Nutrient and Contaminant Export Dynamics in a Larger-order Midwestern Watershed: Upper White River, Central Indiana, USA
export nitrogen nitrate phosphorus atrazine
2015/1/16
The transport of excess nutrients, sediment, and other contaminants to surface waters has been shown to cause a number of environmental and human health concerns. An understanding of the export pathwa...
Erosion Predictions by Empirical Models in a Mountainous Watershed in Nepal
Mountainous Watershed Nepal
2015/1/8
Soil erosion is a crucial problem in Nepal where more than 80% of the land area is mountainous. In this study, two commonly used empirical soil erosion models, Revised Universal Soil Loss Equation (RU...
Location of Fraction-Saturated Areas in Watershed Using Empirically Calculated Topographical Index
Shivalik region of India India
2015/1/8
In engineering practice, simple methods are important for predicting runoff from watersheds particularly for flood forecasting and water balance calculations. In the present study, it is illustrated t...
Understanding and managing water resource problems involves complex processes and interactions within the watershed surface and subsurface. The imposition of total maximum daily load (TMDL) regulation...
A Spatial Technique for Estimating Streambank Erosion Based On Watershed Characteristics
watershed modeling streambank erosion sediment transport
2015/1/4
A GIS-based technique was developed for estimating streambank erosion rates for more accurately predicting total sediment loads at the watershed scale without the use of detailed field data. This tech...
Using Bayesian networks to model watershed management decisions:an East Canyon Creek case study
Bayesian networks watershed management decisions East Canyon Creek
2009/12/4
An approach to developing and using Bayesian networks to model watershed management decisions is presented with a case study application to phosphorus management in the East Canyon watershed in Northe...
The stochastic approach to watershed modeling refers to the techniques
used to generate synthetic hydrologic data. These data may be used either
for input to a parametric watershed model or to provi...
The parametric approach to watershed modeling is shown to lie between
the stochastic and deterministic approaches. Essentially, the parametric
approach attempts to find functional relationships betw...
Physically-based, deterministic models, are considered in this paper.
Physically-based, in that the models have a theoretical structure based
primarily on the laws of conservation of mass, energy, o...
This paper summarizes the main points of a theoretical study of the general
watershed behaviour, on the basis of the known deterministic physics-based
approaches for overland flow, underground flow ...
Landsat Thematic Mapper (TM) Derived Reflectance from a Mountainous Watershed during the Snow Melt Season
Landsat Thematic Mapper Mountainous Watershed Snow Melt Season
2009/10/26
Landsat-5 Thematic Mapper (TM) reflectances recorded i May 1989 from a
mountainous catchment at Kvikne, Norway, are analyzed and compared with
simultaneously measured in situ albedo. The satellite-r...
