Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	saturated and the slope is steep
B	saturated and the slope is gentle
C	unsaturated and the slope is steep
D	unsaturated and the slope is gentle

Explanation:

Detailed explanation-1: -Sandy soil will generally produce the least surface runoff. Soil texture information can assist with anticipating potential water storage and runoff. Keep in mind, of course, that it is still important to consider specifics of the situation such as soil moisture content and the rate of rainfall or snowmelt.

Detailed explanation-2: -When rainfall is greater than soil infiltration rate, surface runoff occurs. Factors affecting runoff include rainfall intensity, slope, soil water storage capacity, and infiltration rate [12].

Detailed explanation-3: -In addition to increasing imperviousness, removal of vegetation and soil, grading the land surface, and constructing drainage networks increase runoff volumes and shorten runoff time into streams from rainfall and snowmelt.
