Гидроморфологические исследования малых рек суб-бассейна дельты Дуная: оценка экологических нагрузок и рисков

ENVSEC Danube Delta II Project

Общая цель Рамочной Директивы по воде это установление охранного режима для внутренних поверхностных, межграничных, морских, прибрежных и грунтовых вод

Природоохранная цель - достижение «хорошего статуса»для всех поверхностных и грунтовых вод, самое позднее 2015 году.

Data collection templates

Typology and water bodies

Danube: 2 types (B), 5 water bodies (WB)

Rivers (catchment > 500 km2): 6 types (A) in MD and UA, 33 WBs 1 type (B) in RO, 2 WBs

Lakes (surface > 10 km2): 7 types (A) 23 WBs

Transitional: fluvial, 3 WBs lacustrine, 1 WB marine, 2 WBs

Coastal: 1 type, 2 WBs

Total: 71 water bodies

Rivers (33 WBs):

only 15 % without pressure

Lakes (9 WBs):

All lakes: artificial water supply7 lakes: regulated shore 1 lake: closed from sea

Hydromorphological pressures

Heavily modified and artificial water bodies

Based on RO RBMP (2009) and special methodology for UA and MD WBs. Danube: HMWB and possibly HMWB, except Sf Gheorghe arm 1 artificial canal (Sulina - Sf.Gheorghe)

Transitional fluvial: Bystroe canal, due to regulation for navigation

Small rivers: 22 HMWB, 6 are possibly, 1 artificial

Lakes: in RO: out of 14, 1 is HMWBin UA: all 9 WBs are HMWB or possibly HMWB

Conclusions about status and risk of failing good status/potential

For Romanian WBs, ecological status (2009):

Exept Razim lake, all WBs are not in good status

For UA and MD WBs, risk evaluation based on HM pressures and pollution loads.

Pollution only: 3 WB Hydromorphology only : 17 WBs Both problems: 25 WBs 2 transitional fluvial WB is not at risk
