Gridded precipitation data with a high spatiotemporal resolution are of great importance for studies in hydrology, meteorology, and agronomy. Observational from meteorological stations cannot accurately reflect the distribution variations over large area. Meanwhile, radar-derived restricted by low accuracy areas complex terrain satellite-based spatial resolution. Therefore, hourly models were e...

groundwater resources are the most important sources of water consumption (agriculture, industry and drinking water) in arid and semi-arid regions. the management of these water resources is more expensive and difficult than surface waters; therefore more complicated and economic methods are needed for determination of their quality and quantity. in this study geostatistical methods of kringing...

population growth rating, high food demand, and land resource challenges have led to more serious studies of production factors especially the scarce water and soil resources. one of the most basic data items in land resources is the soil map. therefore, in the process of the present research for preparing soil maps of some soil quality indices at the faculty of agriculture experimental field (...

This study presents the map of external effective annual dose rate (1:200,000 scale) due to terrestrial and cosmic radiation. The is assessed via gamma ray spectroscopy combining radiometric data from airborne surveys laboratory measurements. geostatistical method Collocated CoKriging used for spatial interpolation sparse data, adopting a high-resolution geological as ancillary information. obt...

Abstract Accurate pore pressure models in wells are essential for ensuring the lowest cost and operational safety during exploration/development projects. This modeling requires integration of several sources information such as well data, formation tests, geophysical logs, mud weight, geological models, seismic geothermal sedimentation rate modeling. An empirical relationship between overpress...

The aim of this work was to elaborate a new methodology that can allow for the identification topsoil homogeneous area (tSHA) distribution along land parcels, supporting farmers in keeping low-cost, sustainable, and light logistic management precision agriculture (PA) practices. This paper shows assessment tSHA variability over two production units (PUs), considering radiometric response (optic...

Precipitation data provide a crucial input for examining hydrological issues, including watershed management and mitigation of the effects floods, drought, landslides. However, they are collected frequently from scarce often insufficient network ground-based rain-gauge stations to generate continuous precipitation maps. Recently, maps derived satellite have not been sufficiently linked rain gau...
