The Jalaparijnanam is in paper book form. Moreover it is in Malayalam script.
Let me see whether I can create a version in Devanagari script with English translation.
Still let us know, whether you are successful with the knowledge.
The book was published by Panchangam Pustaka Shala at Kunnamkulam, Thrissur (website kanippayyur.in). The Malayalam commentary was by Kanippayyur Sankaran Namboodiripad. The Kanippayyur family is famous for their knowledge and promotion of the Indian sastras of Jyotisha, Vastu, Ayurveda.
We had dug a well after taking the advice of Kanippayyur Krishnan Namboodiripad few years back. It was a conventional well and water was found. Now I realize that there indeed is a Jamun tree to the south of the well!
Another clarification from the book is that a “persons height” is with his arms held up, not upto the top of the head as normally done. So the “persons height” is around 2.4 meters.
