  2. 2. Presentation On Jamuna River Erosional Hazards and Rural Vulnerability in Bangladesh: A Case Study on Sirajgonj District
  3. 3. Introduction Importance of river • Water is the most important natural resources for planet earth • The prosperity of nation depends primarily upon the exploitation of this resource. • Primary wealth of nation is water which flow in the river.
