Extreme events in the context of late Quaternary environmental change
The significance of extreme events in landform change is discussed in the context of the late Quaternary. Millennia-scale cycles of climate change are less than the relaxation times of most landform systems and have led to widespread disequilibrium
in natural landscapes. Slope failures and fluvial systems show parallel evolutionary trends in high and low latitudes, resulting from late Quaternary environmental changes. The transformation of geomorphic systems appears to require millennia of preparation
Past hydrological events related to understanding global change
This paper reviews recent changes in river management. These changes are characterised by a move from the notion of rivers as stable equilibrium forms to one of dynamic responsive ecosystems. Palaeohydrology is shown to be capable of providing

is observed in the forest-steppe and steppe zones. The roles of regional climate dynamics and land use change are confirmed by hydrological and meteorological data coupled with data on anthropogenic gully formation. Detailed studies of SND dynamics in a number
Past hydrological events related to understanding global change
A comprehensive database of radiocarbon dated fluvial units in Great Britain, Poland and Spain has been compiled to investigate the relationship between environmental change, flooding and Holocene river dynamics. Data analysis has been undertaken
hydrological events, as well as for predicting river response to future environmental change,is assessed.

Palaeohydrology and environmental change
the Subatlantic about 2100 and 1000 BP manifested themselves here by changes of the type of sedimentation on flood plains (buried soils). These phases are conditioned by the climate, altough in the younger one a remarkable influence of human activity is evident
To provide characteristics of present-day extreme events which may serve as a key to better recognition of past hydrological changes, the upper Vistula basin was taken as an example. The observations are mainly related to last 100-150 years
Past hydrological events related to understanding global change
This paper offers an alternative to the use of geomorphological and sedimentological evidence for the reconstruction of flood and low flow frequencies. It is based on a technique developed to estimate the hydrological impact of future climate change
Past hydrological events related to understanding global change
This paper is aimed at analysis of the palaeoenvironmental conditions and causes for the palaeohydrological changes, and palaeohydrological reconstruction in the Seim River basin since the Late Pleniglacial. The Seim River system drains the western

In Estonia, extreme events have been caused by meteorite explosions, earthquakes, and neotectonic processes, heavy storms, karst phenomena and human impact. Investigation of past processes provides a major key in predicting the changes that could

The longest instrumental rainfall series have been investigated for the North Assam subdivision and 4 meteorological stations in Northeast India. Analysis of trends to annual and seasonal rainfall show these to be very stable, with no change
