12.3.1 Methods of Sediment Yield Determination
A huge amount of research effort has been spent on understanding and modeling the soil erosion process. Many scientific studies have been conducted on experimental watersheds to assess the effect of land use on soil loss. The land uses which have been studied include forests, grasslands, agricultural lands, fallow lands, ravine lands, bare lands, and horticultural lands.
Approaches ranging from empirical methods to detailed physical model have been used to predict reservoir sedimentation. The choice of a prediction method largely depends on the objectives of the study; it may vary in different stages (planning, feasibility study, design and operation). As such, there is no best method that can be used for all the river basins. Nowadays, mathematical modelling has become a widely used tool. These methods to determine sediment yield are briefly summarised in what follows.

Answer:
Fallow land is referred to the land that has been used for farming after which it is left uncultivated for a season, thereby allowing it to recover its fertility and productivity. It helps in replenishment of the lost nutrients in that area of the land.
Continuous farming on one piece of land degrades its fertility and this affects the productivity of the land. Hence, various techniques are employed such as crop rotation, alternative farming, etc. that keeps the yield consistent.
