The Chesapeake Bay is a marine aquatic life zone biome. This estuary is a mixture of salt water and fresh water. This is a sub biome of the Aquatic. The Chesapeake Bay is the largest estuary in the United States and third largest in the world. An estuary is a body of water where the salt water of the ocean mixes with the fresh water of rivers and streams. The Bay is 200 miles long and flows through the states of Virginia and Maryland. More than 150 rivers, creeks, and streams flow into the…

Fresh water availability is a high determining factor in the survival of life within an ecosystem. What is the purpose of a lake, when it’s unable to fulfill its ultimate niche? Strain and restricted capacity for biodiversity, habitat, and suitable drinking water will undoubtedly occur in the event of an imbalance. Lake Winnipeg served as a body of freshwater that has continually supported it`s community. It has served as a source of commercial fishing, transportation, recreation, and spiritual…

The Colorado River transects the Colorado Plateau. The Colorado River is ranked the fifth largest river in the United States, and is often referred to as the Nile of North America. This nickname describes its arid location and the vast human population that relies upon it (Kammerer, 2005). Despite its size, fluctuations in Colorado River stream flow are sensitive to the seasonal and annual changes in precipitation and temperature typical in arid systems. Long periods of below-average…

most producers manage one hundred and fifty or less acreage. Some farmers use the crawdad ponds for the growing rice, which is another major part to Louisiana’s agricultural industry at, other times of the year. The Atchafalaya River and its river basin are extraordinarily beautiful with the swampy scenery and the animals in this scenery. This is quite amazing there are egrets and alligators which help each other in the process of symbiotic relationships. The egret benefits form the alligator…

CHAPTER ONE 1. INTRODUCTION 1.1. BACKGROUND AND JUSTIFICATION Pan African Orogen (PAO) was formerly introduced by Kennedy (1964) to designate the peak of a wide spread orogenic thermo-tectonic episode characterized by intense period of reactivation and crustal formation. The term Pan African Orogen was used to describe the structural differentiation of Africa into cratons and mobile belts during the Neoproterozoic to earliest Paleozoic time (Kennedy, 1964). However, Kröner (1984) reformulate…

so forth, away from these protected areas. These recreational spaces would also be somewhat frequent in maintenance, either by volunteers or hired city-workers, or to ensure cleanliness and well-being. Furthermore, I would ensure that little to no drainage from the rainwater drains flows into the smaller creeks of the watershed as there is possible pollution from nearby urban areas, such as oil on roads and other possible run-off which can harm the biodiversity in small stream ecosystems.…

which helped contribute to the success of the Maya people (Toledo). The area that the Maya consumed is sometimes called the Yucatán Peninsula and expands from low coastal plains with everlasting rivers, and even into higher elevated uplands, where drainage is mostly in the ground itself and water is seasonally sparse. There are many coinciding lines of evidence that show that dry conditions split up the Maya Lowlands and match with significant…

Fast forward to today and the now named East Maui Irrigation system consists of 388-separate intakes, 24-miles of ditches and 50-miles of tunnels, as well as inverted siphons, numerous small dams, pipes, flumes and 8-reservoirs, spanning 39 drainage basins. A civil engineering landmark, the system now brings billions of gallons of water from the rainy side of Maui to the fertile growing fields and communities on the dry…

rock in place. Then, when rains do occur, they sweep enormous amounts of debris down the sides of the mountains through city streets and even to the front doors of peoples’ houses. A system of debris basins have been built to catch material sliding down before it reaches people’s homes. The debris basins fill up and then need to be emptied. McPhee’s book ends with the strangest scene of all: trucks lugging rocks back up the mountain, where they might slide right back down…

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…
