Water Resource Associates

HYSIM-AQUATOR was developed jointly by Water Resource Associates and Oxford Scientific Software Ltd during a three-year research and development contract for SNIFFER in 1999-2001. The results of the research were published by the Foundation for Water Research in February 2001.

The original integrated HYSIM-Aquator software package was destined for use in determining the deployable output of water supply systems in Scotland and Northern Ireland. Since then, HYSIM-Aquator has become the preferred choice for water resources system modelling and is used routinely by water companies, government agencies and consultants working in the field of water resources planning and river basin management. The largest river basins in the United Kingdom are modelled using Aquator.

Aquator is a powerful application for developing and running conjunctive use water resource system models. It is equally at home with simple models having just a few components as well as large complex models comprising many hundreds of components.

HYSIM is a hydrological simulation model (rainfall-runoff model) which uses rainfall and potential evaporation data to simulate the hydrological cycle (surface runoff, percolation to groundwater and river flow) on a continuous basis.

HYSIM’s parameters define in a realistic way the hydrology and hydraulics of the whole river basin (watershed).

WRA provide a model, termed HYSIM-CC, to quantify the effects of climate change. With the model you can: i) Work with IPCC SRES climate scenarios, ii) Import climate and other data, iii) Analyse changes to river flow, runoff, soil moisture, groundwater recharge, snow melt, frost days and irrigation demand, iv) Simulate the impacts anywhere in the world, and v) Output the results in a range of graphic formats or as csv files.

INCA is a dynamic, processed-based model providing representation of flow and water quality with plant and soil system dynamics and in-stream biogeochemical and hydrological dynamics. The INCA model has been used successfully to assess a wide range of environmental change issues in catchments.

Professor Futter is a water quality modeller with extensive experience in model development and application. He is a key member of the INCA development team and has led or contributed to the development of models for nutrient, mercury and organic pollutant fate and transport. Most recently, he has been part of the development team for INCA-Tox, a generic, catchment-scale model for simulating the fate and transport of legacy and emerging organic pollutants. He is skilled in software development and environmental information management and has developed several tools for model calibration and sensitivity analysis. Martyn is an expert on European water policy including the Water Framework (WFD) and Floods Directives (FD). He has specialist regional expertise in Fennoscandia, the Baltic States, the UK and Canada and sectoral expertise in forestry, drinking water supply, acidification and diffuse pollution.

Dr. Robin Hall has 27 years experience as a hydrologist and was formerly employed for 23 years at the Centre for Ecology and Hydrology (CEH), Wallingford, (formerly Institute of Hydrology). He has extensive experience in experimental design, measurement and modelling, in both research projects and applied work, covering a wide range of hydrological topics including: evaporation (from vegetation, soil and water bodies); soil water; groundwater; stream flow and surface water runoff, and catchment water balances.

Dr. Mandeville specialises in strengthening the operation of hydrological services for overseas governments, from basic data collection through hydrometeorological analysis to management of the water resource. Has also undertaken a substantial number of regional hydrological studies.
