Surface Runoff Notes

About this Chapter

This document contains the complete study material for Chapter 4: Surface Runoff. Surface runoff represents the portion of precipitation that makes its way towards rivers or oceans as surface or subsurface flow.

In this chapter, students will learn the factors affecting runoff, characteristics of rivers, rainfall-runoff relations, and regional formulae like MIP, WECS, and MHSP methods for estimating monthly flows.
