Perspectives of Hydrologic Modeling in Agricultural Research

open access: yes, 2021
For decades agricultural research was done in the field or laboratories, but with the rise of computer science, hydrologic modeling became another essential tool for environmental impact studies. Many types of models can be used, each with its strengths and weaknesses in terms of accuracy, speed, and amount of input data needed.

Assessing the demand for hydrological drought insurance in irrigated agriculture

open access: yesAgricultural Water Management, 2022
Concerns about hydrological drought risk and irrigation water supply reliability have grown in recent years due to the increasing demand for water for irrigation and other uses, and the decline in water availability due to climate change. Hydrological drought insurance hedging against water supply gaps can be a key instrument for adapting irrigated ...

Modeling of hydrological processes in arid agricultural regions [PDF]

open access: yesFrontiers of Agricultural Science and Engineering, 2015
Understanding of hydrological processes, including consideration of interactions between vegetation growth and water transfer in the root zone, underpins efficient use of water resources in arid-zone agriculture. Water transfers take place in the soil-plant-atmosphere continuum, and include groundwater dynamics, unsaturated zone flow, evaporation ...

Experimental short-time wildfire simulation—Physicochemical changes of forest mucky topsoil

open access: yesFrontiers in Forests and Global Change, 2022
Today, fires constitute one of the most important factors that can affect soil properties, acting at a rapid pace and on a large scale. They often result from climate change.
