During the rainy season, a black mud flows in the Dahare River. Many people understand the black mud flowing in this river in the Rudrabeni-Bami section of Satyawati Rural Municipality-6 as Barkhe Bhel. However, a study has confirmed that it is from an 'active rift'.

The black lodo flowing in the Angar Khola (Dahare Khola) is due to an ‘active crack’, said Dr. Kaviraj Paudyal, an associate professor at Tribhuvan University Kirtipur and currently the co-controller of examinations. This has been confirmed by a recent study. ‘The black lodo flowing is not a barkhed bhela, it is flowing after the ground has moved due to a mountain crack,’ he said. ‘This is called an active crack in geological terms, which can become the epicenter of small earthquakes and a source of devastating earthquakes.’

He said that the study showed that the landslides between Angar Khola and Lumdi Khola were due to an active crack. He said that the crack in Nadeva Khola and the landslides caused by it were also observed.

This study was conducted under the research project Nepal Pine, conducted under the Central Department of Hydrology and Meteorology, Kirtipur, in agreement between Tribhuvan University Campus Kirtipur and Lausanne University Campus Switzerland. Which was measured in the Rudrabeni-Ullikhola area of ​​this area . Geologically, the term 'active crack' is called 'Wadigad Active Fallbat' .

Active crack means a condition where the ground cracks and separated pieces of land become mobile . Due to which, research has confirmed that it can be the epicenter of small earthquakes and can also become a source of destructive earthquakes in the future, said Gaurav Gyawali, another young geologist involved in the research .

Geologist Dr. Kaviraj Paudyal said that infrastructure construction such as roads, hydropower and tunnels in this place where there is an active crack should be done only after understanding the condition of the crack . He said that attention should be paid to potential disaster reduction and public awareness should be created .

For which, for research based on data, temperature and rainfall measurements have been kept at Satyawati Secondary School under the meteorological instrument and geological educational materials have been studied and handed over , said Paudyal. He said that it would be easier to understand the overall situation with the measuring device. Along with Paudyal and Gyawali, hydrology and meteorology expert Dr. Binod Dawadi and sociologist and anthropologist Dr. Jeevan Paudyal are also involved in this study.

The climate measurement center set up at Satyawati Secondary School is expected to provide all kinds of information related to this. It will also study landslides and other risks around the Wadigad River in the Rudrabeni-Bami section to some extent. 60 students and 20 teachers of the school were also given an active contract site observation by setting up the measurement center.

This part of Gulmi is located in the Mahabharata mountain range under the Himalayan mountain range, and a presentation was made among the students by making wooden models related to the birth, development and cracks of this structure. In addition, the rocks, landslides, minerals, and geological models found in Satyavati and the surrounding areas were shown to the students about the origin of the Himalayas, the process of formation of rocks and minerals, the causes of landslides, and preventive measures.
