STEPWISE CREATION OF GREEN AREA PATCHES, DRY CANALS DIGGING, NEARBY WETLANDS AND THEIR LINKAGES

Unfolding here is a stepwise process that needs to be taken up by a particular team in an area to create various green patches, various series of dry canals complex networks, various numbers of wetlands nearby green patches and linking these with each other. Each paragraph in an orderly and continuous way leads up to the process ahead.

First of all, one needs to survey a particular land and analyse to arrive at a conclusion whether or not for any of the right reasons it is really possible, feasible and practical to create green patch areas, dig up dry canals, a number of wetlands and connect these in a particular area. To do this, one needs to assess a local land for its topography, understand the quality of available soil types, assess the water table depth that exists there, select low lying flood prone areas to which water might move towards within that land piece, select promising fertile locations where greenery can flourish or could be turned into green patch areas in that land piece, analyse changing rainfall patterns, changing rainfall intensity, analyse flood patterns, assess low lying routes which can be dug to create dry canals through which water can automatically & naturally reach the green area patches at times of flood, or also shall reach various wetlands, assess and analyse effect of chosen ways of undertaking this activity on the various biological beings, local wildlife, ecosystems and available community resources.   

Second comes the decision at where multiple green patch areas or dry canals or wetlands will exist within available low lying but flood prone areas, this in turn calls for doing a bit of brainstorming coupled with a series of strategical planning. It follows deciding a good flood resistant and drought tolerant mix of various herbs, shrubs and trees that need to be planted, grown and maintained in such green patch areas to ensure that greenery survives in such patched areas during both --- dry and wet seasons. Also needs to be decided at this stage itself is that how much land and exactly which land piece with its location considerations needs to be left open as an open grassland and also as an open wetland to be able to serve as a water absorption zone. This way at this stage we finish designing a green area layout.   

Third follows the construction of a complex network of dry canals based on previous studies. While doing this the potential canal depths and widths must be rightly decided upon so that it can transport sufficient the flood water at the time of floods and in dry seasons such canals should only at a minimum use land. Within the dug canal various rock and permeable pieces should be dispersed so that such things can slow down the speed of the flowing water and the ground can absorb more of such flowing water through the canals. This way we are using a natural drainage technique.      

Fourth follows the construction of several small water bodies or wetlands near such green area patches. During heavy rains or flood seasons the excess water will accumulate in these wetlands and gradually water from these wetlands will be released into the connected dry canals. In dry season, canals will harvest rain water and irrigate these green patches. However before actually constructing a wetland one needs to decide as to what kind of a wetland might be suitable to be built in a particular area. For this one needs to decide whether one or more or a hybrid of all of the groundwater fed or rain water fed or river water fed wetlands will need to be created in a particular area. And also, if one or more of the marshes, swamps, bogs or constructed wetlands need to be constructed in a particularly chosen area. Also needs to be decided if different zones like deep water areas, shallow zones or vegetable buffers need to be created in wetlands to support the wildlife species and promote water retention capabilities.   

Fifth follows using harvested rain water from dug canals network or ponds or wetlands created near the green area patches to irrigate the green area patches using drip irrigation systems or other sustainable irrigation systems. To reduce water wastage greywater recycling systems should be used for irrigation.   

Sixth plant several plants on the ground especially in the grounds of the dug canals network, so that the soil does not erode away and soil erosion can be prevented and the soil fertility remain intact. In flood times, set up various sediments or silt traps in dug canals in order to prevent this system from clogging.    

Seventh follows encouraging the local community members to participate in creating and maintaining gardens in certain chosen areas of the green patched areas, canals and wetlands. For this they will have to plant, water the plants, take regular care of plants grown and maintain these in such garden areas. But this can only be done if the local community people are educated and made aware, in the same regards.     

For better results, one should collaborate with various experts like hydrologists, environmentalists, architects and civil engineers to design sustainable systems that have scheduled maintenance for green patches, dry canals, wetlands so that they function in short as well as in long run. To beautify gardens, one should use flood and drought adaptable local plant species that support local biodiversity.       

To succeed one should take the precautions by installing filtering systems that prevent entry of water pollutants with the water flowing into the green patches as it could damage the ecosystem, by designing the overflow channels divert excess water safely thereby preventing waterlogging in the green patches, by regularly monitoring plant and tree health prevent their dying especially in dry seasons when water level are low, by avoiding concrete but using natural material lining at the borders of the canal ensure better water absorption and heat accumulation minimization, especially during the dry seasons, by ensuring the design does not threaten existence of local wildlife or local birds, insects and small animals who make their habitat within the green patches.

To sum up, during flood seasons, water through canals reach the green patches and the nearby wetlands thereby saving life and during non-flood seasons, sustainable irrigation, greywater recycling and rainwater harvesting systems will irrigate and maintain health of the green patches and the canals act as natural drainage systems or corridors.   

Creating and managing several green area patches, dry canals and wetlands bodies nearby shall help mitigate the floods risks and at the same time help us improve and maintain an improved natural environment forever.
