Plants in river corri- <br />dors provide natural floodwater storage capacity by retarding runoff and increasing the <br />rate at which water infiltrates soils. This can result in the reduction of flood peaks <br />downstream. Vegetation also allows the water to spread horizontally and more slowly, <br />rather than running directly from upland areas into rivers or streams. In addition, the <br />leaf litter and soils associated with floodplain vegetation act as sponges in absorbing <br />some floodwaters. Vegetation also passes water to the atmosphere through transpira- <br />tion. <br /> <br />.,. <br /> <br />Figure 8 - Nutrient Cycling in a floodplain <br />fore~.ted wetland ecosystem. <br /> <br />. <br />o <br />l <br />~ <br />~ <br />~ <br />
