The main progress has been in the discovery of oceanographic phenomena new to science and an increased understanding of the behaviour of sediments. These advances have been based on field experiments using new instruments and techniques developed by myself in conjunction with others. These new concepts have been successfully applied to various engineering problems.

In the port engineering field, Dr Kirby, accompanied by a small number of very expert colleagues, has developed and brought to commercial fruition two new Sediment Management Systems. He is the co-inventor of the Nautical Depth concept, as well as the continuous vertical gamma-transmissance, and later, towed undulating (Navitracker) profilers with which to measure this. Nautical depth is a concept applicable to fairway maintenance in high turbidity (fluid mud) systems. This initial concept must now be termed Passive Nautical Depth. It has been evaluated, ratified and promulgated world-wide by PIANC. Where applicable, for example, at Rotterdam/Europort (Holland), Zeebrugge (Belgium) and elsewhere it has resulted in major cost saving. In a new iteration, Dr Kirby has provided part of the science underpinning Active Nautical Depth, a method to further minimise maintenance dredging need and at the same time use the fluid mud cloud to decontaminate the sediment in situ. The prototype port for this is Emden in Germany. Dr Kirby is also the co-developer of a revolutionary patented technique for reducing eddy-induced siltation in the entrance to blind-ending basins in lower turbidity regimes. These Entrance Flow Optimisation Systems (EFOS) involve Sills and Current Deflecting Walls and, from European Union-funded generic research contracts and practical experience in tidal situations, have been found to reduce sediment input from all three of the principal mechanisms. Creation of a design protocol for these systems has also required development of dedicated design technologies, which themselves have a wider application outside the immediate port engineering field. There is now years of practical experience with these systems at the prototype test site, Hamburg in Germany. Their use is now spreading in the port industry, with further systems envisaged for Hamburg as well as for Antwerp and potentially Rotterdam/Europort, three of the top ten ports in the world. They also contribute in a major way to an important change in modern port design, namely replacing impounded with tidal basins at high tidal range and turbid ports, a trend arising from competitive pressure from the container shipping trade. Benefits from these systems span a broad spectrum of economic and environmental issues and involve extremely large sums of money.

Dr Kirby is a shareholder and director in Balticon International, a company using new types of highly mobile recycling plants to decontaminate waste terrestrial and marine mineral material. Following separation, a range of disposal options can be applied to the concentrated contaminants, whilst the primary minerals produced find a wide range of beneficial uses, for example in habitat creation or in manufactured products. This latter activity complements the two Sediment Management Systems.

In the coastal engineering field, Dr Kirby is the inventor of a patented self-sustaining soft sediment coast protection methodology, Tidal Flat Regeneration, which involves placing wave attenuators and muddy dredge material to alter whole mudshore cross-sectional profiles from low and concave, to high and convex shapes. Similarly he is the co-developer of a “top down model” or mudcoast management system, S-factor Analysis, which permits shore stability and erosion-potential to be quantified for the first time. Dr Kirby has proposed the Mehby Rule as a conceptual model for mudshores to stand alongside the accepted Bruun Rule for sandy shores. This encompasses and explains in summary form the contrasted behaviour of muddy and sandy foreshores.

Dr Kirby was Chairman of the PIANC MarCom Working Group 43 “Minimising Harbour Siltation” (MHS) which sought to evaluate and promote generic Sediment Management Systems around the world. The report was published in October 2008.

He is a founding member of the SICEM, the Sediment Innovation Centre in Emden, Germany, which aims to implement generic MHS technologies around the world with commercial links to Germany Belgium, France, Italy, Brazil, China and the USA.

Dr Kirby has written more than 60 reports and papers on the Severn Estuary (UK) and 15 papers on the Medway Estuary (UK), two eroding muddy coastal systems. He has been involved in every phase of Severn Tidal Power Barrage study of the modern era and supplied his scientific archive to facilitate progress with ongoing investigations.

1965-1968       London University Ph,D. student ‑ Cohesive sediment transport in Medway Estuary, Kent.

1968-1970       Continental Shelf Unit, Institute of Geological Sciences, Edinburgh – marine geologist and chiefly responsible for unconsolidated sediments. Field work involved marine geophysical surveys using CSP equipment (pinger, boomer, sparker, magnetometer, gravimeter) and geological sampling surveys (of rock and unconsolidated sediment).

Early equipment was primitive and Dr Kirby was responsible for the design of a new gravity corer and the first British vibrocorer (manufactured under licence by Aimers McLean Ltd). He introduced the first small remote control rock drilling equipment and was responsible for establishment of the I.G.S. sedimentology laboratory.

1970‑1984       Senior, later Principal, Scientific Officer, Institute of Oceanographic Sciences, Taunton. Leader of joint Anglo‑Dutch investigations of mobility of large sand waves in VLCC routes in Southern North Sea. Vibrocorer development continued and techniques devised for non‑destructive quality control of undisturbed core samples.

Established “Cohesive Sediment Mobility Project” aimed at understanding the fundamental physics governing the behaviour (erosion, transport, deposition and consolidation) of cohesive sediment based on field experiment. Responsible for leading sedimentological investigations as part of Cohesives Project in Severn Estuary and Bristol Channel (UK) and in Europort (Netherlands). Responsible for design of experiments and data processing. The main scientific achievement has been the recognition of vertical and horizontal discontinuities in the suspended solids field. Dr Kirby proposed the term LUTOCLINE to describe the vertical discontinuities. Lateral discontinuities are Suspended Sediment Fronts.

Further to identification of the lutocline phenomenon, together with a co-author he devised the first comprehensive mathematical quantification of the mechanisms of formation, stabilisation and dissipation of lutoclines. Lutocline physics is now a major topic of enquiry at many research institutes worldwide.

Requirements of high calibre experiments at sea led to the design of special items of  equipment.  These include:‑

‑  Backscatter Density Probe [Built at AERE Harwell]

–  Transmission Density Probe [Built under licence at AERE Harwell]

–  Vertical Profiling Array [for silt, temperature and salinity]

This fundamental research has led to the introduction of new technology and advice to the dredging and port industry as follows:‑

1974 – 1984       Adviser to Netherlands Government, Associated British Ports at Hull, Immingham and Port Talbot, to BP and Forth Ports Authority at Grangemouth and to Port of London Authority at Tilbury on mud surveying and dredging problems, especially the use of in situ density measuring devices to monitor the channels as an alternative to conventional echo sounder surveys. The concept of a “Nautical Depth” was devised (density 1.2) being the density horizon within mud layers above which VLCC’s can safely sail.

The equipment and technique have been adopted worldwide.

1982                  Expert witness advice in court case concerning dispute over effects of capital dredging scheme on surrounding oyster beds in Loch Ryan, Scotland.

Other experience has been gained as follows:‑
