SWMM5 Delphi GUI Daquifer.pas Summary

 The Daquifer.pas unit is part of the EPA SWMM (Storm Water Management Model) project and contains the form and logic for managing and editing groundwater aquifer properties within the software. The form allows users to view and modify aquifer-related parameters, which are used for simulating groundwater flow and interactions in the SWMM model.

Key Features of Daquifer.pas:

1. Form Controls:

   • Panels and Buttons:
     • Panel1, Panel2: Contain layout for form elements.
     • OKBtn, CancelBtn, HelpBtn: Buttons for submitting, cancelling, or accessing help.
   • Property Editor:
     • PropEdit1: A custom editor control (TPropEdit) for displaying and editing aquifer properties.
   • Hint Label:
     • HintLabel: Displays hints for selected properties.

2. Property Management:

   • Aquifer Properties:
     • The aquifer properties include name, porosity, wilting point, field capacity, conductivity, and others.
     • The AquiferProps array contains the list of all property labels, and DefaultProps contains their default values.
     • AquiferHint provides descriptions for each property.
   • Validation:
     • ValidateEntry: Ensures that each property field is filled out correctly.
     • ValidateInput: Checks if the aquifer name is valid and not duplicated.
   • Setting and Getting Data:
     • SetData: Loads the current aquifer property values into the form.
     • GetData: Retrieves the edited values from the form and updates the aquifer data.

3. Event Handlers:

   • FormCreate: Initializes the property editor and sets up the properties for the aquifer form.
   • FormShow: Displays the form with the current property values.
   • OKBtnClick: Validates the input and confirms the changes if valid.
   • HelpBtnClick: Opens the help for aquifer properties (via context help).
   • FormKeyDown: Allows users to press F1 for help.

4. Aquifer Property Definitions:

   • PropNames: Contains the names of the aquifer properties.
   • DefaultProps: Specifies the default values for these properties (e.g., porosity, conductivity, etc.).
   • AquiferHint: Provides a description for each property to assist users in filling out the form.

5. Aquifer Validation:

   • The form ensures that the aquifer name is valid (non-blank and unique).
   • If the user attempts to save the data with invalid input, appropriate error messages are displayed.

Purpose:

The Daquifer.pas unit is responsible for managing the aquifer properties in the EPA SWMM simulation. It provides a user-friendly interface for editing aquifer characteristics that are used to simulate groundwater behavior. The form includes functionality for entering aquifer data, validating input, and saving the changes, with error handling for duplicate or invalid entries.

In summary, this unit handles the interaction between the user and the SWMM system regarding groundwater aquifer properties, ensuring that the data is entered correctly and efficiently.
