## Abstract

A submersible sieve apparatus provided with an exoskeletal frame enveloping a filter element and a detached post-filter backing; positioned to strain a lotic stream of entrained sediment prior to or upon being deposited. The frame can positioned and manipulated for greater efficiency. The filter and backing will take the shape of the frame and the backing may or may not be attached.

## Claims

### Claim 1

A new submersible sieve apparatus configured to be submerged into a channel of liquid, to be used as a, full gradient spectrum, lotic strainer to entrap entrained sediment, the sieve comprising:
an exoskeletal frame made from a pliable metal encased in a light weight polypropylene material that allows for the frame to take and maintain a shape for placement in the lotic channel under stress;
a filter element of measurable non-zero partial impedance to liquid and having a plurality of passages therethrough, wherein the passages vary in size to provide an irregular surface, supported and enveloped by the frame; and
a detached post-filter backing adjacent the filter element, having no passages therethrough, supported and enveloped by the frame and adjacent filter element.

### Claim 2 (depends on 1)

The submersible sieve apparatus of claim 1 wherein the exoskeletal frame is configured to be constructed as a rectangular shape and size not being larger than the lotic channel upon insertion into the lotic channel, the sieve thereby creating a plurality of evenly distributed openings, wherein apertures of the openings are configured to contain contents with non-zero impedance of the lotic channel therethrough.

### Claim 3 (depends on 1)

The submersible sieve apparatus of claim 1 wherein the detached post-filter backing is constructed from a light weigh and non-porous material that is configured to allow the detached post-filter backing to conform to the shape of the lotic channel.

### Claim 4 (depends on 1)

The submersible sieve apparatus of claim 1 wherein the filter element is constructed from a lightweight and pliable material, the filter element being configured to conform to the shape of the lotic channel.

### Claim 5 (depends on 4)

The submersible sieve apparatus of claim 4 wherein the frame has a plurality of evenly distributed openings, wherein apertures of the openings are configured to be sufficiently wide to securely contain contents while maximizing lotic stream therethrough.

### Claim 6 (depends on 1)

The submersible sieve apparatus of claim 1 wherein the filter element is configured to be proportional in size and shape to fit within said frame.

### Claim 7 (depends on 2)

The submersible sieve apparatus of claim 2 wherein the detached post-filter backing is proportional and matching in size or shape to the filter element, wherein the filter resides in a side-by-side position with the detached post-filter backing.
