Fluvial Geomorphology

Study of the formation and function of rivers and their impact on the landscape.

Hydrology: The study of water movement, including precipitation, evaporation, infiltration, runoff, and streamflow.
Sedimentology: The study of sediment transport, erosion, and deposition in rivers and streams.
Geology: The study of the earth's physical structure, composition, and history; important in understanding the formation and behavior of river systems.
Ecology: The study of how living organisms interact with each other and their environment, including the role of plants and animals in river ecosystems.
Geomorphology: The study of landforms and the processes that shape them, including erosion, weathering, and tectonic activity.
Topography: The physical features of an area, including elevation, slope, and aspect, which can influence the behavior of rivers and streams.
Channel morphology: The physical shape and characteristics of a river channel, including its width, depth, and sinuosity.
River hydrodynamics: The study of fluid flow and turbulence in rivers, including the role of boundary layers, eddies, and turbulence.
River restoration: The practice of returning degraded or destroyed river systems to a more natural state, often through the use of engineering techniques.
Watershed management: The management of the land and water resources within a river basin, including land use planning, pollution control, and natural resource conservation.
River channels: River channels are the most prominent and widely studied feature of fluvial geomorphology. These channels can assume various forms such as straight, meandering, braided, anastomosing, wandering, and incised.
Floodplains: Floodplains are flat land areas that are adjacent to rivers or streams and are covered with water during flooding events. These areas are critical habitats for aquatic organisms and serve as fertile agricultural land.
Riparian zones: Riparian zones are the transitional zones between aquatic and terrestrial ecosystems. These areas are characterized by different vegetation types that influence the water quality, bank stability, and habitat suitability for different animals.
Alluvial fans: Alluvial fans are landforms that develop at the base of mountainous regions where streams and rivers transfer sediment to the valley floor. These landforms are characterized by their fan-like shape and the presence of a braided stream channel.
Delta plains: A delta plain is an area of sediment deposition that forms where a river empties into an ocean, sea, or lake. They are characterized by their triangular shape, bird's foot deltas, and distributary channels.
Fluvial terraces: Fluvial terraces are flat-topped landforms that are elevated above the active channel. They form when a river cuts down through its bed over time, leaving behind remnants of their former channel.
Oxbow lakes: Oxbow lakes are a crescent-shaped water body that forms when a meander neck of a river is cut off from the main channel as part of the natural fluvial process.
Braided rivers: Braided rivers are streams or rivers characterized by multiple, interconnected channels with sandbars and islands in between. They are common in areas with high sediment loads and fluctuating water levels.
Canyons: Canyons are narrow valleys with steep sides that are formed by erosion processes such as water, wind or ice. They can form in sedimentary, metamorphic or igneous rocks.
Gorges: A gorge is a steep-sided, narrow valley with dramatic cliffs that are usually created by the erosive action of a river or stream over a long time.
Waterfalls: A waterfall is a sudden drop or step in the elevation of a river or stream as it flows over a steep rocky slope.
Estuaries: An estuary is a coastal body of water where freshwater from rivers and streams mixes with saltwater from the ocean. They are critical habitats for several marine and aquatic species.
