Factors Affecting Effective Rainfall

1. Rainfall characteristics:-

i) High intensity of rainfall - less effective rainfall
ii) More duration of rainfall - less effective rainfall
iii) Well distributed rainfall - more effective rainfall
iv) With light showers.

2. Land characteristics:-

i) Leveled land - more effective rainfall
ii) Sloppy land - less effective rainfall more runoff
iii) Ploughed land - More effective rainfall
iv) Vegetative cover - Less runoff, more effective rainfall.

3. Soil characteristics:-

i) Infiltration rate - high infiltration rate - more effective rainfall
ii) Storage capacity - More storage capacity - more effective rainfall
(Depth of soil)
iii) Initial water content - high initial water content then less will be the effective rainfall

        

4. Crop characteristics:-

More roof zone depth complete ground cover Active stage of growth - More uptake of water more will be effective rainfall. 

                    

5. Climate:

More radition    High temperature and Low temperature Relative humidity – High crop requirement and more effective rainfall  

        

6. Vegetative cover:-

Surface condition of soil canopy soil cover natures of roots mulches etc. affects the effectiveness of rainfall.
