A design aid for determining width of filter strips.pdf

Watershed planners need a tool for determining width of filter strips that is accurate enough for developing cost-effective site designs and easy enough to use for making quick determinations on a large number and variety of sites. This study employed the process-based Vegetative Filter Strip Model to evaluate the relationship between filter strip width and trapping efficiency for sediment and water and to produce a design aid for use where specific water quality targets must be met. Model simulations illustrate that relatively narrow filter strips can have high impact in some situations, while in others even a modest impact cannot be achieved at any practical width. A graphical design aid was developed for estimating the width needed to achieve target trapping efficiencies for different pollutants under a broad range of agricultural site conditions.

The Feitsui reservoir is a major water supply source for more than five million people in Northern Taiwan. The reservoir water quality has been good, but is threatened by eutrophication due to excessive nutrient input and siltation due to sediment loads. Recently, the water authorities in Taiwan have made considerable efforts to devise strategies using watershed conservation practices for the protection of Feitsui reservoir water quality. The control of non-point source pollution (NPS) represents one of the major strategies and the use of best management practices (BMPs) is under careful consideration.

白银行业深度报告：全球主要银企及矿山梳理 供需格局有望持续改善.pdf

近几年白银价格较为 低迷，导致银企资本支出下降显著。结合银矿4-6 年的建设周期，未来新 增矿山供给有限。同时受制于低银价，再生银产量持续低迷。2017 年世 界矿山银产出8.50 亿盎司，同比下降4.1%。自2015 年8.91 亿盎司历史 高位后，已连续两年出现回落。

2019全球展望：宏观、地区和股票(英文版).pdf

We would sell Developed Market equities into rallies, but remain positive on Emerging Markets, and forecast only a very moderate 3% price return for MSCI AC World in 2019. Our scorecard of preconditions for a bear market now suggests bullish and bearish factors are evenly matched (though the latter are growing), while the risk of a policy error is exceptionally high. We believe US yields are close to a peak. We see the risk/reward in credit as being far less attractive than equities in 2019.
