Quantifying the effect of land use and land cover changes on green water and blue water in northern part of China
(Copernicus Publications on behalf of the European Geosciences Union, 2009-06-12)
Changes in land use and land cover (LULC) have been occurring at an accelerated pace in northern parts of China. These changes are significantly impacting the hydrology of these parts, such as Laohahe Catchment. The ...
A kinematic model for surface irrigation: An extension
(American Geophysical Union, 1982-06)
The kinematic model for surface irrigation, reported previously by Sherman and Singh (1978), is extended. Depending upon the duration of irrigation and time variability of infiltration, three cases are distinguished. ...
Solute transport under steady and transient conditions in biodegraded municipal solid waste
(American Geophysical Union, 1999-08)
The transport of a conservative tracer (lithium) in a large (3.5 m3) undisturbed municipal solid waste sample has been investigated under steady and fully transient conditions using a simple model. The model comprises a ...
A kinematic model for surface irrigation: Verification by experimental data
(American Geophysical Union, 1983-12)
A kinematic model for surface irrigation is verified by experimental data obtained for 31 borders. These borders are of varied characteristics. Calculated values of advance times, water surface profiles when water reaches ...
Kinematic wave model for water movement in municipal solid waste
(American Geophysical Union, 1998-11)
The movement of water in a large (3.5 m3) undisturbed sample of 22-year-old municipal solid waste has been modeled using a kinematic wave approximation for unsaturated infiltration and internal drainage. The model employs ...
A stochastic model for sediment yield using the Principle of Maximum Entropy
(American Geophysical Union, 1987-05)
The principle of maximum entropy was applied to derive a stochastic model for sediment yield from
upland watersheds. By maximizing the conditional entropy subject to certain constraints, a probability
distribution of ...
Kinematic wave model of bed profiles in alluvial channels
(American Geophysical Union, 2006-06-21)
A mathematical model, based on the kinematic wave (KW) theory, is developed for describing the evolution and movement of bed profiles in alluvial channels. The model employs a functional relation between sediment transport ...
Kinematic wave model for transient bed profiles in alluvial channels under nonequilibrium conditions
(American Geophysical Union, 2007-12-27)
Transient bed profiles in alluvial channels are generally modeled using diffusion (or dynamic) waves and assuming equilibrium between detachment and deposition rates. Equilibrium sediment transport can be considerably ...
A distributed converging overland flow model: 2. Effect of infiltration
(American Geophysical Union, 1976-10)
The overland flow on an infiltrating converging surface is studied. Mathematical solutions are developed
to study the effect of infiltration on nonlinear overland flow dynamics. To develop mathematical
solutions, ...
A fractional dispersion model for overland solute transport
(American Geophysical Union, 2006-03-18)
Using the kinematic-wave overland flow equation and a fractional dispersion-advection equation, a process-oriented, physically-based model is developed for overland solute transport. Two scenarios, one consisting of downslope ...
