A device comprising a corkscrew; a substantially flexible shaft operably attached to the corkscrew at a first end of the shaft; and one or more protrusions extending from the shaft between the first end of the shaft and a second end of the shaft. Methods of using the device are also disclosed.

Electric Generating Ecological Flood Control System which consists of selective collector, pressing pipeline, exiting collector, electric generator which is differs that pressing pipeline is lay under the bottom of the river or on the bottom of the river or in the water or above the water, where through the pressing collector carries out diversion of flood waters outside the area of possible flooding zones, while the regulation of amount and speed of water flows carries out according to additional leading one device regulative armature, that installed on pipeline and done with possibility of regulation exiting ability.

A reservoir (102) near an ice cap (104), and a graded terrace network (116) on the surface of the ice cap (104). The graded terrace network (116) collects runoff water across a wide area, both within the limits of the reservoir's (102) ice cap natural catchment area (112), and beyond it in the ice cap non-catchment area (114). The graded terrace network (116) directs the collected water into the ice cap natural catchment area (112) and from there it drains into the reservoir's ice-free catchment area (106), and then into the reservoir (102). This increases the volume of water stored in the reservoir (102). This additional stored water is used to power a hydroelectric power station (300) and for other uses. A second reservoir (406), connected to the reservoir (102) by a water pump (402) and a second hydroelectric power station (410), adds additional water storage and power generating capacity.

This invention is a device for creating tidal action in a terminal lake. A first aspect involves staggering of input and output from the terminal lake, such that the level of the lake rises and falls on a daily basis to simulate tidal action. A second aspect involves the creation of a berm and islands, with a system of pumps and drains filling and emptying a series of holding ponds, creating an even greater “reach” of the tidal action. This tidal action allows for the growth of mangrove forests, which prevent land-based predators such as coyotes from accessing bird nests on the islands, as well as keeping the “playa” wet enough so that local wind does not pick up playa sediment and create toxic dust storms. The toxic upper 3″ of the “playa” is bulldozed to create the berm, islands, and access roads which bisect the newly-created intertidal zone.

The present invention provides a low-energy coastal beach restoration method, comprising: constructing a convex beach berm, determining an aspect ratio of the beach berm edge, determining a beach face slope, performing sand replenishment, determining the dredging zone and dredging depth, and determining the steps of building a sediment groin. The present invention utilizes the feature of the convergence effect of the wave energy on the headland, artificially constructs a convex headland shaped beach berm, and determines the required beach face range and slope according to the convex beach berm edge. During beach restoration, dredging around the beach face, while reducing mud sources and increasing the nearshore water depth, it also builds a convex nearshore terrain, which effectively increases the wave energy at the restoration site and improves the coast muddy situation of low-energy coasts.

This invention provides a method and system for abating flooding that uses retention or detention ponds that require less surface area than prior art methods. The invention comprises at least one deep but narrow pond or water storage basin that can be pumped down during non-flood periods to an adjacent or remote water body. In one embodiment, the invention further comprises a levee to forms part or all of the water storage basin. The water levels in the water storage basin are controlled through a series of sensors, gauges, and/or valves either manually or automatically both for flow coming into the water storage basin during peak levels in an adjacent or remote water body and after peak elevations.
