Presentation Transcript

  1. Introduction to Hydrogeology (Module 1) Hydrogeology Course for Museum Studies and Conservation Lecturer: Dr. Erkin Khaltursunov

  2. Overview of Hydrogeology • Hydrogeology studies the distribution and movement of groundwater in the Earth's crust. • Groundwater plays a critical role in providing water for drinking, agriculture, and industrial use. • Hydrogeology also contributes to environmental sustainability and conservation.

  3. Historical Background • Hydrogeology has evolved over centuries. • Key historical figures: Henry Darcy (Darcy's Law), Theodor Rehbock (groundwater models). • Modern hydrogeology integrates technology, GIS, and remote sensing.

  4. Water Cycle and Hydrogeology • The water cycle: Evaporation, Precipitation, Infiltration, Runoff. • Groundwater forms an integral part of the hydrological cycle. • Infiltration of precipitation feeds underground aquifers.

  5. Groundwater Basics • Groundwater: water stored in porous rock and sediment below the surface. • Groundwater reservoirs are crucial for water supply in many regions. • Subsurface water includes both shallow aquifers and deeper groundwater layers.

  6. Aquifers • An aquifer is a geological formation that stores water. • Types: Unconfined aquifers (open to the surface), Confined aquifers (trapped between impermeable layers). • Porosity and permeability determine an aquifer's water storage capacity.

  7. Groundwater Flow • Groundwater flows through aquifers driven by gravity and pressure. • Darcy's Law explains the flow rate based on permeability and pressure gradient. • Groundwater flow helps recharge surface water bodies and wetlands.

  8. Hydraulic Conductivity • Hydraulic conductivity: a measure of a material's capacity to transmit water. • High conductivity materials (sand, gravel) facilitate faster flow; low conductivity materials (clay) slow flow. • It impacts groundwater availability and pollution spread.

  9. Porosity and Permeability • Porosity: The proportion of void space in a material. • Permeability: The ability of a material to transmit fluids through it. • Both influence groundwater storage and movement.

  10. Groundwater Recharge and Discharge • Recharge: water enters the aquifer via precipitation or surface water. • Discharge: groundwater exits the aquifer to springs, rivers, or oceans. • Human activities can alter recharge and discharge rates.

  11. Module 1: Introduction to Hydrogeology Museum Studies, Conservation, Repair, and Preservation of Historical and Cultural Objects

  12. What is Hydrogeology? • Hydrogeology is the study of groundwater, including its occurrence, movement, and properties. • • Focuses on the interaction between groundwater and surrounding soil or rock. • • Essential for managing water resources and addressing water-related issues.

  13. The Importance of Hydrogeology • Understanding groundwater is crucial for: • • Water supply management • • Agricultural irrigation • • Conservation of historical and cultural objects • • Mitigating groundwater pollution and contamination

  14. Groundwater in Cultural Preservation • Groundwater impacts heritage conservation by: • • Affecting the structural stability of historical buildings • • Contributing to material degradation • • Influencing the preservation environment for artifacts

  15. The Hydrological Cycle • The hydrological cycle describes the continuous movement of water on, above, and below the Earth’s surface. • • Includes evaporation, condensation, precipitation, and groundwater recharge. • • Groundwater plays a key role in maintaining the balance of the cycle.

  16. Groundwater Recharge • Groundwater recharge is the process by which water from precipitation and surface water infiltrates the ground and replenishes aquifers. • • Critical for maintaining groundwater levels • • Recharge rates vary depending on soil, rock types, and climate conditions.
