The term 'Spring Flood' can be summarized by the word 'runoff', which is a six-letter word. Runoff is the process of water from rain or melting snow that flows over the land surface and into streams, rivers, and other bodies of water. It is a common occurrence during the spring season when snow melts and heavy rains occur. Runoff is an important part of the water cycle and helps to replenish groundwater supplies.
