2. Inside of the drainage groove is heated with heating means, such as gas burner. 3. Waterproof primer is applied to a circumference side wall surface and a bottom part of the drainage groove with application means, such as brush. 4. Asphalt containing molten filler 5 having a large ...
6638 RESEARCH ON SURFACEWATER DRAINAGE by Leonard Henry Watkins, B.%. Principal Scientific Officer, Road Research Laboratory, Department of Scientific Industrial Research For discussion at an Ordinary Meeting on Tuesday, 2 April, 1963, at 5.30p.m., and for subsequent written discussion. and ...
This book chapter discusses the health implications of inadequate surface water drainage urban planning implications and the need for collaboration between sectors. A typical drainage improvement program must pass through four principal phases: initiation planning construction and maintenance. Initiation and pl...
An experiment was conducted to quantify the weed dynamics, root growth, relative water content and leaf rolling on transplanted rice with the imposed surface drainage under controlled irrigated conditions. The maximum grain yield (3407 kg/ha) was obtained on continuous flooding followed by surface dra...
Drainage areas for about 1,500 surface-water sites on streams and lakes in Florida are contained in this report. Sites are described in relation to a nearby city or town, and are located by county, by latitude-longitude, and by topographic map on which it is located. In addition, the su...
Inadequate drainage outlet causing surface waterlogging every year mainly during monsoon period (June through October) over a depressed land of 1062 km2 in
Ivy Groundwater Assessment and Mapping When housing is developed in rural areas without the extension of public infrastructure for water and sewage, these developments must draw on groundwater, ... MN French,PD Hillegass,M Tan - Systems & Information Engineering Design Symposium 被引量: 2发表: ...
Drainage networks are extracted from the US Geological Survey 1/3 arc-second 3D Elevation Program elevation data having a nominal cell size of 10聽m. This research demonstrates the utility of open source tools with parallel computing support for extracting connected drainage network patterns and ...
Although most of the nutrient outflow was attributed to plant uptake, nutrient loss by surface drainage was substantial. The simplified computer model, PADDIMOD, was developed to simulate water and nutrient behaviors in the paddy rice field. The model predicts daily ponded water depth, surface ...
The unconventional natural gas industry emerged as a new water user in the Susquehanna River Basin in the northeast United States in 2008. Through 2013, a total of 2860 gas wells were hydraulically fractured, with each fracturing event consuming an average of 4.3 million gallons of water. The ...
