negative impacts of gully erosion in marly areas are severe due to improper landuse practices such as irrigation, tillage, overgrazing and degradation of vegetation cover. the objective of this research was to evaluate gully thresholds related to plant vegetation cover and landuse change in the agriculture (ag), fair rangeland (fr) and weak rangeland (wr) areas of ghaasr-e-shirin, kermanshah, i...

1. To prepare various thematic layers such as drainage density, lineament density, slope, lithology, geomorphology and landuse/land cover using SOI topographical maps, remote sensing data and GIS. 2. To prioritize the weightages of individual themes and feature score depending upon their suitability to hold groundwater. 3. To prepare the integrated final groundwater potential map (GPM) using th...

Spatial discontinuity often causes poor accuracy when a single model is used for the surface modeling of soil properties in complex geomorphic areas. Here we present a method for adaptive surface modeling of combined secondary variables to improve prediction accuracy during the interpolation of soil properties (ASM-SP). Using various secondary variables and multiple base interpolation models, A...

BACKGROUND & OBJECTIVES Malaria is a serious disease which has repeatedly threatened Andaman, an island territory of India. Uncharted dense vegetation and inaccessibility are the salient features of the area and the major areas are covered by remotely sensed data to identify the malaria vector's natural habitat. The present investigation appraises the role of geospatial technologies in identify...

Human population growth and development have degraded freshwater ecosystems through direct negative effects on basal resources and higher trophic levels. Knowledge of how basal resources are influenced by anthropogenic activities is needed to examine foodweb responses and to evaluate negative effects of human disturbance. We combined quantitative sampling of all putative resources and consumers...

prioritization of sub-watersheds is very important in the natural sources and watershed management. in this study, the morphometric parameter and landuse changes using rs and gis techniques used in order to identify erosion-prone sub-watersheds. the morphometric parameter such as basin relief, the linear parameters (drainage density, bifurcation ratio, length of overland flow, stream frequency ...
