Fuzzy Logic and Geostatistical Techniques for Spatialization of Soil Texture in Region with Rough Terrains
(Elsevier B.V., 2011-01-01)
From the geotechnical standpoint, it is interesting to analyse the soil texture in regions with rough terrain due to its relation with the infiltration and runoff processes and, consequently, the effect on erosion processes. ...
Using geostatistical analysis to evaluate the presence of Rotylenchulus reniformis in cotton crops in Brazil: Economic implications
(2002-09-01)
In recent years, the productivity of cotton in Brazil has been progressively decreasing, often the result of the reniform nematode Rotylenchulus reniformis. This species can reduce crop productivity by up to 40%. Nematodes ...
Communicating uncertainty about groundwater scenarios using stochastic simulation of water table depths time series
(2012-01-01)
Time series modeling provides an empirical stochastic method to model monitoring data from observation wells, without the complexity of physical mechanistic models. In the same direction, geostatiscal methods are used to ...
Diagnosis of a compacted area for mining through the mechanical resistance to the penetration using geostatistical methods in the Amazon Forest
(2004-12-01)
The mining process promotes land modification and complete landscape alteration. Those alterations in the surface are shown more obviously in the aesthetical aspect as the visual elements of form, texture, climbs, complexity ...
Lógica fuzzy na avaliação da fertilidade do solo e produtividade do café conilon
(Univ Federal Ceara, Dept Geol, 2010-01-01)
The objective of this study was to analyze, using the geoestatistic and a system of classification fuzzy, the fertility of an experimental area with base in chemical attributes of the soil and its relationship with the ...
Surface temperature estimated with Landsat 8 images and geostatistical tools in the northwestern Sao Paulo state
(Spie-int Soc Optical Engineering, 2017-01-01)
In the northwestern side of Sao Paulo state, irrigated crops are replacing natural vegetation, bringing importance for the development and applications of tools to quantify the energy and water balances. Remote sensing ...
Submerged macrophytes height estimation by echosounder data sample
(2012-12-01)
Traditional methods of submerged aquatic vegetation (SAV) survey last long and then, they are high cost. Optical remote sensing is an alternative, but it has some limitations in the aquatic environment. The use of echosounder ...
