|
 | The Buoy-Deployed Seeding System (BuDS) (Figure 1) was developed to take advantage of the natural ability of mature reproductive shoots of eelgrass (Zostera marina) to release seeds over a period of weeks, and offers a low-cost alternative method of planting eelgrass using seed that can replace or compliment broadcast seeding efforts (Pickerell et al. 2005). This system may offer several advantages over current seeding methods including: 1) it may more ... |

|
| As water resource projects become more and more complex, there is a growing emphasis on the ability to implement effective regional sediment management. A common goal of many regional sediment management (RSM) projects is the reduction of sediment loading from the watershed. This is usually accomplished by rehabilitation features such as grade control, bank stabilization, drop pipes, and land treatments. While these features are often implemented with the stated purpose ... |

|
| Effective facility infrastructure inspections are essential for a successful asset management program. They provide vital decision support information about current condition, future performance and reliability, and capital repair/restoration requirements. Some infrastructure assets are inspected using strictly regimented procedures at a specified frequency, but that approach is cost-prohibitive for most infrastructure domains, especially where failure does not present a compelling safety hazard. Abandoning certain inspection programs to reduce costs is not ... |

| ASTM International defines building performance as the in-service functioning of a building for a specified use (ASTM E1480-92). The term refers to how effectively, safely, and efficiently a building performs its mission at any time during its life cycle. A building's performance state, which changes during time in service, is reflected by two different indicators: the physical condition state and the functionality state. The physical condition state relates to a ... |

| ABSTRACT: Declining populations of the gopher tortoise (Gopherus polyphemus) have prompted management efforts including methods to increase egg clutch survival. Estimates are that as many as 88 percent of all clutches are being destroyed by predation. The most popular protection method has been to locate the clutch and protect it from predation with a metal cage or hardware screen. Locating the clutch without damaging or extensively disturbing the eggs requires ... |

|
| Dredging and disposal of dredged material in aquatic environments can expose animals and plants to episodic pulses of suspended sediment. Resuspended material can be deposited in thin layers adjacent to the dredging or disposal areas in some cases as much as several thousand meters distant (LaSalle et al. 1991). While our understanding of the potential effects of such far-field deposition is limited, some estuarine organisms may be highly sensitive to ... |
