Development and testing of the HYPE (Hydrological Predictions for the Environment) water quality model for different spatial scales
The HYPE model is a hydrological model for small-scale and large-scale assessments of water resources and water quality, developed at the Swedish Meteorological and Hydrological Institute during 2005–2007. In the model, the landscape is divided into classes according to soil type, land use and altitude. In agricultural lands the soil is divided into three layers, each with individual computations ...

An adaptive framework to differentiate receiving water quality impacts on a multi-scale level
The paradigm shift in recent years towards sustainable and coherent water resources management on a river basin scale has changed the subject of investigations to a multi-scale problem representing a great challenge for all actors participating in the management process. In this regard, planning engineers often face an inherent conflict to provide reliable decision support for complex questions ...

Quarry dewatering compliance - Case Study
Louis W. Bray Construction installed a Greyline Area-Velocity Flow Meter in 2009 to meet Ministry of Environment regulations. Their permit stipulated effluent limits plus monitoring, sampling and flow measurement of wastewater discharged from the site to the South Raisin river. The Ontario Water Resources Act requires flow monitoring for any quarry dewatering greater than 50,000 liters per day. ...

Assessment of the impact of water parameters on the flow rate of ceramic pot filters in a long-term experiment
Poor water quality is a major contributing factor to disease in developing countries. Silver-coated ceramic pot filters (CPFs) are a relatively common form of household water treatment system (HWTS) representing an effective and sustainable technology for poor communities. Water production seems to be the major limiting factor of the CPF's lifetime and sustainability since low flow rates do ...
