applications integrated on Geoportal such as a search metadata or a web map. WMS is
understood as a shared map, which can be used by the client's built-in GIS software such as
ArcGIS Desktop, Map Info, Quantum GIS. MDS is understood as available maps and forms
prepared for mobile devices equipped with GPS receivers and wireless transfer which
allows for sending measurement results via the Internet to ArcGIS Server. Moreover, the
results of the automatic monitoring stations are sent using the cellular network and the
Internet. This method of data communication becomes more important for the system and
can be used by workers, scientists and students working with the Park. Data sent by the
scientists and student is transferred to a separate database, which checks their legal status,
verifies and then introduces information to the main database.
5. Monitoring
Analysis of parameters obtained from water level and discharge monitoring, provide robust
and useful information on the physical stage of both water bodies and water-dependent
ecosystems. Hydrological and meteorological monitoring has been placed in Biebrza
National Park as an activity of special interest, indispensible for effective data-supported
management. Collected and processed data of groundwater and surface water level
dynamics are frequently applied in decision making processes (i.e. in issuing opinions and
evaluating impact of possible investments on ecosystems of the valley of Biebrza). The data
obtained from automatic and manual field measurements become also the key input to
hydrological models, which broad extent in particular basins of the valley allowed to
interpret the status-quo of ecosystems and to analyze certain scenarios of their development
in time and space. A hydro-meteorological monitoring network of the BNP was established
initially in the very first years of the Park functioning (1990ies) and then extended by
different scientific institutes conducting research in the Biebrza wetlands. As hydrological
processes play a siginificant role in the valley of Biebrza for wetland ecosystem
development, both surface water and ground water have been continuously monitored
since 1995 on numerous locations. The current monitoring network is primarily supervised
by the BNP, Institute of Meteorology and Water Management and Warsaw University of
Life Sciences staff. It consists of 25 surface water gauges, more than 120 groundwater
piezometers, three automatic meteorological stations and four rain gauges. Continuous
dataset from monitoring network can be additionally supplied with data collected within
the area of BNP by other scientific institutions. The monitoring network of the BNP, Warsaw
University of Life Sciences (WULS) and the Institute of Meteorology and Water
Management is presented in Figure 3.
Surface water monitoring and the rain gauge standard examination have been done
continuously in a 1-day time-interval, however for certain research purposes the surface
water network in the lower Basin is running with 6 hours interval, while in upper Biebrza
River automatic water level sensors are recording water levels with a 10 minutes interval.
Groundwater level measurements are being done in approximately 10-day time interval,
however in some locations automatic water level sensors have been installed in piezometers
and programmed to a measurement interval of 6 hours. Automatic meteorological stations
record parameters of rainfall, wind speed, air humidity, temperature and solar radiation
continuously, in 1 - 30 minutes time interval.
Data of hydrological and meteorological monitoring are being collected and delivered to
specialists responsible for data processing and storage by field services of the BNP and
WULS researchers.
