What is Urban Hydrology and Impervious Surfaces?

Urban Hydrology and Impervious Surfaces studies the alteration of peak flows, baseflows, and erosion risks due to impervious cover in urban watersheds using models like SWMM and HEC-HMS.

Impervious surfaces from urbanization increase runoff volumes and peak flows while reducing infiltration and baseflows. Researchers quantify these effects through hydrological modeling and remote sensing of land cover changes. Over 10 key papers, including Fletcher et al. (2012) with 945 citations, review modeling approaches and impacts on receiving waters.

Key Challenges

Why It Matters

Urban hydrology models predict stream degradation from impervious expansion, guiding stormwater infrastructure design in cities. Fletcher et al. (2012) link impervious cover to receiving water quality declines, informing regulatory limits on development density. McGrane (2015) quantifies hydrological shifts for water quality management, while Salvadore et al. (2015) highlight SWMM applications for urban catchment planning. Yang et al. (2003) enable impervious mapping for watershed-scale predictions, supporting resilience against floods.

Key Research Challenges

Accurate Impervious Mapping

Remote sensing struggles with sub-pixel impervious detection in heterogeneous urban areas. Yang et al. (2003) synergize Landsat and high-resolution imagery but note accuracy limits over large areas. Calibration remains challenging for mixed land covers.

Model Calibration at Scale

SWMM and HEC-HMS require extensive data for large urban catchments. Barco et al. (2008) demonstrate automatic calibration for Ballona Creek using GIS inputs. Parameter uncertainty persists in data-sparse regions.

Predicting Baseflow Alterations

Urbanization reduces infiltration, altering baseflows and groundwater recharge. Fletcher et al. (2012) review consequences for receiving waters but identify gaps in long-term modeling. McGrane (2015) notes insufficient integration of land use dynamics.
