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 ......
