Projects:

HS2 – Greatmoor No.4 Watercourse Diversion (Completed: January 2023)

I led design of the watercourse diversion. This saw me design: 

  • Sinuosity to a heavily modified straightened channel 
  • A channel appropriate for the size of catchment. 
  • Step pool and cascade features. 
  • Natural gravels in the channel bed to create Riffle features. 
  • A stable and vegetated channel encouraging habitat establishment.

HS2 – River Ray Watercourse Diversion (Completed: October 2022)

I led design of the watercourse diversion. This saw me design: 

  • A channel appropriate for the size of catchment. 
  • Enhancement through the incorporation of berms. 
  • Natural gravels in the channel bed and within the base of the culvert to create Riffle features. 
  • A stable and vegetated channel encouraging habitat establishment.

Loch Katrine Landslip Emergency Works Scotland (Completed: September 2021)

An emergency works project to reopen the road damaged by landslips. I was the lead designer & produced the designs for the construction of temporary & permanent repairs of watercourse crossings & realignments to reopen the access road around Loch Katrine (Glasgow’s water source).
I am a Chartered Civil Engineer who specialises in watercourse/drainage design. My career has spanned many disciplines such as dams and reservoirs, surface water drainage to culverts and watercourse diversions. I have designed watercourse diversions on jobs such as the A9, A82, HS2 & Loch Katrine Landslip. I have undertaken all RRC hydromorphology training courses and am currently applying these principles in my day-to-day job as demonstrated by my project examples.
