Geographic Information System (GIS) techniques are being increasingly and effectively used in morphometric analysis and groundwater potentiality mapping of drainage basin owing to its capabilities of manipulation, analysis, flexibility of experimentation and ability to extract topological attributes from various thematic maps, and to work as a unique tool for geospatial modelling. An attempt to...

The northern peninsular of Malaysia has lost a lot of lives and property worth billions to the series of floods that have been occurring for many years. Many disaster management strategies have been adopted by the Malaysian government in handling these flood disasters but it is still a topic in the annual agenda. This research project aimed at using fusion techniques in order to obtain more int...

Reliable water surface extraction is essential for river delineation and flood monitoring. Obtaining such information from fine resolution satellite imagery has attracted much interest for geographic and remote sensing applications. However, those images are often expensive and difficult to acquire. This study proposes a more cost-effective technique, employing freely available Landsat images. ...

Lidar data have become a major source of digital terrain information for use in many applications including hydraulic modeling and flood plane mapping. Based on established relationships between sampling intensity and error, nominal post-spacing likely contributes significantly to the error budget. Post-spacing is also a major cost factor during lidar data collection. This research presents met...

Delineating the flood extent using SAR data has been an unexceptional activity since launch of first sensors. The methodologies applied to image classification vary in complexity and accuracy and, for Sentinel-1, technical procedures must be adapted considering their polarization, band, temporal resolution, other factors. Considering these aspects, this article aimed realize a systematic litera...

An integrated framework was employed to develop probabilistic floodplain maps, taking into account hydrologic and hydraulic uncertainties under climate change impacts. To the several scenarios representing individual compounding effects of models’ input parameters uncertainty were defined. Hydrologic model calibration validation performed using a Dynamically Dimensioned Search algorithm. A gene...

A flood frequency analysis is conducted using instantaneous peak flow data over a hydrologic sub-region of southern Québec following three distinct methodological frameworks. First, the locally available data. Second, daily processed in order to consider effect. Third, regional pooling all study area. Results reveal notable diversity resulting recurrence estimates and related uncertainties from...
