Expertise

This is the website of J. Malcolm Ashworth a freelance Hydrogeologist and Water Resources Specialist with +40 years of experience in ground and surface water data analysis, mapping, modelling, assessment and integrated water resources management. I offer independent and international expertise in quantifying and solving water resource and groundwater issues.

Guiding principals:

1. Strive for excellence.
2. Put the client’s interests first.
3. Tell the truth even if this challenges the client’s opinion.
4. Only perform work that I can do well.
5. Only advise work that is necessary to achieve mission results.


Countries of Work Experience

My work experience encompasses 18 countries across Africa, Asia, Europe and North America with different international organizations including the World Bank, ADB, USAID, AFD, FAO, and many private firms such as GEO-Resources, Lahmeyer, BCEOM, Water Resources Consultants, Komex, Mott MacDonald and Uhl & Associates.

This has included participation on numerous feasibility studies and master plans for developing new water sources for urban and rural communities and irrigation. I have provided project design, construction management and oversight for hundreds of boreholes worldwide. I bring extensive experience in surface geophysical surveys, deep well design, the testing and development of production wellfields, and specialist knowledge of Scavenger and Artesian Well construction. 

Expert services are available for creating groundwater models for solving and predicting groundwater flow and transport problems. Similarly, surface water models for predicting the likelihood of different flood events and their impact are also provided. This includes flood risk assessments using the BREEAM methodology for master-planning projects, infrastructure and buildings. Assistance with Environmental Assessments, compliance with Remedial Targets and the effects of Climate Change are also offered.

Other skill sets include competence in using industry-standard software packages such as ArcGIS, Manifold, Global Mapper, Modflow, Aquifer Test, Surfer, Aqua Chem, HEC-RAS and HEC-HMS. I am also an expert at obtaining missing and representative resources from stakeholders, the internet, field inventories and pilot projects, collating and processing satellite and water resources information into databases and then utilising these data to create maps and models for assessment and management purposes.
