The electroneutrality principle is a very useful principle and one of the foundations of water chemistry. This principle states that the sum of positive and negative charges within the water […]
Electroneutrality (E.N.) is a powerful tool to find errors in major ion analyses. Histograms are an efficient way of presenting and reviewing E.N. values. A histogram divides the active data […]
A fundamental assumption when analyzing a pumping test is that the water level measured represents the water level in the aquifer. This is mainly true in observation wells, but not […]
Visual MODFLOW is often used to model the groundwater conditions at mine sites. These models are intended to assist in the decision making process for issues that are controlled or […]
Accurate numerical simulation of the movement of dissolved chemicals (solutes) in groundwater requires definition of chemical properties such as dispersion, sorption and species parameters; as well as identification of transport […]
On Wednesday, October 1st, we hosted a free 1-hour webinar on Visual MODFLOW Flex. The webinar was presented by Wayne Hesch, Senior Product Champion for Visual MODFLOW, and included a […]
The new particle tracking program mod-PATH3DU, developed by S.S. Papadopulos & Associates, provides a vital component for interpretation and analysis of MODFLOW-USG groundwater models. This program will be integrated into Visual […]
Last month we hosted a free 20-minute webinar on the new release of Hydro GeoAnalyst – our all-in-one environmental data management, analysis and visualization software. The webinar was presented by […]
In 2013 Visual MODFLOW Flex demonstrated the power of MODFLOW-USG through the use of Voronoi polygon unstructured grids. By focusing the grid resolution “where it counts”, you can achieve higher accuracy and […]
With the release of Visual MODFLOW Flex, we introduced a new streamlined approach to building groundwater models. Along with the traditional numerical modeling approach, we provided groundwater professionals with the option […]
