Forestal Arauco (FA), a global manufacturer of forest products, manages more than 1 million ha of forest plantations and oversees the conservation of more than half a million hectares of native forest and vegetation in Brazil, Argentina and Chile. In 2008, FA responded to local concerns about the effect of plantations on water resources and commenced streamflow monitoring in catchments in the coastal range of central‐southern Chile between 35° and 39° of latitude south. This data note presents an overview of daily streamflow and rainfall records for 10 small catchments (18–112 ha) from 2008 to 2018. The catchments are covered by three different forest types, namely native forest (2), pine plantations of different ages (6) and eucalypt plantations (2). All of these catchments share similar metamorphic geology. A 90° V notch weir was built at each catchment outlet and data collected at 5 min interval using a pressure transducer that was calibrated monthly. The dataset is part of a research programme aiming to improve our understanding about the role of forest plantations on water balance at a stand and catchment level. It also includes the rainfall data from these catchments estimated using a combination of local rain gauges and data from the longer term records of the Chilean Directorate of Water. This dataset can be used in hydrological modelling and in a wide range of research questions and water management issues regarding forest plantations in a Mediterranean climate.

森林Arauco实验研究流域;智利中南部的10个不同森林类型的流域的每日降雨径流

全球性林产品制造商Forestal Arauco(FA)管理着超过100万公顷的人工林,并监督巴西,阿根廷和智利超过半百万公顷的原生森林和植被的保护。2008年,FA回应了当地对人工林对水资源影响的担忧,并在智利中南部纬度以南35°至39°之间的沿海地区的集水区开始了流量监测。本数据说明概述了2008年至2018年10个小流域(18-112公顷)的日流量和降雨量记录。流域覆盖三种不同的森林类型,即原生森林(2),不同年龄的松树人工林( 6)和桉树人工林(2)。所有这些流域都具有相似的变质地质。在每个集水口处建立一个90°V的缺口堰,并使用每月校准的压力传感器每隔5分钟收集一次数据。该数据集是一项研究计划的一部分,旨在增进我们对林分和流域水平上人工林对水平衡的作用的理解。它还包括结合当地雨量计估算的这些流域的降雨数据以及智利水利局长期记录的数据。该数据集可用于水文建模以及有关地中海气候下人工林的广泛研究问题和水管理问题。该数据集是一项研究计划的一部分,旨在增进我们对林分和流域水平上人工林对水平衡的作用的理解。它还包括结合当地雨量计估算的这些流域的降雨数据以及智利水利局长期记录的数据。该数据集可用于水文建模以及有关地中海气候下人工林的广泛研究问题和水管理问题。该数据集是一项研究计划的一部分,旨在增进我们对林分和流域水平上人工林对水平衡的作用的理解。它还包括结合当地雨量计估算的这些流域的降雨数据以及智利水利局长期记录的数据。该数据集可用于水文建模以及有关地中海气候下人工林的广泛研究问题和水管理问题。
