Abstract:

3 pp.<br>Critical to any irrigation management approach is an accurate estimate of the amount of water applied to a field. Too little water causes unnecessary water stress and can result in yield reductions. Too much water can cause water logging, leaching, and may also result in loss of yield. This publication discusses how to set the water amount and the time period, when taking the system's efficiency into consideration.

Abstract:

The amount of time cattle spend standing in streams is one input parameter needed by computer models when total maximum daily load (TMDL) plans are being developed. This input parameter is estimated using professionals' best judgment because experimental data are not available, and estimations are generally inconsistent. The goal of this study was to gain a better estimate of the amount of time cows spend in streams, since this has a significant impact on direct fecal coliform loadings to streams. Significant factors influencing the amount of time cattle spend in streams were identified, an

Abstract:

8 pp.<br>Irrigation water is a major input into production of a forage crop. The purpose of this research is to compare the yield and quality of forage sorghum grown with differing amounts of irrigation water. A linear move sprinkler system was used to apply 11 water application amounts from 23.79 to 35.52 inches over the season. Forage yield peaked at a water application amount of around 32.60 inches according to a quadratic function of yield vs water applied. Increasing irrigation amount decreased forage quality by increasing fiber components. Profit was maximized at 30.20 to 32.60 inches of

Abstract:

Rapid and deep transport of solutes in soils can potentially pollute groundwater resources. Field estimates of solute leaching depth based on randomized sampling provide extremely variable field average estimates that confound the treatment effects of the leaching study with the high spatial variation of soil hydraulic properties. The purpose of this study was to investigate the spatial scale of variation of solute (Bromide) leaching depth, and apply this scale of variation to study the leaching depth of Bromide as a function of a sinusoidal application of transport causing factors, i.e., rain

During the late 1970s, when oil exploration and extraction from the North Sea were at a peak, there was increasing concern about the number of episodes of unexplained confusion, loss of consciousness and deaths during dives.

The model integrates water rights allocation, efficient water allocation and equitable income distribution subject to hydrologic constraints comprising both water quantity and quality considerations.

It is an essential requirement when test separators or the newly developed full multiphase meters are utilized for oil well production testing. Water-cut can be obtained from measurement of differential pressure, capacitance/conductance, gamma rays absorption, absorption of infrared light, coriolis mass measurement, or microwave permittivity. The use of microwave permittivity has been shown to be ve

Previous studies have suggested that the import of virtual water, defined as the volume of water required to produce a commodity or service, can relieve pressure on a region's water resources. This study seeks to quantify virtual water flows among U.S. states using the water footprint and input-output analytical methods, and to compare the quantitative results to actual water use volumes in agriculture.

This dissertation investigated the estimation of global cloud water amounts. The study was prompted by the large discrepancy in published global mean values of cloud liquid water path. Microwave and optical satellite measurements of this quantity range from 25 g/m² to 80 g/m². Theoretical estimates are significantly larger with a current best guess value of 380 g/m². The major limitations of microwave measurements were found to be the inadequate separation of the cloud- and rainwater components, and the lack of retrievals over land.

Abstract:

Peatlands store 30% of global terrestrial organic carbon. At the Mer Bleue research site in southern Canada (45.40° N, 75.50° W), it has been shown that changes in water storage affect carbon fluxes in and out of the peatland. Mer Bleue has a distinct hummock – hollow surface topography. The micro-topographical features affect the temporal and spatial variations in water table. Sampling the temporal and spatial variations on two separate plots with varying degrees of micro-topographic relief took place during the 2010 field season. Each plot has 100 manual observation wells in a 2 x 2 metre gr

Abstract:

Measurements of runoff quantity and quality from three cattle stocking treatments applied to pastureland in southwestern Virginia indicate the need for further research to determine treatment effects. Three cattle stocking treatments (1) Continuous, 2) Rotational, and 3) Mob) were applied to three pastures at the Virginia Tech Prices Fork Research Farm. Rainfall simulations were performed over replicated plots in each treatment to induce runoff for collection of runoff quantity and quality data during the 2012 grazing season. Additionally, rainfall simulations were performed prior to applying

Abstract:

Dans le contexte péri-urbain à dominance agricole de l’Ile de France, les pressions anthropiques exercées sur les rivières jouent autant sur la qualité que sur le débit des cours d'eau. Située au sud-ouest de Paris, l’Yvette draine un bassin versant de 202 km²et à la géologie homogène. Elle est alimentée directement par des stations d'épuration (STEP) et par la nappe des sables de Fontainebleau qui représente la principale source d’eau. Sur ce type de bassin, la gestion durable du système riverain repose sur la connaissance de la distribution des flux nappe – rivière et sur l’impact de cette r
