Preliminary Modeling of Pesticide Fate in Drainage Channels Using the RIVWQ Model
نویسنده
چکیده
Contamination of drainage channels and creeks with pesticides used in agriculture is of major concern in south eastern Australia. In this study the stream pesticide model RIVWQ version 2.02 was assessed for its applicability to simulate pesticide fate in drainage channels. The model was successfully calibrated against field data collected on flows and pesticide concentrations for a drainage channel from a small catchment of five farms in the Murrumbidgee Irrigation Area of south western New South Wales. Using the calibrated model the effects of different pesticide loading scenarios from farm fields on channel water quality were analysed.

One of the problems of existing irrigation networks is seepage phenomena. Seepage problem and its control in irrigation channels is one of the most important issues in the design, construction, maintenance and operation of these channels. In this study, simulated the rate of seepage and phreatic lines in the Mianab irrigation and drainage channels located in the Karun basin using mathematical t...
متن کاملImproved Estimates of Kinematic Wave Parameters for Circular Channels
The momentum equation in the kinematic wave model is a power-law equation with two parameters. These parameters, which relate the discharge to the flow area, are commonly derived using Manning’s equation. In general, the values of these parameters depend on the flow depth except for some special cross sections. In this paper, improved estimates of the kinematic wave parameters for circular chan...

Rainfall-runoff from urban areas is one of the available water resources, which is wasted due to lack of attention and proper management. Besides, urban runoff excess of drains capacity causing many problems including inundation and urban environmental pollution. Therefore, harvesting this runoff can provide a part of the required water in urban areas, and also reduce flood and urban inund...
