English हिन्दी
Area of a micro-watershed is :
माइक्रो-वाटरशेड (Micro-watershed) का क्षेत्रफल कितना होता है?
EXPLANATION Rainwater Harvesting, In-situ Moisture Conservation, Contingency Crop Planning and Watershed Management
  • According to the All India Soil and Land Use Survey (AISLUS) classification, watersheds are categorized hierarchically by catchment drainage area:
  • Macro-watershed: $\gt 50,000\text{ ha}$
  • Sub-watershed: $10,000\text{ to } 50,000\text{ ha}$
  • Milli-watershed: $1,000\text{ to } 10,000\text{ ha}$
  • Micro-watershed: $100\text{ to } 1,000\text{ ha}$
  • Mini-watershed: $10\text{ to } 100\text{ ha}$
  • Thus, the standard geographical area for a micro-watershed is 100–1000 ha, confirming Option 2.
  • अखिल भारतीय मृदा एवं भूमि उपयोग सर्वेक्षण (AISLUS) वर्गीकरण के अनुसार वाटरशेड का क्षेत्रफल आधारित पदानुक्रम:
  • मैक्रो-वाटरशेड: > 50,000 हेक्टेयर
  • सब-वाटरशेड: 10,000 से 50,000 हेक्टेयर
  • मिली-वाटरशेड: 1,000 से 10,000 हेक्टेयर
  • माइक्रो-वाटरशेड: 100 से 1,000 हेक्टेयर
  • मिनी-वाटरशेड: 10 से 100 हेक्टेयर
  • अतः माइक्रो-वाटरशेड का क्षेत्रफल 100-1000 हेक्टेयर (विकल्प 2) होता है।
