TLDR
In this article, a rapid mapping method has been developed to derive urban development over five time periods between 1886 and 1995 from scanned Ordnance Survey historical maps, and the resulting map of urban development in Worcester (scale 1:20,000) shows that almost half of the recorded pluvial flood incidents occurred in areas built up between 1956 and 1975, which contradicts local belief that an outdated (Victorian) drainage system causes most of the problems.Abstract:
Between 2004 and 2008 the city of Worcester, UK experienced a number of pluvial flood events. The causes of this kind of flooding are the topic of ongoing research. This paper describes a study that aimed to investigate the urban development of Worcester over time in relation to the location of recorded pluvial flood incidents. A novel rapid mapping methods has been developed to derive urban development over five time periods between 1886 and 1995 from scanned Ordnance Survey historical maps. The technique compared well with manual digitization results with k-hat values ranging from 0.67 to 0.87 for the land use maps created for different time periods. The technique performed least well for the oldest map series, due to misclassification of the abundant symbols and annotation. The method will be particularly beneficial for investigation of town/city development in time over large areas. The resulting map of urban development in Worcester (scale 1:20,000) shows that almost half of the recorded pluvial flood incidents occurred in areas built up between 1956 and 1975, which contradicts local belief that an outdated (Victorian) drainage system causes most of the problems. The quality of the post World War II developments is more likely to be a source for concern.read more

Szymon Szewrański,Jakub Chruściński,Jan Kazak,Małgorzata Świąder,Katarzyna Tokarczyk-Dorociak,Romuald Żmuda +5 more
TL;DR: The Pluvial Flood Risk Assessment Tool (PFRA) as mentioned in this paper combines information about land cover, soils, micro-topography (LiDAR data), and projected hydro-meteorological conditions to identify the spatial and temporal distribution of pluvial flood risks in newly developed areas.

A remote sensing based integrated approach to quantify the impact of fluvial and pluvial flooding in an urban catchment
TL;DR: This is the first time that remote sensing data, hydrological modelling and flood damage data at a property level have been combined to differentiate between the extent of flooding and damage caused by fluvial and pluvial flooding inthe same event.

Spatial Metrics and Image Texture for Mapping Urban Land Use
TL;DR: In this paper, the spatial metrics and texture measures are used to describe the spatial characteristics of land-cover objects within each land-use region as derived from interpreted aerial photographs, and a detailed land use map with nine categories was derived for the Santa Barbara South Coast Region area.
