Physical Structure of the Epikarst

open access: yesActa 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 ...

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

open access: yes, 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

Recharge Response Functions [PDF]

open access: yesHydrology and Earth System Sciences, 1997
Abstract. This paper explores the establishment of transfer functions for describing the annual oscillation of unconfined aquifer water levels in response to effective precipitation. A simple saturated zone representation is developed to accompany the unsaturated zone mechanism. Practical examples are drawn from a sample of sites from the chalk and the

Mountain‐Block Recharge: A Review of Current Understanding

open access: yesWater Resources Research, 2019
Mountain‐block recharge (MBR) is the subsurface inflow of groundwater to lowland aquifers from adjacent mountains. MBR can be a major component of recharge but remains difficult to characterize and quantify due to limited hydrogeologic, climatic, and ...

Modeling Surface Water–Groundwater Interactions: Evidence from Borkena Catchment, Awash River Basin, Ethiopia

open access: yesHydrology, 2023
The availability of sufficient water resources is critical for sustainable social and economic development globally. However, recurrent drought has been a precursor to inadequate water supply in the case of Borkena Catchment, Awash River Basin, Ethiopia.

Karst and groundwater in northeastern Coahuila: An Edwards Aquifer mirror [PDF]

open access: yes, 2009
The northeastern corner of the Mexican state of Coahuila contains some of the most extensive limestone outcrops in the country, yet the karst and groundwater have seen relatively little investigation.

The Importance of Interflow to Groundwater Recharge in a Snowmelt‐Dominated Headwater Basin

open access: yesGeophysical Research Letters, 2019
Understanding the sensitivity of groundwater generation to climate in a mountain system is complicated by the tight coupling of snow dynamics to vegetation and topography. To address these feedbacks, we combine light detection and ranging (LiDAR)‐derived

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

open access: yesJournal 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.

Analysis of Groundwater Balance of Samalqan Plain Aquifer Using SWAT and MODFLOW Models

open access: yesعلوم آب و خاک, 2021
Reducing surface water resources and successive droughts and consequently excessive use of groundwater resources, especially for agricultural purposes, have caused irreparable damage to the natural resources of the country.
