摘要

从佐治亚州亚特兰大到北卡罗来纳州罗利的85号州际公路走廊沿线快速发展的城市依靠小型河流供水和废物吸收。这些河流有共同点,包括干旱期间的供水压力、废水稀释的季节性低流量、极端干旱和降水的增加、下游富营养化问题以及高区域水生生物多样性。进一步的挑战包括快速增长;蔓延加剧了水质和基础设施问题;横跨多个县和市的水利基础设施;以及大量的化粪池系统。为了适应人口增长和气候,有必要进行全面的多管辖区合作水资源规划,同时修改政策和基础设施。我们提出了六项行动来提高水基础设施的弹性:提高市政、工业、农业和热电部门的用水效率;采用间接饮用水再利用或闭环系统;允许在干旱期间共享水资源,但规范流域间转移,以保护水生生态系统;提高养分回收率,减少废水中碳和养分的排放;采用绿色基础设施和更好的雨水管理,以减少非点污染物负荷并减轻城市热岛效应;并应用CRIDA框架将气候和水文不确定性纳入水资源规划。

Water supply, waste assimilation, and low-flow issues facing the Southeast Piedmont Interstate-85 urban archipelago

Water supply, waste assimilation, and low-flow issues facing the Southeast Piedmont Interstate-85 urban archipelago

Rapidly growing cities along the Interstate-85 corridor from Atlanta, GA, to Raleigh, NC, rely on small rivers for water supply and waste assimilation. These rivers share commonalities including water supply stress during droughts, seasonally low flows for wastewater dilution, increasing drought and precipitation extremes, downstream eutrophication issues, and high regional aquatic diversity. Further challenges include rapid growth; sprawl that exacerbates water quality and infrastructure issues; water infrastructure that spans numerous counties and municipalities; and large numbers of septic systems. Holistic multi-jurisdiction cooperative water resource planning along with policy and infrastructure modifications is necessary to adapt to population growth and climate. We propose six actions to improve water infrastructure resilience: increase water-use efficiency by municipal, industrial, agricultural, and thermoelectric power sectors; adopt indirect potable reuse or closed loop systems; allow for water sharing during droughts but regulate inter-basin transfers to protect aquatic ecosystems; increase nutrient recovery and reduce discharges of carbon and nutrients in effluents; employ green infrastructure and better stormwater management to reduce nonpoint pollutant loadings and mitigate urban heat island effects; and apply the CRIDA framework to incorporate climate and hydrologic uncertainty into water planning.

期刊介绍: JAWRA seeks to be the preeminent scholarly publication on multidisciplinary water resources issues. JAWRA papers present ideas derived from multiple disciplines woven together to give insight into a critical water issue, or are based primarily upon a single discipline with important applications to other disciplines. Papers often cover the topics of recent AWRA conferences such as riparian ecology, geographic information systems, adaptive management, and water policy. JAWRA authors present work within their disciplinary fields to a broader audience. Our Associate Editors and reviewers reflect this diversity to ensure a knowledgeable and fair review of a broad range of topics. We particularly encourage submissions of papers which impart a ''take home message'' our readers can use.
