Enabling high-quality observations of surface imperviousness

High-quality observation of surface imperviousness for urban runoff modelling using UAV imagery

UAV-based mapping of surface imperviousness for water runoff modelling

Modelling rainfall-runoff processes in urban catchments has become an increasingly relevant issue, for instance to estimate the risk associated with urban flooding in densely populated areas. This needs hydrological models which, besides rainfall information, require good input data of detailed surface characteristics, such as imperviousness to accurately predict rainfall-runoff. One way to obt...

Evaluation of Urbanization Influences on Urban Climate with Remote Sensing and Climate Observations

Remote sensing data were utilized to assess urban land cover and its thermal characteristics through mapping sub-pixel impervious surfaces and assessing thermal infrared images. Landsat imagery was used to calculate variation in urban imperviousness from 1995 to 2002 in the Tampa Bay watershed, Florida. The urban-rural boundary and urban development density were defined by selecting certain imp...

Impacts of urbanization on stream habitat and fish across multiple spatial scales.

We analyzed the relation of the amount and spatial pattern of land cover with stream fish communities, in-stream habitat, and baseflow in 47 small southeastern Wisconsin, USA, watersheds encompassing a gradient of predominantly agricultural to predominantly urban land uses. The amount of connected impervious surface in the watershed was the best measure of urbanization for predicting fish densi...

Development of a Population Density and Land Use Based Regression Model to Calculate the Amount of Imperviousness

Nonpoint source pollution has been cited as the nation’s number one water quality problem and urban runoff is the pollutant of greatest concern. It has been noted that the amount of urban runoff and its impacts on stream conditions and water quality are correlated to anthropogenic watershed imperviousness. While much research has focused on quantifying this relationship, little work has been do...
