Visual OTTHYMO 6.2

Visual OTTHYMO 6.2

Visual OTTHYMO is a comprehensive hydrological modeling software based on the widely-used OTTHYMO methodology, originally developed in Canada. Version 6.2 provides an integrated Windows-based environment for simulating rainfall-runoff processes, routing flows through drainage networks, and analyzing stormwater management measures. It combines the robust OTTHYMO engine with modern graphical interfaces for efficient urban hydrological analysis and design.

💧 Primary Users

Visual OTTHYMO is developed for hydrological engineers, urban drainage planners, municipal engineers, water resource consultants, and environmental regulators. It is specifically designed for professionals who need to model urban stormwater systems, analyze runoff, and design drainage infrastructure for flood control and water quality management.

✨ Key Features & Capabilities

• Integrated Hydrological Modeling: Complete implementation of the OTTHYMO methodology for simulating urban and rural watershed hydrology, including rainfall-runoff processes, infiltration, and evapotranspiration.

• Urban Drainage System Analysis: Model complex drainage networks including storm sewers, channels, ponds, and control structures with dynamic routing capabilities.

• Graphical Watershed Delineation: Visual tools for defining subcatchments, flow paths, and drainage networks using digital terrain data and aerial imagery.

• Climate & Rainfall Data Integration: Support for various rainfall data formats including synthetic design storms, historical rainfall series, and climate change scenarios.

• Water Quality Modeling: Capabilities for simulating pollutant buildup and washoff processes, supporting Best Management Practice (BMP) evaluation for water quality control.

• Scenario Management & Comparison: Tools for creating and comparing multiple design scenarios to evaluate different stormwater management strategies and infrastructure options.

• Comprehensive Reporting & Visualization: Generate detailed hydrological reports, hydrographs, and system performance metrics with graphical output for analysis and presentation.
