Question

what are the factors that affect seepage and run off​

Answer 1

Explanation:

Meteorological factors affecting runoff:

• Type of precipitation (rain, snow, sleet, etc.)
• Rainfall intensity.
• Rainfall amount.
• Rainfall duration.
• Distribution of rainfall over the watersheds.
• Direction of storm movement.
• Antecedent precipitation and resulting soil moisture.

Answer 2

Explanation:

Seepage

Seepage is the process in which fluid moves slowly through the small openings or cracks in the surface of unsaturated soil. The fluid fills the pores or cracks in the unsaturated bottom layer and then moves into the deeper layers as a result of the effect of gravity.

Factors affecting seepage

Factors that are responsible for affecting the seepage flow are as follows.

• Soil porosity
• Permeability
• Infiltration capacity
• Precipitation Intensity
• Hydraulic Conductivity
• Hydrostatic Pressure
• Weak interlayers of geologic formations

Runoff

Runoff is the draining or flowing off of precipitation from a catchment area through a surface channel which enters into a stream channel.

Factors affecting runoff

Factors that are responsible for affecting the runoff are as follows.

• Precipitation characteristics
• Shape and size of catchment
• Topography
• Geologic characteristics
• Storage characteristics of a catchment
• Meteorological characteristics
