Welcome to IAMDD

Welcome to the IAMDD (Integrated Agronomic & Municipal Demand Dynamics) user manual.

IAMDD is a next-generation, web-based hydraulic modeling platform designed to bridge the gap between traditional civil engineering, modern agronomy, and spatial analytics. Built on top of the robust EPANET hydraulic engine, IAMDD introduces dynamic, weather-responsive demand modeling for both agricultural operations and municipal water networks.

Whether you are designing a new pressurized irrigation district, optimizing a municipal water grid, or evaluating the financial impacts of rotational water rights, IAMDD provides the tools you need to model your system exactly as it operates in the real world.

Core Capabilities

• Spatial Network Design: Draw your pipes, nodes, and demand areas directly on an interactive GIS map. IAMDD's intelligent topology engine automatically handles node snapping, pipe splitting, and length calculations in real-time.
• Dynamic Agronomic Demands: Stop guessing your base demands. IAMDD pulls live soils data (SSURGO) and tracks the daily Soil Water Balance using actual evapotranspiration (ETo) to trigger irrigation events exactly when the crops need them.
• Automated Municipal Peaking: IAMDD calculates residential indoor demands based on localized building footprints (OpenStreetMap) and automatically scales outdoor sprinkler use based on real-time weather data.
• Rotational Scheduling: Enforce complex administrative water rights. Define rotational intervals, durations, and offsets to physically lock headgates and prevent deliveries when a field is off-schedule.
• Energy & Financial Modeling: Evaluate your true operational costs. IAMDD integrates Time-of-Use (TOU) energy rates and monthly peak demand charges directly into the hydraulic simulation.
• Scenario Management: Build "What-If" alternatives without destroying your baseline data. Instantly compare the hydraulic performance and energy costs of multiple scenarios side-by-side.
