Tectonic uplift and climate change are viewed as dominant mechanisms that can shape the earth’s surface through erosion. River terraces can be influenced by one or both of these forcing mechanisms and therefore can be used to study variation in tectonics, climate, and erosion, and how these processes interact.
River terrace, bench or step that extends along the side of a valley and represents a former level of the valley floor. A terrace results from any hydrological or climatic shift that causes renewed downcutting.
River Terraces: The narrow flat surfaces on either side of the valley floor are called river terraces which represent the level of former valley floors and the remnants of former (older) flood plains. Sometimes, the river valleys are frequented by several terraces on either side wherein they are arranged in step-like forms.
May 5, 2022 · River Terraces: River terraces are surfaces marking old valley floor or floodplain levels. They are basically products of erosion as they result due to vertical erosion by the stream into its own depositional floodplain.
River terraces are generally formed due to dissection of fluvial sediments of flood plains deposited along a valley floor. There are much variations in terraces as regards their morphology, structure and mode of origin. River terraces are classified in various ways.
Alluvial Terrace: Alluvial terraces are the sites of former floodplains which are deeply eroded by the stream due to its rejuvenation. Its process of formation is explained in the following stages.
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers".
River Terraces. River terraces are surfaces marking old valley floor or floodplain levels. They may be bedrock surfaces without any alluvial cover or alluvial terraces consisting of stream deposits. Paired terraces: The river terraces may occur at a similar elevation on either side of the rivers.
The term ‘river terrace’, according to Pazzaglia, was introduced in modern physical geography in the latter part of the 19th century. Pazzaglia has defined river terraces as ‘landforms underlain by alluvial deposits’.
