“…However, due to the unavailability of soil type with acceptable spatial resolution in the study area, the study failed to use soil type as a factor. Not until recently, Nkwunonwo et al (2020) proposed a soil map for Nigeria from 1985 reconnaissance soil survey. Overtime, due to anthropogenic and non-anthropogenic activities a soil survey of 1985 and completed in 1990 must have change in properties and characteristics.…”

The increased flood incidences experienced all over the world due to climate change dynamics call for a concerted effort towards forestalling future hazards. This study thus, identified the areas that are susceptibility to floods in parts of the Makera district of the Kaduna South Local Government Area in Nigeria using geospatial techniques. Geographic Information System (GIS) was used to produce thematic layers of the factors contributing to flooding (elevation, slope, drainage density, rainfall, land use/land cover); and a multi-criteria evaluation particularly the “Analytical Hierarchical process” (AHP) was applied to determine the locations at risk. The various thematic layers were integrated into the weighted overlay tool in the ArcGIS 10.3 environment to generate the final susceptibility map. The overlay tool was also used to determine the elements at risk of flood in the study area. The results show that the areas that were highly susceptible to flood constituted about 39% of the study area, while moderate and low vulnerable areas constituted about 26% and 35%, respectively. The result of the multi-criteria analysis revealed that land use/land cover (0.601) was the factor that contributed the most to flooding in the study area based on the criteria weights followed by rainfall (0.470), drainage density (0.326), elevation (0.144), and slope (0.099), respectively. The study recommends that authorities concerned should ensure strict adherence to land use planning act, such that floodplains are avoided during development of any type.

“…On a final note, the study recommends that future studies uses soil type of high spatial and temporal resolution. This can be done by fusion of International Soil Reference and Information Centre (ISRIC) data (https://data.isric.org/geonetwork/) and that of Nkwunonwo et al (2020).…”

The use of ArcGIS for geospatial analysis is vital as the first step in earth research. The research focused on Sendang Biru Beach, Tambak Rejo Village, Malang Regency, East Java Province, Indonesia. Based on the analysis of topographic, geological, and land use data, Sendang Biru Beach is located in a basin to a hill with an average height of 125 masl. Geologically, it is located in the Wonosari Formation, flanked by the Qas (swamp and river deposits) and the Tomm (Mandalika Formation). Furthermore, land use is dominated by dry forests. The basin is used for plantations, settlements, and scattered fields and has a karst aquifer flowing all year round, including springs that have diffuse and fissure channel types. The water quality in the area is still within normal limits, has not experienced contamination of seawater intrusion. Sendang Biru Beach Land in Tambak Rejo Village, the ideal development is directed at Fisheries and Coastal Tourism, supported by the presence of extensive dry forest land, karst aquifer resources, and the existence of Sempu Island as a nature reserve.
