During a storm event, stormwater runoff is generated, and some discharge enters outlet pipes that lead to flow in outlet channels. With the increase in flow of discharge, the volume of stormwater entering the channel increases. These discharges from outlet pipes can result in erosive damage to the subsequent outlet channel and further downstream. Along with this, various pollutants wash into the channels and deteriorate the water quality entering the receiving waters and further damages the ecology. This research was conducted to understand the water quality and hydrology characteristics of flow from outlet pipes along with highway sites. For this work, several water quality parameters were examined, and the hydrologic response was determined along with three points of the monitored outlets and their respective channels. Water samples were collected after every eligible storm event and sent for laboratory analysis. The pollutant concentration results obtained from laboratory tests were further utilized in an excel-based load estimation tool known as a simple method. The tool was deployed for the estimation of pollutant loads generated by the watershed. The simple method utilizes various data sets related to the watershed, along with pollutant concentrations, to estimate pollutant loads that can be transmitted by the water channels.The hydrological analysis was conducted to understand the relation of rainfall to change in the water-level. This analysis can help to understand the selected channels’ response to water runoff caused by rainfall. The data used for this analysis were changes in the channels’ water level on a 2-minute interval and water discharge from the channel. The results from water quality, hydrological analysis, and pollutant load estimation can be used in future studies to mitigate pollutant loads in receiving waters. The results can also contribute to planning stormwater control measures and tools that analyze outlets and flow from it.
