Subjects: Environmental Engineering, Environmental Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Other Civil and Environmental Engineering, Other Environmental Sciences, Sustainability, Water Resource Management
450 million people live on river deltas and thus on land that is precariously low above the sea level and sinking because of human activities and natural processes. Although global debates around coastal risk typically focus on sea level rise, it is sinking lands and rising seas that together endanger lives and livelihoods in river deltas. However, the ability to quantify and address those risks [...]

Most of these efforts rely on server resources for computation and data [...]
A machine learning approach to water quality forecasts and sensor network expansion: Case study in the Wabash River Basin, USA
Published: 2022-04-06
Subjects: Civil and Environmental Engineering, Engineering, Environmental Sciences, Other Civil and Environmental Engineering, Physical Sciences and Mathematics, Water Resource Management
Midwestern cities require forecasts of surface nitrate loads to bring additional treatment processes online or activate alternative water supplies. Concurrently, networks of nitrate monitoring stations are being deployed in river basins, co-locating water quality observations with established stream gauges. However, tools to evaluate the future value of expanded networks to improve water quality [...]
Advancing on the Promises of Techno-ecological Nature-based Solutions: A Framework for Green Technology in Water Supply & Treatment
Published: 2021-06-10
Subjects: Environmental Engineering, Natural Resources Management and Policy, Other Civil and Environmental Engineering, Sustainability, Water Resource Management
Nature-based Solutions (NBS) are increasingly proposed for effectively and adaptively addressing societal challenges such as water security and natural disasters. However, NBS that are exclusively reliant on natural processes are not fit-for-purpose for the provision of safe drinking water—some range of built technology is required. There is a wide spectrum of techno-ecological NBS—“green [...]
