Abstract/Description
-
When a liquid drains through a hole in a container, a vortex may form between the surface and the drainage hole. An interesting phenomenon occurs in the presence of two drainage holes. Only one vortex forms, while the other hole will mostly drain as sink flow. In addition, the vortex can switch between one hole and the other with regular periodicity. The primary goal of this study is to measure this periodicity under varying conditions (height of water in the container, diameter of the...
Show moreWhen a liquid drains through a hole in a container, a vortex may form between the surface and the drainage hole. An interesting phenomenon occurs in the presence of two drainage holes. Only one vortex forms, while the other hole will mostly drain as sink flow. In addition, the vortex can switch between one hole and the other with regular periodicity. The primary goal of this study is to measure this periodicity under varying conditions (height of water in the container, diameter of the drainage holes, and distance between drainage holes). Additionally, a study concerning the volume flow rates of vortical vs. sink flow out of the drainage holes was conducted. In the case of two drainage holes, when the height of the water was decreased in the container, the diameter of drainage holes decreased, or the distance between drainage holes was increased, the switching period was shown to decrease.

Drainage waters leaving the Everglades Agricultural Area (EAA) have been implicated as having adverse effects on the receiving Water Conservation Areas (WCAs) and Everglades National Park (ENP). The objectives were to quantify and describe the rainfall and drainage events, characterize their effects on the water table system, and determine any relationships between the open channel drainage system and the field water tables on farms in the EAA.

Show moreDrainage waters leaving the Everglades Agricultural Area (EAA) have been implicated as having adverse effects on the receiving Water Conservation Areas (WCAs) and Everglades National Park (ENP). The objectives were to quantify and describe the rainfall and drainage events, characterize their effects on the water table system, and determine any relationships between the open channel drainage system and the field water tables on farms in the EAA. Water table rise in the soil profile from rainfall averaged a ratio of 10.6:1. Traditional expectations of field drainage behavior to channel gradients were not apparent. Field observation well drainage rates showed no direct relationships to distances across the farm or to the main station pumping rate. Due to the similar field water table responses under varying drainage scenarios, the organic soil, open channels, and the underlying geology were determined to function as an integrated system with respect to the movement of water.

Abstract/Description

The Village of Tequesta typifies an older storm water system. The infrastructure for the system has not kept up with development within the community. The design was for the conditions at the time of initial development. The levels of services provided are pertinent to establishing a direction and long term goals under current conditions. The existing seven and a half miles of conduit was modeled for a 25 year 24 hour storm. The rainfall amount simulated for the Tequesta area is 10.48 inches...
Show moreThe Village of Tequesta typifies an older storm water system. The infrastructure for the system has not kept up with development within the community. The design was for the conditions at the time of initial development. The levels of services provided are pertinent to establishing a direction and long term goals under current conditions. The existing seven and a half miles of conduit was modeled for a 25 year 24 hour storm. The rainfall amount simulated for the Tequesta area is 10.48 inches within a tidal area. The effects of the tide and the conditions of the conduit system lead to a realization that surface drainage is deeply affected by the tidal ranges associated with storm events.

Show moreDuring the Progressive Era, technical experts--state and independent engineers, United States Department of Agriculture scientists, and United States engineers increasingly influenced drainage and reclamation policy in central and southern Florida. Engineers agreed with the general method of drainage but at times disagreed over engineering specifics. The federal, state and local govemments were aware of the benefits associated with internal improvements, at the same time, however, they frequently fought over their control. Between the mid-nineteenth century and the early 1900s, drainage engineering knowledge and technology increased along with the role of the engineers. As a result, Florida's Progressive Governor Napoleon Bonaparte Broward began a state-financed and state-managed effort to drain and reclaim the Everglades in 1905. The role of the state engineer, however, differed from the expert described by historian Robert H. Wiebe, in that the engineer was not an independent policy-maker. The state engineer was always subordinate to the Florida Legislature and the Board of Trustees of the Internal Improvement Fund, including the Governor of Florida.
