Abstract: A one‐dimensional Lagrangian transport model that alleviates the numerical difficulties associated with the use of an Eulerian reference frame by simulating convection with a parcel‐tracking algorithm is presented. The ...

Abstract: A two‐dimensional laterally averaged model for suspended sediment transport in steady gradually varied flow that is based on the Lagrangian reference frame is presented. The layered Lagrangian transport model (LLTM) for ...

Abstract: From a global perspective, the annual average surface temperature in 2004 was the fourth highest value observed since regular instrumental records began in 1880. Global surface air temperatures in 2004 were 0.44°C (0.79°F) ...

Abstract: Horizontal wind speed and direction range data range obtained during 300 hours of westerly winds on both the east and west shores of the Chesapeake Bay during the period December 1960 through May 1961. Measurements of air ...

Abstract: Tall tower wind data are used to illustrate some of the features of low turbulence (smooth) flow aloft. Information is presented on spatial and temporal variations of such flows. The relevance of low turbulence flow to ...

Abstract: The significance of accurate antenna position determinations is presented. Various error sources that affect the precision of the position of the antenna phase center relative to the station mark are also presented. Field ...

Abstract: A kinematic GPS (Global Positioning System) survey was performed by the National Geodetic Survey to determine the feasibility of using the method operationally on some geodetic surveying projects. The method of the experiment ...

Abstract: The basic shift in intergovernmental relationships that has occurred since 1975 has important implications for the achievement of social and environmental goals that guide the management of water resources. These changes, ...
