Study Notes
Drainage Basin
- An area of land where all precipitation gathers and drains off into a common outlet, such as a river or lake.
- Functions as a critical part of the hydrological cycle, influencing water flow and sediment transport.
Tributary
- A river or stream flowing into a larger river or lake, contributing to its water volume.
- Plays a key role in increasing the complexity of a river system and its ecological diversity.
Confluence
- The point where two or more bodies of water meet, such as where a tributary joins a main river.
- Significant for ecological habitats and water resource management.
Mouth
- The location where a river flows into a larger body of water, such as an ocean, sea, or lake.
- Essential for sediment deposition and often characterized by deltas or estuaries, rich in biodiversity.
Watershed
- An area of land that separates waters flowing to different rivers, lakes, or seas; also known as a catchment area.
- Essential for watershed management and conservation efforts to protect water resources.
Interception
- The process by which precipitation is caught and held by vegetation, leaf litter, and other surfaces before reaching the ground.
- Helps reduce soil erosion, improve water retention, and support biodiversity.
Infiltration
- The process of water entering the soil surface, becoming part of the groundwater supply.
- Influenced by soil composition, vegetation, and land use, affecting overall water availability.
Surface Run-off
- Water that flows over the ground surface when the soil is saturated or impermeable.
- Critical for generating river flow and influencing flood events.
Throughflow
- The lateral movement of water through the soil layer towards rivers and streams.
- Essential for maintaining stream ecosystems and influencing water quality.
Erosion
- The process of wearing away the Earth's surface by wind, water, ice, or human activity.
- Influences landscape formation, sediment transport, and ecosystem dynamics.
