Notes: Variables: pool surface area (Area), perimeter (Peri), depth, degree of permanency (Perm.; p = permanent: the water level drops during summer, but water depth still remains more than half of the winter value; v = variable: the water level drops considerably during summer; t = temporary: the water level drops dramatically during summer and the pool can completely dry out), temperature (Temp.; the water temperature of an average pool ranges from 419°C over the annual cycle), pH, conductivity (Cond.), concentration of dissolved oxygen (D.O.), water transparency depth (Snell), chlorophyll a concentration (Chl a), concentration of total suspended solids (T.S.S.), N-NO3 concentration (N), total phosphorus concentration (TP), and the presence of submerged macrophytes (measured as Plant Infested Volume [P.I.V.] after one year of the pool's existence; 0: not present; 1: < 5% of pool volume; 2: 5% < x < 50% of pool volume and 3: > 50% of pool volume). Averages are taken over twelve monthly readings, except for morphometric variables (Surface area, Perimeter and Depth), for which only the mean value of the winter period is used, and nutrient concentrations, which are the medians of four (seasonal) measurements.
