Item Who is experiencing weathering? A question of belonging in the engineering profession(Canadian Engineering Education Association, 20-03-04) Radebe, Dimpho; Rottmann, Cindy; Chan, Andrea; Moore, Emily; Macdonald-Roach, EmilyDespite persistent efforts to diversify the engineering profession, inequities persist. As part of a larger research project on career paths, the authors conducted a large-scale survey of Canadian engineers with a minimum of 10 years’ experience in professional practice. This line of analysis explores Canadian engineers’ personal sense of belonging in the engineering profession. Results indicate that while 58.1% of survey respondents had a high sense of belonging, racialized women and white women disproportionately rated a lower sense of belonging, despite increases in representation. Further investigation reveals that for racialized women continued low visibility, discrimination, barriers to licensing, and views on what counts as engineering work were some of the reasons for a lower sense of belonging. This mixed-methods research reveals the hidden curriculum – institutional mechanisms – within the profession that contributes to weathering in the profession and highlights the importance of using an intersectional lens when looking at belonging.Item Determination of Generator Inertia(1961-01-24) Gordon, J.LThis paper deals with some of the considerations necessary in the selection of the rotating inertia required to be built into a hydro-electric generating unit, so that the unit will perform satisfactorily under the operating conditions for which it was designed.Item Speed Regulation for Hydraulic Turbines(1961-10) Gordon, J.L; Smith, W.JIn the annals of technical publications available to the engineering profession, there are many and varied papers dealing with specific aspects of speed regulation, selection of inertia constants for machines, power surges and the like. The authors have felt the need of a concise summary of the approach to the phase of hydroelectric station design. It is recognized, and indeed emphasized, that the use of unfamiliar formulae and graphs may be dangerous, if not used or supervised by those experienced in such design. However, it is essential that there be a standard approach in order to instruct engineers, facilitate checking and provide an orderly method of recording design tests and experience. The authors make no pretense at having developed new theories; rather have they condensed known methods of calculations in a form which can readily be used without length and laborious calculations.Item The Harca Hydro Development(Canadian Electrical Association, Hydraulic Power Section, 1970) Gordon, J.L.Item Experience with Cracking at Duncan Dam(1970) Gordon, J.L; Duguid, D.RConstruction of the Duncan Dam in British Columbia commenced in 1964, and was completed in April 1967, about one year ahead of schedule. During construction, several large transverse cracks formed through the dam due to differential settlement. This paper describes the formation of the cracks, their cause, the methods used to deal with the problem, and the changes in design required to preserve the integrity of the dam.Item Vortices at intakes(1970-04) Gordon, J.L.This article describes the development of design criteria to avoid vortices at low-head intakes, based on a study of 29 existing hydroelectric intakes.Item Duncan dam instrumentation(1971-01) Gordon, J.LSettlement at the 120ft-high Duncan dam reached 14ft during construction. This paper describes the instrumentation of the dam, and the development of a new type of settlement gauge which was installed to depths of 250ft in the soft sand-silt foundationItem The Foundation Cut-off for the Bighorn Dam(1971-03) Forbes, D.J.; Gordon, J.L; Rutledge, S.E.A 300 ft. high earthfill dam is currently under construction at Bighorn on the North Saskatchewan River in Alberta. The dam is founded on about 200 ft. of sands and gravels which are being sealed by a 2 ft. thick concrete cut-off wall. Construction of the wall commenced in December 1970, and is expected to be completed by May 1971. Construction is being undertaken from within a large heated enclosure where the temperature is maintained above 50° F. Bentonite slurry is used to maintain an open 2 ft. wide vertical sided trench which is then backfilled with concrete to form the cut-off wall.Item High Strength Steel Applications in Hydropower, Penstock Steel Specifications and Quality Control(1971-05-05) Gordon, J. L.Only 20 years ago most structural and plate steels in common use on hydro power projects had a yield point in the region of 28 ksi to 36 ksi. Now we have a multiplicity of steels with yield points ranging from 30 ksi to over 100 ksi, with the design engineer having to face the problem of which steel should be used in a particular application. Furthermore, since there are often advantages in using a high strength steel, the designer is faced with having to care fully consider the design conditions and steel properties other than the yield point, since the yield point is not the only measure of strength. In this paper I will outline some of the practical considerations which must be taken into account, confining the subject to use of intermediate and high strength steels in penstocks and turbine spiral casings, since this is by far the major area where such steels are used on power projects.Item The Maskeliya Oya Hydro Project(Montreal Engineering Company, 1972) Gordon, J.L.; Holroyd, A.W.; Matthews, W.G.The 100 MW Maskeliya Oya hydro project stage II is currently being built on the island of Ceylon. This paper briefly describes design and construction progress at a stage about half way through completion of the project. Detailed design and construction supervision is being undertaken by Ceylonese engineers under the direct supervision of four engineers provided by the consultant.Item The Bighorn Power Project(1972-10) Gordon, J.L.; Rutledge, S.E.Item Concrete Diaphragm Wall, Bighorn Dam(1973) Forbes, D.J; Gordon, J.L; Rutledge, S.EIn 1969 an agreement was made between the Government of the Province of Alberta, Canada and Calgary Power Ltd., a private utility company to develop the Bighorn site on a joint basis. It will provide a reservoir, backed up by an earthfill dam, of 1,165,000 (1,435 x 108m) acre feet, generate 108.000 kW of power and augment the low winter flows in the North Saskathewan river by release of the stored summer flood waters. The location of the site and general layout of the dam and power plant facilities are shown on Figure 1.Item Enlargement of St. Marguerite Spillway(1973-05-07) Gordon, J.L; Brittain, K.GThe St. Marguerite hydro development was completed in 1954 and supplies power to the Seven Islands area. It comprises a concrete gravity dam with four spillway gates and adjacent powerhouse. In May 1966, a heavy storm precipitated 1.5 inches of rain onto wet snow causing a flood which peaked at about 60,000 cfs, some 50% in excess of the normal spillway capacity. Subsequent investigations of maximum floods in the region indicated the possibility of flood peaks ranging from 100,000 cfs to 150,000 cfs. Several alternative designs were compared to add spillway capacity, from which it was decided to cut seven openings into the dam, to be closed off by stoplogs, with the stoplogs released by a small hydraulic jack operated by a portable hand pump. By using 4.5 ft. of flood surcharge on the reservoir, the total spillway capacity was increased to 80,000 cfs, whilst a flood of 100,000 cfs can be discharged with a water level 1 ft. below the dam crest. All modifications were built into the dam without interrupting operation, and without disturbing traffic on the public road across the dam.Item Turbine Selection for the Kainji Extension(1974-03) Gordon, J.LThis paper outlines the studies undertaken to determine the maximum size of unit which could be intalled.Item Calculation of transients in a system of algebraically connected dynamic components using a new numerical algorithm(Institute of Electrical and Electronics Engineers, 1975) Semlyen, AdamItem The Bayano Hydro Project(Canadian Electrical Association, 1975-03) Gordon, J.L.; Karnick, P.D; Walker, W.S.; Winniki, L.B.The 150 MW Bayano Hydro Project is currently under construction 90 km east of Panama City, Panama. It comprises the largest construction project in Panama. When completed it will contribute 550 GWH of energy annually to the system, in a country where the demand for power is expected to double in the next five years to 1980. This paper describes the project, the equipment being installed, and some of the problems encountered.Item Exporting Technology: Working "On the Spot" Overseas(Montreal Engineering Company, 1977-10) Gordon, J.L.Item Installing hydro units in restricted spaces(1977-12) Gordon, J.L.Many North American utilities are currently adding capacity to existing hydro developments, and often the new units are larger than the original ones. The way in which civil and hydraulic constraints at three sites affected the size of new units added is described.Item A re-assessment of small hydro development in Nova Scotia(1978-02) Gordon, J.L.; Penman, A.C.; Hutt, R.Most of the major rivers in Nova Scotia have now been developed for hydro power. However a large number of small sites still remain undeveloped mainly due to the high cost associated with building small hydro plants designed to the same criteria as used for large scale hydro projects. A re-assessment of the design criteria is required in order to reduce the cost of small hydro. This paper includes a review of such design criteria a description of methods to quickly evaluate power potential and concludes with a brief description of a 0.5 MW hydro plant in Ontario.Item Determination of Hydro Generator Rotor Weight and Its Effect on Powerhouse Crane Capacity(1978-03) Gordon, J.L; Thicke, R.HThe generator rotor weight, MVA output and speed, at over 120 hydro installations throughout the world have been examined along with the powerhouse crane capacity. Empirical formulae have been developed to calculate rotor weight based on known MVA output and speed. In addition, special cases such as large slow speed generators, effect of added inertia, and partial assembly of generators have been investigated to determine their effect on powerhouse crane capacity.
