Water management

elevation (below sea level) of New Orleans city are the reasons that make it vulnerable. New Orleans city is near to the Gulf of Mexico and it is also on the Mississippi River. We know that one of the major causes of sea level rise is the increase in water temperature. And as long as humans keep doing activates that generate carbon dioxide, carbon emission will keep…

Santa Barbara’s Coastal Watershed divides into six sites: Carpinteria, Rocky Nook Park, Mission C, Maria Ygnacio, Atascadero and San Jose. All the sites are managed by a levee system, and half of these sites are empty; no water flows through them because it doesn’t rain frequently in Santa Barbara (typically only raining between 3-6 inches during the wet months, which is between November-March), but all empty at the Pacific Ocean, which is relatively close to the city (t-cep.org/floods).…

“With these grand structures, so numerous and indispensable, carrying so many waters, who indeed would compare the idle Pyramids or other useless, although renowned, works of the Greeks?” – Sextus Frontius in reference to Pliny. “It must be admitted, this is the greatest wonder the world has ever seen” – Pliny, NH XXXVI, 24, 123 Ancient Rome is famously known for its intricate water management systems such as its baths, artificial pools, reservoirs, irrigation channels and other similar…

built armored cars. They were thriving. The controversy started here because just four days before the dam collapsed, a federal mine inspector rated the dam “acceptable” and “satisfactory”. When the dam burst, over 130,000,000 gallons of black water flooded the towns below. During this incident 125 people were killed and over 1,100 people were injured. Of the 16 towns that were affected,…

Biofloc technology ensures sustainable aquaculture and protecting fish from variety of disorders and infections. Microbial flocs developed under the biofloc technology function as potential food sources for fish. Improved fish production, minimal water exchange and recycling of feed…

Introduction: Water and soil, are vital resources. In the arid region, they are experiencing a high degradation in quantity and quality by water erosion. the latter is a natural phenomenon, that evolves with the anthropic evolution and the climate severity, recent studies on the vulnerability to climate change in the Mediterranean region, indicate a trend towards increased aridity which accelerating water erosion (Berkane and Yahiaou 2007; Souadi 2011). Soil erosion by rainfall and runoff is a…

wastewater and improving water quality (Minhas et al., 2015), rehabilitating deforested watersheds and degraded landscapes (Parrotta, 1999). Monocultures for wood and fibre products are dominated in the tropics (Kanninen, 2010). Fast-growing, exotic and low-density wood species, such as Eucalyptus, Pinus and Acacia are largely used for timber, paper pulp, charcoal and fuel, because they have short rotation period and they have advantages in competing for light, nutrients and water resources over…

one of the most environmentally destructive forms of modern agriculture affecting mangroves directly [83]. Aquaculture destroys the mangroves to create shrimp ponds, reduce the ground water levels, and cause pollution to the surface water from the pond effluents [100]. Lack of long-term conservation and management of natural resources are the greatest shortcoming of shrimp aquaculture [40]. Researchers have noticed that the world’s mangroves will disappear in about 50 years if this trend…

utilizes water and gas injection, dislodging the oil and driving it to the surface. US Department of Energy stated that by using these two systems can leave up to 75% of the oil in the well. The best approach to further increase oil production is through the tertiary recovery technique which is Chemical enhanced oil recovery (CEOR). CEOR has been labeled as an expensive method and…
