/env (online) - European countries have defined more than national river types and more than national lake types, to implement the EU Water Framework Directive. In addition, common river and lake types have been defined within regions of Europe for intercalibration of the national classification systems for ecological status of water bodies.

This new broad typology reflects the natural variability in the most commonly used environmental type descriptors: altitude, size and geology, as well as mean depth for lakes. These broad types capture % of all national WFD types including almost 80% of all European river and lake water bodies in almost all EU countries and can also be.   The typology is aimed at defining the type-specific reference conditions against which the ecological state of waters can be assessed. The abiotic typology of Polish lakes of an area greater than 50 ha was established based on morphometric, hydrographic and physico-chemical data taken from the Polish national monitoring dataset.   Lakes A lake is a body of water of considerable size, localized in a basin, that is surrounded by land apart from a river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds. Natural lakes are generally found in mountainous areas, rift zones, and areas with. As background for the recommendations we first give an overview of the main water use categories in Myanmar. We then provide preliminary suggestions for typology criteria and indices for assessing ecological status in lakes and rivers in Myanmar. The typology factors and physico-chemical parameters are based on common used factors in the EU.

Rivers and Lakes – Typology, Reference Conditions and Classification Systems • How can ecological criteria and pressure criteria be used in site selection and for setting class boundaries? • What benchmark should we use to determine very minor and slight disturbance in terms of pressure criteria?
