With expertise in Hydraulic Modeling, we are looking for challenging projects that require advanced applications of 2 or 3 dimensiional modeling. H2Flo Consulting is an experienced at field data collection and as a user of SRH-2D and TuFLOW for 2D hydraulic modeling in steady and unsteady flow conditions. In addition, for complicated non-hydrostatic conditions such as around bridge piers, we are skilled at using the CFD toolbox, OpenFOAM for determining forces and the detailed 3-dimensional flow pattterns.
A 2-D Hydraulic Model was developed to estimate the flow velocities during the ebb and flood tides for Monsoon conditions. An assessment of worst case condition and the influence of adjacent piers was made. Bed shear stress was determined in the the vicinity of the piers to determine the proper countermeasure design.
An OpenFOAM CFD model for the ebb tide condition was run using the boundary conditions determined by the 2-dimensional mode to assess if the proposed scour mitigation at the Second Vivekananda Bridge might adversely impact the adjacent railroad bridge.
Early in the schedule for dumping sand filled geotextile containers, a scanning sonar was used to approximate the location of the material to see how far the containers would drift.
Midway through the placement of crates filled with geotextile bags of sand, H2FLO Consuting ran a multibeam survey of the work to validate the llevel and overall placement of the material.
