what are steady and unsteady flow of water what type of flow is assume is occur in soil
Answers
Answer:A steady flow is one in which the conditions of velocity, pressure, and cross–section may differ from point to point but do not change with time. If at any point in the fluid, the conditions change with time, the flow is described as unsteady.
Explanation:
Answer:
A major division in the types of flow of water in soil is that between saturated flow and unsaturated flow.
Upward flow of water may occur in a soil profile because of tan spiration by vegetation and evaporation from the soil surface.
Saturated flow occurs when the soil pores are completely filled with water. This water moves at water potentials larger than – 33 kPa. Saturated flow is water flow caused by gravity's pull. It begins with infiltration, which is water movement into soil when rain or irrigation water is on the soil surface.
