Groundwater is important when there an insufficient spring water supply for daily needs. The population growth and expansion of the cities demand more water. Thimphu capital city Bhutan facing shortage in recent times due to urban growth. This study aims find potential area groundwater using Fuzzy Analytic Hierarchy Process. factors used this are elevation, slope, curvature, topographic wetness...

The correlation between climate change and pine tree dieback must be understood to implement a proactive forest management system. In this study, an ensemble model combining random forest, the generalized boosting model, linear was used analyze topographical environmental characteristics of trees suffering from in Wangpicheon Ecosystem Landscape Conservation Area, areas which are at risk were e...

This paper presents a machine learning method to map groundwater potential in crystalline domains. First, spatially-distributed set of explanatory variables for occurrence is compiled into geographic information system. Twenty classifiers are subsequently trained on sample 488 boreholes and excavated wells region eastern Chad. process includes collinearity, cross-validation, feature elimination...

In recent decades, floods have been the most common, complex, and destructive natural calamities worldwide. Hence, for inclusive flood risk assessment, creating susceptibility mapping to demarcate flood-vulnerable zones is fundamental decision makers. To assess flood-prone locations in Akre, Iraqi Kurdistan Region, was undertaken using geographic information systems, remote sensing, an analytic...

In the last years satellite remote sensing applications in hydrology have considerably progressed. A new multi-temporal satellite data-analysis approach has been recently suggested in order to estimate space-time changes of geophysical parameters possibly related to the increase of environmental and hydro-geological hazards. Such an approach has been already used both for flooded area mapping (...

The capability of active microwave remote sensing to measure soil moisture was validated via the use of GIS techniques incorporating soil landscape unit assessment and terrain wetness. The work was carried out over an 80 km region in the Mount lofty Ranges in South Australia. Search for atypically wet sites (ie. wet areas in a dry landscape, which were non-irrigated) was completed using analysi...

In this study, geographic information system (GIS)-based, analytic hierarchy process (AHP) techniques were used to identify groundwater potential zones provide insight decisionmakers and local authorities for present future planning. Ten different geo-environmental factors, such as slope, topographic wetness index, geomorphology, drainage density, lithology, lineament rainfall, soil type, thick...
