| 摘要： | Rain and snowmelt that runs off of roadways carries pollutants. Pollutant event mean concentrations have been developed for various land uses to calculate annual pollutant loads. These were developed for total suspended solids, total phosphorus, and total nitrogen. NHDOT uses the Simple Method for estimating the pollutant load in runoff. This study collected real time in situ measurements to validate the concentrations used in Simple Method calculations for modeling pollutant loads from New Hampshire roadways. Three locations were picked to represent low, medium, and high traffic volume roadways. The actual measured amount of pollutants was compared to the loading predictions of the Simple Method. This study confirmed that using one modeling approach is effective for all New Hampshire roadways. |
