By exploring new technologies and more cost-effective methods of hydro-environmental sensing my research aims to improve monitoring methods for the water industry, reduce costs and improve water system management.
dr andy nichols
Andy joined the department in 2015 after working as research associate on a number of industry and EPSRC funded projects. He was recruited as a Lecturer for the new cross-faculty General Engineering interdisciplinary degree program.
Andy’s research focuses on the development of new sensing technology, primarily for the water industry, to improve and provide new opportunities for the measurement and management of processes in water courses, from rural rivers to urban sewers. His research uses a range of sensing principles including optical, electrical, acoustic and infrared. His expertise in designing new instrumentation and experimental facilities enables the sensing and understanding of hydro-environmental processes in the natural and built environments. Andy also supports companies in testing and validating their own sensing technologies.
One of Andy’s areas of interest is the science of flowing water surfaces, and the technology to measure them. This allows the use of their unique signatures to identify the hydraulic processes occurring within the flow. He aims to develop links with other important hydro-environmental processes such as greenhouse gas evasion, pollutant mixing, and sediment transport and has worked on a number of sensing technologies for this purpose, resulting in two international patent applications and a number of national awards. His work ranges from laboratory studies in collaboration with academic colleagues to field studies with industrial partners and local authorities.
