Points:  On-the-go soil sensors are able to map soil texture, organic matter, and pH, along with topography  A multi-sensor system effectively mapped a set of 10 fields across 6 states, delineating variability not detected by USDA soil surveys  A proprietary fuzzy logic system that classifies productivity zones was able to estimate productivity differences  Detailed quantitative soil maps a...

Abstract This study describes the results of groundwater table variation in Thanjavur District before and after monsoon seasons. Groundwater-level data acquired by field measurement elevation have been obtained from topographic survey. Groundwater is major source for different sectors this region, portion was used irrigation. The impacts geology, soil types, elevation, land-use changes were cri...

Reliable characterization of subsurface soil in urban areas is a major concern in geotechnical and geological engineering projects. In this regard, this research deals with development of a 3D geological engineering model on Mashhad City soil using Sequential Gaussian Simulation (SGS) approach. The intense variability of soil in the study area has sometimes caused serious problems in civil engi...

The aim of this study is to estimate runoff in Wadi Ba Al Arid watershed for a period of ten years 2009-2018 by  Soil Conservation Service  Curve Number (SCS-CN) method in combination with the GIS techniques using remote sensing data. The used data are the daily rainfall data from NASA Prediction of Worldwide Energy Resource (POWER), digital elevation data (DEM) from ALOS PALSAR RTC , satellite...
