“…This may be a contributing factor to flood cases in the study area. Land use and floods are closely related; therefore, any changes in the land use, such as urbanization across the catchment's area, may trigger a sequence of flood occurrences (Hadjimitsis, 2012). The current and future development in water resources is very sensitive to land use and intensification of human activities.…”

In recent times, the swift and uncoordinated urban expansion in the medium sized city of Osogbo has increasingly encroached on the environmental sensitive areas. This uncoordinated exploitation of the ecological fragile areas for urban development has triggered urban flooding, which poses serious threat to human lives and properties in the city. This study therefore utilized geospatial technologies to generate flood hazard model for medium sized cities in developing countries in general and Nigeria in particular with a view to identifying hotspots and providing measures to forestall flood occurrences. The study used Shuttle Radar Topography Mission-Digital Elevation Model (SRTM-DEM), Landsat 7-2000 and Operational Land Imager 8 (OLI)-2015 images. Multi-criteria evaluation method was used to derive the physical characteristics of watersheds from the data to delineate the areas vulnerable to flooding. Flood inundation characteristics were simulated using Hydrologic Engineering Centre-River Analysis System (HEC-RAS) model with GIS interface and found discharge of over 500 m 3 /s for the 100-year profile period to be high, given the size of the analyzed basin (207.41 km 2). The flood hazard map showed that 3.92, 103.38 and 100.11 km 2 were least, moderately and highly vulnerable areas respectively. Most prone areas were built-ups with high impervious surface in the basin area where floodplain traversed high and moderate vulnerability zones. The study advocates consistent use of dynamic model within GIS for floodplain delineation and management planning to reduce the flood hazards.

“…According to this conception, a considerable shift has been observed from structural defense against floods to a more comprehensive approach including appropriate land use, agricultural and forest practices [1,2,3]. Land cover changes, may be used to describe dynamics of urban settlements and vegetation patterns as an important indicator of urban ecological environments [4].…”

Monitoring urban land cover with the use of satellite remote sensing techniques as a means of flood risk assessment in Cyprus

The increase of flood inundations occurring in different regions all over the world has enhanced the need for effective flood risk management. A flood can be determined as a mass of water that produces runoff on land that is not normally covered by water. This study strives to highlight the need of digital mapping of urban sprawl in a catchment area in Cyprus and the assessment of its contribution to flood risk. The Yialias River (Nicosia, Cyprus) was selected as case study where devastating flash floods events took place at 2003 and 2009. In order to search the diachronic land cover regime of the study area multi-temporal satellite imagery was processed and analyzed, (ASTER). A classification model is proposed based on spectral, texture and shape features in order to create efficient land use and land cover maps. GIS were used to detect identifying trends, both visually and statistically, resulting from land use changes in a flood prone area such as Yialias by the use of spatial metrics. The results indicated that there is a considerable increase of urban areas cover during the last 10 years. All these denoted that one the main driving force of the increasing flood risk in catchment areas in Cyprus is generally associated to human activities.

“…These corrections could improve the efficiency of water use. Lastly, Hadjimitsis (2010) used remotely sensed imagery, historical hydrological data and meteorological data to examine the linkage between the change in land use and cover, on the one hand, and flood risk, on the other hand, in an urban area in Cyprus, over the past 45 years. Results showed a tremendous urban development in the area under study that had a significant impact on the respective catchment areas.…”
