Study Notes
Hydrogeology Overview
- Hydrogeology is the study of groundwater occurrence, movement, and chemistry within geological environments.
- Key aspects include the hydrogeological cycle, classification of aquifers, and groundwater management.
Course Structure
- Course consists of 28 hours of lectures and 28 hours of practical work, totaling 4 ECTS credits.
- Assessment format includes 60% written exam, 30% practicum, and 10% group presentation.
Course Goals
- Understand the hydrogeological cycle concept.
- Identify and classify groundwater occurrences.
- Calculate simple groundwater balances.
- Gain basic knowledge of groundwater in Suriname.
Key Topics Covered
- Hydro(geo)logical cycle includes precipitation, evaporation, infiltration, and surface runoff.
- Groundwater chemistry and management techniques.
- Specific focus on groundwater in Suriname.
Precipitation Process
- Precipitation refers to any form of water that falls from the atmosphere, including rain, snow, sleet, and hail.
- It connects the water cycle, transporting moisture from atmosphere to earth.
Evapotranspiration
- Evapotranspiration is the sum of evaporation from land surfaces and transpiration by plants.
- Influenced by meteorological conditions like temperature, humidity, and wind.
Infiltration and Surface Runoff
- Infiltration is the process where precipitation enters the unsaturated zone and is crucial for groundwater recharge and irrigation.
- Surface runoff occurs when excess water flows over land, contributing to lakes and rivers.
Groundwater Systems
- Groundwater systems exist in zones where rock cavities are filled with water under pressure.
- Groundwater tables fluctuate based on seasonal changes and local conditions.
Groundwater Recharge and Discharge
- Recharge includes processes where water enters groundwater systems, primarily from precipitation and surface water.
- Discharge refers to the outflow of water from groundwater systems, occurring through springs and abstractions.
Measurement Techniques
- Precipitation data is collected using rain gauges and automatic recorders.
- Infiltration rates and evapotranspiration are assessed through various methods including evaporation pans and lysimeters.
Surface Water Systems
- Surface water bodies are categorized as perennial, ephemeral, or manmade, each with distinct hydrological characteristics.
- Monitoring surface water involves measuring discharge, which is the volume of water flowing through a specified area over time.
Group Presentation Project
- Groups will conduct a presentation on an aquifer covering aspects like location, classification, porosity, recharge sources, and usage rates. All sources must be cited.
Important Concepts in Hydrogeology
- Hydrogeological cycle components: precipitation, evaporation, infiltration, surface runoff.
- Water balance calculations, groundwater management strategies, and the interplay between surface and groundwater systems.
