    1. Fig. 7.2

      The soil moisture to evaporation arrow in fact includes transpiration and soil evaporation.

      Similarly interception evaporation and open water evaporation from the depression is not highlighted as process. We should think about including this (in correspondance to previous chapter). @Pierre, let's discuss before making changes.

    2. Infiltration

      Infilitration I (In case we are looking at short timescales infiltation is a loss, yet for longer timescales infiltration is only a loss if evaporated by transpiration or soil evaporation, but it is not a loss in case it recharges the groundwater and contributes to baseflow)

    3. If there is a quick response groundwater component, infiltration replenishes soil moisture and raises the groundwater level.

      delete sentence, I think this only leads to confusion

    1. Fig. 3.5 Discharge patterns of the Rhine and Meuse rivers.

      Onderliggende gegevens? Python code voor de plot? Misschien wel aardig om ook het 10e en 90e percentiel te geven

    1. 7.2.4.4. Minimum discharges# When analyzing minimum discharges, a log-Gumbel distribution is used instead of a Gumbel distribution. The precise properties of this distribution are not discussed here.

      This only adds confusion, may be entirely delelted.

      swop formula of R and A.

      After formula of R, the following text: For an idealized cross section, it holds that:

      A = ... and P = ...

      Moreover, I would like to see Figures 8.9 and 8.11 from the old lecture notes 2022-2023 back that illustrate the cross-section.

    2. a) What is the return period corresponding to an exceedance probability of 99%? b) Determine the annual maxima and rank them from highest to lowest.

      the answers to exercise 7.4a and b should also be done with Python code

    1. Fig. 1.1 Fieldwork at the river Alzette, Luxemburg.

      It feels a bit contextless to have this figure. Maybe better to remove this figure to 1.1 and not have figure here at all

    1. Aerial Photo of Mountain Under Cloudy Sky ()

      replace with:

      Hydrology is the study of the water cycle in diverse landscapes. Engineer hydrology deals with the quantification and management of water resources and civil engineering infrastructure such as dams and reservoirs (Photo by REFERENCE).

    1. Runoff coefficient to reflect the ratio of rainfall to surface runoff

      actually this should be ratio of surface runoff to rainfall (so the other way around). Also adjust in the text.
