Forms of the Flow of Running Water as the Geomorphic Agent:

1. Laminar Flow:
Laminar flow is a type of flow where water moves in a smooth and orderly manner. It occurs when water flows in layers, with each layer moving at a different speed. This form of flow is characterized by a slow and steady movement of water, with minimal turbulence. Laminar flow is typically observed in calm and shallow water bodies, such as small streams and rivers.

Key Points:
- In laminar flow, water particles move parallel to each other in a straight line, without crossing or mixing with adjacent layers.
- The flow is characterized by the absence of turbulence, resulting in a smooth and tranquil movement of water.
- Laminar flow is influenced by factors such as water viscosity, channel slope, and channel roughness.
- It is more likely to occur in low-gradient channels, where the water velocity is relatively low.
- Laminar flow is responsible for the erosion and transportation of fine particles, such as silt and clay, as they are easily carried by the gentle movement of water.

2. Turbulent Flow:
Turbulent flow is a type of flow where water moves in an irregular and chaotic manner. It occurs when water flows at a high velocity or encounters obstacles or irregularities in its path. This form of flow is characterized by the mixing of water particles, resulting in eddies, whirlpools, and waves. Turbulent flow is commonly observed in fast-flowing rivers, waterfalls, and rapids.

Key Points:
- In turbulent flow, water particles move in a random and chaotic manner, with swirling and eddying motions.
- The flow is characterized by the presence of turbulence, which is caused by the interaction between different layers of water moving at different speeds.
- Turbulent flow is influenced by factors such as water velocity, channel slope, channel roughness, and the presence of obstacles in the channel.
- It is more likely to occur in high-gradient channels, where the water velocity is relatively high.
- Turbulent flow is responsible for the erosion and transportation of coarser particles, such as sand and gravel, as they are easily dislodged and carried by the turbulent motion of water.

In conclusion, the flow of running water can occur in two forms: laminar flow and turbulent flow. Laminar flow is characterized by a smooth and orderly movement of water, while turbulent flow is characterized by an irregular and chaotic movement. Both forms of flow play a significant role in shaping the Earth's surface through erosion, transportation, and deposition of sediment.
