4.0 CHENNAI FLOOD MITIGATION MEASURES The mitigation measures have to address flood avoidance, flood tolerance, and flood resistance in an integrated way. The measures that are implemented and the new measures to be developed are meant to control causative factors like uncontrolled urban sprawl, loss of natural drainage, the inadequacy of the storm water drainage system, lack of maintenance of existing systems, increase in impervious surfaces and lack of coordination between stakeholders involved in implementing the measures. The measures could be broadly classified into structural and nonstructural measures. These measures include institutional, physical, socio- economic and environmental measures. 4.1 STRUCTURAL MEASURES The structural measures…

Hi, Aaron here from the Leiningen plantation in southern Brazil. We are witnessing, first hand, the world’s largest army attempt to take on 400+ men armed with farm supplies and tools, ANTS! Every few years, an ant colony will expand outside its normal exploring territory and move all the way across South America. This colony arises other colonies along the way and builds their army of mass destruction. This swarm can grow up to 2 miles wide, and 10 miles long. That’s 20 square miles!! This…

McNabs and Lawlor Island’s collectively measure at approximately 430 ha. There are several drainage channels on the island. These channels flow into Ives Cove, Finlays Cove, McNabs Cove, Wreck Cove, Timmins Cove, Cullition Point, and McNabs Pond. The channels are fed by gullies at higher elevations. Lawlor Island contains no major drainage channels because of the lack of gullies or depression zones on its surface. The Wolfville soils on the island provide good drainage, the riparian areas…

Daszkilewicz, 529312, 1 The earth roils in a toxic, acidic stream, and a thick sludge accumulates within it like corrosion on a battery. It chokes and kills all life that once lived in the vibrant and pristine water, eventually giving it the appearance of perpetually flowing orange paint. This isn't a scene from some horrific, imaginary planet that belongs in a nightmare or a science fiction movie, but one that has slowly invaded our very own Earth. The best way to combat acid mine drainage is…

Egypt has always been predominantly a desert country. 94.5% is desert, arid and semi-arid rangelands. The other 5.5% is known now as the Nile River Basin (El-Nahrawy, 2011). Flood waters from the Nile leave silt on the ground creating fertile soil that is productive in growth of vegetation. In 5000 B.C.E. Nomadic tribes settled this “black land”…

located in both Nassau and Suffolk county. All three basins had different shapes and drainage area sizes in order to determine an average performance from all the systems. To determine the effectiveness, the basins were analyzed in three different areas: Precipitation-Inflow relation, Runoff Hydrograph, and Rates of Filtration. The three basins analyzed were located in Deer Park, Westhbury, and Syosset. The Deer Park recharge basin has a drainage area of around 118 acres serving mostly…

Interpretation Acid-mine drainage occurs when sulfide-bearing waste rock and tailings come in contact with waters containing dissolved oxygen. The resulting oxidation reactions release associated metals and acidity, which may impact the biological community and significantly lower the pH of downstream waterways (Army, 2010). Released metals that are transported downstream may be removed from solution through precipitation of and sorption onto iron and manganese hydroxides. Attenuation of metals…
