Prioritizing Vegetative Buffer Strip Placement in an Agricultural Watershed
AGNPS Buffer Strips Sediment Geographic Information System GIS
2015/8/6
In this study, the Agricultural Nonpoint Source Pollution Model (AGNPS) was used to determine locations of vegetative buffer strip effectiveness on reducing sediment load within the East Bad Creek (EB...
Runoff formation in a tile-drained agricultural basin of the Harz Mountain Foreland, Northern Germany
hydrograph separation hydrological tracers isotopes dyes groundwater drain sampler
2015/2/4
By taking two different tile-drained agricultural basins with porous aquifers in the lowlands of northern Germany as examples, it is demonstrated with an integrated study approach that this type of ba...
Remote sensing & GIS applications for drainage detection and modeling in agricultural watersheds
Remote Sensing GIS
2015/1/16
The primary objective of this research involves mapping out and validating the existence of sub surface drainage tiles in a given cropland using Remote Sensing and GIS methodologies. The process is de...
Nitrous oxide emission from riparian buffers in agricultural landscapes of Indiana
Nitrous oxide riparian agriculture denitrification
2015/1/16
Riparian buffers have well documented capacity to remove nitrate (NO3-) from runoff and subsurface flow paths, but information on field-scale N2O emission from these buffers is lacking. This study mon...
An interface of drainage division for modeling wetlands and riparian buffers in agricultural watersheds
Drainage division DEM Geographic Information System
2015/1/7
In a complex watershed, isolated wetlands, riparian wetlands and riparian buffers provide important functions such as flood attenuation and water quality improvement. For conservation purposes, it is ...
Estimating sediment yield using Agricultural Non-Point Sources (AGNPS) model: The effects of slope information from different GIS softwares
Geographical Information System GIS slope information Sediment yield AGNPS model tropical catchment
2015/1/4
This study compares the effects of slope information derived from three GIS software on sediment yield as estimated using AGNPS model. The three GIS software are IDRISI for Windows, ERDAS Imagine and ...
DERIVING LAND COVER OF A LARGE AGRICULTURAL WATERSHED FROM MULTI-TEMPORAL LANDSAT SCENES
Agricultural NonPoint Source Pollution large watersheds Thematic Mapper hydrologic models
2009/10/13
Determining land-cover characteristics of large watersheds for use in hydrologic models has been enhanced by application of remotely sensed data and the technologies used to interpret them. The object...
Multi-objective calibration of a surface water-groundwater flow model in an irrigated agricultural region：Yaqui Valley, Sonora, Mexico
surface water agricultural region groundwater flow
2009/5/18
Multi-objective optimization was used to calibrate a regional surface water-groundwater model of the Yaqui Valley, a 6800 km2 irrigated agricultural region located along the Sea of Cortez in Sonora, ...
Distributed hydrological modeling of total dissolved phosphorus transport in an agricultural landscape, part II：dissolved phosphorus transport
total dissolved phosphorus Soil Moisture Distribution and Routing Model
2009/5/13
Reducing non-point source phosphorus (P) loss to drinking water reservoirs is a main concern for New York City watershed planners, and modeling of P transport can assist in the evaluation of agricultu...
Distributed hydrological modelling of total dissolved phosphorus transport in an agricultural landscape, part I: distributed runoff generation
Soil Moisture Distribution and Routing distributed runoff generation
2009/5/13
Successful implementation of best management practices for reducing non-point source (NPS) pollution requires knowledge of the location of saturated areas that produce runoff. A physically-based, full...
Assessment of alternative land management practices using hydrological simulation and a decision support tool：Arborea agricultural region, Sardinia
land management practices hydrological simulation Arborea agricultural region
2009/5/13
Quantifying the impact of land use on water supply and quality is a primary focus of environmental management. In this work we apply a semidistributed hydrological model (SWAT) to predict the impact o...
Is there a link between agricultural land-use management and flooding?
land-use management flooding agricultural
2009/5/6
Over the past fifty years, significant changes in UK land use and management practices have occurred, driven by UK and EU agricultural policies. There is substantial evidence that modern land-use mana...
