Abstract Modelling soil erosion and sediment transport are vital to assess the impact of flash floods. However, limited research works have studied transport, especially in Egypt. This paper employs HEC-HMS lumped hydrological model predict load due flood event 9th March 2014 Wadi Billi, The Modified USLE has been used calculate total upland erosion, while Laursen-Copeland simulate streams’ pot...

The objective of this work is to conduct a detailed mapping the Héðinsdalsjökull foreland, northern Iceland (65°39′N, 18°55′W). This cirque currently shows variety glacial and periglacial landforms derived from complex deglaciation. Mapping was performed combining traditional hand-drawn digital mapping. A sketch georeferenced in ArcMap 10.7.1, supported on an aerial photograph (year 2000). Its ...

Djebahia is an average city in the Algerian centre, reported to have many risks related landslides, with very important indices of instabilities. The recurrence damaging events this locality has shown fragility its urban system. main objective article analyse vulnerability municipality by determining physical condition structure. procedures for analysis factors at origin risk are mainly derived...

The urbanization and climate change phenomena are global problems whose negative effects have been exacerbated in cities, they a reason for the formation of warming urban heat islands. research came to shed light on expansion Baghdad four decades which extended between (1981-2021) using ArcMap Gis10.7 technique, then evaluating impact this city’s climate. data were taken from station by remote ...

An ideal situation for a country or region will be to have a spatial data infrastructure (SDI) containing the datasets and models necessary to support all the planning and decision processes. Often, especially in developing countries, this is not the case. Can governments take good and valid decisions in cases where the available SDI is not capable of having all the datasets or models required ...

Centralized data storage and data exchange is a key issue in many interdisciplinary research projects that focus on environmental field studies and regional modelling on various scales. Furthermore, the overall success of such projects depends on a well organized and prepared graphical representation of spatial project data within web mapping applications. In this contribution, we introduce the...

SDMtoolbox 2.0 is a software package for spatial studies of ecology, evolution, and genetics. The release of SDMtoolbox 2.0 allows researchers to use the most current ArcGIS software and MaxEnt software, and reduces the amount of time that would be spent developing common solutions. The central aim of this software is to automate complicated and repetitive spatial analyses in an intuitive graph...

BACKGROUND The Institute of Medicine recommends that public health agencies restrict the number and regulate the location of tobacco retailers as a means of reducing tobacco use. However, the best policy strategy for tobacco retailer reduction is unknown. PURPOSE The purpose of this study is to test the percent reduction in the number and density of tobacco retailers in North Carolina resulti...

This study aimed to determine the impact of land use and illegal activities on elephant distributions in 2003, 2015, 2021. Geospatial data inclusion satellite images different characteristics were used as well aerial count animals along linear transects varying widths. Using ArcMap 10.8, we laid grilles 100 km 2 covering entire area. We performed clipping display estimate area elephant’s occupa...

The article discusses the possibilities of assessing state river beds and changes in them using remote sensing technologies (RS) geographic information systems (GIS). With help geoinformation technologies, an assessment deformation phenomena over past 25 years channel Sokh river, which was chosen as object research, given. Channel have been studied data obtained from satellites. To analyze situ...
