Speech Title: Stormwater harvesting: Is it economically sustainable?

Abstract: Contemporary focus of the whole world is to achieve a sustainable world reducing our exceedingly high ecological footprint through recycling and/or reusing different products, services and resources. For the countries who receive moderate to decent amount of rainfall, stormwater harvesting and reusing the stored stormwater is one of the most effective way of achieving water sustainability as it can significantly reduce the potable water demands for the urban areas. However, its effectiveness depends on many factors, such as amount of rainfall, stormwater demand, roof size and tank volume. In addition, cost of installing such tank and current potable water price play an important role on economic feasibility of such system. In fact, for many cities stormwater harvesting may not be economically feasible, unless current water price and associated policies are not altered. In many cases, installation and maintenance costs of stormwater harvesting may not be recoverable due to lower price of potable water. To establish this a thorough economic and payback period analysis is required. The talk will present few examples of such analyses in regard to stormwater harvesting, its associated costs and expected payback periods.


 

Ying Ouyang, PhD, PH

Southern Research Station, Center for Bottomland Hardwoods Research, USA

Dr. Ying Ouyang is a Research Hydrologist at the Center for Bottomland Hardwoods Research, Southern Research Station, United States Department of Agricultural Forest Service with duty office located on the campus of Mississippi State University. He received B.S. from South China Agricultural University and both M.S. and Ph.D. in soil physics from Oregon State University, USA.  Over the past 30 years, Dr. Ouyang’s working experience has spanned the spectrum from basic to applied research in water resource, hydrology, soil physics, and environmental sciences.  He has actively participated in many dynamic and multidisciplinary programs, including (but not limited): (1) applied and developed watershed models (e.g., BASINS-HSPF, HAWQS, HYDSTRA, and MODFLOW) to analyze hydrological processes and pollutant loads under the changing climate; (2) applied multivariate statistics (e.g., 3D Kriging, Copula, Principal Component Analysis, and Wavelet) to detect spatial distributions and temporal trends of hydrological process and water quality; (3) employed Dynamic Data Driven Application System for real-time estimation of river water quality and tree sap flow using sensor technology and computational algorithms; and (4) developed STELLA models for simulating couple transport of water and contaminants in plant xylem system and vadose zone soil, biomass production and CO2 emission in short-rotation woody crop plantation, and constructed wetland treatment of wastewater.   He has published more than 150 refereed journal articles with 80 refereed articles as the first or sole author ( https://scholar.google.com/citations?user=nPx3ahoAAAAJ&hl=en). Dr. Ouyang has comprehensive editorial experience and had served as associate editor for Journal of Environmental Quality (USA, 15 years) and several other international journals. He was named as Fellow of Soil Science Society of America in 2019 (https://www.srs.fs.usda.gov/news/672) and the recipient of Robert G. Wetzel Award for Water Quality from American Institute of Hydrology in 2021 (https://www.aihydrology.org/aih-award-winners/).

Speech Title:Long-term assessment of evapotranspiration and water yield in a humid subtropical region under changing climate

Abstract:

Evapotranspiration (ET) includes surface evaporation and plant transpiration, while water yield is the water production from surface runoff, vadose zone water discharge, and lateral groundwater flow to reaches.  Evapotranspiration contributes a large amount of water loss and plays a critical role in reducing water yield from watersheds. Traditionally, forest lands are sometimes thought to increase ET and decrease water yield more than those of croplands.  In this study, a long-term comparison of ET and water yield between croplands and forest lands in a humid subtropical region was performed by using the US-Environmental Protection Agency’s Hydrologic and Water Quality System (HAWQS) model and multivariate statistics.  After rigorously calibration and validation with field measured data, the HAWQS model was applied to compare the ET and water yield between the croplands and the forest lands in the Yazoo River basin (YRB), Mississippi, USA.  Simulations show that over the past 50 years from 1966 to 2015, there was 10.8% more water lost from ET in the croplands than in the forest lands, whereas there was 17.3% lesser water yield in the croplands than in the forest lands.  Over the future 50 years from 2021- 2070, there were 42.0% more ET and 20.7% lesser water yield in the croplands than in the forest lands. Results suggest that the forest lands reduced ET and increased water yield as compared to those of the croplands in the YRB.  These findings could change the traditional visions on how forests and crops affect ET and water yields in the humid subtropical regions.

Speech Title: Spatial and temporal distribution characteristics of haze and pollution particles in China based on spatial statistics

Abstract: In recent years, the occurrence and frequency of haze have constantly been increasing, bringing severe threats to people’s daily lives. To this end, this paper discusses the spatial and temporal distribution characteristics of severe haze in China, analyzes the interaction between haze pollution and the influence of economy and energy structure on haze in 31 provinces of China. It provides references for the treatment of haze weather and the prevention and control of air pollution in China. This paper mainly adopts the spatial autocorrelation method. The data processed mainly includes API (Air Pollution Index) and meteorological station data. Combined with the statistical yearbook data, this paper conducts multi-aspect research and exploration. By using statistical methods to study the haze distribution in China, we found that the haze and PM2.5 concentrations were mainly distributed in Beijing-Tianjin-Hebei, Shandong Province, the northern northwest, southeastern Sichuan, and Chongqing. Haze distribution has obvious seasonality, more in winter and less in summer. There are also regional differences in the concentration distribution of urban pollutants. The concentration of SO2 and absorbable particles are relatively high in northern cities. In contrast, that of southern cities is relatively low and changes with seasonal changes.
