2001 Provo River Analysis By Month

As civil engineers, it is important to understand the status and outlook of our water. Streamflow is one way to represent the hydrologic status in an area. In Provo, we often talk about there being a drought for the last several years. However, there are also lots of different datasets for streamflow. This dataset used data from GEOGLOWS, the National Water Model and observed datasites from NWIS from data.cuahsi.org. I took rivers from Provo in these datasets and looked at there timeseries. Then, I compared the monthly values in 2001 to the normal values from 1990 to 2020. Each month is classified by each data source. I found that the different data sources have different classifications, but all sources put that year as being a year that was more dry.

作为土木工程师，明晰水资源的现状与发展前景是一项核心要务。河川径流量是表征区域水文状态的关键指标之一。普罗沃（Provo）地区近年来长期处于干旱状态已是当地普遍关注的议题，但针对河川径流量的公开数据集类型丰富多样。本数据集整合了来自GEOGLOWS、国家水模型（National Water Model）以及data.cuahsi.org平台上NWIS实测站点的观测数据。本研究从上述数据集中提取了普罗沃地区的河流径流量时序数据，将2001年各月的径流量数值与1990年至2020年的同期基准平均值进行对比，并依据各数据源分别对各月的水文状态进行分类。研究发现，不同数据源给出的分类结果存在一定差异，但所有数据源均将2001年判定为偏干旱年份。
