Agricultural Irrigation Effects on Hydrological Processes in the United States Northern High Plains Aquifer Simulated by the Coupled SWAT-MODFLOW System

open access: yesWater, 2022
Groundwater use for irrigation has a major influence on agricultural productivity and local water resources. This study evaluated the groundwater irrigation schemes, SWAT auto-irrigation scheduling based on plant water stress (Auto-Irr), and prescribed ...

A high-resolution transient 3-dimensional hydrological model of an extensive undisturbed bog complex in West Siberia [PDF]

open access: yesMires and Peat, 2020
Data on the distributed dynamics of water table elevation (WTE) and on the variation of water discharge are needed for calculation of the carbon balances of entire mire complexes.

Scientific basis for safely shutting in the Macondo Well after the April 20, 2010 Deepwater Horizon blowout [PDF]

open access: yes, 2012
As part of the government response to the Deepwater Horizon blowout, a Well Integrity Team evaluated the geologic hazards of shutting in the Macondo Well at the seafloor and determined the conditions under which it could safely be undertaken.

Revisiting MODFLOW's Capability to Model Flow Through Sedimentary Structures

open access: yesGround Water, 2022
Sedimentary structures have unique geometries and anisotropic hydraulic conductivity, both of which control groundwater flow. Traditional finite‐difference simulators (e.g., MODFLOW) have not been able to correctly represent irregular, dipping and ...

Numerical simulation of radionuclides migration in the far field of a geological repository [PDF]

open access: yes, 2015
Safety conditions associated with geological repositories must be guaranteed also in the case of radionuclides migrating from the near field to the far field of a geological repository and to the external environment.

A standardised method for measuring in situ denitrification in shallow aquifers: numerical validation and measurements in riparian wetlands [PDF]

open access: yes, 2003
A tracer test to examine in situ denitrification in shallow groundwater by a piezometer with a packer system used bromide as a tracer of dilution and acetylene (10%) to block the denitrification process at the nitrous oxide stage.

Projection of the Relationship between Climate Change Groundwater Resources Based on the MODFLOW Model [PDF]

open access: yesمدیریت بیابان
Climate change, a phenomenon that has been occurring since ancient times, has accelerated in recent years. This study investigates the impact of climate change on groundwater resources using the MODFLOW model. To achieve this, the water balance was first

A Conceptualized Groundwater Flow Model Development for Integration with Surface Hydrology Model

open access: yes, 2017
A groundwater system model was developed and calibrated in the study area of Lehman Creek watershed, eastern Nevada. The model development aims for integrating the surface hydrologic model - precipitation runoff modeling system (PRMS) model - with the ...
