    IMPROVING IRRIGATION WATER MANAGEMENT IN THE INDUS BASIN (1979)

    Notes: : Over half of the water delivered from the canal system to the watercourses managed by the farmers is not made available to the farmers' crops in Pakistan. Most of this water loss is due to loss of water through the banks of the watercourses. Lack of maintaining these banks and lack of cleaning the watercourse is a result of inadequate organization of the 10 to 150 farmers who use the watercourse, and a deficiency of knowledge concerning the amount of their water which is being lost.Various methods of watercourse improvement have been evaluated including concrete and masonry linings and simple earthen improvements of the ditches with concrete control structures, junctions, and turnouts. With the cost of labor low in Pakistan, the earthen improvements with concrete structures appear to be the best investment.Farm water management improvement programs have been implemented in most of the provinces which include this type of watercourse improvement, land leveling and advice to the farmers on how and when to irrigate his crops to optimize his production.The rate at which personnel can be trained to help the farmers implement these improved water management practices is limiting the rate of implementation.

    Beitrag zur Beurteilung der Keuchhustentherapie (1937)

    Notes: Zusammenfassung An 100 mit Petein (49%), Lumivol (33%) und Na- bzw. KBr. (18%) behandelten Kindern mit einem Durchschnittsalter von 1 Jahr 8 Monaten wird die Verlaufskurve des Keuchhustens errechnet und mit der von B. und M. angegebenen Normalverlaufskurve des unbehandelten Keuchhustens verglichen. Die Kurve bestätigt die klinisch im Gegensatz zur Beobachtung außerhalb des Krankenhauses gemachte Erfahrung, daß diese Behandlungsarten wirkungslos sind. Dabei muß betont werden, daß das Petein erst im Stadium convulsivum gespritzt wurde und unsere Versuchsergebnisse nichts gegen seine Wirkung im Stadium catarrhale sagen. Auf die Unempfindlichkeit des Hustenzentrums beim Keuchhusten gegen die längere Zeit gegebenen Sedativa Lumivol sowie Na- bzw. KBr wird hingewiesen. Die Kurve wird für die eigene Klinik als Grundlage zur Beurteilung weiterer Heilversuche am Keuchhusten benutzt werden können.

    Effect of drying on soil strength and corn emergence (1985)
    Springer
    Irrigation science 6 (1985), S. 149-158 
    Details
    ISSN: 1432-1319

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Laboratory studies were conducted to evaluate the effects of drying on soil strength and corn emergence (Zea mays L.). Corn was germinated in Billings silty clay under a bank of heat lamps which operated 9, 14, 19, or 24 h per day. Soil strength (modules of rupture), soil moisture content and emergence were measured daily. The relationship of soil strength to corn seedling emergence as influenced by the four light and heat durations and bare and mulched soil surfaces was determined. As soil strength increased emergence decreased until it ceased at soil strengths of about 80 kPa. Strength of this soil had a high negative correlation with soil water content and increased with time. Mulching decreased initial rate of drying, decreased crust strength, and improved corn emergence. The 14-hour light and heat treatment resulted in the highest corn emergence.

    Surface films affecting velocity profiles of slowly moving water in open channels (1984)
    Springer
    Irrigation science 5 (1984), S. 235-250 
    Details
    ISSN: 1432-1319
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Rates of movement of surface films and underlying water were measured using observable solid and liquid tracers. Water flow rate, surface width, water depth, and channel length were varied in flumes in which the water was allowed to flow over a broad weir crest at the tail end. In some runs the surface was blocked 5 cm in front of the weir. When this was done, velocity of the surface film immediately upstream from the block decreased to a small fraction of its previous value and this area of slow surface velocity built upstream with time, extending to as far as several meters under steady state conditions. In this reach, the film at the air-water interface of the water causes drag on the moving water similar to that at a solid-water interface. Water surface in channels one cm wide and 100 cm long stopped moving when the shear force caused by water flowing beneath it dropped to less than 0.0013 dynes/cm2. This indicates structure in the surface which does not deform or shear at rates proportional to the force applied. Average water flow velocities from 0.3 to 1 cm per second provided shear stresses in excess of 0.002 dynes/cm2 and moved these surface films. However, the velocity distribution across the surface of the channel was not parabolic, and indicated that most of the shear in the film was taking place near the edges of the channel. Extrapolation of these observations to water film dimensions present in unsaturated soils indicates that air-water interfaces in unsaturated soils are usually static.

    Sediment, erosion and water intake in furrows (1988)
    Springer
    Irrigation science 9 (1988), S. 45-55

    Notes: Summary Observations and studies were conducted on the origin and destination of sediment in irrigation water, and the effects of sediment adsorbed on the wetted perimeter of furrows on water intake and erosion. Fine sediment adsorbed on the perimeter reduced intake and increased soil water tension which was the primary mechanism holding the sediment on the perimeter. This self enhancing effect causes this thin seal to decrease erosion and intake rates. In contrast, removal of a few square centimeters of this seal by chance events after water velocities and shear forces have increased often causes reduced tensions, exfoliation of the surface seal and erosion pits which develop into head cuts.
