PATHWAYS brings together a multidisciplinary team crossing technology, systems thinking and society to aid the understanding of water quality. The project undertakes fundamental research, through to end-user delivery. We will develop new insights, approaches and technologies that support the needs of end-users to provide protection for communities and ecosystems using co-designed and appropriately applied technologies. We will do this, by developing improved, validated decision support tools to address the requirements for the protection and enhancement of natural water quality. This will inform end-user decisions made by environmental regulators and policymakers, engineering consultants and water utilities.The proposed study will employ a range of novel fundamental research approaches, including laboratory and field tracer studies, data interpretation and simulations, to ascertain the pathways and evolution of pollutants within a range of flow domains. In order to do so, the programme will investigate water quality characteristics paying special attention to the relationship between a number of critical parameters including physical, chemical and biological variables. The characteristics of the microbial communities in river water and sediments (microbial diversity) and their pollutant-degrading potential will be assessed and how they are affected by physical and chemical controls such as: boundary (biofilm and permeability), shape (cross-section and planform), and nutrients (reactive nitrogen and phosphorous) in four flow domains: rivers, lakes and wetlands and near-shore in the Ulhas River / Thame Creek Catchment (Mumbai Metropolitan Region, India). This will elucidate how direct discharge and diffuse scenarios affect interactions between physical controlling effects, microbial community composition and pollutant biodegradation rates.Our approach is unique in that the design and implementation of the technology is informed through understanding of local community, where an appropriate solution or systems structure is not presumed. The accessibility of robust low-powered sensors, communication technologies is providing great opportunities for locally orientated data collection focussed on community concerns. Using a citizen science approach, these advances can be used to develop efficient, user-friendly water monitoring strategies and systems based on innovative technologies, providing authorities, communities and other end-users real-time data.

PATHWAYS汇集了一个跨技术、系统思维和社会的多学科团队，以帮助了解水质。该项目承担基础研究，直至最终用户交付。我们将开发新的见解、方法和技术，以支持最终用户的需求，利用共同设计和适当应用的技术为社区和生态系统提供保护。为此，我们将开发改进的、经过验证的决策支持工具，以满足保护和提高自然水质的要求。这将为环境监管机构和决策者、工程顾问和水务公司的最终用户做出决定提供信息。拟议的研究将采用一系列新颖的基础研究方法，包括实验室和现场示踪剂研究、数据解释和模拟，以确定污染物在一系列流动域中的途径和演变。为此，该方案将调查水质特征，特别注意包括物理、化学和生物变量在内的若干关键参数之间的关系。将评估河流水和沉积物中微生物群落的特征（微生物多样性）及其污染物降解潜力，以及它们如何受到物理和化学控制的影响，例如：四个流域中的边界（生物膜和渗透性）、形状（横截面和平台）和营养（活性氮和磷）：河流、湖泊和湿地以及乌尔哈斯河/ Thame河流域的近岸（印度孟买大都会区）。这将阐明直接排放和扩散情景如何影响物理控制效果、微生物群落组成和污染物生物降解率之间的相互作用。我们的方法是独特的，因为技术的设计和实现是通过对当地社区的理解来实现的，而不是假设一个适当的解决方案或系统结构。强大的低功率传感器和通信技术的可访问性为以社区关注为重点的面向本地的数据收集提供了巨大的机会。利用公民科学方法，这些进展可用于开发基于创新技术的高效、用户友好的水监测战略和系统，为当局、社区和其他最终用户提供实时数据。
