Step 1: Understanding the Concept:
Watershed management is the integrated management of land, water, and vegetation within a drainage basin. Its primary objective is to conserve natural resources, improve water availability, reduce soil erosion, and enhance sustainable agricultural productivity.
Step 2: Detailed Explanation:
The major objectives include:
Runoff utilization: Capturing and storing runoff for irrigation and groundwater recharge.
Groundwater enhancement: Increasing infiltration through check dams, contour bunds, and recharge structures.
Forest and fodder development: Improving vegetation cover to reduce erosion and support livestock.
Although watershed treatments may indirectly reduce flood intensity, moderating floods in downstream areas is not considered the primary objective. The focus remains on conservation and resource development within the watershed itself.
Step 3: Final Answer:
The incorrect objective is To moderate floods in the downstream areas. Therefore, the correct answer is (B).
