Tasdighi, Ali, PhD, 2017
Ali is a PhD student and a Graduate Research Assistant in department of Civil and Environmental Engineering at Colorado State University. His concentration is Hydrology and Water Resources. Prior to CSU he attended Yazd University (Iran) where he got his B.Sc. degree in Civil Engineering. He started his graduate studies in Civil and Environmental Engineering at Shiraz University (Iran) with concentration on Environmental and Water Resources Engineering. His main interests are in the areas of Hydrology, Rainfall-Runoff modeling, Scaling issues in hydrological processes, Water quality and Water Resources Management. For his current research, Ali has also developed a comprehensive SWAT model for Jordan Lake Watershed in North Carolina. This model was then calibrated and tested in both spatial and temporal scales and several scenarios were defined to evaluate the effectiveness of the current and future agricultural BMPs in reducing the edge-of-field and delivered-to-lake Nutrients. The results will feed an economical model which will evaluate the potential of “Water Quality Trading” between Development and Agriculture sector in this area. Ali_Tasdighi
