What are the benefits of implementing the 'Integrated Watershed Development Programme'? 1. Prevention of soil runoff 2. Linking the country's perennial rivers with seasonal rivers 3. Rainwater harvesting and recharge of groundwater table 4. Regeneration of natural vegetation. Select the correct answer using the code given below.

1. Prevention of soil runoff — Yes. Watershed development treats catchments through bunding, check dams, contour measures, etc., which reduce erosion and soil loss. Correct.

2. Linking the country's perennial rivers with seasonal rivers — No. River interlinking is a separate large-scale water resources strategy, not a benefit/objective of the Integrated Watershed Development Programme. Incorrect.

3. Rainwater harvesting and recharge of groundwater table — Yes. Watershed works improve infiltration, store runoff, and help recharge aquifers. Correct.

4. Regeneration of natural vegetation — Yes. Area treatment, afforestation, and pasture/common land development are core watershed outcomes. Correct.

Hence, 1, 3 and 4 only are correct.
