“…Banks et al (2011) evaluated the importance of vegetation on the nature of the connection between SW-GW and conceptualized the impact of a clogging layer (a low hydraulic permeability layer at the bed), evapotranspiration, and the slope of the catchment using the 2-D HydroGeoSphere model, assuming both homogeneous and isotropic conditions. Batlle-Aguilar et al (2015) calibrated and validated a 2D model for an ephemeral stream assuming isotropic and no flow conditions at the soil surface. Similarly, Xian et al (2017) analyzed the importance of lateral flow on SW-GW using conceptual transient simulations for the 2D and 3D systems in the context of heterogeneous streambeds.…”

A variably-saturated finite element model HYDRUS-2D was used to simulate the spatiotemporal dynamics of stream-aquifer exchange for a perennial stream flowing through an undulating catchment and underlain by heterogeneous geology. The model was first calibrated and validated using piezometric heads measured near the stream. The model was then used a) to quantify the long-term dynamics of exchange at stream-aquifer interface and the water balance in the domain, and b) to evaluate the impact of anisotropy of geological materials, thickness (w) and hydraulic conductivity (K s ) of the low permeability layer at the streambed, and water table fluctuations on the extent of exchange. Simulated pressure heads in the domain revealed that seasonal groundwater fluctuations were more pronounced near the stream. Daily discharge to the stream varied from 0.05 to 0.3 mm/day, annual discharge ranged from 59 to 74 mm, and the overall water balance showed a discharge (−54 mm) from the domain during 2000-2012. A fivefold increase in K s of the low permeability layer enhanced discharge to the stream by 14% (10 mm/year) whereas an increase in the thickness of the layer by 1 m had a low impact (2.4 mm/ year). A 2-m drawdown of the water table transformed a connected and gaining system into a

Seepage problems exist in water conservancy projects, groundwater research, and geological research, and hydraulic conductivity is an important factor that affects the seepage field. This study investigates the heterogeneity of hydraulic conductivity. Kriging methods are used to simulate the spatial distribution of hydraulic conductivity, and the application of resistivity and grain size is used to obtain hydraulic conductivity. The results agree with the experimental pumping test results, which prove that the distribution of hydraulic conductivity can be obtained economically and efficiently and in a complex and wide area.

“…In recent years, the fully‐integrated surface and subsurface flow and transport model, HydroGeoSphere (HGS) (Aquanty ), has been applied in several studies to investigate surface water‐groundwater interaction along river channels. For example, Batlle‐Aguilar et al () used HGS to simulate the infiltration of surface water from a disconnected stream to groundwater for a river transect in South Australia; Alaghmand et al () used HGS to investigate the potential use of artificial flooding as a short‐term saline groundwater management technique along floodplains in arid and semi‐arid environments; Xie et al () simulated the interaction of saline groundwater with surface water during stream events within an idealized river reach; and Schilling et al () used HGS to investigate the impact of river bed clogging on surface water‐groundwater interaction and the redistribution of water beneath disconnected streams.…”

Natural Stimuli Calibration with Fining Direction Regularization in an Integrated Hydrologic Model

et al. 2018

The interaction between surface water and groundwater during flood events is a complex process that has traditionally been described using simplified analytical solutions, or abstracted numerical models. To make the problem tractable, it is common to idealize the flood event, simplify river channel geometry, and ignore bank soil heterogeneity, often resulting in a model that only loosely represents the site, thus limiting its applicability to any specific river cross‐section. In this study, we calibrate a site‐specific fully‐integrated surface and subsurface HydroGeoSphere model using flood events for a cross‐section along the South River near Waynesboro, VA. The calibration approach presented in this study demonstrates the incorporation of fining direction regularization with a highly parameterized inversion driven by natural stimuli, to develop several realistic realizations of hydraulic conductivity fields that reflect the depositional history of the system. Specifically, we calibrate a model with 365 unique material zones to multiple flood events recorded in a dense well network while incorporating possible fining sequences consistent with the depositional history of the riverbank. Over 25,000 individual simulations were completed using calibration software and a cloud platform specifically designed for highly parallelized computing environments. The results of this study demonstrate the use of fining direction regularization during model calibration to generate multiple calibrated model realizations that account for the depositional environment of the system.
