what surface ruoff is the water flow that occurs when the soil is infiltrated to full capacity and excess water from rain, meltwater, or other sources flows over the land.
steep slope, heavy rain, and frozen ground
If one of your choices is "cover the dirt road with pavement" or anything to help stop infiltration (as pavement stops rain from infitrating the dirt)...that is the one to choose.

Runoff is the result of rainfall.
1. Surface Runoff: It is that portion of rainfall which enters the stream immediately after the rainfall. It occurs. When all losses are satisfied and if rain is still continued, with the rate greater than in filtration rate; at this stage the excess water makes a head over the ground surface (surface detention) which tends to move from one place to another, known as overland flow. As soon as the overland flow joins to the streams, channels or oceans, termed as surface runoff.2. Sub - surface Runoff: That part of rainfall, which first leaches into the soil and moves laterally without joining the water - table to the Streams Rivers or oceans is known as sub - surface runoff. Sometimes sub - surface runoff is also aerated under service ninoff due to reason that it takes very title time to reach the river or channel in comparision to ground water. The sub - surface runoff is usually referred as interflow.3. Base flow: It is delays flow, defined as that part of rainfall which after talling on the ground surface in fill rated into the soil and meets so the water table and flow to the streams oceans etc. The movement of water in this type of runoff is very slow that is why it is also referred as delayed runoff. It takes a long time to join the rivers or oceans. Some times base flow is also known as ground water flow.

Runoff is the result of rainfall.
In areas where there is no snow, runoff will come from rainfall. However, not all rainfall will produce runoff because storage from soils can absorb light showers. Infiltration excess overland flow more commonly occurs in arid and semi-arid regions, where rainfall intensities are high and the soil infiltration capacity is reduced because of surface sealing, or in paved areas. When the soil is saturated and the depression storage filled, and rain continues to fall, the rainfall will immediately produce surface runoff. Urbanization increases surface runoff, by creating more impervious surfaces such as pavement and buildings, that do not allow percolation of the water down through the soil to the aquifier.

The surface run off is likely to be greatest on a sloped area (30 deg-45deg) where we have least forest cover or an area where deforestation has occurred during heavy rainfall. This sloped area could be of an hill or edging flanks of a plateau........
Yes, runoff is likely to increase as vegetation in the area decreases. Vegetation plays a crucial role in absorbing and slowing down rainfall, allowing water to infiltrate into the ground. Without vegetation, more water will run off the surface, leading to increased runoff. This can result in higher risks of flooding and erosion.
