Declines in cottonwood (Populus spp.) recruitment along alluvial reaches of large rivers in arid regions of the western United States have been attributed to modified flow regimes, lack of suitable substrate, insufficient seed rain, and increased interspecific competition. We evaluated whether and how these factors were operating during 1993–1996 to influence demographics of Fremont cottonwood ...

the appearance of sowbugs (hemilepistus shirazi schuttz) in the sedimentation basins of the artificial recharge of groundwater (arg) systems in the gareh bygone plain (gbp) in southern iran is considered an ecological breakthrough in desertification control. this study was performed at the kowsar floodwater spreading and aquifer management research, training and extension station in gbp, 200 km...

Introduction: We have previously demonstrated the viability of using thermal infrared images for mapping surface grain size distributions on terrestrial allu-vial fans [1, 2, 3]. For a well characterized alluvial fan in Owens Valley, CA we have used a quantitative analysis between aerial thermal images and ground-based grain size counts as well as a qualitative analysis between our thermal imag...

This study examines the spatial distribution of the organic carbon found in alluvial soils affected by successive floods. In flood zones, very little is known of the processes associated with the development of soils subjected to frequent flooding, in particular with respect to the accumulation of litter and organic carbon concentrations. The aim of this study is to better understand the distri...

Field studies were established on the alluvial floodplain soils in Louisiana, from 2013 to 2015, to evaluate the effect of silicate slag applications on productivity of wheat (Triticum aestivum), under sufficient and high nitrogen (N) application rates. Treatments were arranged in a randomized complete block design, with four replications consisting of twelve treatments: a factorial combination...

Irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. This experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (K) with that of di...

The study was conducted in January 2020 at the Indragiri Tembilahan Islamic University experimental garden, aimed to find out influence of combination alluvial soil and peat as a planting medium on growth production onions (Allium ascollanicum L), best for (Alluium ascalonicum L). research design used is non-factorial randomized group (RAK) design, consisting 7 treatments 3 repeats. A0 = Peat S...

Soil erosion and sedimentation processes can be considered as serious eco-environmentalproblems. This study aimed to estimate the basin-wide erosion using the Revised UniversalSoil Loss Equation (RUSLE). The soil erosion parameters included rainfall erosivity mapgenerated from the rainfall data, soil erodibility extracted from the soil map, land cover andmanagement map produced from supervised ...

Local surface water and stormflow were infiltrated intermittently from a 40-ha basin between September 2003 and September 2007 to determine the feasibility of recharging alluvial aquifers pumped for public supply, near Stockton, California. Infiltration of water produced a pressure response that propagated through unconsolidated alluvial-fan deposits to 125 m below land surface (bls) in 5 d and...
