Because river slope generally decreases in a downstream direction, it is generally supposed that velocity of flow also decreases downstream. Analysis of some of the large number of velocity measurements made at stream-gaging stations demonstrates that mean velocity generally tends to increase downstream. Although there are many reaches in nearly all rivers where mean velocity decreases downstre...

Rich D animated explanations can have a pow erful impact on students interacting with im mersive knowledge based learning environments By generating D animated explanations in re altime a learning environment can create en gaging explanations that are tailored to individ ual students This paper presents the immersive explanation planning framework for generating pedagogically customized D anima...

Surface textures of high resolution and quality, either acquired from aerial or satellite imagery or computed using procedural models, are crucial for photorealistic terrain rendering. Procedural models provide a compact representation and can be evaluated at run-time. In this paper we present an extension to an existing, GPU-friendly procedural texturing model, such that it can be fitted semia...

CASC2D is a physically-based, distributed model that simulates the response of a watershed to precipitation. Basic processes in the model include: precipitation, interception, infiltration, surface runoff and channel flow, and erosion and deposition of upland soil and channel bed sediment. Model performance is demonstrated by applications to numerous sites such as Goodwin Creek, MS. This waters...

This study presents an innovative concept acoustic metrology for on-line dimensional conformance inspection. It investigates the linear and radial dimensions as well as the true position of a center. It conclusively finds that as these dimensions change, the resonant frequencies of tested cylindrical and flat plate parts also shift. The high resonant frequencies appear to shift more than low re...

Droughts are natural disasters with a significant impact on the economy and social life. Prolonged droughts can cause even more damage than floods. The novelty of this work lies in definition synthetic drought hydrograph (SDH) which be derived at each gaging station river network. Based hydrographs (DHs) recorded for selected station, SDH is statistically characterized provides valuable informa...

Stage and discharge are some of the oldest measurements in environmental fluid mechanics vital forecasting water supply flood safety. These traditionally manpower intensive, hence expensive, dangerous under high flow conditions. Considering climate change planet’s increasing population there is a critical need for better, more accurate, frequent, space time, data model forecast guidance. This s...
