Key Syllabus Units Covered (Official IGNOU ONR-002 Curriculum)

• Block 1: Elementary Hydrology
  • Fundamentals of hydrologic cycle and its components (precipitation, evaporation, transpiration, infiltration, runoff).
  • Concepts of watershed and drainage basin, including morphology and hydrologic response.
  • Introduction to hydrologic measurements and units (e.g., mm, cm³, m³/s).
• Block 2: Rainfall and Runoff Measurement
  • Types of rain gauges (tipping bucket, weighing type) and their calibration.
  • Runoff measurement techniques (stream gauging, weirs, flumes) and their applications.
  • Data analysis for rainfall intensity-duration-frequency (IDF) curves and runoff volume estimation.
• Block 3: Water Quality
  • Physical, chemical, and biological parameters of water quality (pH, turbidity, dissolved oxygen, BOD, COD).
  • Sources of water pollution (industrial, agricultural, domestic) and their impact on hydrologic systems.
  • Standards for drinking water and irrigation water quality (IS/WHO guidelines).
• Block 4: Hydrologic Data Analysis (Optional Extension)
  • Statistical methods for hydrologic data (probability distributions, frequency analysis).
  • Use of software tools (e.g., HEC-HMS, R) for hydrologic modeling.
