OpenFlows WaterGEMS 250 Pipes
A hydraulic modeling application, WaterGEMS provides you with an easy-to-use environment to confidently analyze, design, and optimize your water distribution systems. With advanced interoperability, geospatial model building, optimization, and asset management capabilities, WaterGEMS supports your engineering workflows from fire flow and water quality analysis, to energy consumption and capital cost management.
- OpenFlows FlowMaster
-
OpenFlows FlowMaster
You can efficiently use this calculator in the design and analysis of dozens of element types, such as pressure pipes, open channels, weirs, orifices, and inlets. Replace the error-prone spreadsheet process and switch to FlowMaster for reliable calculations on a wide variety of hydraulic elements.
- OpenFlows SewerGEMS 250 Pipes
-
OpenFlows SewerGEMS 250 Pipes
An easy-to-use advanced engineering software, SewerGEMS allows you to analyze, design, and operate sanitary and combined sewer systems. You can decrease decision risks by ensuring that the model uses the best available data, built-in hydraulic and hydrology capabilities, and a variety of wet-weather calibration methods. Easily create what-if scenarios to gain a better understanding of wastewater systems to make smarter decisions, and you can improve your response times. SCADA integration provides you with reliable model results, improves capacity and limits sewer overflows. This enables you to comply with sewer regulations set by regulatory agencies.
- OpenFlows CulvertMaster
-
OpenFlows CulvertMaster
An extremely powerful and easy-to-use calculator, you can use CulvertMaster to design and analyze existing culvert hydraulics. You can analyze everything from single-barrel crossings to complex embankment cross-drain systems, with different shapes and sizes, special tailwater considerations, and roadway overtopping considering watershed data, culvert characteristics, and even weir geometry. Select from a library of standard culvert shapes, materials, and entrance conditions, then compute culvert headwater and tailwater elevations.
