environment.

Schematically, it is shown in Fig. 9.6 . The user, through interface, sends per-
mission at each step of the command dialogue, which is assessed in the unit of the
query analysis, and from its response, the controlling unit realizes a chain of needed
actions of the system. Via return channels of query, the resulting prediction is
arranged in the needed form, which can change in each cycle of service. The nal

result is presented in the form of the protocol with enumerated characteristics of the
water environment by objects and territories as well as in the form of schematic
maps or digital information combined with the map.

9.2.1 Fresh Water Problems

The fresh water problems attract special attention, since, on the one hand, water is a
key component of ecosystems and, on the other hand, about 1/3 of the global
population is under the threat of chronic de cit of water in several decades. This

and other facts have determined the declaration of the UN Fresh-Water Decade
(2005

2015). The following facts characterize the present state of the global water
resources (WCSDG 2004; WB 2009):
