Cylch 2 Cyrff Dŵr Daear y Gyfarwyddeb Fframwaith Dŵr (WFD)
Mae cyrff dŵr daear Cylch 2 y Gyfarwyddeb Fframwaith Dŵr (2014-2019) yn set ddata ofodol (polygon) sydd wedi'i chreu ar gyfer gweithredu'r Gyfarwyddeb Fframwaith Dŵr. Mae Erthygl 2, Cymal 2 y Gyfarwyddeb Fframwaith Dŵr yn eu diffinio fel '…yr holl ddŵr sydd o dan wyneb y ddaear yn y parth trwytho ac mewn cyswllt uniongyrchol â'r tir neu'r isbridd'. At ddibenion hysbysu o dan y Gyfarwyddeb Fframwaith Dŵr, mae corff dŵr daear yn cynrychioli corff penodol o lif dŵr daear gydag uned lifo gydlynol, gan gynnwys ardaloedd adlwytho a rhyddhau, gydag ond ychydig o lif ar draws y terfynau. Mae'r rhain yn adlewyrchu nodweddion hydroddaearegol sy'n ystyried gwybodaeth am nodweddion llif a cham, adlwytho, a pha mor agored ydynt i lygredd. Mae hyn wedi cael ei gyflawni drwy ddiffinio dyfrhaenau fel teipiau gwahanol a'u rhannu'n unedau dalgylch ar raddfa Strategaethau Rheoli Tynnu Dŵr Dalgylch.

The primary input dataset is '1:625K Classified Aquifer Geology'. This dataset has been digitised directly from the hard copy '1:250K Solid Geology Map' and classified according to aquifer type and are therefore directly derived from the underlying BGS data. These classifications were verified by the British Geology Survey (BGS).
These data have gone out for consultation at Area level and in some instances 1:50K Solid Geology has been used to define localised boundaries.
Since waterbodies are attributed with a unique identifier 'WB_ID' this dataset can be linked directly to other WFD data sources such as physical characteristics, risk, classification and proposed objectives.
