Natural landscapes and built environments can be engineered to optimise the goods and services delivered to society, including provision of natural resources and the regulation of water and carbon. Technologies that prevent and/or reverse land degradation can be devised and implemented to ensure sustainable use of finite land resources. Environmental engineers and land managers need sound understanding of the environmental properties that determine land capability for any given desired end use, as well as the interrelationships between soil, water, vegetation and built structures. This understanding is grounded in basic soil physics, hydrology, hydraulics, geotechnics and agronomy. With this background, appropriate interventions such as soil erosion control and slope stabilisation can be designed and implemented to improve inherent land quality.

Water of good quality is necessary for domestic, environmental, industrial, recreational and agricultural applications. As a result of the conditions prevailing in the catchment area, natural and anthropogenic constituents in water bodies will define potential uses according to established criteria. Hence, for those working in water science, a comprehensive understanding of regulations applicable to water quality is needed. This module provides an overview of Water Framework Directive and other relevant water quality regulations and policies that govern the management and assessment of surface waters. If quality is to be adequately monitored, it is also important to acquire knowledge about sampling and measurement of water parameters and interpretation of acquired data. It also provides background in ecological processes, aquatic communities, and survey design and data analysis to help those working in environmental water management to interpret water quality data in the context of the catchment characteristics and pressures.
