Intertidal sediment grain size is one of the environmental parameters that can explain the interaction between the marine and terrestrial environments. Geostatistics has been widely used to model spatial distribution of many geological objects. However, there have been a few researches concerning application to grain size distribution. The aim of this study is to clarify surface sediment distri...

The spatial pattern of soil moisture varies at different scales due to evapo-transpiration and precipitation which are transformed by topography, soil texture, and vegetation. The mapping of soil moisture by remote sensing has several advantages over conventional field measurement techniques especially in the case of heterogeneous landscapes. However, validation of low resolution satellite soil...

Air pollution is a serious matter that must be addressed promptly and quickly. One of the most dangerous pollutants in air PM2.5. This pollutant particulates dust measuring 2.5 micrometers. PM2.5 can cause environmental health problems such as acute respiratory infections, lung cancer, cardiovascular premature death. occurs big cities capital city Indonesia, DKI Jakarta, which with highest leve...

18 Tea fields emit large amounts of nitrous oxide (N2O) to the atmosphere. Obtaining accurate 19 estimations of N2O emissions from tea-planted soils is challenging due to strong spatial 20 variability. We examined the spatial variability of N2O emissions from a red-soil tea field in 21 Hunan province, China, on 22 April 2012 (in a wet season) using 147 static mini chambers 22 approximately regu...

Iranshahr Basin is located in the Sistan and Baluchistan province, subject to severe drought excessive groundwater utilization. Over-reliance on resources this area has led aquifer drawdowns socio-economic problems. The present study aimed identify appropriate sites for Artificial Recharge Groundwater (ARG) a single platform by applying GIS fuzzy logic spatial modeling. Three stages were perfor...

False smut disease (FSD) of rice incited by Ustilaginoidea virens is an emerging threat to paddy cultivation worldwide. We investigated the spatial distribution FSD in different ecosystems South Indian states, viz., Andhra Pradesh, Karnataka, Tamil Nadu, and Telangana, considering exploratory data from 111 sampling sites. Point pattern surface interpolation analyses were carried out identify pa...

Four spatial estimation techniques available in commercial computational packages are evaluated and compared, namely: regularized splines interpolation, tension splines interpolation, inverse distance weighted interpolation, and ordinary Kriging estimation, in order to establish the best representation for the shallow stratigraphic configuration in the city of Aguascalientes, in Central Mexico....

Soil quality assessment is the first step towards precision farming and agricultural management. In present study, a multivariate analysis geographical information system (GIS) were used to assess map soil index (SQI) in El-Fayoum depression Western Desert of Egypt. For this purpose, total 36 geo-referenced representative samples (0–0.6 m) collected analyzed according standardized protocols. Pr...

Spatial information surveyed by photogrammetry, airborne LiDAR and Mobile Measurement System (MMS) above ground level can be analyzed by scientists using standard geostatistical methodologies such as ordinary Kriging and sequential Gaussian simulation to interpolate heterogeneities of profiles from sparse sample data. Proven effective by researchers, the Kriging algorithm model is used by comme...
