This study seeks to understand the hydrological interactions and habitat diversity of the Napo River, a major Amazon tributary that drains 100,000 km2 of Andean forest lands. It is a sparsely inhabited region of exceptional biodiversity. The lowland Napo River (860 km) has been identified by development groups as a key link for a continent-wide navigation network that would connect Pacific ports, Andean highways, and the mainstem Amazon. This proposed conversion of the Napo River into an industrial waterway would require engineering to increase and stabilize its depth, which could lead to significant alterations to the hydrology of adjacent floodplains. There has been little ecological work on the hydrology of the river and its impact on floodplains that can underpin a scientific assessment, although it is known that local inhabitants depend on these resources and on ecological processes dictated by the flood pulse of the river. This study will identify the temporal and spatial variability of water levels in the region, assess the extent and diversity of floodplains and wetlands, and determine how alteration of the water-level regime of the river may affect biodiversity and ecosystem services associated with floodplains and wetlands of the Napo River system. Remote sensing techniques will be combined with data from 100s of deployed temperature sensors, water chemistry measurements, and applied in a hydrologic model.The outcomes of this research will improve the current understanding of floodplain-river interactions, and as such, can contribute to the scientific basis upon which decisions about this large development project, as well as about biodiversity and related conservation targets, can be informed.

这项研究旨在了解纳波河的水文相互作用和栖息地的多样性，纳波河是一项主要的亚马逊支流，耗尽了100,000 km2的安第斯森林土地。这是一个稀有人工的特殊生物多样性地区。 开发小组已将低地纳波河（860公里）确定为跨大陆范围的导航网络的关键链接，该网络将连接太平洋港口，安第斯山脉高速公路和亚马逊主要系统。这项提议将纳波河转化为工业水路的拟议转换将需要工程学来增加和稳定其深度，这可能会导致对邻近洪泛区的水文的重大改变。关于河流的水文学及其对洪泛区的影响几乎没有生态学，尽管众所周知，当地居民依赖这些资源以及河流洪水脉动决定的生态过程。这项研究将确定该地区水位的时间和空间变异性，评估洪泛区和湿地的程度和多样性，并确定河流状态的变化如何影响生物多样性和与Napo River System洪泛区和湿地相关的生物多样性和生态系统服务。遥感技术将与来自100 s部署温度传感器，水化学测量的数据相结合，并在水文模型中应用。这项研究的结果将改善对洪泛区河流相互作用的当前理解，因此，可以为这项大型开发项目以及有关生物跨性别项目以及有关生物跨性别的目标以及信息的科学依据，以及有关该决定的科学依据。
