- E. Domains map: each domain class is represented by a 3-digits code: x y z
- x representing the relative permeability of the bedrock:
1: Low permeability, 2: Intermediate permeability, 3: High permeability - y representing the occurrence and permeability of the superficial deposits:
0: No deposits, 1: Low permeability, 2: High permeability - z representing the relative thickness of the superficial deposits:
1: 0–6.3 m, 2: 6.3–19 m, 3: >19 m
- x representing the relative permeability of the bedrock:
- F. Text: description of the general geographical and geological setting
- G. Geological log
Page 2:
- A. Groundwater level hydrograph, alongside with rainfall and recharge time series associated to the area containing the borehole
- B. Histogram showing the characteristics of the superficial deposits 1000 m and 2000 m from the borehole
- No : no superficial deposit
- H : high permeability superficial deposits, with increasing thickness (1–3)
- L : low permeability superficial deposits, with increasing thickness (1–3)
- C. Time series decomposition between Seasonality, trend and remainder (only daily time series)
- D. Text: interpretation of the hydrograph and the results of the decomposition
