“…Hill et al (1997) and English et al (1997) found that changes to the annual flow regime associated with regulation had impacted the SRD. Lacustrine deltas are often fluvially dominated because of relatively low wave erosion and tidal activity associated with lakes, which results in rapid deposition of suspended material and an arcuate morphology (Axelsson, 1967;Dahlskog et al, 1972, Andren, 1994.…”

Abstract:A limited amount of research has focused on northern lacustrine deltas and the impacts of basin processes prevalent at these deltas. Wind-forced seiche events have received little focus in deltaic studies. The Slave River Delta, located on the south shore of Great Slave Lake (GSL), NWT, is an ideal environment to study the prevalence of wind-forced seiche events and the impact of seiche events on the hydrodynamics of the delta. This paper presents an historical analysis of seiche activity on GSL and the effect of seiches on water levels of the Slave River Delta. The seasonality, frequency, and magnitude of seiche events on the lake are quantified. A description of the wind characteristics that force these events is included. The radial distributary pattern of the delta suggests that water level response to seiche events within the delta may be particularly complex. Hydrologic data from delta distributaries illustrate the temporal and spatial dynamics of seiche response. During the open-water season, seiche response in the delta is affected by the seasonal hydrograph of the Slave River and wind conditions. Spatially, the slope of delta distributaries governs seiche response. Responses are most similar among zones in the delta rather than among different distributaries.

“…The dissolved load was determined using APHA (1976) methods involving titration of samples in an on-site laboratory shortly after collection. The individual density differences resulting from suspended concentrations and dissolved concentrations were calculated following Axelsson (1967). No sample contained more than 5 percent by weight of material over 0.0625 mm in size.…”

“…A detailed discussion of the budget is given in Weirich (1985). The individual density differences resulting from suspended concentrations and dissolved concentrations were calculated following Axelsson (1967). The density difference resulting from thermal differences was calculated from Killworth and Carmack (1979).…”

This paper outlines the findings of a study of sedimentation processes in a shallow glacial lake in which an integrated, basinwide instrumentation network, a multidimensional underwater sensor array, and a central rapid scan data-recording system were employed to obtain detailed information on processes both in and around the lake. The results presented here focus upon the nature and occurrence of density currents in the lake over a two-season period. The general character of the system includes a largely isothermal lake environment, water residency times of only 8-12 days, and considerable sediment throughput with over 30 percent of the incoming sediment load moving through the system. The lack of significant thermal stratification and the tendency toward generally isopycnal conditions precludes a conventional over-. inter-, and underflow model of density currents. It appears instead that an over-and underflow model with homopycnal mixing is more appropriate. The overflows, largely wind driven, are frequent events, and on occasion wind-driven translake overflows occur. Underflows, occurring with density differences as low as 0.19 kg 1 r 3 , are also frequent and may reach velocities capable of eroding the finer materials. Core data support many of the findings from the instrumentation network. Finally, the results point to the need for careful measurement of both input and output variables and the significance of even small variations in the entrance conditions on sedimentation processes in the lake.
