...More recently, Smith et al. (2015) developed a framework for real-time flood mapping using social media data, demonstrating that even a small amount of georeferenced tweets could produce promising results....

...Social media capture microlevel, real-time information using “citizen-as-sensors” during a flood and have been increasingly utilized for both collecting and disseminating localized information during natural disasters (Smith et al., 2015)....

...On the other side, various crowdsourcing data (e.g. Flickr, citizen science, Twitter) come with less controlled quality assurance, but are timely....

...Although the experiments here exploit geotagged images sourced from social media, the rapid inundation mapping methodology employed could incorporate other crowdsourced assessments such as Twitter (Panteras et al. 2014; Smith et al. 2015) or volunteered by citizens (Poser et al. 2009)....

...Consequently, the explicit models are constrained by the Courant–Friedrichs–Lewy condition (Courant et al., 1967), which is a function of the largest velocity within the domain and the cell dimensions; accordingly, if the cell resolution of these models is halved, the simulation run-time can be expected to increase by approximately eight times....

...Clear evidence exists that social media is increasingly used as a tool for dissemination and communication during times of crisis and natural disasters, such as during the 2011 Queensland flood and Thai flood (Starbird et al., 2010; Vieweg et al., 2010; Kongthon et al., 2012; Murthy and Longwell, 2012); the accuracy and validity of information provided by the public through social media such as Twitter however may be questionable....

...Comparison of locations geocoded from the text within Tweets against the actual location of the user from geotags suggests even when Tweets are geotagged, this data can rarely be considered reliable for inferring flooded locations (Leetaru et al., 2013)....

...Steep slopes and narrow gaps can induce supercritical flow conditions, resulting in such phenomena as hydraulic jumps, and thus requiring shock-capturing but computationally intensive models if they are to be accurately reproduced (Mignot et al., 2006)....
