ENHANCING RAINFALL-RUNOFF POLLUTION MODELING BY INCORPORATION OF NEGLECTED PHYSICAL PROCESSES
《农业科学与工程前沿(英文)》 2023年 第10卷 第4期 页码 553-565 doi: 10.15302/J-FASE-2023519
The growing need to mitigate rainfall-runoff pollution, especially first flush, calls for accurate quantification of pollution load and the refined understanding of its spatial-temporal variation. The wash-off model has advantages in modeling rainfall-runoff pollution due to the inclusion of two key physical processes, build-up and wash-off. However, this disregards pollution load from wet precipitation and the relationship between rainfall and runoff, leading to uncertainties in model outputs. This study integrated the Soil Conservation Service curve number (SCS-CN) into the wash-off model and added pollutant load from wet precipitation to enhance the rainfall-runoff pollution modeling. The enhanced wash-off model was validated in a typical rural-residential area. The results showed that the model performed better than the established wash-off model and the commonly-used event mean concentrations method, and identified two different modes of pollution characteristics dominated by land pollution and rainfall pollution, respectively. In addition, the model simulated more accurate pollutant concentrations at high-temporal-resolution. From this, it was found that 12% of the total runoff contained 80% to 95% of the total load for chemical oxygen demand, total N, and total P, whereas it contained only 15% of the total load for NH4+-N. The enhanced model can provide deeper insights into non-point pollution mitigation.

世界各地城市高层建筑的蓬勃发展使人们对其抗风性能提出了新要求。这涉及选择建筑外形使其风荷载最小化和有效传递荷载的结构拓扑形式。现行方法通常是在设计中寻找最优外形,但是会将其限定在静态或固定的建筑形式下。以台北101和哈利法塔的外形设计为例,气动外形修正通过修改建筑物的外观设计在减小风荷载和风致建筑物响应方面有很好的应用前景。在这些建筑物设计中,引入了横截面的倒角调整和锥度设计。除此之外,另一种引人注目的方案是设计一个能适应城市高楼林立复杂风环境变化的建筑,即设计动态立面。建筑形状的自主动态变形超越了传统静态形状优化设计,通过将传感、计算、传动装置和工程信息学融合在一起的信息物理系统而实现,并在本研究中进行了论证。新提出的方法将使建筑物能够智能地改变其轮廓,最大限度减弱动态风荷载激励,并有望通过利用计算设计的迅速发展,推动高层建筑设计从传统的静态立面转变为动态立面。

This study aims to explore the prevalence and determinations of physical inactivity among hospital employees in Shanghai, China. A cross-sectional study of 4612 employees aged 19 to 68 years was conducted through stratified cluster sampling from different classes of Shanghai hospitals in 2011. The total physical activity was evaluated using the metabolic equivalent according to the Global Physical Activity Questionnaire. Among the participants, 38.5%, 32.3%, and 64.6% of the employees are inactive at work, commuting, and taking leisure time, respectively. Up to 41.8% of the men and 37.8% of the women (P = 0.012) are physically inactive. When the age and educational level are adjusted, male doctors and medical technicians show a higher percentage of physical inactivity than male workers in logistics (P = 0.001). Among females, employees who are working in second- and third-class hospitals show a higher proportion of physical inactivity than those who are working in community health care centers. Logistic regression analyses show that the odds ratios (ORs) of leisure-time physical inactivity associated with the intensity of physical activity at work are 2.259, 2.897, and 4.266 for men (P<0.001) and 2.456, 3.259, and 3.587 for women (P<0.001), respectively. The time during commuting activities is significantly associated with leisure-time physical inactivity in either sex (OR= 2.116 for men and 2.173 for women, P<0.001). Hospital employees, particularly doctors and medical technicians, show a higher proportion of physical inactivity than other inhabitants in Shanghai. The time and intensity of activity at work and commuting are associated with leisure-time activities.
