Effects of hysteresis with air entrapment on water content and head distributions, surface fluxes, and water balance components are investigated by finite element simulations of flow in one- and two-dimensional spatial domains. Results of...

Accurate flow measurement is essential for the management of any type of fluid system. This research investigated the effect on accuracy that five types of 12-in. differential-pressure flow meters have as a result of being installed in pipelines...

Energy losses occurring in pipe junctions have been studied for many years. Head loss coefficients (KK) are commonly used to characterize losses across elbows, tees, crosses, valves, and other pipe fittings. When accurate values of KK are used,...

Water utility managers generally agree that water meters, especially mechanical water meters, experience a degradation of accuracy over time. This degradation is a function of several factors, such as wear, water quality, water velocities,...

Parshall flume tests were conducted to determine the sensitivity on indicated flow rate resulting from improperly located staff gauges and differing entrance conditions to the flume. An acrylic 2 ft (61 cm) Parshall flume was constructed to...

Rural coastal aquifers are undergoing rapid changes due to increasing population, high water demand with expanding agricultural and domestic uses, and seawater intrusion due to unmanaged water pumping. The combined impact of these activities is...

With the exception of our neighbor to the west, Nevada, Utah receives less annual average precipitation (approximately 13 inches) than any of the other 50 States. The average rainfall for the United States is approximately 30 inches per year. As a...

The types of data and models used within the hydrologic science community are diverse. New repositories have succeeded in making data and models more accessible, but are, in most cases, limited to particular types or classes of data or models and...

The 26 December 2004 tsunami caused widespread destruction and contamination of coastal aquifers across southern Asia. Seawater filled domestic open dug wells and also entered the aquifers via direct infiltration during the first flooding waves...

This paper presents a modeling approach based on a geographic information system (GIS) to estimate the variability of on-ground nitrogen loading and the corresponding nitrate leaching to ground water. The methodology integrates all point and...
