Wetland ecosystem is very sensitive to climate variation. Study on wetland ecosystem with respect to climate change will provide great information about water quality, water quantity, identification of sources of pollutants, impact on local flora and fauna with respect to changes in weltalnd ecosystem

yes it has many benefits in context of surface water level in wetlands. The detailed study will give information about ecosystem , water quality , flora and fauna in ecosystem.

Hello Pema, water surface analysis can be achieved by both looking at the quality and quantity. In terms of quality you look at the variation of different parameters like DO pH, temperature, total dissolved solids. When it comes to quantity you look at the fluctuations of water levels in the wetland.

Wetted area is a big factor in the design of surface flow wetland. If the water level drops drastically the microbiological activities will be reduced and thereby, the treatment capacity by the wetland will also be reduced. The survival of plants may be at a danger level if water level drops due to rapid increase of temperature. With the reduced water level, the DO volume will be affected. The climate change effect should be incorporated prior to design of a surface flow wetland.

Wetlands are Kidneys of natural eco system. Therefore data on Water Analysis can provide a guide to monitor the function of the Kidney to maintain a healthy the eco system.

Following publication shows an example on how to use Wetlands for multipurpse objectives.

This explains the Vision behind ancient irrigation technology in Sri Lanka where wetlands were the nucleus around which designs were formulated. Those projects sustained more than 2000 years and still functioning prducing healthy foods without polluting soil and water. It was a negotiation with the eco system rather than confrontaion as adapted now days.

Thanks, Dr. Mahinda Panapitiya! There are many useful examples on wetland treatment in your attachment. In many treatment wetlands, surface water treatment is final treatment process where final polishing of nutrient and metal removal is done. Keeping certain depth of water in that chamber is very important.

Thanks. By thew way I do not hold a PhD.

In my paper, I tried to explain the importance of the roles play by the Vision of the general public in using the reserach outcomes of professionals like you and me. According to my more than 30 yeras of experience with the small scale farmers in the Dry Zone of Sri Lanka, some of them have very creative out of box ideas. However as professionals, we should be open mind to general public who are not imprisoned in modern technologies like us. For an example, in 2002, one such idea proposed by a farmer in a project where I worked as a water management engineer accepted by the World Bank as the best water management approach suitable for South ASian Countries. The attached paper explained how ancient Irrigation Engineers conditioned by Buddhist vision perceived the eco system in using wetlands fort food production. Following note explains another such out of box idea backed with Buddhist Visioin, explaining how ancient farmers tackle Human Elephant conflicts which presently kills more than 100 farmers annually.

Interesting article, Mr. Mahinda Panapitiya. Innovative ideas do not need to be high tech ideas, very basic ideas can develop to an effective, cost efficient and eco-friendly alternative.

I would like to thank all experts for sharing your valuable comments and suggestions.

Of course you can use this as a climate change indicator. Change in inundation and water level in different time might be a climate change indication. Many of the other issues are already addressed in previous answers.

It also explains the physio chemical properties and their seasonal status.

In my view, local communities should become partners of research teams who developed advance technologies such as wetland,

One of the main hurdles we have to face in dealing with water while applying modern technologies like wetland treatment is the dynamic nature of water resource. This is not an issue in managing Land Resources because it is static and quantifiable in terms of area such as Hectare.

In the case of water, there is a need to create a similar Impression among users about the amount of availability. In the case of water, it is a Volumetric Impression. For an example, people residing in a particular river basin should be equipped with the constantly updating awareness about gallons of water which is available for them for cultivation and for their domestic use. As a result of that awareness, people naturally become motivated to save water using strategies such as rain fall harvesting. They also get motivated to replenish ground water aquifers by increasing vegetation cover of their homesteads or by building small wetlands within their lands to minimize runoff occur after rains.

In other words Rivers should be the nucleus around which development within the basins need to be planned with committed community participation.

Lack of Volumetric Impression about the water availability for cultivation among small scale farmers settled in large scale irrigation projects is the main is a main weakness in designs adapted during the last 2 century in countries in South Asia. Usually in those large scale projects developed main water source which is a big reservoir, is located far away from the farming areas. Solutions adapted by Ancient Planners to overcome this issue are decentralizing the water availability to small scale village tanks to capture local rain falls. Similar approach is now being adapted even in developed countries such as US. It is known as Dispersed Water Management.

As a result of this type of decentralization, local communities become partners of research teams who developed advance technologies such as wetland development. Otherwise they are just researches thesis reports available in libraries in Universities.

wetlands receives the water seasonally through river runoff and it carry sediments and sometimes waste water also. so water quality analysis will help to find the nature of environment may polluted or not.

climate change is vast concern due to climate change and developmental activities wetland getting degradation.

We now recognize that certain essential environmental and public resources are provided by the wetlands. They include important fish, waterfowl and other wildlife habitats, clean waste water, and track the devastating force of floods and storms. They also offer a wide range of leisure activities, including fishing, hunting, photography and watching wildlife. Since these and many other functions and qualities of wetlands are becoming more well recognized, wetlands are becoming more and more regarded as productive, important and restored properties. Due to it many functions wetland called "The kidney of the earth"

we need to protect and beware for our wetland.
