Ascertaining the spatiotemporal accuracy of precipitation is a challenge for hydrologists and planners for flood protection measures. The objective of this study was to compare streamflow simulations using rain gauge and radar data from a watershed in Southern Ontario, Canada, using the Hydrologic Engineering Center’s event-based distributed Hydrol...

The focus of this study is to investigate the effects of climate change on the hydrologic regimes in Ontario, Canada. The variables include total precipitation, the form of precipitation (snowfall and rainfall), and the temperature during winter. The winter season is hydrologically significant for Canadian conditions. The historical data for 70 yea...

Freshwater resources are a natural blessing and vital to life. Water is required in many aspects of life due to its importance in the economy. A Floppy sprinkler system (FSS) is an innovative and unique method for pressurizing irrigation. This method has multiple applications other than traditional methods, which can overcome farmer's issues to ado...

Contrary to the constraints in time, investment, and management of the traditional technology for waste water treatment, this paper seeks to propose a more advanced, reliable, and affordable new technology to restore urban polluted rivers to pristine quality levels. The paper also presents new ideas on the selection and use of microbial agents to i...

Punjab, Pakistan is famous for rice production in all over the world, but economic indicators are low toward rice contribution in the regional economy. Climatic and physical factors are responsible for rice yield degradation. Suitable land for rice cultivation can be mapped keeping in view these climatic and physical factors. In this research, rice...

Utilization of potato as a processed food can help stabilize the potato production as well as its price. Processed food requires certain quality parameters for raw material. With an aim to improve quality parameters of potato, a field study was conducted using mulches and drip irrigation. Three different type of mulches (plastic, bio-de-gradable an...

Total cropped area of Pakistan is 27.48 million hectares which is 34.4 percent of total land area. Annual population growth rate of Pakistan is around 1.5 %. Current population of Pakistan is about 199 million and this makes Pakistan the 6th most populous country in the world. Rapid urbanization due to increasing population has reduced the cultivab...

A study was conducted to delineate baseflow dominated and rapid response flow dominated watersheds by evaluating six different baseflow separation methods: digital filter, PART, United Kingdom Institute of Hydrology (UKIH), local minima, base fixed and base sliding for one hundred and fifteen watersheds in Southern Ontario (Canada). The streamflow...

The proper design of a bioremediation strategy for petroleum-contaminated sites requires a reasonable estimate of the biodegradation rate constant, which is not easy due to spatial heterogeneity. Accordingly, predictive models were developed by completing a bioventing study at the meso-scale. Reactors holding 4 kg of disturbed soil were tested usin...

There is a general consensus that climate change has impact on the intensity and frequency of rainfall events. However, very little research is available about the changes in short term rainfall extremes. The focus of this paper has been on the change in annual and monthly rainfall extremes in Ontario. The results indicate a greater variability (in...

Cotton producing countries are seeking ways and means to boost their exports, essentially to strengthen their economics. Although Pakistan is playing a key role in world cotton trade and production yet facing challenges due to quality and high cost of ginning. One of the major problems faced by the ginning sector is old technology of cotton ginning...

Plastic mulches have various beneficial effects on crop production, including an increase in soil temperature, conservation of soil moisture, texture and fertility; and the control of weeds, pests and diseases. This technology is not only helping to alleviate the issue of climate change but also helping farmers to increase yield, thereby high econo...

Despite recent advancement in Agricultural Engineering, hunger and poverty is noticeable in the developing countries. Developing countries are facing several issues such as: high cost of farming, lake of resource conservation, and shocking environmental conditions. The objective of this article is to summarize typical problems faced by agricultural...

Bioventing can be effective for the remediation of soil contaminated with petroleum hydrocarbons. However, implementing laboratory results in field scenarios is difficult due to the lack of scale-up factors. Accordingly, laboratory bioventing experiments were undertaken at the meso-scale and then compared with previously completed micro-scale tests...

A mobile water spraying system using a rain gun was developed and tested in the citrus orchard of the University of Agriculture, Faisalabad. Guidelines were developed for researchers/farmers to make decisions with respect to the amount of water that should be sprayed for the temperature to be reduced to the desired level. Preliminary testing of the...

The technology to use agricultural wastes as an alternate source of energy is quite old. Direct burning and conversion of gaseous fuels from solid agricultural wastes are quite common. Agricultural wastes in Pakistan have the potential to produce over 3 million tones of oil equivalent (tOE) which account for about 10% of the total energy demand in...
