“…Similar to the results of this study, Bartsch et al (2014) show that in the case of a monsoonal catchment in South Korea, the river changes from gaining flow from the adjacent aquifer into the river before a storm event to losing, groundwater recharge through the river bed after a storm event.…”

Seasonal shifts between wet and dry seasons cause marked changes in river flow regimes and therefore exchanges with the streambed surface. This seasonal variation is particularly apparent in tropical climates, which are characterized by strong differences between wet and dry seasons.However, fluxes between surface water and groundwater and the impacts of these interactions on per year. Groundwater withdrawal by households near the cross-sections was found to have a comparatively small effect on streambed fluxes, reducing the flux by up to 3 % during dry conditions, although this pumping did cause a reversal in the gradient to the stream for a short period (less than 12 hours) on one occasion during the dry season.

“…In addition, Bartsch et al (2014) indicated that vertical flow is dominant, whereas the La Vi modeling suggested more lateral flux into the river at the banks than vertical flow at the river bed. These results highlight the highly variable temporal and spatial aspects of riverbed fluxes (e.g.…”

“…As reported in [12], 'hyporheic flow is commonly distinguished from groundwater flowing near rivers by its bidirectional nature, i.e., hyporheic flow is exchanged back and forth across the streambed interface whereas groundwater recharge or discharge is considered to travel unidirectionally over much longer A C C E P T E D M A N U S C R I P T distances'. Water exchanges through the streambed are mainly induced by vari- 35 ations in bed topography, permeability and hydrological conditions [21]. Hyporheic pathways reach shallow depths (centimeters or decimeters) if developed beneath small bedforms whereas they infiltrate up to several tens, hundreds, or even thousands of meters when larger geomorphological features act as drivers [12].…”

“…Previous research has indicated that seasonal precipitation, as well as individual events, influences the hydrologic flushing of organic materials from the land surface (Jung et al, 2012;Lee et al, 2014). The longterm interdisciplinary research group TERRECO , has collected spatiotemporal terrestrial surface runoff measurements to calculate sediment yield , conduct dye tracer experiments to estimate soil structure and variably saturated flow and transport processes , and examine groundwater and surface water exchange on spatiotemporal fluxes and nearstream biogeochemistry (Bartsch et al, 2014). To quantify overland runoff, sediment transport, and soil loss from individual crops under specific management practices, it is critical to understand sustainable resource allocation and scenario implications in this agriculturally productive, complex terrain.…”

Abstract. Watershed-scale modeling can be a valuable tool to aid in quantification of water quality and yield; however, several challenges remain. In many watersheds, it is difficult to adequately quantify hydrologic partitioning. Data scarcity is prevalent, accuracy of spatially distributed meteorology is difficult to quantify, forest encroachment and land use issues are common, and surface water and groundwater abstractions substantially modify watershed-based processes. Our objective is to assess the capability of the Soil and Water Assessment Tool (SWAT) model to capture eventbased and long-term monsoonal rainfall-runoff processes in complex mountainous terrain. To accomplish this, we developed a unique quality-control, gap-filling algorithm for interpolation of high-frequency meteorological data. We used a novel multi-location, multi-optimization calibration technique to improve estimations of catchment-wide hydrologic partitioning. The interdisciplinary model was calibrated to a unique combination of statistical, hydrologic, and plant growth metrics. Our results indicate scale-dependent sensitivity of hydrologic partitioning and substantial influence of engineered features. The addition of hydrologic and plant growth objective functions identified the importance of culverts in catchment-wide flow distribution. While this study shows the challenges of applying the SWAT model to complex terrain and extreme environments; by incorporating anthropogenic features into modeling scenarios, we can enhance our understanding of the hydroecological impact.
