“…Simulations were on a uniform 300 m × 300 m horizontal grid with 73 vertically varying Z-levels, to a maximum depth of 70 m. The top three layers were each of 0.1 m depth and the next 40 layers were (through the epilimnion and metalimnion) at 0.5 m. The hypolimnion had 30 layers with depths varying from 1.0 m to 5.0 m. Simulations on a 200 m × 200 m horizontal grid confirmed the results to be grid independent at the basin-scale (Paturi et al, 2012). The model grid covered the region from the Sandhurst Shores intake in the southwest to the Brockville intake in the northeast (Fig.…”

“…During the same period, vertical profiles of currents were recorded using an upward looking RDI Workhorse acoustic Doppler current profiler (ADCP) with 1 m vertical bins (sampled every 30 min at 1200 kHz) at Stations 1263 (106 days) and 1264 (111 days). For a detailed description of the data, please see Paturi et al (2012; …”

“…The IPZ-1 is a set-area of 1 km radius around each intake. The IPZ-2 is a zone defined around each intake that encompasses a 2-hour travel time (i.e., emergency intake shutdown time) of influent water during a 10-year return period wind event (see Paturi et al, 2012). The IPZ-3 is defined as the area where the water could reasonably travel from a release point to the intake during a potential contaminant spill or discharge over seasonal timescales.…”

“…This is a region in which there have been recent investigations using numerical models such as Delft3D [6,9], ELCOM [10] and FVCOM [11]. The purpose of this study is to investigate how effectively SWAN can simulate surface waves over a large scale from an open lake, around islands and over channels and shoals, to a SCH protected by a breakwater.…”

A surface wave model using three nested grids is applied to the eastern end of Lake Ontario to investigate wave propagation from an open lake environment to a small craft harbour protected by a breakwater. The Simulating WAves Nearshore (SWAN) spectral wave model, coupled with the Delft3D hydrodynamic model, is applied to simulate a series of storms in November, 2013. The model results are compared to observations from two pressure sensors, and used to quantify wave properties around existing and future breakwaters to evaluate the bulk changes to the harbour configuration. Overall, the results indicate that the rubblemound breakwater reduces wave heights in the existing harbour by 63% compared to no breakwater, and that the addition of a surface breakwater extension could reduce wave heights by an additional 54%. Wave height attenuation was found to be highly dependent on the incident wave direction relative to breakwater orientation. The spectral wave model is useful for simulating wave transformation for broad directional spectra in wind-sea conditions over large scales to semi-protected areas such as small craft harbours.

“…The complexity of the bathymetry in the Kingston Basin region and the smaller spatial scales of the physical processes within it and the lake are extremely well suited to a finite volume numerical model that uses an unstructured mesh rather than uniform grid models used in the past (Huang, Rao, Lu, & Zhao, 2010;Paturi, Boegman, & Rao, 2011). In this study, the Finite Volume Coastal Ocean Model (FVCOM) was used.…”

Using an unstructured grid finite volume model (Finite Volume Coastal Ocean Model (FVCOM)), numerical model simulations were generated and compared for the 2006 summer hydrography of the Lake Ontario-Kingston Basin system. Simulations are forced with surface forcing from two different sources: observations collected by Environment Canada and output generated by the North American Regional Reanalysis (NARR). Simulated temperatures are compared with observations collected during the same time period to assess the viability of the NARR dataset as a source of long-term surface forcing fluxes. Root mean square errors for vertical temperature profiles, comparisons to lake surface temperatures, and Kingston Basin current observations, indicate that using NARR data to force an FVCOM model simulates the hydrography as well as simulations forced with in situ observations. RÉSUMÉ [Traduit par la rédaction] À l'aide d'un modèle aux volumes finis à grille non structurée (Finite Volume Coastal Ocean Model (FVCOM)), nous avons généré et comparé des simulations par modèle numérique pour l'hydrographie de l'été 2006 du système lac Ontario -bassin Kingston. Les simulations sont forcées par un forçage en surface provenant de deux sources différentes : les observations recueillies par Environnement Canada et la sortie produite par le NARR (North American Regional Reanalysis). Nous comparons les températures simulées avec les observations recueillies durant la même période pour évaluer la viabilité de l'ensemble de données NARR en tant que source de flux de forçage en surface à long terme. Les erreurs-types pour les profils verticaux de température, les comparaisons avec les températures de surface du lac et les observations du courant dans le bassin Kingston indiquent que l'utilisation des données NARR pour forcer un modèle FVCOM simule l'hydrographie aussi bien que les simulation forcées par des observations in situ.
