Web-based SCIMAP | SCIMAP – Diffuse Pollution Risk Mapping

This site uses cookies to improve your experience. You can download the pdf of the poster here. On this web-site, we provide a basic description of the science base that we are developing, we illustrate the SCIMAP approach and how it works, and we provide material for further learning about the approach. Not all fields will be polluting.

SCIMAP diffuse pollution risk mapping and EdenDTC

By combining the risk of pollution generation and the risk of connection we can determine the risk that pollution gets into the water environment. If a down slope point is not also saturated, the upslope risk will be captured at this point and not reach the river channel, the cell is disconnected.

This project was originally jointly developed between Durham and Lancaster Universities. This site uses cookies. Traditionally, we accepted that water can become polluted because we discharge waste into it. If we want, we can dilute the accumulated risk by the uplsope contributing runoff to get a risk concentration.

The strength of the connectivity between two points in the landscape depends on many factors both regarding the nature of the landscape and the substance of interest, e. Most models that seek to characterise the delivery of diffuse pollutants from land to water are reductionist.

If runoff is generated further sckmap and flows into the river channel, then this lower part of the slope will be connected whereas the upper part of the slope will not be connected.

What do we now know? This type of waste comes from a large number of scimp e. It becomes a problem because it gets funnelled into our rivers where the concentrations can be very high.

The SCIMAP risk mapping framework has sfimap a distributed treatment of surface hydrological connectivity based on the analysis of the potential pattern of soil moisture and saturation within the landscape. Use the form below to search the site: The concept of connectivity is increasingly being applied in hydrology as researchers attempt to move beyond the traditional partial or variable source area models for runoff generation and consequent material transport to recognize that the flux of water and the materials it […].

The above animation shows the how hydrological connectivity develops along a hillslope.

This diffuse pollution risk is then routed through the landscape and diluted according to the amount of water that would flow through the point. Whitman, Rachel Pain, and David G.
