    News In Short – 2 September, 2025

    Context

  • The India Meteorological Department (IMD) has warned of heavy to extremely heavy rainfall across North India due to an unusual weather phenomenon termed “2-System Interaction.”

    • Why is it Significant?

  • Geographical Vulnerability: The Himalayan terrain is steep, fragile, and densely populated in valleys, making it highly prone to landslides and flash floods.
  • Climatic Shift: Such interactions, once occasional, are being reported more frequently due to changing monsoon dynamics and rising global temperatures.
  • Hydrological Impact: Sudden surges in rainfall increase risks for rivers and reservoirs, threatening infrastructure and communities downstream.

  • The Immigration and Foreigners Act, 2025 comes into effect bringing a comprehensive overhaul of India’s immigration and foreigner management regime.

  • Immigration: The Act provides that persons entering or departing from India must also have a valid visa (for foreigners) along with valid passports or other valid travel documents.  These documents may be examined by the immigration officer.

    Why Some Rivers Stay Single While Others Split?

    Context

  • Researchers at the University of California, analysed 36 years of satellite data across 84 rivers worldwide to identify why some rivers maintain a single-thread channel, while others develop into braided or multi-thread systems.

    • Fluvial Processes and Channel Types

  • Rivers are broadly classified as single-thread or multi-thread (braided/ anastomosing). 
  • In a single-thread river, lateral erosion of one bank is roughly matched by sediment deposition on the opposite bank.
  • This balance keeps the channel width constant and lets the river meander across its floodplain.
  • Multi-threaded rivers occur where bank erosion exceeds deposition.
