Spatio-Temporal Statistical Modeling of Livestock Waste in Streams. Livestock Series Report 5
利用德克萨斯州北部Bosque流域17个监测点15个月的每日数据，建立模型预测溪流中硝酸盐浓度，帮助理解牲畜养殖对水质的影响。
Surface water runoff from large livestock operations finds its way into streams, rivers, and ultimately the larger watershed area. In this paper, the model measures the nitrate concentrations in the upper North Bosque (Texas) watershed, which is a region of concentrated dairy operations. Using 15 months of daily data collected at 17 stream monitoring sites allows the authors to obtain optimal predictions of unknown nitrate concentration at all stream locations at any given time, along with a measure of their variability.
