## Nutrient Management Planning Tool

Purpose The nutrient management planning tool was developed to assist watershed managers in determining the most effective ways to reduce harmful nutrient loadings from a watershed.  Currently, the portfolio evaluates management options for wastewater, stormwater and...

## eWSF: Interception

Module: intcp Description Interception of precipitation is computed as a function of the cover density (covden_sum and covden_win) and the storage available (snow_intcp, srain_intcp, and wrain_intcp) for the predominant vegetation on an HRU. HRU precipitation is...

## eWSF: Evapotranspiration over HRUs

Module: potetjh Description The potential evapotranspiration for each HRU (potet) for each time period is computed by: $$potet = jh\_coef * (tavgf − jh\_coef\_hru) * rin$$ where $$jh\_coef$$ = the monthly air temperature coefficient used in Jensen-Haise potential...

## eWSF: Evapotranspiration

Module: transptindex Description The time of the year in which transpiration occurs is specified as a period of months, starting with transp_beg and ending with transp_end. The specific date of the start of transpiration is computed for each HRU using the temperature...

## eWSF: Solar Radiation Distribution over HRUs

Module: ddsolradhru Description *** MLC: Material is from Ddsolrad.xml; no DdsolradHru.xml available? This component has two functions. One is to distribute measured or estimated solar radiation values for a horizontal surface to the slope and aspect...
