TEMPORAL CHANGES IN THE YADKIN RIVER FLOW VERSUS SUSPENDED SEDIMENT CONCENTRATION RELATIONSHIP1

ABSTRACT: Dynamic linear models (DLM) and seasonal trend decomposition (STL) using local regression, or LOESS, were used to analyze the 50‐year time series of suspended sediment concentrations for the Yadkin River, measured at the U.S. Geological Survey station at Yadkin College, North Carolina. A DLM with constant trend, seasonality, and a log₁₀ streamflow regressor provided the best model to predict monthly mean log₁₀ suspended sediment concentrations, based on the forecast log likelihood. Using DLM, there was evidence (odds approximately 69:1) that the log₁₀ streamflow versus log₁₀ suspended sediment concentration relationship has changed, with an approximate 20 percent increase in the log₁₀ streamflow coefficient over the period 1981 to 1996. However, sediment concentrations in the Yadkin River have decreased during the decade of the 1990s, which has been accompanied by a concomitant increase in streamflow variability. Although STL has been shown to be a versatile trend analysis technique, DLM is shown to be more suitable for discovery and inference of structural changes (trends) in the model coefficient describing the relationship between flow and sediment concentration.

Shapiro台风风场模型及其数值模拟

我国东南沿海是世界上台风最集中的地区之一,也是我国经济最发达和财富最集中的地区,台风引起的灾害损失巨大.数值模拟方法是目前进行台风危险性分析和估算极值风速普遍采用的方法,已有较多风场模型应用于台风区的极值风速估算,Shapiro风场模型是其中之一.首先介绍了Shapiro台风风场模型,然后采用有限差分法求解描述该风场模型的非线性偏微分方程组,利用两个实测台风的风速记录对该模型进行了验证,对该风场模型在我国东南沿海地区的应用做了初步尝试.     

一体化-膜生物反应器物理清洗效果的研究

在一体式一膜生物反应器处理生活污水的基础上，考察了运行过程中膜污染情况。试验结果表明，膜外表面沉积污泥是造成膜污染的主要因素，在活性污泥混合液中搓洗膜丝，是一种方便而有效的清洗方式。间歇式运行方式的停抽期间最低剩余抽吸压力可用来表征运行过程中膜过滤性能的变化。
