Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

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...

Aim To test six hypotheses that could explain or mediate the positive correlation between human population density (HPD) and bird species richness while controlling for biased sampling effort. These hypotheses were labelled as follows: productivity (net primary productivity, NPP); inherent heterogeneity (diversity of vegetation types); anthropogenic heterogeneity (diversity of land uses); conse...

This paper provides a description of the methodologies and processes used for the creation of a decision/support model for land acquisition decisions on a cooperative open space project between the City of Bakersfield and other local agencies. The model uses a cost/benefit approach using components of habitat ranking, developed through an independently prepared evaluation, and estimated per acr...

A key part of the strategy to manage the problems of flooding and sedimentation of the lower Yellow River in China is the control of soil erosion on the loess plateau. Land use practices are assumed to be the root cause of the high sediment yield and therefore able to be controlled. An analysis of the geomorphology of the loess plateau region shows that there are natural causes of high sediment...

An assessment of four different remote sensing based methods for deriving digital elevation models (DEMs) was conducted in a floodprone watershed in North Carolina. New airborne LIDAR (light detecting and ranging) and IFSAR (interferometric synthetic aperture radar (SAR)) data were collected and corresponding DEMs created. These new sources were compared to two methods: Gestalt Photomapper (GPM...

The lowermost Mississippi River, defined herein as the river segment downstream of the Old River Control Structure and hydrodynamically influenced by the Gulf of Mexico, extends for approximately 500 km. This segment includes a bedrock (or more precisely, mixed bedrock-alluvial) reach that is bounded by an upstream alluvial-bedrock transition and a downstream bedrock-alluvial transition. Here w...
