RIVER DISCHARGE AND DEPTH ESTIMATION

Номер: US20180010936A1
Автор: Holland Kenneth Todd, Simeonov Julian A.
Принадлежит:

Embodiments relate to estimating river discharge and depth. Initially, observed velocities are used to generate a maximum velocity streamline for a river section, which is then used with an observed shoreline to construct a streamline curvilinear grid. The grid is used to interpolate scattered velocity data points, which are used with a bottom friction of the river section to approximate mean total head slope values. A least squares minimization scheme is applied to a velocity-slope relationship to estimate a bottom friction and discharge coefficient by fitting a difference in the predicted mean total head elevation values between upstream and downstream ends of the river section to a respective ζ-average of the measured total head values of the river section. Discharge of the river section is determined based on the coefficient and a velocity-depth relationship and then used to generate a river forecast. 1. A method for estimating river discharge and depth , the method comprising:receiving observed velocities from a velocity sensor, wherein the velocity sensor remotely senses the observed velocities from a river section;using the observed velocities to generate a maximum velocity streamline for the river section;constructing a streamline curvilinear grid based on the maximum velocity streamline and an observed shoreline of the river section;using the streamline curvilinear grid to interpolate gridded velocity data points on the curvilinear grid;predicting mean total head elevation values and mean total head slope values for the river section based on the gridded velocity data points and a bottom friction of the river section;receiving observed surface elevation values from a surface elevation sensor, wherein the surface elevation sensor remotely senses the observed surface elevation values from a river section;estimating measured total head values of the river section based on gridded velocity data points and the observed surface elevation values;applying a least ...

Using spatial information with device interaction

Номер: US20150019162A1
Автор: Allen Ming-kuang Han, SR., Dennis Hodge
Принадлежит: Amazon Technologies Inc

The amount of resources needed for an electronic device to track and/or interact with a user is reduced by utilizing a predicted relative position of that user. In some embodiments, a full 360° scan is performed using at least one image capture element to locate a primary direction to a user of the device. Once this direction is determined, a smaller range (e.g., 45°) centered around that direction can be used to capture, analyze, or provide information for the user. As the user moves, the determined direction is updated and the range adjusted accordingly. If the user moves outside the range, the device can increase the size of the range until the user is located, and the range can again be decreased around the determined direction. Such approaches limit the amount of image or audio information that must be captured and/or analyzed to track the relative position of a user.

The system of claim 1 , wherein the accelerometer is located at a point of suspension of the line.3. The system of claim 1 , wherein the line comprises a weight that causes the line to sink within the body of water.4. The system of claim 1 , wherein the body of water is moving.5. The system of claim 1 , wherein the depth of the line is outputted to an electronic screen.6. The system of claim 1 , wherein the depth of the line is equal to the amount of dispensed line multiplied by the cosine of the angle of displacement.7. A system for detecting an amount of line to dispense to a desired depth of a body of water claim 1 , the system comprising:a. a fish finder for finding one or more fish at a depth within the body of water;b. an electronic reel for dispensing line;c. an accelerometer coupled to the line and ...
