“…First, storm flow induces hysteresis in the instantaneous interaction of stream discharge and DIN and SO 4 2 exports, which leads to large errors in estimates of annual DIN and SO 4 2 exports (Takeda, 2001). The hysteresis pattern is caused by the different concentrations between rising and receding limbs of a hydrograph for DIN (Ávila et al, 1992;Evans et al, 1999;Butturini and Sabater, 2002;Zhang et al, 2007) and SO 4 2 (Ávila et al, 1992;Rose, 2003). Second, storm flow sampling is time consuming, which increases the costs related to water sampling and chemical analysis.…”

Abstract:To investigate the effects of storm flow samplings on the evaluation of DIN and SO 4 2 budgets, we conducted storm flow samplings and discrete interval (weekly) samplings of stream water, throughfall, and stemflow. This investigation lasted for three years and took place in a small forested watershed in western Japan. Annual exports were calculated by the sum of the load (L total )-sum of the discharge (Q total ) relationships obtained by storm flow samplings. These were then compared to calculated ones that were based on LQ relationships obtained by discrete interval sampling. The results of discrete interval sampling showed that the relationships of DIN or SO 4 2 concentration to the discharge amount found in stream water differed from those of storm flow sampling. This was especially notable in years with higher annual precipitation and subsequent higher annual discharges. Also, exports of DIN and SO 4 2 during storm flow periods accounted for 83% and 78% of annual exports on 3-year averages, respectively. These results confirmed that storm flow samplings are essential for estimating annual exports of DIN and SO 4 2 . Annual exports that were calculated based on just discrete interval sampling (46% and 17%, respectively) overestimated DIN and SO 4 2 from discrete interval and storm flow samplings on a 3-year average. These overestimates were pronounced in years of higher discharge, and critically affected the rates of net-retention or export of DIN and SO 4 2 . The relationship of smaller input than output of DIN was reversed if storm flow sampling was included.

“…Water flow into and out of the hyporheic zone is influenced largely by advective exchange with the river, a process generally controlled by channel morphology, pressure head of overlying surface water, and the permeability of riverbed sediments (Landon et al 2001;Wörman et al 2002;Cardenas and Zlotnik 2003;Rose 2003). Consequently, the magnitude of river flow and the underlying geology can significantly affect chemical, physical, and biological gradients within the hyporheic zone, which ultimately will affect the structure and function of aquatic ecosystems (Stanford and Ward 1993;Curry et al 1994;Wroblicky et al 1998;Soulsby et al 2001;Alexander and Caissie 2003).…”

SummaryThe Pacific Northwest National Laboratory conducted this study for the Bonneville Power Administration (BPA) with funding provided through the Northwest Power and Conservation Council (a) and the BPA Fish and Wildlife Program. The study was conducted in the Hanford Reach of the Columbia River. The goal of study was to determine the physical habitat factors necessary to define the redd capacity of fall Chinook salmon that spawn in large mainstem rivers like the Hanford Reach and Snake River. The study was originally commissioned in FY 1994 and then recommissioned in FY 2000 through the Fish and Wildlife Program rolling review of the Columbia River Basin projects. The work described in this report covers the period from 1994 through 2004; however, the majority of the information comes from the last four years of the study (2000 through 2004). Results from the work conducted from 1994 to 2000 were covered in an earlier report.More than any other stock of Pacific salmon, fall Chinook salmon (Oncorhynchus tshawytscha) have suffered severe impacts from the hydroelectric development in the Columbia River Basin. Fall Chinook salmon rely heavily on mainstem habitats for all phases of their life cycle, and mainstem hydroelectric dams have inundated or blocked areas that were historically used for spawning and rearing. The natural flow pattern that existed in the historic period has been altered by the dams, which in turn have affected the physical and biological template upon which fall Chinook salmon depend upon for successful reproduction. Operation of the dams to produce power to meet short-term needs in electricity (termed power peaking) produces unnatural fluctuations in flow over a 24-hour cycle. These flow fluctuations alter the physical habitat and disrupt the cues that salmon use to select spawning sites, as well as strand fish in near-shore habitat that becomes dewatered. The quality of spawning gravels has been affected by dam construction, flood protection, and agricultural and industrial development. In some cases, the riverbed is armored such that it is more difficult for spawners to move, while in other cases the intrusion of fine sediment into spawning gravels has reduced water flow to sensitive eggs and young fry.Recovery of fall Chinook salmon populations may involve habitat restoration through such actions as dam removal and reservoir drawdown. In addition, habitat protection will be accomplished through setasides of existing high-quality habitat. A key component to evaluating these actions is quantifying the salmon spawning habitat potential of a given river reach so that realistic recovery goals for salmon abundance can be developed. Quantifying salmon spawning habitat potential requires an understanding of the spawning behavior of Chinook salmon, as well as an understanding of the physical habitat where these fish spawn. Increasingly, fish biologists are recognizing that assessing the physical habitat of riverine systems where salmon spawn goes beyond measuring microhabitat like water depth, ...

“…This was attributed to combined sewer overflows, including two source types: urban surface runoff [Driver and Troutman, 1989], and direct sewage sources released during event [Huber, 1993]. This is in contrast to the findings of Rose [2003] where urban surface runoff consisted of weakly concentrated waters. For the Dill catchment, the pulse of B in discharge was indicative of this first flush, and undermined the idea of continuously released sewage point sources.…”

The effect of catchment complexity on hydrologic and hydrochemical catchment response was characterized in the mesoscale Dill catchment (692 km2), Germany. This analysis was developed using multivariate daily stream concentration and discharge data at the basin outlet, in connection with less frequently sampled catchment‐wide end‐member chemistries. The link between catchment‐wide runoff sources and basin output was observed through a combination of concentration‐discharge (C‐Q) analysis and multivariate end‐member projection. Subsurface stormflow, various groundwater and wastewater sources, as well as urban surface runoff emerged in catchment output chemistry. Despite the identification of multiple sources, several runoff sources observed within the catchment failed to display consistent links with the output chemistry. This failure to associate known source chemistry with outlet chemistry may have resulted from a lack of hydraulic connectivity between sources and basin outlet, from different arrival times of subbasin‐scale runoff contributions, and also from an overlap of source chemistries that subsumed discrete runoff sources in catchment output. This combination of catchment heterogeneity and complexity simply suggests that the internal spatial organization of the catchment impeded the application of lumped mixing calculations at the 692 km2 outlet. Given these challenges, we suggest that in mesoscale catchment research, the potential effects of spatial organization should be included in any interpretation of highly integrated response signals, or when using those signals to evaluate numerical rainfall‐runoff models.
