Investigations were carried out in the Pilica River valley between Inowłódz and Domaniewice. There are protrusions of the valley basement composed of Jurassic sandstones, as well as moraine deposits in the channel zone. They act as erosion resistant thresholds, resistant to the flood waters flows. The traces of the erosion and deposition of these flows exist on the floodplain surface, concealing traces of Holocene Pilica evolution.

This article presented evaluation of execution of water protection in Polish Environmental Policy. Improvement of water quality and quantity was a effect of improve water management system, partnership in water protection on borderland, regulation of payment and fine mulct in water protection and management, development of small retention, arrangement of water and waste water manage-ment, amendment of water law, co-operation between water management, national economy and ecological education. Positive result of execution of water protection in Polish Environmental Policy, were notice. However, classification of the state of uniform river bodies, showed that most of Polish waters were included to category poor. That's why Poland should proceed activities in water protection.

Paper presents some of results of remote sensing analysis, carried out in the middle Vistula River valley in the vicinity of Magnuszew. Study was carried out simultaneously with field geological setting of the floodplain and channel zone. The aim of investigations was recognition of the tendencies high water current concentration on the floodplain area and estimation the suitability of satellite photographs of high resolution in fluvial environment prognosis as well as mor-phogenesis model creation purposes. The investigations were carried out in the frame of the scientific project no. 2P04E06929 entitled "Significance of morpho-genetic factors in the development of habitat diversity of selected river valley stretches in the Polish Lowlands".

In May and June 2010 two extreme floodwaves inuduced by heavy rainfall in Carpathians Mts. have resulted in four levée breachs in mid-Vistula reach and one levée breach in lower reach of the Vistula valley. The basic outline of the flood was presented on the basis of data collected by Institute of Meteorology and Water Management - National Research Institute (IMWM-NRI): total precipitation, stage hydrograms from three water gauges with telemetric system and discharge. The field research was conducted on: all levée breaches were mapped by GPS. Morphology of sub-alluvial basement in the low-Vistula reach was mapped by drilling in the river channel (in the islands, sandy bars and river banks). The data obtained from our field research were compared to results of geological mapping of the river channel carried out in mid-Vistula reach before 2007 by other author. Using GIS-data base we juxtaposed all these data what has revealed adjacent location of all levée breachs to protrusions of sub-alluvial basement. The model of levée breachs process caused by piping in the low-Vistula reach was presented. The influence of the sub-alluvial basements on the underseepage process was discussed with emphasis on geological setting and geomorphology of the floodplain. ...
