Numerical modeling of aquaculture dissolved waste transport in a coastal embayment
Effluent pollution Dispersion Aquaculture Numerical modeling Plume dynamics Coastal engineering
2015/6/30
Marine aquaculture is expanding rapidly without reliable quantification of effluents. The present study focuses on understanding the transport of dissolved wastes from aquaculture pens in near-coastal...
Evaluation of qualitative attributes of forest ecosystems by means of numerical quantifiers
forest ecosystems forest biotopes quantification of qualitative attributes
2015/3/5
This paper presents a proposal of four variants of quantifiers for the numerical expression of qualitative attributes of forest ecosystems, for example site, naturalness, biodiversity, ecological stab...
Numerical Analysis of Ponded Infiltration Experiment under Different Experimental Conditions
infiltration single-ring infiltrometer saturated hydraulic conductivity

One of the most important properties, affecting the flow regime in the soil profile, is the topsoil
saturated hydraulic conductivity (Ks
).
Numerical Study of Macropore Impact on Ponded Infiltration in Clay Soils
ponded infiltration macropores and fractures preferential flow single-porosity system dual-permeability system HYDRUS-1D
2015/1/28
The single-porosity and dual-permeability models in HYDRUS-1D (Šimůnek et al. 1998, 2003) were used to simulate variably-saturated water movement in clay soils with and without macropores. N...
Diffusion models for the description of seedless grape drying using analytical and numerical solutions
Optimization Convective Boundary Condition Diffusion Model
2013/2/28
This article compares diffusion models used to describe seedless grape drying at low temperature. The models were analyzed, assuming the following characteristics of the drying process: boundary condi...
Numerical Modeling of Wheat Irrigation using Coupled HYDRUS and WOFOST Models
LAI, leaf area index NSE, Nash–Sutcliffe coefficient SCE, shuffled complex evolution WOFOST, World Food Studies
2013/9/2
To efficiently manage water resources in agriculture, the hydrologic model HYDRUS-1D and the crop growth model WOFOST were coupled to improve crop production prediction through accurate simulations of...
Simple Numerical Expression of Leaf Shape in Pears (Pyrus sp.)
Simple Numerical Expression Leaf Shape Pears
2009/7/13
A simple and numerical expression of leaf shape in pears was developed using a photocopy and eight characters (leaf blade length / width ratio, petiole length / leaf blade length ratio, the widest par...
Scheduling of irrigation and drainage using numerical methods
water balance in the soil crop atmosphere system drain pipe spacing irrigation predicting plant growth
2008/11/12
In this paper the HZAR and UGWTPN models are described. The HZAR programme is used for the description of water flow in the soil with plant water uptake and for the account of drain pipe spacing. The ...
