| − | COSH-Tool can be applied to any water level or discharge time series provided by measurements (field work) or simulation (numerical modelling). The analysis of the time series with COSH-Tool does not require any coding from the user and is executed through an interface.

| − | COSH-Tool computes a set of parameters that characterise water level and discharge fluctuations. The parameters can be classified in three categories: 1) magnitude of the variations; 2) timing and rapidity; and 3) frequency. The parameters are listed in Table 1.

| − | The output from COSH-Tool consists in a table with statistics of the magnitude and timing parameters (category 1 and 2) and a set of graphs of corresponding graphs. Statistics are min, max, mean, median, standard deviation and percentiles. They can be computed for the entire time series, as well as on a monthly, seasonal and yearly basis. Statistics are also displayed in the form of box plots.

| − | COSH-Tool provides also values and graphs for all frequency parameters (category 3), namely distribution of peaks throughout the day (Figure 2), number of peaks per day for each year of the time series (Figure 3), and total number of peak events per year.

| − | Additionally, the light conditions (day, twilight, darkness) at the time of the occurrence of the peaks can be computed. A graph provides the proportion of peaks occurring at the different types of light conditions per month (Figure 4).

Introduction
Visible Implant Elastomer (VIE) Tags are coloured tags (https://www.nmt.us/visible-implant-elastomer/). They are implanted in translucent tissue of several animals, mainly used in fish, but also in crustaceans, cephalopods, reptiles, amphibians, small mammals, etc. (Figure 1). VIE consists of two liquid components (colour component and curing agent) which are mixed just before the tagging, changing into a solid state in a short time (1-2 hours). VIE are injected subcutaneously with syringes or specialist injection systems in clear tissue areas, and there are several colours available, with and without fluorescence.
