Abstract:

The groundwater (GW) and surface water (SW) interaction (SW-GW) through the hyporheic zone is a significant component in sustainable water resource management. The complexities in SW-GW interactions increase from a local to a regional scale and are affected by variation in hydraulic, hydrologic, and hydrogeologic (3H) processes. Controlling factors and their upscaling of these processes to assess SW-GW interaction have not been addressed sufficiently in previous studies. Additionally, it is unclear what the effective factors are at different scales during the upscaling. Therefore, the present

Abstract:

Interactions between groundwater (GW) and surface water (SW) have been a focus of hydrologic research for some time. Seminal early work by Toth (1963) and later Winter (1999) had shown the existence of nested GW flow systems and stressed that surface water bodies are integral parts of these flow systems. Despite this early, integral perspective, a simpler perception of GW and SW as two distinct compartments, which interact via some often loosely defined transfer mechanisms, still prevails. This perception can be found in many hydrologic models, but can be misleading, as it implies the existenc

Abstract:

Interactions between groundwater and surface water (GW-SW interactions) play a crucial role in the hydrological cycle; thus, the quantification of GW-SW interactions is essential. In this study, a cumulative exchange fluxes method based on mass balance theory is proposed for a stream-aquifer system. This method determines the curve of cumulative fluxes through the water balance term, which can characterize GW-SW interactions, determine the amount of exchange fluxes, and reveal the dynamic process of interactions. This method is used in a reach of the Taizi River Basin, and the GW-SW interactio

Abstract:

Groundwater (GW) in the Mississippi Delta has some of the highest phosphorus (P) concentrations measured in the U.S. Chemical data collected from GW and surface water (SW) sites were compared to understand factors affecting P concentrations. Spatial instability in Delta GWs indicates that P sources vary. High P measurements in shallow wells near rivers, in shallow nested wells compared to deeper nested wells, and P fluctuations in wells over time suggest that the land surface may be a greater source of P in shallow groundwater than natural geological deposits.

Abstract:

Groundwater and surface water, though thought to be different entities in the past, are connected throughout the different landforms of the world. Despite being studied for quite some time, the interaction between groundwater and surface water (GW–SW) has received attention recently because of the heavy exploitation of both of these resources. This interaction is responsible for a phenomenon like contaminant transport, and understanding it helps to estimate the effects of climate change, land use on chemical behavior, and the nature of water. Hence, knowledge of GW–SW interactions is required

Groundwater-surface water (GW-SW) interaction lengthens hydraulic residence times, increases contact between solutes and biologically active surfaces, and often creates a gradient of redox conditions conducive to an array of biogeochemical processes. As such, the interaction of hydraulic patterns and biogeochemical activity is suspected to be an important determinant of elemental spiraling in streams. Hydrologic interactions may be particularly important in headwater streams, where the extent of the GW-SW mixing environment (i.e., hyporheic zone) is proportionately greater than in larger strea

Groundwater and surface water (hereafter: GW and SW) are typically identified as different compartments of the hydrological cycle and were traditionally often studied and managed separately. However, despite this separation, these respective fields of study are usually not considered to be different disciplines. They are often seen as different specialisations of hydrology with different focus, yet similar theory, concepts, methodol

Abstract:

Dealing with large watersheds sometimes becomes challenging, especially when simulating the surface water-groundwater (SW-GW) interaction within the floodplain. Using satellite data (such as land cover, topography, bathymetry, soil zones, imagery, etc.) can be an excellent way to characterize the surface and subsurface properties to handle large basins, especially those suffering drastic changes due to natural disasters. This study employs satellite data from 2016 and 2019 to develop integrated SW-GW models, aiming to assess the impacts of changes in basin characteristics on surface-subsurface

Investigation of GW-SW is crucial in hydrology and water resource management, employing diverse methodologies. This study integrates hydrogeological measurements and isotopic techniques to assess water sources, using δ2H and δ18O values. In the Thach Han River region of central Viet Nam, challenges like declining groundwater levels and salinization persist. During the dry season, groundwater recharge mainly comes from reservoir water for about 7 months. Base flow contributes 80-85% to streamflow in the rainy season, rising to 100% in the dry season, with an average travel time estimated at 120

In the arid inland basins of China, the long-term unregulated agricultural irrigation from surface water diversion and groundwater abstraction has caused the unsustainability of water resources and the degradation of ecosystems. This requires the integrated management of surface water (SW) and groundwater (GW) at basin scale to achieve scientific decisions which support sustainable water resource allocation in China.

Abstract. Secondary dryland salinity is a global land degradation issue. Drylands are often less developed, less well instrumented and less well understood, requiring us to adapt and impose understanding from different hydro-geomorphological settings that are better instrumented and understood. Conceptual models of secondary dryland salinity, from wet and more hydrologically connected landscapes imposed with adjustments for rainfall and streamflow, have led to the pervasive understanding that land clearing alters water balance in favour of increased infiltration and rising groundwater that bri

Abstract:

Interactions between groundwater (GW) and surface water (SW) have been a focus of hydrologic research for some time. Seminal early work by Toth (1963) and later Winter (1999) had shown the existence of nested GW flow systems and stressed that surface water bodies are integral parts of these flow systems. Despite this early, integral perspective, a simpler perception of GW and SW as two distinct compartments, which interact via some often loosely defined transfer mechanisms, still prevails. This perception can be found in many hydrologic models, but can be misleading, as it implies the existenc

Abstract:

Groundwater-surface water (GW-SW) interaction, as a key component in the cold region hydrologic cycle, is extremely sensitive to seasonal and climate change. Specifically, the dynamic change of snow cover and frozen soil bring additional challenges in observing and simulating hydrologic processes under GW-SW interactions in cold regions. Integrated hydrologic models are promising tools to simulate such complex processes and study the system behaviours as well as its responses to perturbations. The cold region integrated hydrologic models should be physically representative and fully considerin

This concept helps compensate for each individual model's shortcomings and incorporates the models' advantages. However, challenges arise from temporal scale disparities between SW and GW models.

Quantifying water and heat fluxes at the surface water (SW)–groundwater (GW) interface is crucial for ensuring sustainable water management and quality. However, direct field-based quantification remains challenging due to the dynamic nature of SW-GW interactions, which are influenced by poorly constrained boundary conditions and spatial hydrofacies distributions. Traditionally, these parameters are inferred through model calibration using conventional data, such as hydraulic heads and river discharge.

In this paper, we propose a novel methodology for multivariate assimilation of Sentinel‐based leaf area index (LAI) as well as in‐situ records of streamflow.
