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.

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.

Design and realization of monitoring system for measuring air temperature and humidity, wind direction and speed

open access: yesJournal of Environmental Engineering and Landscape Management, 2006
An air humidity sensor based on the capacity principle and programmable digital air temperature sensors are designed in the work. The wind direction and wind speed sensor (anemometer) is based on the optoelectronic principle.

Developing a geomorphological instantaneous unit hydrograph (GIUH) using equivalent Horton-Strahler ratios for flash flood predictions in arid regions

open access: yesGeomatics, Natural Hazards & Risk, 2020
The Horton-Strahler ratios are important to describe the stream network and to identify the hydrologic response of a basin using the GIUH concept. These ratios are often sensitive to the selected threshold area for the extraction of the stream network ...

California's Central Valley Groundwater Wells Run Dry During Recent Drought

open access: yesEarth's Future, 2020
Declining water tables are causing wells to run dry in California, but the prevalence and spatial distribution of wells that have run dry are not known beyond anecdotal and voluntary reports. Here, we apply a new, simple, and measurement‐driven method to
