9.1.1 Principal Matters
Risk of losses resulted from human factors, inadequate or failed internal processes
and systems, or external events is closely connected with aftermath weakening of
the damage reduction. This problem is important when stressful hydrophysical and
hydrochemical processes occur. For example, the control and assessment of the
state of the water environment require knowledge of numerous characteristics,
which can be classi
ed into:
(1) factors of the water chemistry;
(2) water quality; and
(3) dynamical characteristics.
first group includes characteristics of the processes affecting the water
quality and determining the dynamics of the parametric space that describes the
complex state of the studied aqua-geosystem. Depending on the experimental
conditions, these factors are connected with the spatial scale and can be point wise
or of areal character.
