Unmitigated urbanization frequently alters the flow frequency distribution and changes the source and transport rates of sediments in previously “in regime” channels. These changes may result in increased stream erosion, changes in alluvial mater

Summary Stream-habitat assessment for evaluation of restoration projects requires the examination of many parameters, both watershed-scale and reach-scale, to incorporate the complex non-linear effects of geomorphic, riparian, watershed and hydrologi

The applicability of the Qualitative Habitat Evaluation Index (QHEI) as a planning and design tool for stream assessments in southern Ontario was evaluated. QHEI assessments were made at 50 Ontario sites where benthic data were available or collected

A new method is developed to integrate empirical data and watershed properties with geographic information systems (GIS) tools to prioritize the sensitivities of streams to deterioration arising from adverse stormwater effects. A risk-based decision-

Since 1970, the design focus of urban stormwater systems has expanded from quick removal of stormwater to include control of peak flows (1970s) and removal of pollutants (1980s). The addition of stormwater ponds as control elements satisfied these tw

Maintaining the natural hydrologic variability of streamflows is critical for conserving stream ecosystems. The consequences for streamflow of gradual urbanization were investigated for a small Ontario watershed. A hydrologic model (GAWSER), calibrat

Vegetated filter strips (VFS) are used recently for removal, at or near the source, of sediment and sediment-bound chemicals from cropland runoff. Vegetation within the flowpath increases water infiltration and decreases water turbulence, thus enhanc

Calibrating a comprehensive, multi-parameter conceptual hydrological model, such as the Hydrological Simulation Program Fortran model, is a major challenge. This paper describes calibration procedures for water-quantity parameters of the HSPF version

Vegetated filter strips (VFS) are designed to reduce sediment load and other pollutants into water bodies. However, adaptation of VFS in the field has been limited owing to lack of data about their efficiency and performance under natural field condi

In this study we investigated the nitrate (NO3−–N) attenuating capabilities of two headwater stream riparian zones in southern Ontario. Peak concentrations of groundwater NO3−–N at sites adjacent the Speed River and Carroll Creek occurred in
