项目说明
PROJECT NARRATIVE
《沉积物策略》 是一本操作指南，为希望将疏浚材料有益利用（BUDM）作为美国海岸沼泽生命线的从业者、机构和社区提供共同语言和易于获取的技术参考，重点强调在马里兰州的实施。
在大西洋沿岸，沼泽在日常生活中扮演着至关重要的角色。它们缓冲风暴、过滤水质、支持渔业、储存碳。它们是水上休闲、商业和社区的支柱。然而到2050年，预计近一半将会消失。与此同时，每年有数亿立方码的沉积物通过疏浚被移动——这是一项关键的管理行动，保持港口开放、支流可通航、商业流通。这些系统之间的联系就是沉积物。然而，尽管一个是沉积物来源，另一个是沉积物汇，它们却往往未被协同管理。
这正是有益利用之美：回收沉积物以增强水生生态系统，同时降低疏浚成本。这是一个简单的理念，但实现它却绝非易事。它需要共同愿景、有意识的协调和技术理解。《沉积物策略》 是为经验丰富的从业者和早期采用者提供的BUDM资源。文件分为五个用户友好的部分：
* 背景 — 构建沉积物回收的生态和政策驱动因素
* 实施 — 概述技术考量和实施策略
* 案例研究 — 深入考察典范项目
* 项目管控 — 提供如何驾驭许可和采购路径的洞见
* 项目开发 — 识别关键资金和战略合作机会
BUDM项目的最大障碍是涉及众多组织且海岸条件不断变化的复杂、多学科流程。《沉积物策略》 通过与州和联邦机构、非营利组织和从业者的合作开发而成。它借鉴了同行评审研究、州和联邦监管框架、美国陆军工程兵团最佳实践，以及来自美国各地的典范案例研究。
这些复杂的动态要素被综合为易于阅读的图表、工作流程和比较视觉，为有益利用项目提供完整路线图：从选址、许可、潜在资金选项和合作伙伴，到施工和项目后监测。该指南专为规划者、修复人员和拨款撰写者设计，帮助项目从早期概念推进到实施。
该文件以免费PDF形式通过专业网络、机构渠道和自然保护协会网站分发，具有广泛影响力且易于获取。随着海平面上升和极端风暴事件日益频繁，将疏浚与修复协调一致对海岸韧性而言从未如此紧迫。面临沼泽消失的社区需要持久、具有成本效益的工具，将生态目标与地方优先事项相结合。美国陆军工程兵团的目标是到2030年有益再利用70%的疏浚材料。《沉积物策略》 在这一关键时刻应运而生，作为一本将从业者、机构和社区聚集在一起的操作手册，提供可操作、易于遵循的步骤来启动BUDM项目。

PROJECT NARRATIVE
Sediment Strategies is a how-to guide that provides common language and an accessible technical reference for practitioners, agencies, and communities who want to utilize the beneficial use of dredged material (BUDM) as a lifeline for coastal marshes across the United States, with an emphasis on implementation in Maryland.
Up and down the Atlantic Coast, marshes play an essential role in daily life. They buffer storms, filter water, support fisheries, and store carbon. They are the backbone of aquatic recreation, commerce, and community. Yet by 2050, nearly half are projected to be lost. At the same time, hundreds of millions of cubic yards of sediment are moved annually through dredging—a critical management action that keeps ports open, tributaries navigable, and commerce flowing. The link between these systems is sediment. Yet even though one is a sediment source and the other a sediment sink, they are not often managed together.
That is the beauty of beneficial use: recycling sediment to enhance aquatic ecosystems and lower the cost of dredging. It is a simple idea, but making it happen is anything but simple. It requires a shared vision, intentional coordination, and technical understanding. Sediment Strategies is a BUDM resource for both seasoned practitioners and early adopters. The document is organized in five user-friendly sections:
* Context — Frames the ecological and policy drivers for sediment recycling
* Implementation — Outlines technical considerations and implementation tactics
* Case Studies — In-depth examinations of exemplary projects
* Project Controls — Gives insight on how to navigate permitting and procurement pathways
* Project Development — Identifies key funding and strategic partnership opportunities
The biggest hurdle to BUDM projects is the complex, multidisciplinary process involving numerous organizations and constantly changing coastal conditions. Sediment Strategies was developed through collaboration with state and federal agencies, nonprofits, and practitioners. It draws from peer-reviewed research, state and federal regulatory frameworks, USACE best practices, and exemplary case studies from across the United States.
This complex collection of moving parts is synthesized into easy-to-read diagrams, workflows, and comparative visuals that offer a complete roadmap for a beneficial-use project: from site selection, permitting, and potential funding options and partners through construction and post-project monitoring. Designed for planners, restoration staff, and grant writers alike, the guide helps move projects from early concept to implementation.
Distributed as a free PDF through professional networks, agency channels, and The Nature Conservancy’s website, the document has broad reach and is easily accessible. As sea levels rise and extreme storm events become more common, aligning dredging with restoration has never been more urgent for coastal resilience.
Communities facing marsh loss need durable, cost-effective tools that align ecological goals with local priorities. The U.S. Army Corps of Engineers aims to beneficially reuse 70% of dredged material by 2030. Sediment Strategies meets this pivotal moment as a playbook that brings practitioners, agencies, and communities together and provides actionable, easy-to-follow steps to initiate a BUDM project.
