Attrition occurs by small pebbles rubbing against the rivers' bed or walls, and over the space of a few years it wears away.
Corrasion, Hydraulic action, Attrition
Three types of erosion that can affect a river valley are hydraulic action, abrasion, and attrition. Hydraulic action refers to the force of moving water eroding the river banks, abrasion is the process of rocks and sediment in the water wearing away the riverbed, and attrition occurs when rocks in the river collide, break down, and become smoother over time.
Attrition occurs when employees leave an organization, either voluntarily or involuntarily, leading to a decrease in the workforce. It can happen for various reasons such as job dissatisfaction, lack of growth opportunities, or organizational changes. High attrition rates can impact a company's productivity and morale.

Annual attrition is the actual attrition rate for a year or a period of years. Annualized attrition would be an extrapolation based on the portion of a year (for example, take the actual attrition for 6 months and double it to arrive at an annualized attrition rate).
The main types of erosion that occur in rivers are hydraulic action, abrasion, attrition, and solution. Hydraulic action is the force of the water itself wearing away at the river banks, while abrasion is the process of rocks and sediment carried in the water rubbing against the river bed and banks, wearing them down. Attrition is when rocks and sediment in the water collide with each other, causing them to break and become smoother. Solution occurs when certain rocks or minerals dissolve in the water, contributing to erosion.

The three ways of river erosion are hydraulic action (force of water on the river banks), abrasion (wearing down of the riverbed by sediment), and attrition (erosion caused by rocks and sediment carried by the river rubbing against each other).
