when does the river grow wider and broader

Explanation:
Hence rivers flow progressively faster on their journey downstream. Width and depth increases as more water is added from tributaries. Gradient (the slope of the land) decreases as rivers flow because the river meanders across the land rather than erode into it and follow a straight path as it does in the source.

Answer:
Channel Patterns
However, downstream the water flow meanders due to the erosion of outer parts of bends in the river. The river becomes wider as the meandering channel is eroded and washes away more materials along the riverbank. The cross-sectional area of the river, therefore, becomes larger.
