13. Particularities of Drain Liquid in the Small Wetland of Braila Natural Park, Romania

The aim is to highlight the particularities of the hydrological regime and, especially that of the liquid leakage on the lower course of Danube, within one of the many wetlands along the river to correctly quantify the water intake critical periods, for various uses. The current climatic context leads to changes in both liquid flow and land use, vegetation development as well as the risks associated with these changes. Thus, it was desired to quantify and present the way of using the water resources within these wetlands to ensure water volumes during the hot seasons of the year to ensure the volumes of water required for extinguishing the forest fires that can occur in these areas, many of them being natural reserves. It is also the case of the Small Wetland of Braila, a wetland of international interest, being one of the few natural floodplain areas on the lower course of the Danube after the draining of the former inner Delta (Balta Brailei and Balta Ialomitei), which currently preserves complex aquatic and terrestrial ecosystems in a form close to the original one. The significance of this area results from the recognition as a protected area at a national level, European (SCI and SPA) and international (Ramsar site) but it is also noted by the difficulty to establish the water flow, due to the extremely low slopes and the multitudes of channels on the stream.
