33. The railway network in India is divided into

The railway network in India is divided into

8 zones.
10 zones.
17 zones.
20 zones.
This question was previously asked in
UPSC CISF-AC-EXE – 2020
The railway network in India is divided into administrative zones. While the number has changed slightly over time, 17 zones was the established number for a significant period and is typically referred to in many contexts. As of recent updates, the number is 18. However, given the options, 17 is the most appropriate answer reflecting the standard structure known for a long time.
Indian Railways is organized into functional zones for efficient administration and operation of the vast railway network.
The 17 zones (before the 18th was created in 2019) included Central, Eastern, East Central, East Coast, Northern, North Central, North Eastern, Northeast Frontier, North Western, Southern, South Central, South Eastern, South East Central, South Western, Western, West Central, and Metro Railway (Kolkata). The 18th zone is the South Coast Railway (Visakhapatnam). Assuming the question refers to the structure prior to the most recent addition, 17 is the correct choice among the given options.

36. Which one of the following observations regarding rivers is not made b

Which one of the following observations regarding rivers is not made by the Central Water Commission operating through its network of hydro-meteorological stations?

Water level (gauge)
Silt
Water quality
Shifting in river channel
This question was previously asked in
UPSC CISF-AC-EXE – 2019
The Central Water Commission (CWC) operates a network of hydro-meteorological stations primarily for monitoring river behavior in terms of water quantity and quality. Routine observations from these stations typically include Water Level (Gauge), Silt content (Sediment load), and Water Quality parameters. While CWC may conduct specific studies on river morphology and channel changes, “Shifting in river channel” is generally not a parameter for routine, continuous observation from fixed hydro-meteorological stations in the same way as gauge, silt, or water quality.
– CWC monitors key river parameters through hydro-meteorological stations.
– Standard routine observations include water level, silt/sediment load, and water quality.
– Shifting of the entire river channel is a larger geomorphological process, less amenable to continuous monitoring from a fixed station.
CWC’s mandate includes planning and coordination for water resources development and management, flood forecasting, and monitoring. Data collected from hydro-meteorological stations are crucial for flood forecasting, water management, and planning. While river morphology is studied, especially in the context of river training and flood control works, routine data collection focuses on the properties and flow of water itself at specific points.
