About the Visual HELP Interface
Visual HELP utilizes a very 'flat' interface structure and innovative graphical tools to give you convenient access to both the basic and
advanced features of the HELP model. The result is a truly revolutionary approach to hydrological modeling that gives you more power and flexibility with your model profile than ever before. The interface is divided
into three separate views, the Project Tree View, the Profile View, and the Output View. When you open or create a project in Visual HELP, you will be able to seamlessly switch between these
views to build or modify the landfill design and model input parameters, run the simulations, and display results.

The Visual HELP Project Tree View
The Project Tree View displays the Visual HELP project you are working on, the names of each model profile, and
each layer in the active model profile. The Project Tree View acts as a project manager allowing you to easily
create and manage multiple model profiles within the same Visual HELP project. All model profiles for a project are
saved in the same database for easy access and handling of the model data and simulation results. The Project
Tree View also allows you to easily add layers, delete layers, edit layer properties and group multiple layers using standard Windows 95/98/2000/NT right mouse button operations.
The Visual HELP Profile View
The Profile View provides a graphical representation of the landfill profile and allows you to graphically modify the
layer geometry using standard 'point-and-click' and 'drag-and-drop' operations. The user can also add, delete, split or insert layers, or edit layer properties from the Profile View.
The Visual HELP Output View
The Output View allows the user to display all of the generated weather data and modeling results using a
comprehensive selection of graphical presentation formats. The display of data can be modified to choose daily, weekly, monthly or yearly results for the following simulated parameters:
- Precipitation, runoff and evapotranspiration
- Lateral drainage collected from selected model layers
- Percolation or leakance through selected model layers
- Average head accumulated on selected model layers
Each view of the Visual HELP interface can be seen from the main window as shown in the above figure.
