Pedotransfer functions for estimating the van Genuchten model parameters in the Cerrado biome

Revista Brasileira de Engenharia Agrícola e Ambiental, 2023
ABSTRACT The Cerrado biome has presented challenges in reconciling its agricultural expansion with water availability. In this sense, water resources planning and management are fundamental for the economic, social, and environmental development of the Cerrado biome, which has been hampered by the lack of data, especially those referring to irrigation ...

Biological Salt‐Pump Effect: Long‐Term Stand Development of Haloxylon ammodendron and Its Role in Reshaping Soil Hydrothermal and Salinity Regimes

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation in the desert–oasis ecotone induces soil desiccation and secondary salinization. However, the seasonal dynamics of soil water–heat–salt interactions across plantations of different stand ages in arid regions remain unclear. Here, we investigated the seasonal patterns and coupled relationships of soil water–heat–salt dynamics in ...

Spatial Variability of Soil Parameters of the van Genuchten Model at a Regional Scale [PDF]

CLEAN – Soil, Air, Water, 2014
Spatial heterogeneity of soil water retention curves (SWRC) plays an important role in modelling the movement of water and solutes in soils. To characterize the spatial variability of SWRC parameters fitted by the van Genuchten (VG) equation, and then identify factors that closely correlated with the VG parameters, we collected undisturbed and ...

Innovations in polysaccharide‐based hydrogels in sustainable agriculture

Polymer International, EarlyView.
Polysaccharide‐based hydrogels are promising in sustainable agriculture, as these natural polymers have the ability to absorb water and nutrients and release them gradually in the soil, in addition to ensuring biodegradability and lower cost. However, some challenges still need to be overcome.

Quantification of flash flood peaks using computer simulation for potential hill torrents of Pakistan: A modeling study

River, EarlyView.
Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

Ecography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Determinação da condutividade hidráulica e da sorvidade de um solo com infiltrômetro a disco Determination of hydraulic conductivity and sorptivity of soil using a disk infiltrometer

Revista Brasileira de Engenharia Agrícola e Ambiental, 2001
Determinou-se a condutividade hidráulica e a sorvidade, a partir de dados de infiltração acumulada, utilizando-se um infiltrômetro a disco, em duas camadas de um Neossolo Flúvico (uma superficial, 15 - 25 cm de profundidade, argilosa, e outra 50 - 70 cm ...
