There is a well-known fable about a wood cutter who was hired by a timber merchant to cut down trees. This well sought-after job paid well and had excellent working conditions. The wood cutter wanted to succeed in his new job so the first day he worked hard and cut down 18 trees. Determined to do even better on the second day, the wood cutter tried harder but only cut down 15 trees. Day after day the wood cutter tried harder and harder but cut down fewer and fewer trees. Eventually, his boss came to him and told him that he was fired. The wood cutter was upset but knew he had worked as hard as he could so he reluctantly returned his axe.

Visual MODFLOW Flex Pumping Wells
The Waterloo Hydrogeologic software development team is constantly making improvements based on the feedback and suggestions from our worldwide users. Recently, our focus has been on redesigning the pumping wells boundary condition in Visual MODFLOW Flex. We chose to emulate the behavior from Visual MODFLOW Classic which provides a natural approach of defining the well discharge rate over the entire screen interval, and independent of the numerical grid. With this “conceptual” approach, a single well can contain multiple screens, fully penetrating screens, or partially penetrating screen intervals over the depth of the wellbore.

As mentioned in my previous blog post, 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 into ranges and plots the number of points (i.e. samples) in each range.

Visual MODFLOW Groundwater Modeling Course
SWS distributor, Beijing Water International (BWI), successfully hosted their fourteenth short course featuring Visual MODFLOW from November 12-15, 2014. This course was held in association with State Environmental Protection Engineering Center for Industrial Contaminated Sites and Groundwater Protection (E3), Peking University, China University of Geosciences (Beijing) and SWS. The course was attended by thirty participants from a wide variety of corporations and academic institutions throughout China.

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 in the pumping well (PW) itself.
The water level measured in a pumping well is not the water level in the aquifer.

Last week, environmental professionals from across the globe came together for a free webinar on the new features and capabilities available in Hydro GeoAnalyst 2014.2 - the latest release of our environmental data management and visualization software. New features include faster data importing, support for importing image files and improved reporting with Microsoft Office. In addition to covering new features, the webinar also provided an overview of key highlights from past releases including mobile electronic data deliverable, online data sharing with Hydro GeoAnalyst Online, and the easy-to-use Template Manager.
