“…For example, the UK's 1975 Flood Studies Report [National Environment Research Council, 2002] was able to detect the effect on flood flows of urbanization (simply represented in a regional unit hydrograph analysis by the urban extent of a catchment). And, one of the earliest applications of continuous simulation hydrological modeling was to investigate effects of urbanization on stream flows in California [James, 1965]. While representation of agricultural land management remains problematic [McIntyre et al, 2013], simulation methods can, in principle, represent the physical effects of human activities on flood hazard as discussed above.…”

Socio-hydrology views human activities as endogenous to water system dynamics; it is the interaction between human and biophysical processes that threatens the viability of current water systems through positive feedbacks and unintended consequences. Di Baldassarre et al. implement socio-hydrology as a flood risk problem using the concept of social memory as a vehicle to link human perceptions to flood damage. Their mathematical model has heuristic value in comparing potential flood damages in green versus technological societies. It can also support communities in exploring the potential consequences of policy decisions and evaluating critical policy tradeoffs, for example, between flood protection and economic development. The concept of social memory does not, however, adequately capture the social processes whereby public perceptions are translated into policy action, including the pivotal role played by the media in intensifying or attenuating perceived flood risk, the success of policy entrepreneurs in keeping flood hazard on the public agenda during short windows of opportunity for policy action, and different societal approaches to managing flood risk that derive from cultural values and economic interests. We endorse the value of seeking to capture these dynamics in a simplified conceptual framework, but favor a broader conceptualization of socio-hydrology that includes a knowledge exchange component, including the way modeling insights and scientific results are communicated to floodplain managers. The social processes used to disseminate the products of socio-hydrological research are as important as the research results themselves in determining whether modeling is used for realworld decision making.

“…It was also assmned from his desc:ription of the area that "urban" could be expressed as 50 percent sewered and 20 percent impervious. James (1965) analyzed runoff dat~. from a 44-sq-mi basin south of Sacramento, Calif., within which 12 sq mi had been urbanized.…”

“…The :first is a slight modification of a method previously used by several investigators, especially D. G. Anderson (1968) and L. D. James ( 1965) . The percentage of an area sewered is plotted against the percentage of the area rendered impervious by urbanization; isopleth lines (lines of equal value of the ratio) on the graph show the ratio of peak discharge under urbanized conditions to the peak discharge under rural or unurbanized conditions.…”

“…There is extensive literature and a well-established knowledge on how urban development affects basin hydrology, hydraulic conditions of channels and floodplains, as well as flood discharges and frequency [8][9][10][11]. In several cases, poorly planned development carried out to accommodate fast population increase has caused substantial changes in local hydrology and natural drainage networks [12].…”

This work focuses on the spatial evolution of urban flooding phenomena in Athens metropolitan area, in Greece. The study examines the locations of flood-related damages and fatalities in Athens in 1880-2010, in comparison with the city's evolution, to identify possible changes in their spatial distribution. GIS software was used to develop a spatio-temporal database storing information on the location and timing of these flood-related incidents. The database was then used to determine and quantify spatio-temporal changes of flooding in the city. Results showed a gradual migration of areas subject to flooding from the central to the western part of Athens and finally to the northwestern and southern suburbs. This migration was accompanied by a significant increase of incidents in the newly built parts of the city and a simultaneous decrease at the oldest parts, following closely the city's spatial expansion over the study period. In addition, the study was able to identify and delineate particular parts of the city that experienced an increasing trend of flood incidents during the last decades and should be given priority in future flood risk mitigation actions.
