How to check slope of your agri land?

In order for you to plan for water harvesting,you need to know lowest point in your land and slope direction of your land to layout water channel.

  • One way is to engage civil engineer to do contour survey but most of the time you won’t get techie people in village.
  • Another way is to walk up to your field right at the moment of intense rainfall to see where water is heading to?
  • Yet another way is to check water logging spots after rainfall but it won’t tell you how to plan feeding channels

Never worry. You can be a civil engineer and plan yourself from anywhere in the world (With Google pro free trial membership for 7 days)

The ancient ingenuity of water harvesting

Very inspiring TED talk on water harvesting. In this talk Mishra explores and expounds on the various ways that indigenous Indians harvest water with wells, filter ponds and catchment systems in Golden dessert of Rajastan which only receives 9 inches of rainfall.  It’s possible to get water from just about anywhere, and that’s reassuring!
