Utah Dam Safety and River Cross-Section Data

Overview This feature service provides comprehensive geospatial data related to dam safety, flood risk, and river hydrology within the State of Utah. It integrates multiple layers capturing critical information about dam locations, potential inundation zones from dam breaches, river cross sections, and inspection status of dams to support water resource management and emergency planning efforts. Feature Layers Dam Inventory: This point feature layer details dam locations statewide, sourced from the Utah Division of Water Rights Dam Safety Regulatory Database. It includes information such as dam identification, condition ratings, and inspection records, offering essential data for monitoring dam safety and regulatory compliance. Dam Inundation Zones: Represented as polygons, this layer models potential flood extents resulting from catastrophic dam failures. These worst-case scenarios are derived from Emergency Action Plans and provide critical insights for emergency management, evacuation planning, and risk assessment concerning downstream flood hazards. River Cross Sections Data: This polyline layer depicts detailed river cross sections across various segments, containing hydrological measurements like flow depth, discharge rates, and water surface elevation under different conditions. These data support hydrologic analyses, environmental studies, and flood modeling to inform infrastructure design and environmental impact assessments. Uninspected Dams Overview: This point layer identifies dams within Utah that have not undergone recent inspections. It highlights dams requiring attention for safety assessments and prioritization, aiding government agencies and engineers in resource allocation for inspection scheduling and risk mitigation. Geographic Coverage The data collectively cover the entire State of Utah, providing vital information specific to regional dam safety, flood risks, and river characteristics within this geography. Use Cases Supports water resource managers and engineers in evaluating dam integrity and river dynamics. Assists emergency planners and public safety officials in flood risk visualization and evacuation planning. Facilitates environmental scientists with detailed hydrologic profiles for habitat and impact studies. Aids regulatory agencies in prioritizing dam inspections and maintaining updated safety records.概述 本要素服务（Feature Service）提供犹他州境内与大坝安全、洪水风险及河流水文相关的综合地理空间数据。其整合了多图层数据，涵盖大坝位置、大坝溃决潜在淹没区、河道断面及大坝巡检状态等关键信息，可为水资源管理与应急规划工作提供支撑。 要素图层 大坝清单图层：该点要素图层（Point Feature Layer）详细记录了全州范围内的大坝位置，数据源为犹他州水权部门大坝安全监管数据库。图层包含大坝标识、状态评级及巡检记录等信息，可为大坝安全监控与合规监管提供核心数据支撑。 大坝淹没区图层：该面状要素图层（Polygon Feature Layer）模拟极端大坝溃坝事件引发的潜在洪水波及范围。此类最坏场景情景基于应急行动计划生成，可为应急管理、疏散规划及下游洪水灾害风险评估提供关键决策依据。 河道断面数据图层：该线状要素图层（Polyline Feature Layer）描绘了各河段的详细河道断面，包含不同工况下的水深、流量率及水面高程等水文测量参数。此类数据可支撑水文分析、环境研究与洪水模拟，为基础设施设计与环境影响评价提供参考。 未巡检大坝概览图层：该点要素图层（Point Feature Layer）用于识别犹他州境内近期未接受巡检的大坝，标记出需开展安全评估与优先级排序的对象，可协助政府机构与工程人员合理分配巡检资源，规划巡检日程并开展风险减缓工作。 地理覆盖范围 本数据集覆盖犹他州全域，提供该区域内针对大坝安全、洪水风险及河道特征的专属关键地理空间信息。 应用场景 可为水资源管理者与工程人员评估大坝完整性与河道动态提供数据支撑；协助应急规划人员与公共安全官员开展洪水风险可视化与疏散规划工作；为环境科学家提供详细的水文剖面数据，用于栖息地研究与影响评估；辅助监管机构优先安排大坝巡检工作，并维护最新的安全记录。
