Neural Operator Models as Applied to Fluid Flow Systems and Real Ocean Dynamics
… for reproducing and predicting classic fluid flows and simulations of realistic ocean dynamics. We first briefly evaluate the capabilities of such deep neural operator models when trained on a simulated two-dimensional fluid flow past a cylinder. We then investigate their application to …

Investigation of salinity and nutrient characteristics of two groundwater based flow systems on Virginia's Eastern Shore
… samples indicated the presence of two horizontal flow systems. The deeper flow system contained freshwater flowing seaward from upland areas. The shallower system contained saline water recharged by the tides and concentrated by evaporation. Salinity measurements and positive vertical (0.019-0.046 …

Methods Development and Validation for Large Scale Simulations of Dense Particulate Flow systems in CFD-DEM Framework
… in simulating a large variety of particulate flow system. This Eulerian-Lagrangian technique tracks all the particles included in the system by the application of point mass models in their equation of motion. CFD-DEM is a more accurate (and more expensive) technique compared to an …

Mathematical Modeling of the Movement of Heat, Water, and Solutes in Two-Dimensional, Saturated-Unsaturated, Surface Water - Groundwater Flow Systems
… heat, and solutes in surface water-groundwater flow systems was developed. The model has been verified by comparison with analytical solutions and field results. The model was also used to study two generalized, but hypothetical situations; the first was a regional stream-aquifer system, and the …

An examination of biological phosphorus removal using bacterial counting and poly-β-hydroxybutyrate analysis in batch and continuous flow systems
… Bacterial populations in both a continuous flow UCT (University of Cape Town) system and batch reactors were examined by direct counting using a well known staining procedure (Neisser staining), and a microscopic counting method developed by Cech and Hartman (1993). Substrate utilization was …

Hydrogeology of the Shell Creek area, Mountrail County, North Dakota
… of the area.</p> <p>There are four magnitudes of flow systems observed in the Shell Creek area: (1) very small magnitude flow systems, a few hundred feet wide, characterized by seasonal variations in the flow, rapid flow of water through the system and bicarbonate-rich waters; (2) small magnitude …

Groundwater flow, hydrochemistry, and uranium deposition in the Powder River Basin, Wyoming
<p>The relation between regional groundwater flow, hydrochemistry, and uranium distribution in the Powder River Basin indicates that uranium was deposited during the Tertiary Period in groundwater recharge areas where the groundwater changed from a sulfate-bicarbonate water to a bicarbonate-rich …

Groundwater of the Spiritwood Lake area, Stutsman County, North Dakota
… All forms of energy involved in groundwater-flow systems can be expressed in terms of potential. Gravitational, hydrostatic-pressure, velocity, thermal, chemical, and “other” potentials exist for every point in a groundwater-flow system. In the potential approach to groundwater each potential …

Surface Effects of Ground Water Flow Patterns - Bottineau and Mountrail Counties, North Dakota
<p>In the resolution of patterns of groundwater flow, certain surface expression is noted as being helpful. Vegetation has been used in other areas as an indicator of the chemistry of groundwater, but this type of exploration may be expanded to include physiography as well as vegetation. </p><p>The …
