Performance of Buried Small Pipes
(American Society of Civil Engineers, 1988)An analytical and experimental program was conducted to study the deflection and load‐carrying capacity of small‐diameter corrugated plastic drain pipes. The pipe samples were buried in different soils with various compaction ... -
Water Flow in Layered Soils With Sloping Surface
(American Society of Civil Engineers, 1988)An analytical solution is derived for a two‐dimensional soil with a sloping surface under steady and water‐saturated flow conditions. The soil was assumed to consist of several layers, each horizontally stratified. The ... -
Evaluating Peat‐Mining Hydrology Using Drainmod
(American Society of Civil Engineers, 1988)A process that uses the field‐scale model DRAINMOD to simulate the hydrologic response of a watershed to peat mining is presented. An eastern North Carolina watershed has been proposed as the site of a peat mining project. ... -
Improving Canal Water Deliveries with Auxiliary Storage
(American Society of Civil Engineers, 1988)The temporal distribution of an irrigation water delivery and demand ratio was used to analyze the performance of an irrigation water delivery system in the Bhakra Canal Command in India. A high degree of mismatch was found ... -
Water Management for Lowland Rice Irrigation
(American Society of Civil Engineers, 1988)A procedure has been developed to increase irrigation efficiency by estimating probabilistic irrigation requirements for lowland rice cultivation. The procedure uses a water balance equation with random components to ... -
Mobile Flume for Circular Channel
(American Society of Civil Engineers, 1988)A simple device to measure discharge in sewers and drainage channels is described. The unit can be quickly fixed and removed for short‐time use in circular channels. Its major advantages include low cost, reading precision, ... -
Satellite Data and Geographic Information System for Land Use Classification
(American Society of Civil Engineers, 1988)Landsat Multispectral Scanner System (MSS) data in conjunction with the unsupervised classification technique of Earth Resources Laboratory Application Software (ELAS) were used to determine land use/land cover classifications. ... -
Annual Flow Statistics for Ungaged Streams in Idaho
(American Society of Civil Engineers, 1988)Annual streamflow records for 124 stream gages in and near Idaho are examined to determine four annual flow statistics: the mean; the standard deviation; the skew coefficient; and first‐order serial correlation coefficient. ... -

Simple Method of Obtaining Su‐Brooks Retention Parameters
(American Society of Civil Engineers, 1988)The Su-Brooks retention function was linearized by transforming the functon into logarithmic form. The resulting equation had a form that allows determination of the parameters using linear multiple regression techniques. ... -

Subsurface Drainage Peak Flows in Shallow Soil
(American Society of Civil Engineers, 1988)The subsurface drainage operation of shallow soils is characterized by sudden and brief peak flows followed by long‐lasting tail recessions. A field experiment was conducted on a seasonally waterlogged, shallow loamy soil ... -
Using Center Pivots for Research
(American Society of Civil Engineers, 1988)Research to determine crop water-production functions normally involves random block designs or a line sprinkler source. Both of these setups have disadvantages that can largely be overcome by using modified center pivots. ... -
Redevelopment of Clogged Recharge Wells
(American Society of Civil Engineers, 1988)Field conditions were reproduced in the laboratory in order to investigate redevelopment techniques. Segmental perspex models were recharged with water of controlled quality and temperature containing different types of ... -
