May I know the objective of this question? On a river basin scale one can understand the importance, but on a Global Scale why?

You can start by looking here:

Dear Prasad Sir,

Since We are working on global rivers and its relationship with public health we are looking for the amount of sediment supply from the river basins. Thanks.

Dear Samyadeep Sir,

Thanks for the link. I will explore this.

Thank you Dr. Rajasekaran for your response. Sorry for seeking another clarification. In what way amount of sediment supply is related to public health?

Hi Mangalaa!

Have a look at the section on "Modern terrestrial sediment supply" in the attached document. There you will find a recent summary with some diagrams and most of the relevant literature citations.
