We have over twenty years experience providing hydrology consulting services. Flood risk assessment, while the most common topic encountered within hydrology, is just one part of the picture. It is through a detailed understanding of an environments’ hydrology that risk to property may be evaluated. At Millard we have the experience and skills to build hydrological models that inform flood risk assessments, and infrastructure and drainage design solutions to ameliorate risk, using a variety of well established modelling techniques and software tools, which have found national and global accreditation for their suitability to river and coastal modelling.
Depending on the requirements of any specific project we have the capability of creating one or two dimensional hydraulic models; or a combination of both. One dimensional hydrodynamic modelling is an established technique for the analysis of river systems. Flood extents and depths can be investigated, for various flow conditions and time steps within a flood event. Flood flow paths are represented by modelling rivers as uniform channels and a branched or looped network of these channels can represent a floodplain and river system. Hydraulic structures can be included in the analysis. Although the analysis is sufficiently detailed for some projects; because natural floodplains are not uniform in shape, vegetation cover or elevation, one dimensional models have limited accuracy.
Two dimensional flood modelling allows a more detailed representation of floodplains on a finer scale and can accurately establish flow patterns in coastal waters, estuaries, rivers, floodplains and within inundated urban areas. It is much closer to reality and eliminates uncertainties. It also permits the accurate analysis of flood defence breach scenarios in coastal, tidal or fluvial locations. Modelling software includes TUFLOW, Infoworks RS / ISIS, HEC-RAS and Micro-Drainage.
