Grand River – Runoff Areas<br />
• Results from hydrologic modeling were used<br />
to estimate where runoff is occurring across<br />
the watershed.<br />
• These results help define functional runoff<br />
units on the landscape. By classifying these<br />
runoff units the significance of these<br />
functional units can be depicted.<br />
• High runoff area are associated with high<br />
sediment deliver that has an implications to<br />
water quality. These areas are also have<br />
implications to flooding.<br />
1. 10% of the total area, and produces 25%<br />
of the runoff<br />
2. 30% of the total area, and produces 60%<br />
of the runoff<br />
3. 45% of the total area, and produces 80%<br />
of the runoff<br />
4. Remaining 55% of the total area produces<br />
20% of the runoff
