Reports

The Utah Division of Water Resources contracted with Utah State University to document key scientific and policy information related to the current water conflict between Iron and Beaver Counties over the development of the Pine Valley Water Supply Project (PVWSP). The proposed PVWSP would pump groundwater from Pine Valley in Beaver County and pipe it southeast to the Cedar City region of Iron County served by the Central Iron County Water Conservancy District (CICWCD). Numerous concerns about the project have been raised by Beaver County and other interested parties. A number of these concerns are related to different understandings or …

Détérioration des infrastructures

Les municipalités et les personnes qu’elles servent dépendent des réseaux de conduites qui leur fournissent de l’eau potable de bonne qualité. Ces conduites sont souterraines, invisibles et souvent négligées.

Les résultats de l’évaluation globale de l’état des infrastructures hydrauliques ne sont pas bons. Prenons les États-Unis comme exemple :

· En 2009, l’American Society of Civil Engineers (ASCE) a publié un rapport sur les États-Unis et a attribué un D- aux infrastructures d’eau potable.

Deteriorating Infrastructure

Municipalities and the people they serve depend on pipe networks that provide safe drinking water. This piping is underground, out of sight, and often neglected.

Overall assessment of water infrastructure condition is not good. Using the US as an example:

• In 2009, the American Society of Civil Engineers (ASCE) issued a US report card and gave a D- to drinking water infrastructure.
• In 2017, the grade improved to a D.

Future Of Great Salt Lake Survey, Lisa W. Welsh, Joanna Endter-Wada, Karin M. Kettenring, Anna Mcentire

Reports

The Future of Great Salt Lake Survey was conducted in fall 2022 when state and global attention on Great Salt Lake was ramping up, following record lows of the elevation of lake water levels. In the survey, we asked Utahns their opinions on securing water for Great Salt Lake and focused on strategies that individuals, local communities, and the state of Utah could pursue. When it comes to how water is used and managed in Utah, there are multiple actors and institutions who all make decisions and have authority or ability to take different actions.

Predicting Flow Through The Causeway Of The Great Salt Lake Using Hydrodynamic Simulations And Artificial Neural Networks, Som Dutta, Brian Mark Crookston, Michael Rasmussen, Eric Larsen

Reports

At the Great Salt Lake, the northern and southern portions of the lake are divided by an east-to-west causeway that disrupts natural lake currents and significantly increases salt concentrations in the norther portion. To support management efforts to address rising environmental and economic concerns, the causeway was recently modified to include a new breach that typically exhibits a strong density-driven bidirectional flow pattern. To obtain much needed insights into the hydraulic performance of this hydraulic structure and the exchange between the two sections of the lake, a field campaign coupled with computational fluid dynamics (CFD) modeling and an artificial neural …

Information For Operation Of Water Supply Systems, L. Douglas James, Glen E. Stringham, J. Clair Batty

Reports

Introduction: Water requirements increase as more people use more water for domestic purposes. The increase is augmented as technological advances add to the water needs of agriculture and industry. Additional urban landscaping adds further to the demand. Simultaneously, the same forces increase demands for flood control, hydrelectric power, and navigation; and a more urbanized population want more flows preserved for productive natural environments, recreational use, and aesthetic enjoyment. The response over the years to these growing demands on water resources has been to supply increasing amounts of water and greater levels of development for other purposes by building more projects, …

Hydrologic Efficiency In Water Conservation, L. Douglas James

Reports

Introduction: The hydrologic cycle can be subdivided into three phases: 1)Humidity is transported within the atmosphere and becomes precipitation, and 2) Water moves downhill until eventually reaching the sea while all the time 3) Evapotranspiration returns exposed moisture to the atmosphere. During its movement, flowing water transports suspended sediments and dissolved minerals to reshape landforms and redistribute the mineral composition of the earth's surface throughout geologic time. It is during the second phase that flowing water can be diverted for uses that generally add to evaportranspiration (through consumptive use) and transport (through waste disposal). The water resources development that serves …

Draft Tampa Bay Interagency Seagrass Monitoring Program Training And Field Manual, Walt Avery, Roger Johansson, J. J. Pacowta

Reports

To insure quality assurance of the data collected among the various agencies, a training session is held each fall immediately prior to baywide TBISP monitoring. The goals of the session are to 1) determine the variability of the data collection among the agencies and to minimize this variability and 2) assess the repeatability of a seagrass investigator in determining species composition, abundance, density, and height. The purpose of this manual is to provide a seagrass researcher with information concerning TBISP protocols and results.

Data Summary From The Tampa Bay Interagency Seagrass Monitoring Program Through Year 2008, Walt Avery, Roger Johansson

Reports

In 1997, the TBEP coordinated the creation of a bay-wide fixed transect seagrass monitoring program. The primary goal of the program is to document temporal and spatial changes in seagrass species composition, abundance, and distribution along a depth gradient. Several bay area agencies committed personnel and equipment to the program. Data collection from 60 transects began in 1998. Currently, 62 transects are monitored due to revisions in transect selection and location. This paper presents a general summary of Tampa Bay seagrass trends from 1998-2008

Long-Term And Seasonal Trends In Phytoplankton Production And Biomass In Tampa Bay, Florida., J.O. R. Johansson

Reports

Phytoplankton production is a basic process in aquatic ecosystems that converts inorganic carbon into organic matter and provides an important indicator of trophic state. The City of Tampa Bay Study Group maintains a 32 year long monthly record of phytoplankton production rates and biomass (chlorophyll-a) in Hillsborough Bay (HB) and Middle Tampa Bay (MTB), and a recent record during the last nine years for Old Tampa Bay (OTB). Production is measured using the classic in situ 14C method with samples incubated vertically in the water column. Annual production rates during the most recent decade are about 410gCm-2 for HB, 350gCm-2 …

The final project monitoring results show that the manatee grass transplanting effort was completed successfully. First, the donor site monitoring indicated that disturbances caused by harvesting were fully mitigated within the two year study period. Second, about 1300m2 of manatee grass were established in an area previously devoid of this species. Third, at the end of the study period the per unit area above ground biomass of the restored manatee grass in several of the planting plots was similar to, or may have exceeded the biomass of the donor grass at the time of harvest. Finally, several of the restored …
