Analysis of hydrological alteration and environmental flow in Sone river basin
Acta Geophysica - Tập 71 - Trang 949-960 - 2022
Environmental flow is an important indicator of river health as it maintains the
natural flow pattern of riverine ecosystem. Although numerous researches for
analyzing the hydrological alterations are there, still insightful investigation
of site specific knowledge should be required for riverine ecosystem protection.
In this study, the objective is to analyze the hydrological status of the Sone
r...
Climate-driven changes to streamflow patterns in a groundwater-dominated catchment
Acta Geophysica - Tập 65 Số 4 - Trang 789-798 - 2017
Peak ground acceleration prediction by fuzzy logic modeling for Iranian plateau
Acta Geophysica - Tập 68 - Trang 75-89 - 2019
In this study, fuzzy logic modeling is applied to a complex and nonlinear set of
data to predict both horizontal and vertical peak ground accelerations in
Iranian plateau. The data used for the model include an up-to-date seismic
catalogue from earthquakes in Iran for prediction of both horizontal and
vertical acceleration of a probable earthquake. Fuzzy logic toolbox on MATLAB
program was used fo...
Group method of data handling to forecast the daily water flow at the Cahora Bassa Dam
Acta Geophysica - Tập 70 - Trang 1871-1883 - 2022
The Zambezi watershed is essential for water supply, irrigation, fishing
activities, and river transport of the populations of Southern Africa. The
importance and variability of these water resources make it necessary to develop
studies that may help understand and manage them. Despite this need, water
resources studies for this region are still scarce. Therefore, the present work
aims to present ...
Ionospheric anomalies related to the Mw 6.5 Samar, Philippines earthquake
Acta Geophysica - Tập 71 - Trang 601-611 - 2022
Models belonging to the ionosphere that is directly affected by factors such as
solar activity, geomagnetic storm, earthquake, seasonal changes, and
geographical location need to be considered altogether. In this sense, the cause
of the ionospheric anomalies should be meticulously distinguished from each
other. Ionospheric anomalies that occur before or (and) after an earthquake have
a serious pla...
Relative amplitude preservation in high-resolution shallow reflection seismic: a case study from Fore-Sudetic Monocline, Poland
Acta Geophysica - - 2019
The acquisition parameters and methodology of seismic data processing for
high-resolution seismic imaging viewed through relative amplitude preservation
are presented. An example of the obtaining of high-quality, shallow seismic data
with a variable end-on spread is shown. The source used for the project is an
accelerated weight drop. The study area lies within the mine waste disposal
area, near R...
Photogrammetric reconstruction of changes in vertical river position using archival aerial photos: case study of the Czarny Dunajec River, Polish Carpathians
Acta Geophysica - Tập 67 - Trang 1205-1221 - 2019
Rivers of the Polish Carpathians incised deeply during the twentieth century,
but detailed information about the timing and amount of incision of their
channels exists only for water-gauge cross sections. Applicability of
photogrammetric extraction of digital elevation models (DEMs) from archival
aerial photos for reconstructing changes in vertical river position was verified
in the study of a 3-k...
Use of Entropy in the Assessment of Uncertainty of River Runoff Regime in Poland
Acta Geophysica - Tập 64 Số 5 - Trang 1825-1839 - 2016
Unbiased total electron content (UTEC), their fluctuations, and correlation with seismic activity over Japan
Acta Geophysica - Tập 66 - Trang 51-70 - 2017
Earthquakes are among the most dangerous events that occur on earth and many
scientists have been investigating the underlying processes that take place
before earthquakes occur. These investigations are fueling efforts towards
developing both single and multiple parameter earthquake forecasting methods
based on earthquake precursors. One potential earthquake precursor parameter
that has received ...
