How is lag time affected by distance?

The impact of an event happening at a distance takes some time to reach the observer. This is the lag time and, as the distance increases, the lag time increases. The increase depends on the velocity of transmission of the information. For example, the lag time for a flash of lightning depends on the speed of light; the lag time for the clap of thunder depends on the speed of sound; the lag time for the person that the lightning bolt missed depends on how fast they can run to you.

Differences hydrograph in rural and urban?

Rural hydrographs have a much longer lag time as the water that is needed to get to fill the river to its 'peak discharge' needs to go through the dense soil through the process of ground water flow and ground flow, to get into the river. This means that the rising limb of this hydrograph will be much longer than that of an urban area as it takes a longer time for the river to fill to its full capacity. The falling limbs will stay roughly the same. In contrast, the urban hydrographs will have a much quicker lag time as the water that is needed to fill the river up to its 'peak discharge' can access it much quicker and easier as more surface run-off occurs from the urban areas being built out of impermeable cement or concrete buildings and roads. Also, as the water is sitting on the impermeable surfaces, more evaporation will occur and in turn this will cause more precipitation to happen, making the process in an urban area even faster than that of a rural one.
