Implementation and use of direct-flow connections in a coupled ground-water and surface-water model Implementation and use of direct-flow connections in a coupled ground-water and surface-water model
The U.S. Geological Survey's MODFLOW finite-difference ground-water flow model has been coupled with three surface-water packages - the MODBRANCH, River, and Stream packages - to simulate surface water and its interaction with ground water. Prior to the development of the coupling packages, the only interaction between these modeling packages was that leakage values could be passed...

A coupled surface-water and ground-water flow model for simulation of stream-aquifer interaction A coupled surface-water and ground-water flow model for simulation of stream-aquifer interaction
Ground-water and surface-water flow models traditionally have been developed separately, with interaction between subsurface flow and streamflow either not simulated at all or accounted for by simple formulations. In areas with dynamic and hydraulically well-connected ground-water and surface-water systems, stream-aquifer interaction should be simulated using deterministic responses of...

Effects of horizontal velocity variations on ultrasonic velocity measurements in open channels Effects of horizontal velocity variations on ultrasonic velocity measurements in open channels
Use of an ultrasonic velocity meter to determine discharge in open channels involves measuring the velocity in a line between transducers in the stream and relating that velocity to the average velocity in the stream. The standard method of calculating average velocity in the channel assumes that the velocity profile in the channel can be represented by the one-dimensional von Karman...

Coupled surface-water and ground-water model Coupled surface-water and ground-water model
In areas with dynamic and hydraulically well connected ground-water and surface-water systems, it is desirable that stream-aquifer interaction be simulated with models of equal sophistication and accuracy. Accordingly, a new, coupled ground-water and surface-water model was developed by combining the U.S. Geological Survey models MODFLOW and BRANCH. MODFLOW is the widely used modular...
