When: 2007-2008Where: A provincial capital city in Northern ChinaTeam: Beijing Rocktech Co. Ltd.Objective: ● Develop a water distribution system modelling system

using EPANET and ArcGIS Engine● Collect field data, create, calibrate and validate

EPANET model for the city

Project Overview

Roles and Responsibilities● Principle modeler to coordinate model data collection, field

survey and model calibration● Designed GeoDatabase for EPANET model and created the

Geodatabase from existing GIS system● Designed and developed the main interface with ArcGIS

Engine, VB.NET, DevExpress and ZedGraph● Test and deployed the system● Compiled user manual● Customer service and system maintenance

ArchitectureGUI/.NET

COM/ATL DLL

ArcGIS Engine

Model Geodatabase SCADA Database

Technology - User Interface

● ArcGIS Engine○ Basic map functions○ Customize symbology based on model results○ Network analysis and 3D analysis

● ZedGraph - for graph● DevExpress - most of the visual components● VB.NET

Technology - Modelling

● EPANET - water distribution piping system modelling library programmed with C

● COM/ATL DLL + Visual C++○ Read model data from Geodatabase through ArcGIS

Engine○ Run EPANET and provide interface to read results

● ArcGIS Engine for C++

Highlights

● Query and locate features● Edit features and attributes● Customize feature renderer to display model

results on map● Network analysis through Geometric Network● 3D analysis through TIN
