FAQ
What information do you need to start?
Useful information includes survey/topographic data, site plans, CAD or GIS files, drainage information, rainfall data, watershed information, project requirements, and applicable design criteria.
Do you provide flood and floodplain modeling?
es. I can perform hydraulic flood modeling and analyze water surface elevations, flow behavior, inundation areas, and related flood conditions when sufficient project data is provided.
Can you review an existing hydraulic or drainage model?
Yes. I can review existing models, identify potential issues, check inputs and outputs, and provide technical recommendations for improvement.
Can you design detention or retention pond systems?
Yes. I can assist with detention/retention pond analysis, storage calculations, inflow/outflow assessment, and related stormwater management design.
Can you work with Civil 3D, CAD, GIS, and terrain data?
Yes. I can work with CAD drawings, Civil 3D files, GIS data, DEMs, topographic surveys, terrain models, and other relevant engineering data.
Can you model culverts, channels, and open waterways?
Yes. I can analyze culverts, channels, bridges, open-channel flow, and other hydraulic structures depending on the available project data.
Can you analyze existing drainage problems?
Yes. I can review existing site information, drainage networks, terrain, flow paths, and hydraulic conditions to identify potential drainage or flooding issues.
. Do you work with HEC-RAS and HEC-HMS?
Yes. I can provide HEC-RAS hydraulic modeling and HEC-HMS hydrologic modeling for applicable stormwater and flood analysis projects.
Can you create 1D and 2D hydraulic models?
Yes. I can develop and analyze 1D and 2D hydraulic models for channels, rivers, drainage systems, floodplains, and surface water flow.
