An Estimation Method for Used Water Quantity at Midnight to Detect Water Leakage

A simple flow-concentration modelling method for integrating water quality and water quantity in rivers

As part of the determination of the ecological Reserve for rivers in South Africa (National Water Act, 1998), flow requirements are assessed for maintenance low flow, drought low flow and flood conditions. Since water quantity and water quality are often closely linked, it is necessary to ensure that in setting the recommended flow regime, the appropriate water quality will be attained. This pa...

A Meta-model for Water Quantity and Water Quality

The management of water resources requires simulation models for different time horizons and spatial scales as well as different types of information systems as GIS or Water Information Systems. Mathematical models integrate former experiences and theoretical knowledge about a system with actual information gained by natural processes and man-induced activities. Because of the great variety and...

Water Quantity and Quality at the Urban–Rural Interface

Population growth and urban development dramatically alter natural watershed ecosystem structure and functions and stress water resources. We review studies on the impacts of urbanization on hydrologic and biogeochemical processes underlying stream water quantity and water quality issues, as well as water supply challenges in an urban environment. We conclude that converting forest lands to urb...

Using Bulk Water to Detect Ligand Binding

Measuring Water Droplets to Detect Atmospheric Icing

This thesis describes the exploration of amethod tomeasure the droplet size and the concentration of atmospheric liquid water. The purpose is to find a cost effective technique to detect the conditions for icing on structures. Icing caused by freezing atmospheric water can be a significant problem for infrastructure such as power lines, roads and air traffic. About one third of the global insta...
