RECHARGE:

- Water from bathroom sinks, showers, tubs, washing machines - Contain dirt, grease, hair, cleaning products - "Dirty" but safe use for irrigation water

GREYWATER:

- Eliminating contaminants from municipal wastewater

SEWAGE WATER TREATMENT

- Use of water from 2 dif sources (ground/surface) to maximize sufficient yield. - Increase water sup/control undesirable instabilities

CONJUNCTIVE USE:

- Produce freshwater (Removes unwanted salt content in saltwater)

THERMAL DESALINATION:

WATER MANAGMENT METHODS (RAGG-SCT)

1. Rainwater Harvesting 2. Acquifer Storage & Recovery 3. Groundwater Recharge 4. Greywater 5. Sewage Water Treatment 6. Conjunctive Use 7. Thermal Desalination
