Paper format. National Examinations, May 2019, 16-Civ-B4 Engineering Hydrology, three hours’ duration, closed book with one candidate-prepared two-sided aid sheet (8½″ × 11″) and one approved Casio or Sharp calculator whose model designation must be written in the work book. Seven problems are printed, each divided into sub-parts (i), (ii) and (iii). Page-1 Note 4 states that any five (5) questions constitute a complete paper and that only the first five answers appearing in the work book will be marked; Note 5 weights every problem at twenty (20) points, for a maximum of one hundred (100) points. All seven problems are solved here, because this document is a study resource rather than a timed sitting. The sub-part mark values quoted below are the printed marginal marks, which on this sitting agree exactly with the page-6 marking scheme (7/7/6, 7/7/6, 7/7/6, 8/6/6, 6/7/7, 6/6/8, 10/5/5).

Check — every number below is the solver’s own illustrative value. All seven problems on this sitting are discussion questions; the paper supplies no numerical data whatever. Where a short calculation appears below it is there to demonstrate the method being asked about, and its inputs are declared explicitly in a Given line as assumed, representative Canadian values. They are not exam data. A candidate who assumed different but reasonable values and carried them through consistently would earn the same marks, and the examiner’s marks here are awarded for the explanation, the governing equation and the stated assumptions.
