Abstract

A properly functioning local stormwater drainage system is essential for mitigating flood risks. This study evaluates the quality of roadside drainage channels in three underserved communities in Texas: the Sunnyside neighborhood in Houston (Harris County), a neighborhood in the City of Rockport (Aransas County), and the Hoehn colonia (Hidalgo County). These communities have a history of flooding, are highly socially vulnerable, and rely on roadside ditches as their principal stormwater drainage system for runoff control. Mobile lidar (Light Detection and Ranging) measurements were collected for 6.09 miles of roadside channels in these communities. The raw lidar measurements were processed to evaluate drainage conditions based on the channel's geometric properties, hydraulic capacity, and level of service. The assessment results are linked to a Geographic Information System (GIS) tool for enhanced visualization. Finally, the paper provides insights regarding the quality of stormwater infrastructure in the study communities and discusses their practical implications.

弱势社区雨水基础设施系统的质量：来自德克萨斯州的三个案例研究。

一个正常运行的当地雨水排放系统对于降低洪水风险至关重要。本研究评估了德克萨斯州三个服务不足社区的路边排水渠质量：休斯顿的Sunnyside社区（哈里斯县）、Rockport市的一个社区（阿兰萨斯县）和Hoehn colonia社区（伊达尔戈县）。这些社区有洪水历史，社会高度脆弱，并依靠路边沟渠作为主要的雨水排放系统进行径流控制。移动激光雷达（光探测和测距）测量是在这些社区6.09英里的路边信道上收集的。对原始激光雷达测量进行了处理，以根据河道的几何特性、水力容量和服务水平评估排水条件。评估结果与地理信息系统（GIS）工具相连，以增强可视化效果。最后，本文提供了关于研究社区雨水基础设施质量的见解，并讨论了其实际意义。

期刊介绍： PUBLIC WORKS MANAGEMENT & POLICY: RESEARCH AND PRACTICE IN TRANSPORTATION, INFRASTRUCTURE, AND THE ENVIRONMENT is a peer-reviewed journal for academics and practitioners in public works and the public and private infrastructure industries. This journal addresses the planning, financing, development, and operations of civil infrastructure systems at all levels of society— from federal policy to the demand for, and delivery of, state and local public works services. PWMP solicits manuscripts that convey research results, evaluate management innovations, suggest methods of analysis and evaluation, and examine policy issues.
