Brhat samhita discusses the ground water development and water quality methods. Driven by sound concepts, people of ancient Bharat could locate groundwater, analyze its distribution and had knowledge of reaching these water-tables to irrigate fields.

As food is the elixir of life to living beings, and as food is dependent on the monsoon, it should be investigated carefully. He explains the exceptional ability of predicting exact time of rainfall with the help of astrological sciences. A good astrologer who observes the skies and cloud formation, with the knowledge of planetary positions and [[Nakshatras (नक्षत्राणि)|nakshatras]] can accurately predict the rainfall according to Varahamihira. <blockquote>मार्गशिरःसितपक्षप्रतिपत्प्रभृति क्षपाकरेऽषाढाम् । पूर्वां वा समुपगते गर्भाणां लक्षणं ज्ञेयम् ।। २१.०६ ।। (Brhd.

Thus an astrologer starts observing the skies (for the formation of clouds) from that day of the bright half of Margasira month when moon transits Purvashada nakshatra. The cloud fetus so formed during the moon's stay in a particular asterism (nakshatra) will be delivered (in the sense of rainfall) 195 days (savana day) after the fetus formation, when the moon transits the same nakshatra (this usually falls in the months of Jyesta and Ashadha, the rainy seasons) as given in the shloka below. <blockquote>यन्नक्षत्रं उपगते गर्भश्चन्द्रे भवेत्स चन्द्रवशात् । पञ्चनवते दिनशते तत्रएव प्रसवं आयाति ।। २१.०७ ।। (Brhd.
