The sustainable water management is a process based on a brief knowledge about the water resources availability. The water lack or excess in the form of droughts or flooding, and/or improper water use can cause serious disruptions in the water management process with negative effects on the water supply, economy, and the human and ecosystems well-being. To minimize the negative consequences a specialized research is needed. It requires a complex study that allows objectively detecting of critical aspects in the wa...

Flood occurrences outline the Bulgarian Skat river catchment as especially floods risk vulnerable territory. The floods observed there cause serious damages. This indicates that additional preventive and mitigation measures are needed. Part of the measures proposed in the connected to the area Flood Risk Management Plan (FRMP) 2022-2027 envisage changes in the rules for the operation of existing dams. In help of this activity in this material are presented the results of a study aiming determination of the potenti...

The Blato River watershed was determined as especially vulnerable to flood hazards zone regarding the developed Bulgarian Flood Risk Management Plans. With regard to the climate change the number of such hazards increases. To prevent and mitigate the consequences various measures are applied in practice. Some of them are connected to the implementation of already existing engineering solutions. But in case of emergency some untypical temporary solutions are also introduced. In line with the detected severe climate...

Climate and weather play significant role in the urban areas function. They impact on the social and economy life, on the environment and infrastructure, on the biodiversity. That`s why the occurrence of extreme or untypical events is a challenge. Droughts are part of these processes. They are prolonged events that can lead to serious harmful impacts. For this purpose of importance is the becoming of reliable knowledge about such behaviour that can serve as a base for the selection of appropriate prevention and mi...

Floods are exceptional processes, observed in daily life as part of the hydrological cycle or as unusual extreme events. As a result of significant precipitation, snowmelt or/and anthropogenic pressures and technogenic disasters river flow rapidly increase causing an overflow on rivers floodplain with possible damages on the crop, households, economy, infrastructure, social life, etc. Observed consequences depend on the local conditions. They can be negative or insignificant in case of comparatively minor floods, ...

Drought is a phenomenon with a possible negative effect on agroecosystems. It can cause significant impact and damages on crop, when the water balance is seriously affected. But additional harmful effects can be observed also on the whole agroecosystem. This is connected to the land surface and vadose zone, to the physical and chemical properties of soil and water; to the adjacent organisms, etc. To prevent and mitigate the possible dangerous effects of importance is best to know all the specifics of the drought p...

Extreme floods as severe and unusual events are associated to wide range negative consequences such as: extreme floodplain flooding; crop, household, infrastructure and economy damages; social disturbance, etc. Their negative effects in most cases tend to disaster behavior, thus of especial interest is the problem with possible mitigation and prevention measures obtaining. Parts of them are Natural Water Retention Measures (NWRM) that successfully can complement available grey infrastructure. In help of experts in...

Riparian ecosystems play significant role both in the natural and man related activities. They are important part of the hydrological cycle and ecosystem services. They actively support many processes connected to the environment wellbeing, floods retention and mitigation, erosion reducing, river restoration. But under the climate and climate change specifics and anthropogenic works they are under continuous pressure, surely affecting their natural development. To safe and mitigate presented impacts various measur...

Providing the environmentally healthy conditions in rivers is main prerequisite to guarantee the sustainable river ecosystems development. This is connected to implementation of various measures accounting the increasing anthropogenic and climate change impacts. For the purpose on local, national and international level various tools and practices are implemented following the adopted legislation. For the countries of European Union Directive 2000/60/EC (WFD) stipulates main framework for community action in the a...

Urban ecosystems function and maintenance are closely connected to the humans being, their interests and activities. As a result in many cases are observed serious anthropogenic works, causing a significant impact on the natural processes and conditions. Consequently urban ecosystem services become more specific, requiring more individual approaches for the related processes clarification and assessments. The understanding of such implementation recently is under a broad extension. Practices in the area widely inc...
