Jason Hallowes
Director and Technical Specialist
Jason Hallowes has been a practicing hydrologist since 1998. He has participated in a broad range of projects with interdisciplinary teams. Work experience includes, IWRM, hydrological and hydraulic modelling, Flood modelling, River Basin Studies, Risk based hydrological assessments, Application development, GIS, Fortran and VB programming, Project management and Research.
A key interest and focus extending over his working career has been the application of real time systems and forecasting in water resources management. This began with his MSc thesis on the “Evaluation of a methodology to translate rainfall forecasts into runoff forecasts for South Africa”. He considers that the effective implementation of such systems can ameliorate risks associated with both flood and drought disasters, saving lives, preventing considerable hardship and reducing financial losses in many areas around the world.
As a Managing Director of EkoSource Insight his focus is primarily on business development, general and project management while he still participates in training and specific project activities when required.
Mehari Frezghi
IWRM DSS Specialist Lead
Mehari Frezghi is an Agricultural Engineer with more than 10 years of experience in the fields of in integrated water resource management, flood modelling and water resource information management. It involves practical modelling using different hydrological, hydraulic and water allocation models and programming experience in setting up decision support systems and information management systems. He has significant project management experience and wealth of experience with the relevant software applications related to hydrology, hydraulics, water resources system analysis and information systems. He has a good knowledge of different programming languages to assist in implementing decision support systems for water resource management.

Kevin Greaves
IWRM IMS Specialist Lead
Kevin Greaves has an MSc in Agricultural Engineering. Mr Greaves’ specific areas of specialisation are: - Hydrology and Water Resources Systems Modelling - Hydraulic and Hydrodynamic Modelling - Water Resources Decision Support Systems – Data and Business Analysis - Information Product Design - Spatial Analysis in GIS - Irrigation water use and modelling. A large focus of his work has been the establishment of online Decision Support Systems for water resources and water system management. These systems integrate hydrological data with modelling software to produce insight, or forecasts, into the response of water system to different user defined operational strategies. River basins where he has been involved in the setup of such systems include the Mhlathuze (KZN), Lower Orange (Northern Cape), Orange Fish Sundays (Eastern Cape), Western Cape Water Supply System and Crocodile (East) Rivers in South Africa.
Through different project consultancy assignments, Mr Greaves has also configured and analysed water resources systems in Malawi, Zambia, Zimbabwe, Mozambique and Malaysia. Many of these consultancy assignments included assessing the impact of climate change on water resources systems. This was completed through the use of different hydrological and water resources modelling software. During these projects it has been a requirement to interact with data and information from many different sources both real time and archived.
