Understanding the different background landscapes in which malaria transmission occurs is fundamental to understanding malaria epidemiology and to designing effective local malaria control programs. Geology, geomorphology, vegetation, climate, land use, and anopheline distribution were used as a basis for an ecological classification of the state of Roraima, Brazil, in the northern Amazon Basin...

water plays a vital role in the development of activities in an area. the surface water resources are inadequate to fulfill the water demand. productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...

Groundwater depletion is one of the most critical concerns for users and policymakers. Identifying groundwater potential (low to high) helps properly plan available resource. This study has used possibilities a geographical information system (GIS), remote sensing and, course, field data delineate zones in Chennai River Basin (CRB). Thematic layers generated eleven controlling factors, such as ...

Groundwater is critical to the socioeconomic development of any region. Infiltration surface water into ground influenced by a variety factors such as soil pores, folds, fractures, faults, and joints, all which contribute groundwater recharge. an important source freshwater in drought-prone Pudukkottai district Tamil Nadu, India. Therefore, search for potential zones (GWPZs) critical. The prese...

Terrestrial Laser Scan (TLS) data are seeing increasing use in geology, geomorphology, forestry and urban mapping. The ease of use, affordability and operational flexibility of TLS suggests that demand for it is likely to increase in large scale mapping studies. However, its advantages may remain restricted to specific environments, due to difficulties in defining bare-ground level in the prese...

Mons Rümker is a large volcanic complex in Oceanus Procellarum on the Moon and is a candidate landing site for China’s Chang’E-5 sample return mission. We conducted a comprehensive study of the topography, geomorphology, composition, and stratigraphy of the Mons Rümker region with multisource remote sensing data in order to better understand the geology of the region and provide further support...

Slope instability research and susceptibility mapping is a fundamental component of hazard management in decreasing the risk of living with landslides. Landslide susceptibility is defined as the proneness of the terrain to produce slope failures and susceptibility is usually expressed in a cartographic way. The Dena city in Iran is a landslide prone zone because of its own characteristics inclu...

Interacting river discharge, tidal oscillation, and tropical rainfall across the 22,000 km Orinoco delta plain support diverse fresh and brackish water ecosystems. To develop environmental baseline information for this largely unpopulated region, we evaluate major coastal plain, shallow marine, and river systems of northeastern South America, which serves to identify principal sources and contr...
