Environmental Monitoring & Modelling

Heat stress, air quality and dispersion before you set out.

Live weather and air quality for the site turned into field guidance: WBGT heat stress, atmospheric stability, a Gaussian plume model for a nearby source, a weighted water-quality index with concrete sulfate class, and the MEDALUS desertification index.

Overview

Each indicator has a short academic note: what the value means for field safety, for instruments, and for materials on site. A Gaussian plume model predicts where emissions from a point source will travel under the current wind.

Laboratory results for soil and water can be entered to receive a geological interpretation in the same report.

Method and equations

Gaussian plume

Ground-level concentration with reflection; Pasquill–Gifford class from wind and insolation; Briggs (1973) rural dispersion.

C = Q / (π u σy σz) · e−y²/2σy² · e−H²/2σz²

Water quality index

Weighted arithmetic index against WHO drinking-water guidelines.

WQI = Σ qi Wi / Σ Wi,   Wi ∝ 1/Si

MEDALUS

Geometric mean of soil, climate, vegetation and management quality.

ESAI = (SQI · CQI · VQI · MQI)¼
