Narwiański Park Narodowy to jeden z 23 parków narodowych znajdujących się na obszarze Polski. Mają w nim miejsce wyłącznie szlaki wodne, natomiast szlaki piesze i wodne znajdują się na terenie jego otuliny. Przepływająca przez NPN rzeka Narew jest wyjątkowym ciekiem wodnym, gdyż płynie ona licznymi rozdzielającymi i łączącymi się korytami. Jej dolina, to miejsce ostoi ptaków wodno-błotnych objętych Europejską Siecią Ekologiczną Natura 2000. Edukacja i turystyka w Narwiańskim Parku Narodowym zajmuje wysoką pozycję. Znajdują się tutaj bowiem liczne szlaki turystyczne, jak i ścieżki edukacyjne. Dolina rzeki Narew kształtowana jest bowiem nie tylko przez naturę, ale i przez działalność człowieka.

The Narwianski National Park is one of the 23 national parks of Poland. There are only waterways in the National Park. Walking trails and waterways are located in lagging of this park. The Narew is unique watercourse, because it flows numerous separating and conecting riverbed through Narwianski National Park. The Narew River Valley is place of water birds stand covered by the European Ecological Network Natura 2000. Education and tourism in the Narwianski National Park occupies a high position. There are numerous hiking and educational trails. The Narew River Valley is shaped not only by nature, but also by human activity.

Celem pracy jest porównanie położenia zwierciadła wody w części doliny Narwi przed regulacją jej koryta 1966 r. oraz po regulacji w 1993 r. i 2012 r. Dotyczy to dolnej części Narwiańskiego Parku Narodowego i niżej położonej strefy buforowej. Na tym tle przedstawiono problematykę gospodarowania wodą w tym rejonie, uwzględniając zarówno potrzeby ochrony środowiska, jak i częściowe użytkowanie doliny w strefie buforowej. Analizowano wyniki pomiarów w piezometrach, na wodowskazach oraz z wykorzystaniem profesjonalnego odbiornika GPS. Poziomy wód przedstawiono w postaci map hydroizohips oraz w wybranych przekrojach. Mimo zastosowania różnych środków zaradczych ograniczających niekorzystne oddziaływanie uregulowanego odcinka rzeki na obszar Narwiańskiego Parku Narodowego, nadal występują trudności z utrzymaniem wysokiego poziomu wód gruntowych, szczególnie w okresach braku opadów. W pracy podano zakres niezbędnych działań technicznych warunkujących osiągnięcie stabilizacji warunków wodnych. Najważniejsze jest utrzymanie piętrzenia na jazie Rzędziany na rzędnej 110,70 m n.p.m., najlepiej przez cały rok, oraz wykonanie dodatkowych progów piętrzących między jazami Rzędziany i Babino.

The aim of this study was to compare the variations of water table level in part of the Narew River valley before the river bed regulation in 1966 and after regulation in 1993 and 2012. The study covered the lower part of the Narwiański National Park and its buffer zone. Measurements were made in piezometers and water gauges and with the use of professional GPS device. Water table levels were presented on maps of hydro isohypses in selected cross-sections. Despite implementation of various measures to limit negative impact of the regulated river section in the Narwiański National Park, it is still difficult to maintain high ground water table level, particularly in rain-free periods. Problem of water management in the region was outlined in relation to necessary fulfillment of the environmental protection and land use requirements in particular parts of the buffer zone. The scope was defined of necessary technical measures that need to be implemented to stabilize water conditions. Maintaining water level at Rzędziany gauge equal to 110.70 m a.s.l., preferably for the whole year, and construction of additional barrage between Rzędziany and Babino are the most important tasks for the future.

As GIS is becoming more and more popular and available for its users it finds new implementation in many fields of knowledge and areas of life and business. It is now used in government, research Institutes, Universities and by private companies. Geographic Information System stand by remote sensing is more often used in monitoring and researching Environment. Testing GIS and remote sensing to actualize and preparing maps gave very good effects. That was the reason for using this solution for shape researching and creating geomorphological maps. The purpose of research was to create detailed geomorphological map of Narew National Park and its buffer zone in scale 1:25 000 using remote sensing (spectroscopy images), GIS programs, available maps and fi eld research carried out in the National Park. Narew National Park is located in Podlaskie Voivodeship, in North-Eastern Poland, traversed by the Narew River. The total area of the Park is 73.5 square kilometres of which only 20.57 km² is state-owned. Narew National Park was created in 1996. The area covered by the park is the Upper Narew Valley, a very swampy area. The methodology of map preparation was composed from 3 stages: Stage 1 – introductory geomorphologic sketch Stage 2 – preparing geomorphologic map in scale 1:25000 Stage 3 – Composition of map – preparing for printing The methodology of research didn’t include stereographic images. The alternative solution was interpretation of mosaic of spectroscopy images putted on DTM with 10 times superiority. Superiority was essential because height differences on the research area are rather small (only 50 m between the highest and the lowest point). The interpretation of boundaries between forms was carried out on DTM products, which were: hypsometric map, slopes and shaded relief. New solution was also the usage of color infrared images which was until this research used only in investigating plants and their diseases and also in hydrology. Interesting solution was the development of photointerpretaion key in which 3-D images were used (generated from DTM). This was great opportunity to visualize shape and spatial relation between geomorphologic forms. It was also very helpful in stating the origin of the forms. What is more authors examined new form of presenting geomorphologic content. The impression of mallable picture was achieved by putting geomorphological map on the image of slopes, generated from DTM. After the research few conclusions were made. 1. Color infrared images are very useful in relief exploration, mainly because: convex form, in which water table is deeper, are brighter on the satellite image than concave forms, in which water table is lower, emphasis of the shadow is very useful for distinguishing excavation, the absorption of infra-red radiation by water caused that every water body is very well seen, for example water in Narew riverbed, oxbow lake and other lakes. 2. DTM and maps which can be generated from it can replace topographic map and long and expensive terrain studies. 3. GIS offers programs which are useful not only in map preparation but also in the process of its composition. Literature studies and presented research lead to the statement that relief of researched area was formed in the close of Wolstonian Stage (in Polish: Zlodowacenie Środkowopolskie) and it was denudated in latest time of Pleistocene and Holocene.

The aim of making the inventory is to describe the character and the scale of changes that occurred in the exploitation of land use within the boundaries of Narew National Park and its surrounding between 1987-2005. We made maps of land use in 1987 and 2005 based on cartographic materials, air photos, described data and statistics available. The research has been done for the area within the borders defi ned by the map of land use made for the year 1987 in Department of Geoinformatics and Remote Sensing Faculty of Geography and Regional Studies, Warsaw University. The map for the year 2005 has been made on the basis of the updated ortofotomap of Narw National Park and its surroundings. This maps was defi nited by legend elaborated by scientifi c staff under J. Kostrowicki from Polish Academy of Science at 1962 and still it is the best legend for and use maps at this scale.
