Volume-Based Runoff Coefficients for Urban Catchments
(American Society of Civil Engineers, 2014)The rational method is derived as a special case of kinematic wave flow. The definition of runoff coefficient is expanded from the peak-based to volume-based ratio between runoff hydrograph and rainfall hyetograph. The new ... -
Factorial Study of Rain Garden Design for Nitrogen Removal
(American Society of Civil Engineers, 2014)Nitrate ( -
Water Discharge Measurement in Agricultural Catchments Using Critical Depth Flumes Affected by Sediment Deposition
(American Society of Civil Engineers, 2014)Flumes and weirs are hydraulic structures used to measure soil erosion and runoff at the outlet of agricultural catchments. Long-throated flumes use critical flow theory to determine discharge from a single water depth ... -
Reservoir Water Allocation under Abrupt Pollution Condition
(American Society of Civil Engineers, 2014)A suitable strategy for analyzing a water-resource system reaction to abrupt pollutants and for examining the necessity and the nature of management programs would necessitate quality-quantity modeling of the system and ... -
Water Requirement with Irrigation Expansion in Jingtai Irrigation District, Northwest China: The Need to Consider Irrigation-Induced Local Changes in Evapotranspiration Demand
(American Society of Civil Engineers, 2014)Because water diverted from the Yellow River has been used for irrigation in 1972, obvious changes in evapotranspiration demand (denoted by reference evapotranspiration) have been observed in the Jingtai Irrigation District, ... -
Effects of Runoff Characteristics and Filter Type on Geotextile Storm Water Treatment
(American Society of Civil Engineers, 2014)Urban storm water runoff carries particulate matter and other pollutants to water bodies, causing environmental problems. Removing suspended solids from runoff through geotextile filtration is a storm water control measure ... -
What Should Be the 95th Percentile Rainfall Event Depths?
(American Society of Civil Engineers, 2014)Based on Section 438 of the Energy Independence and Security Act of 2007, the U.S. Environmental Protection Agency (USEPA) published a report providing technical guidance that recommends using the 95th percentile rainfall ... -
Storm-Water Bioinfiltration as No-Irrigation Landscaping Alternative in Semiarid Climates
(American Society of Civil Engineers, 2014)In semiarid cold desert climates, bioinfiltration gardens as green infrastructure storm-water management facilities show promise to serve as both on-site storm-water management and no-irrigation landscaping. Both services ... -
Assessment of Climate Change Impacts on Reference Evapotranspiration and Simulation of Daily Weather Data Using <i>SIMETAW</i>
(American Society of Civil Engineers, 2014)In this study, a -
New Stage-Discharge Relationship for Weirs of Finite Crest Length
(American Society of Civil Engineers, 2014)The flow process of weirs of finite crest length is analyzed on the basis of the dimensional analysis and incomplete self-similarity theory. The crest length is incorporated in the functional stage-discharge relationship ... -
Optimal Water Allocation in Shortage Situations as Applied to an Irrigation Community
(American Society of Civil Engineers, 2014)This work studies the most beneficial way of allocating water in an irrigation community in water shortage situations. Therefore, it proposes that the irrigation surface area be divided into homogeneous zones, each with a ... -
Drainage-Process Analyses for Agricultural Non-Point-Source Pollution from Irrigated Paddy Systems
(American Society of Civil Engineers, 2014)The aim of this study was to investigate the effects of drainage processes on non-point-source pollution in a complex irrigation and drainage system. Field experiments were conducted to measure quality and quantity of ... -
Mixed Flows with Depressurizing Wavefront in Circular Pipe
(American Society of Civil Engineers, 2014)Rapid pipe filling or emptying of water mains and sewer systems is accompanied by transitions between free surface and pressurized flow regimes and subatmospheric unsteady flows, leading to the propagation of pressurized ... -
Saving Water in Chufa Cultivation by Using Flat Raised Beds and Drip Irrigation
(American Society of Civil Engineers, 2014)Chufa, also known as tigernut, is a typical crop in Valencia, Spain, where it is cultivated in ridges with furrow irrigation. This paper examines the effects of the planting strategy (PS) and irrigation system (IS) on yield ... -
Depth-Averaged Specific Energy in Open-Channel Flow and Analytical Solution for Critical Irrotational Flow over Weirs
(American Society of Civil Engineers, 2014)Free surface flow in open-channel transitions is characterized by distributions of velocity and pressure that deviate from uniform and hydrostatic conditions, respectively. Under such circumstances the widely used expressions ... -
Evaluation of Nonlinear Root Uptake Model for Uniform Root Zone vis-à-vis Multilayer Root Zone
(American Society of Civil Engineers, 2014)Water movement in the soil–root system is an important component in modeling of the hydrological processes. A nonlinear root uptake model was developed and validated for a nonuniform crop root zone in a semiarid agro-climate. ... -
Estimation and Analysis of Irrigation in Single-Family Homes in Central Florida
(American Society of Civil Engineers, 2014)There are several studies that have estimated how much water is used for residential irrigation, principally at the national level, with outputs varying from 30 to 64% of total household potable water use. A methodology ... -
