Hydrometeorological factors determining the development of water table cave patterns in high alpine zones. The Ordesa and Monte Perdido National Park, NE Spain

International Journal of Speleology, 2020
This study is focussed on the geomorphological characterization and the processes driving the evolution of the highest karst system in Western Europe, which is located in the Ordesa and Monte Perdido National Park (PNOMP), in the central-southern ...

A Saint-Venant Model for Overland Flows with Precipitation and Recharge

Mathematical and Computational Applications, 2020
We propose a one-dimensional Saint-Venant (open-channel) model for overland flows, including a water input–output source term modeling recharge via rainfall and infiltration (or exfiltration).

Regional assessment of groundwater recharge in the lower Mekong Basin [PDF]

, 2017
Groundwater recharge remains almost totally unknown across the Mekong River Basin, hindering the evaluation of groundwater potential for irrigation. A regional regression model was developed to map groundwater recharge across the Lower Mekong Basin where

Water budget study for groundwater recharge in Indus River Basin, Punjab (Pakistan)

H2Open Journal, 2023
Assessing groundwater recharge is crucial for managing and governing water resources in any region. Indus River Basin (IRB) is an area that relies heavily on canal and groundwater irrigation.

Microbial community changes induced by Managed Aquifer Recharge activities: linking hydrogeological and biological processes [PDF]

, 2019
Managed Aquifer Recharge (MAR) is a technique used worldwide to increase the availability of water resources. We study how MAR modifies microbial ecosystems and its implications for enhancing biodegradation processes to eventually improve groundwater ...

Assessing the impacts of different crop rotations on groundwater level using MODFLOW in a dry, Barind area of Bangladesh

Water Policy, 2023
The lowering of the groundwater table caused by increased groundwater use in the dry, Barind region has prompted sustainability concerns. In this study, water-table (WT) scenarios were simulated by the MODFLOW model under different crop rotations in ...

Performance of three reanalyses in simulating the water table elevation in different shallow unconfined aquifers in Central Italy

Meteorological Applications, 2023
Water table elevation is a key feature for identifying the groundwater behaviour. Accordingly, appropriate measurements—in terms of both frequency and spatial distribution—play a crucial role for capturing the aquifer response to recharge and withdrawals.

Determination of water balance equation components in irrigated agricultural watersheds using SWAT and MODFLOW models : A case study of Samalqan plain in Iran

Journal of Groundwater Science and Engineering, 2022
Increasing water demands, especially in arid and semi-arid regions, continuously exacerbate groundwater as the only reliable water resources in these regions.

Physical Structure of the Epikarst

Acta Carsologica, 2013
Epikarst is a weathered zone of enhanced porosity on or near the surface or at the soil/bedrock contact of many karst landscapes. The epikarst is essentially the upper boundary of a karst system but is also a reaction chamber where many organics ...
