Twenty-eight coupled observations of flow, transport, and bed surface grain size distribution were made in a laboratory flume using a wide range of flows and a sediment with a very poorly sorted, bimodal grain size distribution. These observations permit the transport rates of individual size fractions to be scaled by the proportion of each size immediately available for transport on the bed su...

Fine waste management from quarry has been commonly the final disposal in mining tailings and as refilling material for landscape recovery areas already exploited. However, different uses of these wastes have studied, highlighting earth constructions because a new economic benefit is generated environmental impact reduced. Moreover, compared to cement constructions, are environmentally friendly...

Soil gravel content affects many soil physical properties, as well as crop yield. Little is known regarding the influence of soil gravel content on growth and nutrient uptake of durum wheat (Triticum durum Desf.). The accumulation of nitrogen and phosphorous during the vegetative and reproductive periods and the contribution of pre-anthesis assimilates to grain N and P content have been evaluat...

Soil moisture is a key variable in dryland ecosystems since it determines the occurrence and duration of vegetation water stress and affects the development of weather patterns including rainfall. However, the lack of ground observations of soil moisture and rainfall dynamics in many drylands has long been a major obstacle in understanding ecohydrological processes in these ecosystems. It is al...

the northern sector of the Kent interlobate Complex, created by two major ice lobes of the Laurentide ice sheet during late Wisconsinan times, dominates the glacial landscape of northeast Ohio. the geomorphology of this impressive complex reveals the presence of large hummocks, kettle lakes and substantial esker chains. the esker chains, usually smaller than 1.3 km long, run parallel to the int...

well as providing forest products. This study refers to the identification of the land reclamation areas and potential plantation areas on the Bagmati river-basin in the Terai region of Nepal, and recommends appropriate species for plantation in order to rehabilitate such areas. Multi-temporal Landsat Satellite Images (Landsat 7 and Landsat 8) were acquired for 2002 and 2014. Object-based Image...
