Water Quality Sampling Frequency Analysis of Surface Freshwater: A Case Study on Bristol Floating Harbour

Water quality monitoring is essential to understanding the complex dynamics of water ecosystems, impact human infrastructure on them and ensure safe use resources for drinking, recreation transport. High frequency in-situ systems are being increasingly employed in schemes due their much finer temporal measurement scales possible reduced cost associated with manual sampling, manpower time needed process results compared traditional grab-sampling. Modelling data at higher reduces uncertainty allows capture transient events, although potential constraints storage, inducement noise, power conservation it worthwhile not using an excessively high sampling frequency. In this study, recorded Bristol's Floating Harbour as part local UKRIC Urban Observatory activities presented analyse events captured by current laboratory analysis scheme. The components time-series analysed work towards necessary temperature, dissolved oxygen (DO), fluorescent organic matter (fDOM), turbidity conductivity indicators quality. This study first its kind explore a statistical approach determining optimum different parameters dataset. Furthermore, provides practical tools understand how frequencies representative changes.
