Anionic: Have one or more negatively (-) charged groupings; commonly used in laundry detergent Cationic: Have one or more positively (+) charged groupings, typically poor detergents but well suited for use as germicides, fabric softeners and emulsifiers. Amphoteric: Contain both anionic and cationic groupings; prefer neutral pH and found in products such as hair shampoo, skin cleaners and carpet shampoo. • Ionic Surfactants make up >99% of the sufactant used around the world Non-ionic: Have no ionic...
Five principles of uncertainty for modelers discussed in November-December issue of Groundwater
If you’re a member of the NGWA Scientists and Engineers Section, you will soon receive your copy of the November-December 2017 of Groundwater®, an issue brimming with a wide range of topics. In his Guest Editorial, Randall J. Hunt offers five principles of uncertainty for groundwater modelers. He argues that uncertainty must be presented in a way that is easy to understand. Admitting there are many things we do not know will improve acceptance of the things we do know. Kelvin Wong and Marirosa Molina...
Modeling impacts of climate change and human activities on groundwater resources using MODFLOW
This paper analyzes the impacts of climate change and human pressures on Yazd-Ardakan aquifer using the Hadley Centre Coupled Model, version 3 (HADCM3) circulation Model and A2 emission scenario. Water levels in the study aquifer were simulated using three-dimensional finite-difference groundwater model (MODFLOW 2000) with GMS 8.3 as pre- and postprocessing software. Input for groundwater recharge time series under the climate change scenarios were derived using a regression equation based on the cumulative...
Solarpark Malching - Case Study
Operator: MONDAS Gründstücks- Verwaltungsgesellschaft mbHEnergy company: Stadtwerke FürstenfeldbruckLocation: Malching/Fürstenfeldbruck, GermanyCommissioning date: July 2009Completion time: 8 weeksRated system power: 4.732 MWp Making green energy To start with, feelings ran high in the village of Malching which is part of Maisach: people were worried about whether a solar plant, which covered 16.4 hectares and produced enough electricity to supply around 1,380 three-person households, would...
Optimal design of groundwater-level monitoring networks
Groundwater monitoring plays a significant role in groundwater management. This study presents an optimization method for designing groundwater-level monitoring networks. The proposed design method was used in the Eshtehard aquifer, in central Iran. Three scenarios were considered to optimize the locations of the observation wells: (1) designing new monitoring networks, (2) redesigning existing monitoring networks, and (3) expanding existing monitoring networks. The kriging method was utilized to determine...
