On the basis of measurements of hydrological parameters and field monitoring of a landslide in the Terres Noires in the basin of Barcelonnette, a hydrological model was developed, describing groundwater fluctuations in relation to precipitation
. These groundwater fluctuations can be used as input to a stability model in order to assess the temporal frequency of instability of the landslide. The calculated groundwater fluctuations, which can forecast years with landslides incidents, were roughly calibrated
Maximum recessions of shallow groundwater level in central Poland

This paper presents a method of describing maximum recessions of groundwater level, drawing on an analysis based on data gathered from 41 sites, between the rivers Warta and Vistula, for the monitoring of groundwater level. Maximum weekly recessions
for all of the measurement points were selected, before being employed as a basis for approximating the regression lines used to calculate the theoretical top speed recession curves between maximum and minimum groundwater levels, and the estimated time
needed for such a recession to be achieved. Sudied characteristics of all the examined groundwater recessions were compared with geographical characteristics of the aquifers involved, in order that relations between them could be determined.

The effects of the changed hydrological conditions on 5 palsas were monitored over a period of 5 years. All the palsas increased in height. A core through one palsa showed that while it was formed by segregation ice, the observed height increases
Estimations of the past groundwater recharge rate from deep borehole temperature data
Paleoenvironmental records as indicators of climate and hydrologic change
Purposes of this study are to evaluate both effects of surface climate change (due to global warming and urbanization) and groundwater flow on subsurface thermal regime, and to estimate the past groundwater recharge rate from deep borehole
Most forest hydrologists agree that deforestation leads to augment groundwater recharge and dry-season flow but in the semi-arid tropics people state the very opposite. This paper presents a model which attempts to suggest not only that both
opinions in groundwater response to deforestation are correct, but also that they complement each other if the diversity in land management, hydroclimate, and landscape characteristics are taken into consideration. The possibility of closing the dichotomy

Relationship between Quaternary history and groundwater in the IJselmeer area in Developments in physical geography. A tribute to J. I. S. Zonneveld..
Concentration of salt ions in groundwater bearing Quaternary sediments in the IJsselmeer area have been changed by different processes such as transport, diffusion and dispersion, and the exchange of dissolved and adsorbed ions. Two case studies
at Oostelijk Flevoland, the IJsselmeerpolder which was drained in 1957, illustrate how the predominating process alternated, in relation with the geological and hydrological configuration and with human interference.
This paper deals with the geochemistry of the lakes and groundwater in the context of Holocene hydrological and climatic changes. The AA. firstly aim to establish comprehensive data sets of the ion chemistries of the waters contained in these lakes
on the basis of chemical analysis of water samples. Secondly, they study the recharge mechanisms of these lakes by comparing the lake water with the groundwater. Thirdly, they focus on analyzing the evidences of the Holocene climatic changes, in particular
