Experience
Robert (“Bob”) Bower is an internationally recognised practitioner known for applying systems-thinking approaches to complex water challenges, particularly those emerging under a changing climate. Over more than 25 years, his work has been grounded in Integrated Water Management (IWM), with a strong focus on groundwater replenishment and aquifer restoration.
Bob has led the development and delivery of groundwater programmes ranging from nature-based solutions to engineered systems—taking projects from concept, through construction, to long-term operation. Many of these programmes have demonstrated sustained success over multiple decades in stabilizing groundwater levels and restoring associated ecosystems.
In addition to groundwater, Bob brings deep experience in riverine hydrology and water-quality science. Throughout his career, he has led multi-stakeholder initiatives that bring together irrigators, regulators, municipalities, and Indigenous treaty partners to deliver practical, durable solutions in degraded and water-stressed catchments in both western countries as well as SE Asia.
Bob’s contributions have been recognised internationally. His awards include the International Association of Hydrogeologists (IAH) Lifetime Contribution Award (2022) and the National Walter C. Loudermilk Award (2006), co-awarded by the National Watershed Management Council in recognition of work restoring one of the United States’ most endangered rivers.

Our Name
Our name is inspired by the process by which rivers renew groundwater through alluvial soils - a reminder of the vital connection between water, land, and life.
H2Alluvium = Water + Soil
H2O (Water)
Water from streams or rain percolates through soil, eventually reaching and contributing to the vast underground reservoir of water known as aquifers.
Alluvium refers to the sediments of all types that are moved, rounded and then deposited by running water found in river and stream floodplains. Through this alluvium material water is naturally filtered on its journey to join the aquifers below. As rivers move toward the sea, this same water emerges from the ground through the alluvium materials into the rivers and ultimately the sea.
”The grand circle of movement of water from ocean to atmosphere to continent and back to the ocean is the essential mechanism that allows organisms - including humans - to emerge, to develop, and to live on Earth”.
