Water Sources Management

Major treats:

  • A weed is a plant considered undesirable in a particular situation, “a     plant in the wrong place”. Examples commonly are plants unwanted in human-controlled settings, such as farm fieldsgardenslawns, and parksTaxonomically, the term “weed” has no botanical significance,

         In this recent years this river is overcrowded by the growth of weeds which cannot be destroyed easily .This weeds also served as a home to the mosquitoes which in turn invited the diseases in our home.

 Types of lake weeds

                       They are rooted in the bottom, but stems, foliage and flowers extend above the water surface like Cattail (Typha spp.), Besharam (Ipomea carnea), Common reed (Phragmites communis), American lotus (Nelumbo lutea), Water lily (Nymphaea odorata), Pickerel weed (Pontederia cordata), Arrowhead (Sagittaria spp.), Purple

Negative effects of weeds in water systems:

             The plants cause tremendous loss of water from water bodies like lakes and dams through evapotranspiration. Aquatic weeds have been found to severely reduce the flow capacity of drainage and irrigation canals thereby reducing the availability of water to the farmer’s field.

       A few examples of broadleaf weeds are clover, dandelion, and purslane. Some examples of grassy type weeds are nutsedge, pampas grass, and bermuda grass. Weeds can be further divided into annuals, biennials, and perennials.

 Sustainable methods:

         Chemicals:

            Herbicide spray or granules that are applied to the water or area following specific instructions.

      Effective at targeting specific weeds

    Less labor intensive

DREDGING:

A machine that displaces (and depending on the type, can remove) sediment layers.

   Moves the sediment thereby removing seeds, roots, and plants

   Removes a mucky bottom

   Can increase water depth

Deweeding Organization:

       To save the river from being polluted and being harmed there are methods that can be followed

The de-weeding drive undertaken by the public works department (PWD) recently at the Uyyakondan canal in the city to prevent mosquito menace, has escalated the maintenance cost by 12% than last year, with officials attributing it to the rapid growth of water hyacinth and waste water being let into the canal.

    To overcome such a situation the young volunteers can come front and organize a team to help to save the river from being lost off.

  • Garbage disposal:

River of garbage:

                          Trash can travel throughout the world’s rivers and oceans, accumulating on beaches and within gyres. … It is transported by rivers to the ocean, where it moves with the currents, and is often eaten by birds and fish, concentrating toxic chemicals in their tissues, and filling their stomachs, causing them to starve.

And also this river is now polluted by throwing garbage into it. This once again paves way for diseases and also affects the organisms that lives in it and fed with it.

The effects of illegal dumping:

A common method of illegal dumping is throwing garbage directly into a river or stream, this causes oceanic pollution and leads to the death of marine life. Waste that is dumped illegally often contains dangerous and toxic substances, which soak in all the oceanic oxygen.

            “Plastic can have a damaging impact on underwater life. Large pieces can trap animals but smaller pieces can be in advertently eaten. “Once digested, plastic can release toxic chemicals which are then passed through the food chain. These toxic chemicals, in high doses, could harm the health of wildlife.”

Sewage treatment:

   NOWADAYS this river is flowing along with the garbage in it which makes it more badly and useless for this the people in my locality can come up in collecting funds and help in promoting and restoring it. And also they can associate a team to clean up the river in order to save our resource.

WHO IS RESPONSIBLE?            

   If no government agency has the responsibility or resources to clean up the banks of a stream or its littered streambed, then it is the responsibility of nongovernmental organizations and private citizens to do so. There are many opportunities for private citizens to participate in river and stream cleanups. For example, the U.S. Environmental Protection Agency sponsors an “Adopt-a-Watershed” program. Many states have “green team” or “stream team” opportunities, such as Vermont’s Green-Up Day and Northern California’s Riverwat.

        Volunteers who participate in stream cleanups often report a rewarding experience. In addition to providing an aesthetic and environmental benefit, cleanups reconnect citizens and the community to the waterways that have been a vital part of the nation’s history and culture.

            Research has shown than people are more likely to behave in ways that preserve our waterways if they are clean in the first place. If a stream bank or shoreline already has litter, people are more likely to continue littering. Individuals can take the initiative by cleaning up streamside trash and by disposing of trash properly.
