In agricultural basin, multiple nutrients were carried from the agricultural land with runoff into the stream or creek. Silver-creek watershed, Madison county, Illinois covers the agricultural basin. Nutrient like Nitrogen and Phosphorous were observed in significant value due to surface runoff from agricultural land to the downstream. Comparison of simulated nutrients were carried out with different precipitation sources. Model calibration for hydrology was performed with CFSR and PRISM in SUFI-2 from January 1998 to December 2001 on daily basis. Similarly, model was validated daily from January 2002 to December 2004.
Comparison of results for change in investigated amount of Nitrogen and Phosphorous in pour points (downstream at confluence point near Kaskaskia River) of watershed reveals that there is a high amount of nutrients in PRISM datasets. The model and analysis facilitates in the favor of using spatial distributed precipitation sources for the accurate analysis on hydrology.
