The Strickland River is the primary sediment source for the Fly River system, a large tropical river that ranks in the global top 20 for both water and sediment discharge. Over the past decade the Strickland sediment discharge has been gauged at many locations. Comprehensive studies are now underway to study the delivery, transport, and storage of sediment throughout this system. A key question...

Obesity and overweight in children and adolescents are one of the most serious public health challenges of the 21st century, such that increased more twofold fold from 20 years ago (1). The numbers have doubled Childhood Obesity as the global principal health problem is steadily involving many lowand middleincome countries, particularly within urban areas (2-5).Obesity is a principal risk-facto...

The aim of this paper is to assess the change detector r specifically elaborated to analyse ENVISAT ASAR Wide Swath Mode (WSM) data pairs for plain flood changes detection. The algorithm relies on an enhanced ratio for strong changes over large homogeneous and flat areas combined with a ratio calculated from the two raw images. The change detection assessment was conducted on 14 image pairs exp...

A portion of Arizona's San Pedro River is managed as a National Riparian Conservation Area but is potentially affected by ground-water withdrawals beyond the conservation area borders. We applied an assessment model to the Conservation Area as a basis for monitoring long-term changes in riparian ecosystem condition resulting from changes in river water availability, and collected multi-year dat...

land use management policy and method are two important factors in usage of land by human. in this regard, evaluation of environmental capability would serve as a valuable basis for the best use practice of soil and water resources in addition to the reduction in environment consequences of the projects. in the correct study, the environmental capability of birjand plain, located in the south k...

Groundwater quality regarding major anions and cations in the Birjand Plain located in the largest desert in Eastern Iran was monitored in this study. Fifteen boreholes were considered as sampling stations and the parameters pH, TDS, EC and major anions and cations were measured in groundwater samples. The dominant groundwater types can be introduced as sodium-chloride and magnesium-sulphate. T...

The Techa river was contaminated in 1949-1956 from the nuclear enterprise "MAYAK". The investigations were carried out in flood plain of the Techa river in 1992-1999. In the upper and middle parts of the river the basic contaminator is I 3 7 Cs; downstream more active is 9 0 Sr. Density of contamination of soils with 9 0 Sr down the river changes from 600 to 200 kBq/m , and that with 1 3 7 Cs f...
