Riverine ecosystems are linked to their watersheds, and both land use and physiographic environmental conditions influence nutrient dynamics and water quality. We assessed aquatic nutrients and their relationship with land use and physiographic conditions at multiple spatial scales in the Brazos River watershed (Texas, USA) to examine the interactions between land use and physiography and their...

Rates of poverty and economic inequality in rural Alabama are among the nation's highest increasing agricultural productivity can provide a needed boost to these communities. The transition from rain-fed irrigation-fed (RFtoIF) agriculture has significantly increased farm profitability elsewhere United States. Despite this potential enhance stability resilience economies, irrigated cropland acc...

Savannah floodplains are a natural agroecosystem located in the eastern plains of Colombia, with soils considered to be low fertility. This assumption has not been rigorously validated by direct experimental studies. The aim study was analyze soils’ physicochemical characteristics “banks” and “lows”, which physiographic positions, from floodplain savannah Arauca, Colombia. Soil samples were col...

[1] The southern flanks of the central Nepalese Himalaya correspond to a sharp transition in landscape morphology and bedrock mineral cooling ages that suggests a change in rock uplift rate. This transition can be explained by either (1) accretion of footwall material to the hanging wall across a ramp in the décollement separating India from Eurasia, thereby enhancing rock uplift rates above th...

Eighteen low flow indicators are considered in the research of sixteen hydrological stations Juzna Morava river basin. The estimated by statistical analysis and grouped as environmental indicators. A crosscorrelation between all is assessed. Environmental flows at hydrologic obtained GEP method. transferred to two small ungauged basins regression with physiographic characteristics. adjustment p...
