Geospatial Data For Streamflow Monitoring Network Design in Louisiana

This resource contains GIS layers necessary to reproduce the analysis of the paper \"Stakeholder-Driven Design of a Flood Risk Streamflow Monitoring Network for Louisiana, USA\" submitted to the Journal of American Water Resources Association (JAWRA). The analysis of this paper is focused on designing a streamflow gauge monitoring network as part of the Louisiana Watershed Initiative (LWI) program to enhance the hydrologic modeling and monitoring capabilities of the state of Louisiana. The monitoring network is optimized to capitalize on the resources made available by the LWI program while serving the needs of the local, regional, and federal stakeholders in Louisiana as much as possible. The factors taken into the optimization algorithm included the collected feedback from the stakeholders, as well as a variety of geospatial and geomorphic characteristics of the Louisiana stream network. The analysis also used the current and past conditions of stream monitoring (e.g., existing and discontinued USGS locations). A final set of 123 stream gauges were selected to be deployed. The shapefile containing this set of gauges is also included in this resource.

本资源包含复现论文《面向美国路易斯安那州的洪水风险径流监测网络的利益相关者驱动设计》分析所需的地理信息系统(GIS)图层，该论文已提交至《美国水资源协会期刊（Journal of American Water Resources Association，JAWRA）》。该论文的分析工作聚焦于设计径流监测站网络，作为路易斯安那州流域倡议（Louisiana Watershed Initiative，LWI）项目的组成部分，以提升路易斯安那州的水文模拟与监测能力。该监测网络的优化设计旨在充分利用LWI项目提供的资源，同时尽可能满足路易斯安那州本地、区域及联邦层面利益相关方的需求。优化算法所考量的因素包括收集到的利益相关方反馈，以及路易斯安那州河网的各类地理空间与地貌特征。本次分析还采用了当前及历史径流监测数据，例如现有及已停用的美国地质调查局（United States Geological Survey，USGS）监测点位。最终选定123个径流监测站用于部署，包含该套监测站的形状文件（Shapefile）也一并收录于本资源中。
