Funcionalities - Giswater/giswater_dbmodel GitHub Wiki

Dedicated to the integral management of the water cycle, GISWATER is a free plugin that communicate the EPA’s water simulation software EPANET and SWMM, to a Spatial database using the Geographic Information System (GIS) interface of QGIS. This plugin goes beyond water modelling, and allows other functionalities, such as:

  • Inventory of all elements of the network.

  • Registration of visits and events (operational data).

  • Automatic network modification.

  • Flow direction analysis.

  • Linking documents and images to the network system.

  • Application of the hydraulic model.

  • Planning and equity value.

  • Possibility of linking to SCADA (Supervisory Control and Data Acquisition) systems and establishment of remote control of the water network infrastructure.

GISWWATER PROCESS Below is an inexhaustive list of various features found in GISWATER, with more being added in every release: Giswater Features

Basic tools:

  • Info: enables the user to check data that refers to the ud/ ws elements of the inventory (nodes, arcs, connecs and gully) and operational information (visits) without the need of having the layer activated

  • Select: enables the user to filter the plotted information on QGIS canvas based on different kind of criteria: exploitation area (Expl.), State, Hydrometer (ws schemas), Psector, Sector

  • Research tool: enables the user to do advanced searches based on 5 criteria parameters (network type, address, hydrometer, workcat, psector)

Administration tools:

  • Toolbox: Contains some (1) operation and maintenance tools (om); (2) edit tools that are able to verify topological consistency of the network (edit); (3)EPA tools that makes possible a previous check if the network is properly set for running as an EPA model (epa); (4) master tools (commands that makes possible check data consistency previously a first budget).

  • Configuration tool: enables the use set some default options for the project

  • CSV import: enables the user to insert external data into the data base, as for example, “.inp” data for the hydraulic model or prices information for financial forecast in planned sectors (psectors)

  • Fast print: enables the user to print in a fast way the canvas map showed at the moment.

  • Edit check: Enables the user do an audition of critical modelling errors, EPA warnings and complementary information (INFO) that orientates the user about the founded consistencies linked to the network’s elements.

Network tools: They were created to represent in an easier and faster way the constant changes on the network. Furthermore, enables the users to keep a historical track of all of those changes. Ws schema and Ud schema network tools are the same, just as showed below:

Add node/ Add Link/Replace Feature/ Arc divide/ Arc Fusion/ change node type/connect connecs and gullies to the 
network/ End feature (state type change)/ Delete Feature (no history tracking)/dimensioning/Add document/ Document 
Management/Add Element/ Element Management

O&M tools: Operational and maintenance tools differ upon it is a ws/ud schema. They are meant to keep a historical and geographic control of visits, as well as have the control of distinguished points of the network that can be affected or a related to some region of interest

  • Ws schema:

    Mincut/ Mincut Manager/ Add Visit/ Visit Manager/ Date Selector

  • Ud schema:

    Flowtrace (upstream)/ Flowtrace Exit (downstream)/ Profile tool/ Add Visit/ Visit Manager/ Date Selector

CAD tool bar:

Create Circle/ Create Point

Epa Tools:

  • Go to Epa: To generate .inp files and import . rpt files

  • Epa result manager: Enables the user to visualize all simulations in a table

  • Epa result selector: Enables the user select to of the simulations to be shown in the QGIS canvas for a fast, dynamic and intuitive comparison

Financial Planning tools:

New psector/Psector manager/Network cost management

Ps: psector are planification sectors that represents areas with planned actions (state 2 = planned) would affect different elements represented in the QGIS map. Through then, it is possible to obtain the execution price of the entire work, as well as the detailed prices of each element.
