The experience of our Directors covers hydrometric network design, instrumentation, data capture and processing, flood estimation and forecasting, low flow and drought studies, hydropower operation, modelling of complex conjunctive use water resource system, arid zone hydrology and wetland hydrology. WRA has extensive experience in water quality studies and modelling. A number of staff are experienced project managers.

We also specialise in producing high quality software for the water industry either as bespoke applications or as products for general use. Software products include a catchment model, conjunctive use water resource simulation models, a river water quality model, chart digitising software and liming control software for acid rivers and lakes.

We give below links to summary CVs of WRA Directors. For more information on any Directors of our company please contact us.
