Acceleration is the rate of change of velocity - in symbols, a = dv/dt. Or for average acceleration over a finite time: a(average) = delta v / delta twhere delta v is the change in velocity, and delta t is the time interval.
As a river flows it picks up sediment and carries it away. When the river reaches the ocean the sediments deposited, over time a delta forms.
delta
The answer depends on the context. Delta is a letter of the Greek alphabet and is shaped like a triangle. Mouths of rivers, which are often triangular in shape are, therefore, also called deltas. In mathematics, delta is often used to denote a change, particularly a small change. There is also the Dirac delta function which is an asymptotic spike function and is used in quantum physics.
Deltas of any rivers will alter over time. A channel may silt up and become blocked, so forcing the water to form a new channel elsewhere - a continuous process.

Deltas are landforms formed at the mouth of a river where the river meets a body of water, such as a sea or ocean. Silt is a type of sediment that is commonly found in river deltas, as it is carried by the river and deposited in the delta. The accumulation of silt over time contributes to the growth and formation of delta landforms.
Acceleration is calculated using the formula ( a = \frac{\Delta v}{\Delta t} ), where ( a ) is acceleration, ( \Delta v ) is the change in velocity, and ( \Delta t ) is the change in time. To compute it, subtract the initial velocity from the final velocity to find ( \Delta v ), then divide that value by the time interval ( \Delta t ) over which the change occurs. The resulting value will be in units of velocity per time, such as meters per second squared (m/s²).
Delta is typically used to symbolize "change in" a definable quantity; e.g., "delta t" could symbolize "change in time", where t means time. Since delta, used this way, is really a math term, such as capital sigma is the "sum as" term, then used this way, no it does not change. However, if you are using delta as a variable, the way that you can use any symbol as a variable, then yes, it can change. In geology a delta is constantly changed by the action of the sea and the water diversion from human industry/deforestation, and rubbish being washed down stream
The mathematical formula for calculating average acceleration is given by: [ a_{\text{avg}} = \frac{\Delta v}{\Delta t} ] where ( a_{\text{avg}} ) is the average acceleration, ( \Delta v ) is the change in velocity, and ( \Delta t ) is the change in time over which the acceleration occurs. This formula represents the ratio of the change in velocity to the time interval during which that change occurs.
A delta is built up by sediment transported by a river and deposited at its mouth where the river meets a body of standing water, such as a lake or ocean. Over time, these deposits accumulate and form a triangular or fan-shaped landform.
A delta is a triangular-shaped sediment accumulation at the mouth of a river where it meets a body of water, such as an ocean or lake. As the river's flow slows down upon entering the larger body of water, it deposits sediment it has been carrying, creating the delta over time.
