Using Grid Tools in the RockWorks Utilities to Modify a Borehole Manager Stratigraphy Model
SummaryCreating a geological model with RockWorks can be tricky with certain datasets. When a Stratigraphy Model is created in the Borehole Manager, the program creates a top and base grid for each unit listed in the Stratigraphy Table. After model generation, you can view these grids, stored in the Project Directory, in the RockWorks Project Manager. The following steps demonstrate how you can use Grid Math and the Polygon Filter to modify the grids for the uppermost unit (the A-Horizon, displayed in green) so...
Groundwater quality changes in a groundwater body in a poor chemical status
The chemical composition of groundwater in the Quaternary body SK1000600P in the Danube basin was analysed based on chemical analyses from 7 monitoring sites of the Slovak Hydrometeorological Institute network during 2002–2009 and 2010–2015 time periods. The current status was evaluated based on the Regulations of the Government of the Slovak Republic No 282/2010. The influence of the pollution point sources on the groundwater quality was analysed based on selected indicators and their threshold values. The most...
Radon-222 from different sources of water and the assessment of health hazard
Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% being higher than the threshold value of 11.1 Bq.L−1 recommended by the USEPA. The mean annual effective dose (AED) due to...
Assessment of sustainability of rural water supply services in Tanzania: the case study of Dodoma ...
Rural water supply services in Tanzania are still inadequate. Despite the substantial resources invested to provide safe water, there is a significant number of water points that are non-functional. Knowledge of the degree of sustainability and the contributing factors for rural water supply projects is limited. This study employs the fuzzy set concept to assess the degree of sustainability of water points in seven Local Government Authorities (LGAs) of Dodoma region in Tanzania. Dodoma region lies in the semi-arid...
