Drainage & Hydrology

S&B Infrastructure offers extensive experience with drainage master planning and design, 
erosion protection, hydraulic analysis and modeling, flood warning systems, canal and channel design, and construction management. 

S&B has multiple dedicated drainage modeling centers equipped with the latest and most advanced hydrologic and hydraulic analysis software and tools available. These include, but are not limited to, AutoCAD Civil 3D, HEC-RAS 2D modeling, HEC-HMS, Innovyze Infoworks, EPA SWMM and Bentley CivilStorm. Combining these tools with the latest Atlas 14 Texas rainfall data, LIDAR technology and  GIS, new geo-referenced models can be created to show high-resolution animations of actual historical flood events based on historical rainfall data. Also events likely in the future, based on a proposed fully-developed land-use condition. The result: a timely, cost-effective and more accurate way to create electronic solutions and databases for flood-prone areas, as well as a sophisticated modeling system that can be modified and grow with the new infrasturcture, a FEMA-preferred design method.
