Computer vision-based measurement of stormwater discharge: proof-of-concept
Published: 2025-01-29
Subjects: Civil and Environmental Engineering
Stormwater systems, as infrastructure draining urban water runoff into water bodies, are pivotal in preserving municipal functionality while they play an important hydrological and environmental role. As such, the ability to reliably monitor stormwater outflow in many locations could provide valuable information for water managers. However, in most cases stormwater outlets have not been designed [...]

Published: 2025-01-21
Subjects: Atmospheric Sciences, Civil and Environmental Engineering, Engineering, Environmental Engineering, Meteorology, Oceanography, Oceanography and Atmospheric Sciences and Meteorology
The Kenyan Rift Valley has experienced an abrupt and significant rise in its lake levels since 2010, followed by a more rapid rise since 2020. This paper examines the dynamic changes in precipitation patterns and their climatic drivers in the Kenyan Rift Valley region from 1981 to 2021, focusing on Lake Nakuru. Notably, in 2010, a pivotal change point in precipitation aligns with the rising water [...]
