Optimizing regional crop water consumption is considered to be a significant approach for increasing yields and reducing water consumption. This paper proposes a single-objective linear programming model which couples the distributed water consumption model with crop suitability. The impacts of meteorological, topographic, and soil factors were tak...
Flowpaths are significantly affected by land use change and engineered elements across urban catchments. Conventional GIS-based tools for extracting drainage networks were not developed for urban terrains. This work presents Geo-PUMMA, a GIS toolbox to generate vectorial meshes for terrain representation in distributed hydrological modeling, and to...

Leptin receptors (ObRs) in the forebrain and hindbrain have been independently recognized as important mediators of leptin responses. We recently used low-dose leptin infusions to show that chronic activation of both hypothalamic and hindbrain ObRs is required to reduce body fat. The objective of the present study was to identify the brain nuclei t...
Watershed has many kinds of sources that pollute the receiving waters. Recently, although the pollutant load of point sources is being reducedby the construction of sewer system and water treatment plans, reduction of pollutant runoff from non-point source is insufficient. Thus, it is needed to establish the effective reduction methods for the furt...

Global solar radiation (GSR) is the most direct source and form of global energy, and calculation of its quantity is highly complex due to influences of local topography and terrain inter-shielding. Digital elevation model (DEM) data as a representation of the complex terrain and multiplicity condition produces a series of topographic factors (e.g....
This study organized previous discussions on renewable energy from a viewpoint of the contributions to local economies. In most previous works, energy business that depends on nuclear energy was considered to have a centralized structure. Meanwhile, renewable energy was considered to be geographically-distributed and have potentials to contribute t...
In recent years, the grasp of pollutants loads from watershed is needed for water quality improvement of water quality in receiving water area. The main purpose of this study is the estimation of pollutant runoff from watersheds in rain condition. In this study, the distributed type model on rainfall runoff and pollutants runoff was developed and a...
The principal challenge in the parameterization of storm flow models for agricultural catchments with an artificial drainage network and fields with different degrees of tillage lies in the parsimonious definition of distributed model parameters in a way that reduces the number of calibration parameters to a justifiable minimum. This paper presents...
Predicting the impact of land use changes on the hydrological response is crucial for water resource management. In the particular case of small catchments (1-10 km2), distributed models could provide useful answers regarding the effects of cultivation practices and man-made works on water fluxes. However, the impacts of specific land use spatial a...

Asymptotic and numerical analysis of relaxation self-oscillations in a three-dimensional system of Volterra ordinary differential equations that models the well-known Belousov reaction is carried out. A numerical study of the corresponding distributed model-the parabolic system obtained from the original system of ordinary differential equations wi...
