Question

Factors that affect runoff and the shape of a hydrograph for a stream include watershed slope, precipitation intensity and duration, antecedent moisture, land use, land cover, and the properties of the stream channel, several of which are related to human activities.

Select one:

True

False

Answer 1

Following factors affect runoff and shape of hydrograph.

1.Watershed slope-It is ridge line that separate two catchment areas. It is natural slope so not related to human activities.

2.Precipitation intensity and duration

Precipitation is natural phenomenon so not related to human activities.

3.antecedent moisture

It is the degree of moisture at the beggining of runoff. This factor affected by human activities.

4.Land use patterns

Land use for farming for kharif or rabbi crops affect the moisture of soil and it affect the runoff and shape of hydrograph so it is related to human activities.

5.Land cover

Land cover affected due to deforestation and aforestation and it is affected by human activities.

6.Properties of stream channel is depends on topograhy and other natural parameters so it is not related with human activities.
