The drainage basin system is a crucial component of the water cycle, encompassing the area drained by a river and its tributaries. This system involves various processes including inputs, stores, transfers, and outputs of water. Rivers play a vital role in shaping landscapes and are subject to erosion, transportation, and deposition processes. Human activities and natural factors can contribute to flooding, necessitating various management strategies.

River erosion transportation processes play a crucial role in shaping landscapes and moving sediment through the drainage basin system. Understanding these processes is essential for studying river systems and their impacts on the environment.
River erosion processes include:
Example: Waterfalls are formed through the process of erosion, particularly undercutting, which creates a plunge pool. As the overhanging rock collapses, the waterfall retreats, forming a gorge-like valley.
4 types of transportation in a river include:
Vocabulary: Saltation refers to the bouncing of rocks along the river bed.
River features formed by erosion and deposition processes:
Highlight: The formation of these features demonstrates the dynamic nature of river systems and their ability to shape landscapes over time.

The drainage basin system is an integral part of the water cycle, encompassing the area drained by a river and its tributaries. This system involves complex interactions between various components of the hydrological cycle.
Key elements of the drainage basin system include:
Vocabulary: Evapotranspiration is the process by which water is transferred from land to the atmosphere through evaporation from surfaces (e.g., lakes) and transpiration from plants.
Drainage basin system water cycle diagram components:
Highlight: 97% of Earth's water is stored in seas and oceans, while only 0.3% is fresh water on the surface as part of the drainage basin system.
Key features of a drainage basin system water cycle map include:
Rivers can be divided into upper, middle, and lower courses, each with distinct characteristics in terms of gradient, load (sediment carried), discharge (amount of water passing a point at a given time), and river energy.
Definition: Gradient refers to the slope over which the river loses height.
