Experimental Study on Prevention of Coal and Gas Outburst by Hydraulic Fracturing in High Gas Coal Mine in Yangquan Mining Area

Energy Science &Engineering, EarlyView.
ABSTRACT To investigate the hydraulic fracturing mechanism of high‐fluid wells in the Yangquan mining area, coal seams from the Xinyuan and Xinjing mines were selected as research subjects. Experiments were conducted using the TCQT‐III low‐permeability coalbed gas‐phase displacement and production enhancement apparatus, along with the FINESORB‐3120 ...

Assessing Groundwater Potential in the Ziway Lake Watershed Using Geographical Information System, Analytic Hierarchy Process, and Drinking Water Quality Index

Global Challenges, EarlyView.
This study identifies groundwater potential zones in Ethiopia’s Ziway Lake watershed using GIS and the SWAT model. Over half the area shows moderate to very high potential. Nearly 40% of high‐potential zones also have good to excellent water quality. The results offer a practical tool for sustainable groundwater management, with potential application ...

Uncertain multi‐objective programming approach for planning supplementary irrigation areas in rainfed agricultural regions

Irrigation and Drainage, EarlyView.
Abstract Rainfed agriculture is crucial for ensuring global food and water security, and supplementary irrigation is an effective means of improving the economic benefits in rainfed agricultural regions. This study proposes a novel uncertain optimization approach to optimize supplementary irrigation areas in rainfed agricultural regions.

Drainage basins evolution during the Neogene-Quaternary. Ebro Basin eastern margin [PDF]

, 2016
The monocline layout of the sedimentary pile of the Ebro Basin in its Eastern margin determines the generation and emptying of the adjacent erosive basins. It controls the drainage changes in the original sedimentary basin. A model of emptying erosive

Modelling the Spatio‐Temporal Effects of Water Level Control in an Agricultural Collector Ditch Network

Irrigation and Drainage, EarlyView.
ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...

Quantitative evaluation of drainage attributes to infer hydrologic and morphological characteristics of upper Beas Basin, Himachal Pradesh: A GIS-based approach

Geology, Ecology, and Landscapes, 2021
Drainage morphometric analysis is a quantitative indexing of linear, areal, and relief attributes of a watershed, which is an essential prerequisite to understand the ongoing geomorphological, geological, and tectonic processes in a watershed that ...

Effects of drainage ditches and stone bunds on topographical thresholds for gully head development in North Ethiopia [PDF]

, 2015
Gully erosion is an extreme process of land degradation operating in different regions of the world. A common way to quantify the susceptibility of land to gully incision is the use of topographical thresholds for different land use types.

Long‐Term Effects of Land Use and Cover Change and Dam Rupture on Ichthyofauna in a Neotropical Stream

International Review of Hydrobiology, EarlyView.
ABSTRACT This study evaluates land use and land cover (LULC) changes and their impacts on the fish community of a neotropical stream in the Sorocaba River basin, Brazil, from 2006 to 2023. The watershed experienced landscape changes over time, categorized into four periods: rural interventions, urban interventions, restorative interventions, and post ...

Landscape Change and Threats to Conservation of River Dolphin Inia araguaiaensis (Cetacea: Iniidae) in the Brazilian Savanna

International Review of Hydrobiology, EarlyView.
ABSTRACT River dolphins are the least studied and most threatened cetaceans. Anthropogenic activities, including habitat fragmentation, pollution, and declining fish stocks, pose significant challenges to their survival. This study evaluated the effects of landscape changes resulting from human activity on the encounter rates of the putative species of
