Therefore, new research on obtaining the optimal mixture of sucrose, 8-HQS, and citric acid, and building eco-friendly pretreatments and preservatives utilizing organic supplies really should be performed.Author Contributions: Conceptualization, I.-S.S. and H.Y.; methodology, I.-S.S. and H.Y.; validation, J.-H.L., S.L. and J.-W.C.; investigation, H.Y.; resources, I.-S.S.; data curation, J.-H.L., S.L. and J.-W.C.; writing–original draft preparation, H.Y.; writing–review and editing, I.-S.S. and H.Y.; visualization, H.Y.; supervision, I.-S.S.; project administration, I.-S.S.

Although compact fluorometers are becoming lighter and much more accessible [1], it is typical to work with 1 fluorometer per monitored location of a river. Most users are possibly aware from the importance on the positioning for the relevance of data. Certainly, as karstic rivers can have complex geometries, it appears intuitive to think about the position of your fluorometer an important factor for the tracer test outcomes. Because the geometry becomes complicated in karst environments, the classical velocity distribution across a river channel section is probably not applicable anymore, as many unique flow paths can occur. The presence of obstacles and side pools of variable dimensions is recognized to possess a significant impact on tracer test benefits generally [2]. Lateral and Salubrinal medchemexpress vertical heterogeneities in tracer distribution and breakthrough curves will not be effectively quantified. Research with the dispersion and retardation of tracers within the watercourses and side pools of karstic geometries have been performed in the past each by field tracing tests and fluid flow simulations [2]. Among those research, a single attempted to quantify the lateral heterogeneityHydrology 2021, eight, 168. https://doi.org/10.3390/hydrologyhttps://www.mdpi.com/journal/hydrologygy 2021, 8, x FOR PEER REVIEWHydrology 2021, eight,2 of2 offlow simulations [2].
