Sedimentological processes often result in complex three-dimensional subsurface heterogeneity of hydrogeological parameter values. Variogram-based stochastic approaches are often not able to describe heterogeneity in such complex geological environments. This work shows how multiple-point geostatistics can be applied in a realistic hydrogeological application to determine the impact of complex ...

In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by the scientists of Riga Technical University (RTU). LAMO comprises geological and hydrogeological data provided by the Latvian Environment, Geology and Meteorology Centre (LEGMC) for the active groundwater zone of Latvia. In 2013–2015, LAMO was notably upgraded. The number of HM layers and the density of hydrographica...

The scientific community has a growing interest in understanding the interaction of human-water system water resource models. In Santa Elena (Ecuador), Valdivia, San Pedro, Sinchal, Barcelona and Carrizal communities are located semi-arid area, making supply critical problem for local communities. addition to climatic conditions sector, main is weak participation integral management groundwater...

1. Latent EEects in a Hydrogeological Problem In the present study we investigate the data provided by the karstwater level monitoring system, set up in the Transdanubian Mountains, more precisely in the Bakony, the Keszthelyi Mountains and the Balaton-Highland. (Here, like in the sequel, the term karstwater is used for groundwater in karstic areas.) The detailed description of the monitoring s...

CO2 geological storage (CGS) is one of the most promising technologies to address the issue of excessive anthropogenic CO2 emissions in the atmosphere due to fossil fuel combustion for electricity generation. In order to fully exploit the storage potential, numerical simulations can help in determining injection strategies before the deployment of full scale sequestration in saline aquifers. Th...

Principal component analysis is applied to 309 groundwater chemical data information from wells in the Serra Geral Aquifer System. Correlations among seven hydrochemical parameters are statistically examined. A four-component model is suggested and explains 81% of total variance. Component 1 represents calcium-magnesium bicarbonated groundwaters with long time of residence. Component 2 represen...

8 Climate change is one if not the most pressing challenge modern society faces. Increasing temperatures are observed 9 all over the planet and the impact of climate change on the hydrogeological cycle has long been shown. However, so 10 far we have insufficient knowledge on the influence of atmospheric warming on shallow groundwater temperatures. 11 While some studies analyse the implication c...
