“…This was performed to facilitate linking of existing models, such as regional‐scale groundwater models (e.g. Rumman and Payne, ; Christenson et al ., ; Paschke, ; Gannett et al ., ; Mashburn et al ., ). Beyond the overlap area, the original functionality of each model is retained.…”

“…Available published watershed‐scale hydrologic models include TOPography‐based hydrological model (TOPMODEL) (Beven et al ., ), MODFLOW‐based Hydrologic Modeling System (MODHMS) (Panday and Huyakorn, ); the Systeme Hydrologique Europeen model (SHE/MIKE‐SHE) (Butts and Graham, ), the Integrated Hydrology Model (VanderKwaak, ; Loague et al ., ), the Catchment Hydrology model (Camporese et al ., ), Parallel groundwater Flow (ParFlow) (Kollet and Maxwell, ), GSFLOW (Markstrom et al ., ), and SWAT (Neitsch et al ., ). As calibrated SWAT and MODFLOW models are available for the region (Gannett et al ., ; Records et al ., ) which simulate surface hydrology and groundwater hydrology, respectively, this study coupled the two models to integrate surface and subsurface hydrological processes. Furthermore, future efforts will employ the coupled model to assess nutrient pollution (Records et al ., ) in the land surface/subsurface/stream system of the watershed, and from the afore‐mentioned watershed‐scale hydrologic models only SWAT simulates nutrient fate and transport.…”

Interaction between groundwater and surface water in watersheds has significant impacts on water management and water rights, nutrient loading from aquifers to streams, and in-stream flow requirements for aquatic species. Of particular importance are the spatial patterns of these interactions. This study explores the spatio-temporal patterns of groundwater discharge to a river system in a semi-arid region, with methods applied to the Sprague River Watershed (4100 km 2 ) within the Upper Klamath Basin in Oregon, USA. Patterns of groundwater-surface water interaction are explored throughout the watershed during the 1970-2003 time period using a coupled SWAT-MODFLOW model tested against streamflow, groundwater level and field-estimated reachspecific groundwater discharge rates. Daily time steps and coupling are used, with groundwater discharge rates calculated for each model computational point along the stream. Model results also are averaged by month and by year to determine seasonal and decadal trends in groundwater discharge rates. Results show high spatial variability in groundwater discharge, with several locations showing no groundwater/surface water interaction. Average annual groundwater discharge is 20.5 m 3 /s, with maximum and minimum rates occurring in September-October and March-April, respectively. Annual average rates increase by approximately 0.02 m 3 /s per year over the 34-year period, negligible compared with the average annual rate, although 70% of the stream network experiences an increase in groundwater discharge rate between 1970 and 2003. Results can assist with water management, identifying potential locations of heavy nutrient mass loading from the aquifer to streams and ecological assessment and planning focused on locations of high groundwater discharge.Base-flow fraction results are provided by the base-flow separator tool BFLOW (Arnold et al., 1995;Arnold and Allen, 1999) MODFLOW, Modular Ground-Water Flow; SWAT, Soil and Water Assessment Tool. 4428 R.

“…The benefits and the problems that are associated with these assumptions when evaluating model predictive uncertainty and data worth were discussed and compared to the nonlinear and more robust but computationally much more demanding Markov chain Monte Carlo method by Gallagher and Doherty (). Sensitivity analyses (see Hill & Tiedeman, ; Gannett et al, ; Masbruch et al, ; Rasa et al, ), influence statistics (see Hill & Tiedeman, ; La Vigna et al, ), and singular‐value‐decomposition‐based principal component analysis (see Doherty, ; Doherty & Hunt, ; Schilling et al, ) provide additional computationally efficient means to estimate the information content of specific observations or observation types. All these methods are based on the sensitivity matrices calculated with automated flow model calibration routines that are based on weighted multivariate objective functions.…”

Traditionally, groundwater and surface water flow models have been calibrated against two observation types: hydraulic heads and surface water discharge. It has repeatedly been demonstrated, however, that these classical observations do not contain sufficient information to calibrate flow models. To reduce the predictive uncertainty of flow models, the consideration of other observation types constitutes a promising way forward. Despite the ever-increasing availability of other observation types, however, they are still unconventional when it comes to flow model calibration. By reviewing studies that included nonclassical observations in flow model calibration, benefits and challenges associated with their integration in flow model calibration were identified, and their information content was analyzed. While explicit simulation of mass transport processes in flow models poses challenges, even simplified approaches to integrate tracer concentrations yield significantly better calibration results than using only classical observations. For a majority of calibrated flow models, observations of tracer concentrations and of exchange fluxes were beneficial. Temperature observations improved the simulation of heat transport but often worsened all other model outcomes. Only when temperature observations were made within 2 m of the surface water-groundwater interface did they have the potential to also improve flow and mass transport simulations. Surprisingly, many models were calibrated manually rather than with the widely available, mathematically robust and automated tools. There is a clear need for more systematic implementation of unconventional observations and automated flow model calibration as well as for more systematic quantification of the information content of unconventional observations. Plain Language Summary Traditionally, groundwater and surface water flow models, which are critical for water resources assessment, have been calibrated against only two classical observation types: groundwater levels and surface water discharge. In the past, it has repeatedly been demonstrated that these classical observations do not contain sufficient information to calibrate the parameters required for the simulation of groundwater and surface water flow systems. Owing to the rapid development of measurement techniques throughout the last three decades, however, many other observations of hydrological systems have become widely available. Despite this, observation types other than the classical ones are still unconventional when it comes to flow model calibration. The overall goal of this review is to identify optimal observation types and procedures for flow model calibration and hydrological predictions. We found that observations of tracer concentrations and exchange fluxes are beneficial for most flow models. Temperatures improve the simulation of heat transport but often worsen other flow model outcomes, unless temperatures are measured within 2 m of the surface water-groundwater interface. We identified a need for...

Until now, research achievements of groundwater such as groundwater to depth distribution, usage, the available amount of development, water quality have been written in the watershed units(25~250km 2 ). However, complex topography and geology, and the rivers of our country does not fit. And a clear management standards have not been able to present measures in groundwater quantity, water quality management such as rainfall, groundwater, utilization, water quality, pollution, etc. Therefore, in this study, the classification criterion of subwatershed unit(2.5~25km 2 ), which is suitable for topography and geology of Korea, for rainfall-rating, groundwater level-rating, groundwater pollution-rating, groundwater quality-rating presented and proved its efficiency by applying in Hampyeong-Gun area.
