Geochronometria
2007 Vol. 26 35-38
EN The fallout radioisotope 137Cs is widely used to study rates and patterns of soil redistribution. This method requires the knowledge about the initial fallout of cesium in the study area. This paper describes the method of establishing the initial fallout of cesium for a study area which is contamin[...]

EN Rainfall-runoff is the active agent of soil erosion which often resulted in land degradation and water quality deterioration. Its aggressiveness to induce erosion is usually termed as rainfall erosivity index or factor (R). R-factor is one of the factors to be parameterized in the evaluation of soil[...]

PL W pracy wyliczono masę erodowanej gleby dla warunków Puczniewa (woj. łódzkie). Do obliczeń wykorzystano roczne maksymalne dobowe sumy opadów z lat 1972-2002. Wykonano test Kołmogorowa- Smirnowa, aby ocenić zgodność danej cechy z rozkładem normalnym, następnie opracowano dystrybuantę rozkładu prawdop[...]
EN The mass of eroded soil was calculated for the conditions prevailing in Puczniew (Poland). Annual maximum daily rainfall from the years 1972-2002 was used for calculations. Kołmogorow-Smirnow test was used to check the distribution of a given characteristics and then the probabilisty distribution wa[...]

PL Rozmycia są najczęstszą przyczyną awarii mostów i powinny być monitorowane. Monitorowanie ma obecnie ograniczone możliwości i nie zapobiega awariom. Jest wiele przyrządów do monitorowania , w tym przenośne, stałe i geofizyczne, jak również wiele rodzajów instrumentów pomiarowych od tradycyjnych do s[...]
EN Soil erosion is most often reason of bridge failure and it should be monitored. Monitoring has now limited possibility and does not eliminate bridge failure. There are many types of devices for monitoring including mobile, stationary or based on GPS system, as well as measurement instruments. System[...]
