Shallow foundations are often situated on unsaturated zones above the groundwater table. In this study, the influence of rainfall infiltration on the settlement behavior of shallow foundations was investigated using numerical analyses. The numerical solutions were compared with experimental data from in-situ load tests. The relative importance of rainfall intensities and groundwater table posit...

The effectiveness of shallow groundwater areas to serve as a sink for NO3 is affected by many biological and physical properties. However, the direct impact of these properties on the fate of NO3 in shallow groundwater is not well understood, especially where the soils are intermittently saturated. This study was conducted to assess in situ reaction and transport of NOa-N in an intermittent sha...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

18 Groundwater contamination was characterised using a methodology which combines 19 shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a 20 statistical framework and hydrogeological techniques. Nitrate-N (NO3-N) 21 contaminant mass flux was calculated across three control planes (rows of 22 piezometers) in six isolated plots. Results showed natural attenuation occu...

Article history: Received 11 July 2012 Accepted 15 January 2013 Available online 7 February 2013 Editorial handling by Peter Birkle Groundwater chemistry and isotope data from 44 public supply wells in the Napa and Sonoma Valleys, California were determined to investigate mixing of relatively shallow groundwater with deeper hydrothermalfluids.Multivariate analyses includingCluster Analyses,Mult...

The natural acidification of groundwater in some types of environment has accelerated by acid atmospheric emissions and cultivation during the last 200 years. The direct effects are seen in changes of the groundwater chemistry in four stages, (1) seasonal depression of pH, alkalinity and some cations in very shallow groundwater, (2) long-term increase of calcium, magnesium, nitrate and sulphate...

Abstract Deep groundwater monitoring in tight bedrock is not commonly performed and rarely documented. For a case study Bochum, NRW, deep wells allow investigation the outcropping Carboniferous down to depth of 186 m. Groundwater was carried out by combining sampling local springs at site. Inverse models were developed using hydrogeochemical code PHREEQC understand natural geochemical processes...
