Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley

Reports

The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …

Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand

Reports

Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.

Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …

Legal Symposium On Wetlands: An Executive Summary, Roger D. Anderson, David Garten, Ted Smolen

Reports

In 1969 the Virginia Institute of Marine Science published a report stating that although marshlands represented only one-half of one percent of the total area of the state, 95 percent of Virginia 's annual harvest of sport and commercial fisheries were dependent to some degree upon these valuable wetlands . The report went on to urge some form of public control over these vital areas in order to relieve some of the pressures created by dredging, filling, diking and bulkheading.

Recognizing the need to address this issue, the 1971 General Assembly passed House Joint Resolution Number 60, creating a Wetlands …

A Socio-Economic Environmental Baseline Summary For The South Atlantic Region Between Cape Hatteras, North Carolina And Cape Canaveral, Florida Volume Ii : Climatology, Virginia Institute Of Marine Science

Reports

The geographic area covered in this report extends from Cape Hatteras, North Carolina, on the north, to Cape Canaveral, Florida, to the·south. Included within this area are portions of the coastal areas of South Carolina and Georgia. All or portions of thirty coastal counties are included within the study area.

Estuaries in this area tend to be partially mixed due to relatively low runoff per mile of coast. The proximity of the Gulf Stream to the continental shelf and the low runoff combine to cause the salinity of the coastal water to be somewhat higher than that of the coastal …

A Socio-Economic Environmental Baseline Summary For The South Atlantic Region Between Cape Hatteras, North Carolina And Cape Canaveral, Florida Volume 1 : Physical Oceanography, Virginia Institute Of Marine Science

Reports

The paucity of oceanographic data on the continental shelf and in the estuaries south of Cape Hatteras, North carolina hinders attempts to document the oceanographic conditions. In general data are more available and conditions better understood in the estuaries than on the continental shelf.

The estuaries of the Southern Atlantic Bight have not been studied as extensively as the large embayments to the north. Generally the estuaries tend to be partially mixed since runoff and thus river flow is not great in these river systems. Both the distance the tidal effect is felt and the distance up the estuary that …

A Socio-Economic Environmental Baseline Summary For The South Atlantic Region Between Cape Hatteras, North Carolina And Cape Canaveral, Florida - Volume Iii: Chemical And Biological Oceanography, Virginia Institute Of Marine Science

The geographic area covered in this report extends from Cape Hatteras, North Carolina, on the north, to Cape Canaveral, Florida, to the south. Included within this area are portions of the coastal areas of South Carolina and Georgia. All or portions of thirty coastal counties are included within the study area.

From a chemical standpoint, the area is characterized by nutrient input from rivers, especially nitrogen, resulting in low phytoplankton production. Heavy detritus loads from adjacent salt marches keep the oxygen level in estuaries below saturation. These streams have little capacity to assimilate additional oxygen demand.

Zoogeographically, the area comprises …

Studies Of Certain Impacts Of Tropical Storm Agnes On The Chesapeake Bay And Its Tributaries - A Final Report On Activities, William J. Hargis Jr.

Reports

In the summer of 1972 Hurricane Agnes, spawned over the Yucatan Peninsula, developed in full force in the Gulf of Mexico, bulled its way ashore in Western Florida (and Southeastern Alabama) and spent its fury in the interior. It arrived in the Middle-Atlantic States as an Extratropical Storm. At every stage it was disruptive and destructive.

In the Chesapeake Bay Drainage Basin, Agnes was particularly spectacular even though her wind velocities were markedly reduced. In particular, she poured vast amounts of rain on an already saturated land. In rapid succession the James, the Potomac and the Susquehanna were driven into …

Water Salvage Potentials In Utah, Volume I. Open Water Evaporation And Monolayer Suppression Potential, Trevor C. Hughes, E. Arlo Richardson, James A. Franckiewicz

Reports

An estimate of the potential in Utah for evaporation suppression by the monolayer film method is presented. The model estimates evaporation suppression as a function of wind speed, a four parameter exposure factor, and reservoir size. The estimated suppression factors vary from 0 to 30 percent and average 11 percent of the statewide total annual evaporation. Estimates of May to October evaporation and suppression potential are calculated for each of the 227 impoundments in the surface water inventory. A forthcoming report in this series will examine the potential for evaporation suppression by thermal destratification. This procedure, which is already being …
