1. 제1차 응용생태공학 화상 세미나 (KSEIE Webinar)
- 일시: 2020년 4월 9일 (목) 오전 10:00-11:00
- 연사: 송근예 (Keunyea Song, Natural Resource Scientist, Washington State Department of Ecology)
- 제목: Receiving water monitoring program related to Stormwater management and regulation in Western Washington
- 내용: Stormwater has been identified as a major source of contamination entering the Puget Sound and has been implicated in the degradation of receiving water habitats and biota. Department of Ecology issues stormwater permit to regulate and manage stormwater to minimize its impacts on receiving water. As one of the stormwater permit requirements, receiving water monitoring program was developed to monitor receiving water health, and how their conditions change over time related to urban growth and stormwater management efforts in the region. During the first 5 years of the monitoring program, 2014-2019, the stream and nearshore monitoring were first conducted, lessons learned, and the first set of regional status reports published. Since the first round of monitoring, we made a few adjustments to the study design, which will be applied to studies starting in 2020.

- 제목: Modeling the interaction between climate, forest ecosystem and hydrology to estimate catchment dissolved organic carbon and nitrate export
- 내용: Watersheds in the Catskill Mountain region of New York State have historically experienced soil and stream acidification due to atmospheric SO2 and NOx. deposition. Recent studies in northern Europe and North America have shown increased trends in dissolved organic carbon (DOC) in streams and lakes. Reductions of acid deposition and increasing temperature and extreme hydrologic events have been suggested as a cause of increasing DOC. DOCs are known precursors for disinfection by-products (DBPs) some of which are regulated due to the suspected health impacts. Watersheds in the Catskills are the major source of drinking water for New York City and other communities in the region. Potential increases in DOC could therefore lead to increases in the DBP concentration in treated water, and a concern for regulating the water quality in water supply watersheds. Therefore, understanding and predicting the magnitude and variability of watershed DOC and nitrate become important for informing watershed and water supply management. In this study, we used a distributed process‐based ecohydrological model (Regional Hydro‐Ecological Simulation System [RHESSys]) to explore controls and predict streamflow, DOC and nitrate in Biscuit Brook; a sub-watershed in the Catskills Mountain. Biscuit Brook is a forested headwater catchment of the Neversink Reservoir, part of the New York City water supply system in the Catskill Mountains. Three different model structures of RHESSys were proposed to explore and evaluate hypotheses addressing how vegetation phenology, and hydrologic connectivity between deep groundwater and riparian zones influence streamflow and DOC/nitrate export. In addition, the impact of atmospheric N deposition in these simulations was tested. Model results showed that incorporating dynamic phenology (climate-condition-varying timing of growing season) improved model agreement with measured streamflow in growing seasons and fall DOC concentration, compared with a static phenology (a fixed timing of growing season). Additionally, the connectivity of deep groundwater flux through riparian zones with dynamic phenology improved streamflow and DOC flux in low flow conditions. For stream nitrate, incorporating the connectivity of riparian zone and deep groundwater significantly improved summer/fall stream nitrate concentration, compared with the other two models. Stream nitrate concentration prediction is also sensitive to the timing and magnitude of atmospheric N deposition rate. In summary, this study suggests the importance of inter-annual vegetation phenology and the connectivity of riparian zone and deep groundwater storage and accurately specified atmospheric N deposition rate in the hydrology, stream DOC/nitrate dynamics in this forested watershed.
