Both heavy rain and runoff can cause floods.
When rain is heavy and land is inclined , it rolls into stream. It is known as runoff.
acid rain comes from chemicals in the clouds, not runoff there is no "car runoff" runoff is from the slanted ground into water bodies
Runoff is more likely after a heavy rainstorm because the soil becomes saturated quickly, preventing water from infiltrating into the ground. This excess water flows over the surface, picking up contaminants and pollutants before eventually entering nearby water bodies. Additionally, heavy rainstorms can cause flooding, which increases the volume and velocity of the runoff.
In a desert, the soil is often dry and compacted, which can lead to poor water absorption and increased runoff during heavy rain showers. This runoff can cause rapid erosion by carrying away loose sediment and creating gullies or channels in the landscape due to the lack of vegetation to hold the soil in place.
desert plateaus are made because of heavy rainfall. You may think that it doesn't rain in the desert, but it does. It doesn't rain very often but when it does it usually results in flash flooding. Because there is no runoff, the water causes erosion so there can be runoff. The erosion is what makes the plataeu.

A river turns muddy after heavy rain because the rain washes soil, sediment, and debris into the river, causing it to become turbid. The increased flow from the rain also stirs up sediment from the riverbed, further contributing to the muddy appearance of the water.
rain
runoff
Runoff from rain and runoff from melting snow (which is NOT the same as glacial runoff).
When rain rolls into a stream it is known as runoff.
