My doctoral research (1995-1999) considered design-management interactions on large-scale canal irrigation systems, with a focus on Southern Africa.
This work attempted to characterise and model the factors that influence the performance of irrigation schemes with a view to providing guidance on system evaluation and best practices for rehabilitation and modernisation. The origin of this work can be traced to my work as a CDC Technical Officer on the Inyoni Yami Swaziland Irrigation Scheme from 1985 to 1989. I returned to the Swaziland lowveld in the nineties to undertake the field research for the PhD.
The paper that describes how surface irrigation systems can be attuned to make them more manageable is Lankford, B. A. (1992) The use of measured water flows in furrow irrigation management - a case study in Swaziland. Irrigation and Drainage Systems 6: 113-128
Lankford, B. A. and Gowing, J. (1996) The impact of design approximations on the operational performance of an irrigation scheme: a case study in Malaysia. Irrigation and Drainage Systems 10: 193-205 (Kluwer Academic Publishers)
The two chapters I wrote while studying for the PhD are:
Lankford, B.A. and Gowing, J. (1996) Understanding water supply control in canal irrigation systems in Water Policy: Allocation and Management in Practice by P. Howsan and R. Carter (eds.) E & FN Spon, London, pp 186-193
Lankford, B. A. and Gowing, J. (1997) Providing a water delivery service through design management interactions and system management in Water: Economics, Management and Demand Kay, M., Franks, T. and Smith, L. (eds) E & FN Spon, London, pp 238-246
I also apply the ideas of manageability of infrastructure to the river basin level, asking whether irrigation headworks enable and foster a more equitable and transparent apportionment of river flow water over a wide range of discharges. The three papers relevant here are:
