1. Describe how precipitation intensity might affect the flow of surface water

Jawaban:

1. Precipitation is a determining factor of surface flow, and it is directly related, which means if precipitation is high in magnitude, the surface flow will increase also. Nevertheless, there is still another minor factor that could affect the surface flow.  (4 marks)

2. A hydrograph is a useful tool that is made by the combination of mathematical values. These values are further processed to create useful information such as lag time, precipitation rate, infiltration rate, peak discharge, and so much more. On studying the catchment area, this stated information can be useful for prediction. Much other functionality may be possessed in the use of hydrograph. (8 marks)
