River TerracesOver time, rivers may change their course or base level, leaving behind remnants of old floodplains elevated above the current river level. These elevated flat areas are known as river terraces. |
Meanders are sinuous, looping bends or curves in the middle and lower reaches of rivers. This occurs when the river erodes its banks unevenly, causing it to curve and form meanders. Meanders are dynamic features that continuously evolve and change over time due to the interaction of water flow, sediment transport, and the surrounding landscape. Meandering rivers are ecologically valuable as they create diverse habitats and provide important ecological niches for various species of plants and animals. Additionally, meanders play a crucial role in sediment transport and nutrient cycling within river ecosystems. They also influence human activities, such as agriculture and urban development, as meanders can affect the risk of flooding and the stability of riverbanks.
