There are many new features that will make GV even more powerful. Here are the most important new features!

Import New MODFLOW2000 Files. Groundwater Vistas can now import existing MODFLOW2000 datasets for the SFR1, SFR2, HUF, ETS, DRT, and LAK3 Packages.

New Layout View. The layout view will show you what your plot will look like on a piece of paper, allowing you to customize headers, footers, legends, etc. Each figure will show up as a tab along the right side of the GV window. To see the figure, simply click on the tab. You can also embed charts, logos, and custom graphics in the layout..

Model Reports. A number of detailed reports can be written for calibration, mass balance, dry cell locations, etc. There are also custom reports in Microsoft RTF format where you can embed codes that are automatically replaced with descriptive information about the model. Run Log and Notes. GV5 can automatically create a run log every time you run your model. This report conforms with ASTM standards and can be customized by the user. You may also associate an external document with your Vistas design to record notes and observations about your modeling effort.

Huge Transient Runs. One limitation Vistas has had in the past is with large transient models. The problem as been the amount of memory required to store all of the recharge and ET data for each stress period. A new caching scheme now allows you to store this data on disk, making it possible to work on very large transient runs.

Custom Contour Levels. You may now define the specific contours you want for each data type (head, drawdown, concentration)

Easier Boundary Condition Editing. Vistas has always had the ability to perform complex edits of boundary conditions. Now there are additional tools for quick editing that is more intuitive.

Custom Output Control. There is more control over what to save and when in the MODFLOW output control file, including use of the new DDREFERENCE flag in MODFLOW2000/2005 which allows drawdown to be computed based on any time step GWM Optimization Model. GV5 continues to support SOMOS, MGO2003, Brute Force, and MODOFC. GWM is a new optimization model based on MODFLOW2000. GMS and Visual MODFLOW Import. GV has always been able to import GMS and VM runs but usually some edits needed to be made outside of GV prior to the import of these files. GV5 now simplifies the import of GMS and VM so that no editing is required.

Unsaturated Zone Flow (UZF) Package. MODFLOW2005 has a new runoff/recharge/et package tha includes the effects of flow through the unsaturated zone. GV5 fully supports the UZF Package.

Lake Spreadsheets. Data entry for the Lake Package has been simplified so that most data can be entered on spreadsheets. Drawing Elements. You may now draw shapes within Vistas to augment the digitized base maps. You may also import bitmaps such as charts and pictures to overlay on the model or on the layouts.

Change Boundary Types. Boundary conditions can now be changed from one type to another (e.g. change constant heads to rivers) on the fly.

Editing & Selecting Analytic Elements. There are many new ways of selecting analytic elements for copy/paste and delete.

New Analytic Elements. Polyline and polygon analytic elements have been added for use with most boundary types.
