“…Drain parameters required by the DRN package include the drain elevation (ELEVATION) and the drain conductance (an adjustable multiplier times the parameter CONDFACT). Initial values of riverbed conductance were based on stream length (determined using a geographic information system), and average depth and width for the river reaches were based on mean annual streamflow from the USGS National Hydrography Dataset (U.S. Geological Survey, 2014) and regression equations determined by Magirl and Olsen (2009). The river and drain conductance parameters that control the effective rate of exchange of surface water with the aquifer system as a function of the head in the aquifer system, were assumed to be proportional to the area through which water can flow, and were adjusted during calibration using a multiplier.…”

“…For each model row and column, if a reach exceeded the annual flow threshold of 25 ft 3 /s, then a RIV cell was simulated at the model layer where the lowest downstream reach elevation existed (plus a 0.1 ft upward offset to ensure no computational problems when rivers and drains have head controlling elevations too close to the NWT dry cell condition). The lowest elevation downstream reach was specified as the value for the RBOT, and STAGE was set to this elevation plus the associated depth of water estimated by Magirl and Olsen (2009) for the NHD. For each stream reach simulated using the RIV Package, area was estimated as the length of the wetted perimeter (computed from NHD estimates of top and bottom width and depth of water) times the length of the reach intersecting the model grid.…”

Brazilian waterways link the interior of South America to industrial regions and coastal deep-water ports in Brazil, Argentina, and Uruguay, enabling the efficient flow of raw material as grain and ore. Nevertheless, the potential of the inland waterborne transport in the country is not fully explored. One of the main factors contributing to this scenario is the lack of specific research, field surveys, and operational methods. The navigation is mostly performed using few data (e.g. bathymetric data), which is not consistent with modern, competitive and safe waterways. This work analyzes hydrodynamic modeling and operational methods used worldwide and applied to navigation. It was identified that few methods for inland waterway navigability assessment in Brazil are used; they are sparse on specific problems and the methods used are often concepts of marine navigation and approach channels. This thesis presents a survey in how to assess the navigability capacity of rivers by a 2D fast-time vessel-current interaction model. The developed model uses Eulerian flows and a Lagrangian ship tracking approach, coupling river features (e.g. velocity field) and ship characteristics (e.g. dimension, maneuverability), calculating the resultant linear and angular momentum, thus measuring the ship motion at critical points for navigation. The German section of the Rhine River was used for the model verification and the Brazilian stretch of the Paraguay River as case study. Field measurements are necessary as input data and were processed to determine the navigation potential of rivers. According to the results, the model was able to reproduce satisfactorily the navigation of ships on the Rhine River. Then, studies of critical regions for navigation in the Paraguay River were carried out. It was possible to analyze the influence of parameters of vessels and channels that most impact the navigation capacity, such as the velocity, mass, and curvature radius. Therefore, one can use the model results for decision making policies to optimize the design and management of inland waterways.

“…The simulated quantity of water moving between the groundwater and surface-water systems is equal to the product of streambed conductance and the simulated head difference between the stream and underlying model HGUs. Initial values of streambed conductance were based on stream length (determined using GIS) and width (Magirl and Olsen, 2009), estimated streambed hydraulic conductivity, and streambed thickness. Initial estimates of streambed hydraulic conductivity were based on Hansen and others (1994) and adjusted during model calibration.…”

A regional, three-dimensional, transient numerical model of groundwater flow was constructed for the Yakima River basin aquifer system to better understand the groundwaterflow system and its relation to surface-water resources. The model described in this report can be used as a tool by watermanagement agencies and other stakeholders to quantitatively evaluate proposed alternative management strategies that consider the interrelation between groundwater availability and surface-water resources. The model was constructed using the U.S. Geological Survey finite-difference model MODFLOW. The model uses 1,000-foot grid cells that subdivide the model domain by 600 rows and 600 columns. Forty-eight hydrogeologic units in the model are included in 24 model layers. The Yakima River, all major tributaries, and major agricultural drains are included in the model as either drain cells or streamflow-routing cells. Recharge was estimated from previous work using physical process models. Groundwater pumpage specified in the model is derived from monthly pumpage values previously estimated from another component of this study. The pumpage values include estimates for wells with standby/reserve rights that are used in drought years. The model was calibrated to the transient conditions for October 1959 to September 2001. Calibration was completed by using traditional trial-and-error methods and automated parameter-estimation techniques. The model simulates the shape and slope of the water table that generally is consistent with mapped water levels. At well observation points, the average difference between simulated and measured hydraulic heads is-49 feet with a root-mean-square error divided by the total difference in water levels of 4 percent. Simulated river streamflow was compared to measured streamflow at seven sites. Annual differences between measured and simulated streamflow for the sites ranged from 1 to 9 percent. Calibrated model output includes a 42-year estimate of a monthly water budget for the aquifer system. Five applications (scenarios) of the model were completed to obtain a better understanding of the relation between pumpage and surface-water resources and groundwater levels. For the first three scenarios, the calibrated transient model was used to simulate conditions without: (1) pumpage from all hydrogeologic units, (2) pumpage from basalt hydrogeologic units, and (3) exempt-well pumpage. The simulation results indicated potential streamflow capture by the existing pumpage from 1960 through 2001. The quantity of streamflow capture generally was inversely related to the total quantity of pumpage eliminated in the model scenarios. For the fourth scenario, the model simulated 1994 through 2001 under existing conditions with additional pumpage estimated for pending groundwater applications. The differences between the calibrated model streamflow and this scenario indicated additional decreases in streamflow of 91 cubic feet per second in the model domain. Existing conditions representing 1994 through 2001 were p...
