Elevated stream tempera-ture is a key water quality stressor for causing degraded aquatic biota. Dis-charges from urban drainage and aggregate extraction activities contribute to aquatic biota degradation, since runoff and detention pond releases elevate in-stream temperatures. This chapter describes a simple continuous in-stream temperature model that has been integrated with the existing GA WSER (Guelph All-Weather Sequential-Events RunoffV6.4) model to evaluate the impacts of elevated stream temperatures on aquatic biota in developing subwatersheds. The chapter gives a brief overview ofthe hydrologic computations available in GA WSER. The corresponding in-stream temperature (energy exchange) processes for the major hydrologic sources (and sinks) within a watershed (e.g. rain and snowmelt runoff, subsurface and groundwater baseflow, evapotra-nspiration, channel routing elements, reservoirs, and recharge ponds) are out-lined in de...

Elevated stream temperature is a key water quality stressor for causing degraded aquatic biota. Discharges from urban drainage and aggregate extraction activities contribute to aquatic biota degradation, since runoff and detention pond releases elevate in-stream temperatures. This chapter describes a simple continuous in-stream temperature model that has been integrated with the existing GA WSER (Guelph All-Weather Sequential-Events RunoffV6.4) model to evaluate the impacts of elevated stream temperatures on aquatic biota in developing subwatersheds. The chapter gives a brief overview ofthe hydrologic computations available in GA WSER. The corresponding in-stream temperature (energy exchange) processes for the major hydrologic sources (and sinks) within a watershed (e.g. rain and snowmelt runoff, subsurface and groundwater baseflow, evapotranspiration, channel routing elements, reservoirs, and recharge ponds) are outlined in detail. The model uses vegetative canopy information in computing the energy exchange process at the air-water interface. Early results of applying the model to the Blair and Bechtel Creeks subwatersheds are presented.

When they use ISO 14064 for quantification, reporting and verification, it will ensure that “a tonne of carbon is always a tonne of carbon.”
