Hamish Weatherly

Principal Hydrologist


Hamish Weatherly M.Sc, P.Geo, LG, has 25 years of international consulting experience. His main areas of expertise are hydrology, fluvial geomorphology, and river engineering, which he applies to the mining, pipeline, and government industries. He has worked extensively on the development of water management plans for proposed, in construction and existing mines, as well as closure activities. This work includes diverse climatic environments such as Alaska, Canada, Chile, Argentina, Russia, and the Dominican Republic. Hamish has been involved in all aspects of water management including the development of site water balance models, water management strategies, and the design of infrastructure such as pond volumes, pumping capacities, diversion channels and spillways. Hamish has also completed extensive work on channel stability problems, with a particular emphasis on anthropogenic and natural influences on channel planform and sediment transport rates. This knowledge is routinely applied to the protection of linear infrastructure (e.g., pipelines, roads, and railways) at watercourse crossings and encroachments. Mr. Weatherly’s geomorphology expertise is complemented by his knowledge of river engineering including: hydraulic assessment of bridge, pipeline and culvert crossings; hydraulic modeling of flooding hazards; and the integration of river morphology and flow hydraulics in assessing bank erosion and scour.
