2020年2月，水文地质学期刊《Journal of Hydrology》刊发了中国地质大学工程学院周佳庆副教授团队题为《Effect of fluid slippage on eddy growth and non-Darcian flow in rock fractures》的学术成果。该文采用高精度数值模拟方法和水流涡旋区自动检测技术，研究了岩石裂隙壁面流体滑移对裂隙岩体宏细观渗流特性的影响...
A Method for Extracting Stream Channel Flow Paths from LiDAR Point Cloud Data
Streams Channels Delineation
2015/1/9
Traditional methods of delineating stream channel networks use gridded raster elevation data. Direct use of LiDAR point clouds, without first creating a raster or grid, could improve efficiency and ac...
Groundwater Flow Model and Particle Track Analysis for Selecting Water Quality Monitoring Well Sites, and Soil Sampling Profiles
modelling pollution studies Imo River basin
2015/1/8
Researchers often use only surface drainage (imperical method) as a tradition to locate sites for installation of water quality monitoring wells, and soil sampling profile for pollution studies in urb...
Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
overland flow erosion catchment scale
2015/1/4
Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...
NUMERICAL SOLUTION FOR TRANSIENT WELL FLOW IN AN UNCONFINED-CONFINED AQUIFER SYSTEM
TRANSIENT WELL FLOW groundwater aquifer system
2009/10/12
It is quite common that the extraction of groundwater is from more than one aquifer system, where a combination of unconfined and confined aquifers is found. The problem lies in how to find the discha...
DELINEATING THE SUBSURFACE：USING SURFACE GEOPHYSICS TO IDENTIFY GROUNDWATER FLOW PATHS IN A CARBONATE AQUIFER
GROUNDWATER FLOW PATHS CARBONATE AQUIFER
2009/10/12
This study examines stream loss in a small tributary of the Youghiogheny River known as Hoyes Run in Garrett County, Maryland. The stream bounds the pit of the Deep Creek limestone quarry, operated by...
Use of soil moisture dynamics and patterns at different spatio-temporal scales for the investigation of subsurface flow processes
soil moisture dynamics subsurface flow processes
2009/7/22
Spatial patterns as well as temporal dynamics of soil moisture have a major influence on runoff generation. The investigation of these dynamics and patterns can thus yield valuable information on hydr...
Connecting ecohydrology and hydropedology in desert shrubs：stemflow as a source of preferential flow in soils
ecohydrology soils hydropedology water flow
2009/7/22
Ecohydrology and hydropedology are two emerging fields that are interconnected. In this study, we demonstrate stemflow hydrology and preferential water flow along roots in two desert shrubs (H. scopa...
Dye staining and excavation of a lateral preferential flow network
flow network solute transport flow paths
2009/7/22
Preferential flow paths have been found to be important for runoff generation, solute transport, and slope stability in many areas around the world. Although many studies have identified the particula...
Depth distribution of preferential flow patterns in a sandy loam soil as affected by tillage
sandy loam soil tillage flow patterns
2009/6/8
Dye-tracer studies using the anionic dye Brilliant Blue FCF were conducted on a structured sandy loam soil (Typic Agrudalf). 25 mm of dye solution was applied to the surface of 11 1.6 x 1.6 m field p...
The effects of clear-felling established forestry on stream-flow losses from the Hore sub-catchment
Hore sub-catchment clear-felling stream-flow losses
2009/6/8
The effects on streamflow of clear-felling a substantial part of the established forestry within the Hore sub-catchment at Plynlimon were estimated by a regression comparison of pre-and post-felling r...
