| Knowledge Attribution | Meandering rivers often carry nutrient-rich sediment, which can be deposited on the floodplain as the river meanders and changes course over time. This can create fertile soil that is ideal for agriculture and can support higher crop yields. In addition to providing nutrients, meandering rivers can also help to regulate water flow and prevent flooding in the surrounding area. | ||
| Description | The natural curves and bends in the river slow down the flow of water and allow it to spread out over a wider area. This can help to reduce the risk of flash floods and can provide a steady supply of water for crops during dry periods. Rabi crops yield increased along the Koshi floodplain due to new soil deposited by flood. The fertility of the soil has increased after the flood every year. | ||

Prior to the flood, the villagers create temporary shelters in a raised location to relocate their cattle and stockpile firewood and provisions
Flood in the village starts in June and stays up until September month that erodes arable land, destroys paddy crops, and also increases the amount of iron in the drinking water which increases the problem of disease. The villagers get indication and information from the nearby villages and prepare to relocate to the safer places. The tents made of plastic sheets and the bamboo prepared at the elevated area serve as the temporary shelters for both human and the castles. They transfer the livestock along with firewood and food prior to the flood. Flood water enters the local people’s houses which creates problem in the cooking of the foods inside the homes, so peoples have to travel by boat to the elevated places for survival.
The government tried to stop erosion by building embankmentst with the help of eucalyptus bats and sandbags
In India, embankments are commonly used to protect agricultural land and human settlements from river erosion and flooding. The use of eucalyptus bats and sandbags in building these embankments are considered an effective way to control erosion. Since eucalyptus is a readily available local material, its use in embankments is cost-effective and sustainable, also the wood is durable and resistant to decay. Similarly, sandbags are relatively inexpensive and can be quickly deployed in emergency situations. The construction of an embankment with the help of eucalyptus bats and sandbags is an effective method for controlling erosion in the area. It is a sustainable solution that can help protect the environment and promote long-term stability and resilience in communities that rely on natural resources. Therefore, the government has been also trying to control erosion with the help of eucalyptus bats and sand sacks.
