“…The multiannual rainfall value for the entire study period is 425 mm. According to [27,35], precipitations have a break point in 1994. For the period of 1953-1994 we observe a decreasing trend and after it an increasing trend ( Figure 3), and the mean annual precipitation increased from 373 to 531 mm.…”

The aim of this study is to establish the potential effect of changes in climate and anthropic interventions made over time on the hydro-chemical properties of the Techirghiol Lake. Located in the littoral region of the Black Sea, Techirghiol Lake is the most hypersaline lake of Romania—well-known for the therapeutic properties of the saline water and sapropelic mud. Long-term time series of salinity and water level were investigated in relation to the lake water inputs (precipitation, overland flow and groundwater), to chemical parameters (pH, DO and BOD5) and also to the hydraulic works designed and built in the region. The obtained results reveal a degradation of this ecosystem in the period of 1970–1998, when the extensive irrigation practice in the proximity of the lake had a negative effect on the water budget of Techirghiol Lake (an increased freshwater input through runoff and seepage), followed by a major decrease of the lake’s salinity.

DAS Bengkulu mengalami kejadian banjir setidaknya 2 kali dalam setahun pada musim hujan. Banjir merupakan salah satu bencana hidrometeorologi yang dipengaruhi oleh karakteristik fisik dan meteorologi DAS tersebut. Karakteristik tersebut merupakan dasar untuk melakukan perencanaan maupun pengelolaan di DAS tersebut. Oleh karena itu, penelitian ini bertujuan untuk menganalisis karakteristik fisik dan karakteristik meteorologi DAS Bengkulu, sebagai dasar untuk melakukan perencanaan maupun pengelolaan DAS, sehingga dapat meminimalisir kejadian maupun dampak dari bencana hidrometeorologi di DAS tersebut. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kuantitatif terhadap data karakteristik fisik dan meteorologi DAS Bengkulu. Karakteristik fisik DAS yang dianalisis yaitu morfometri, topografi, jenis tanah, dan penggunaan lahan di DAS Bengkulu. Sedangkan karakteristik meteorologi yang dianalisis yaitu curah hujan dan suhu udara di DAS Bengkulu. Hasil menunjukkan bahwa karakteristik fisik DAS Bengkulu mempunyai kemampuan menyimpan air yang rendah, sehingga infiltrasi kecil, namun laju limpasan kecil dan tipe pengaliran aliran sedang. Akan tetapi limpasan cenderung meningkat. Hal tersebut disebabkan oleh perubahan penggunaan lahan hutan yang semakin berkurang, didukung oleh curah hujan yang semakin meningkat, dan variasi suhu udara yang kecil.

Lakes are an important element of the hydrosphere that contribute to the stabilisation of water circulation by providing biodiversity conditions or supporting the development of different branches of the economy. All these properties depend on the longevity of lakes in the environment and the processes related to their evolution. Based on archival morphometric data from historical maps and modern cartographic studies, this paper presents an analysis of changes in their surface area over a period of 100 years. Among 169 lakes, a decrease in surface area was recorded in 156 cases (including the complete disappearance of two lakes); no change was observed in four lakes; and seven lakes increased their surface area. The total surface area of all the lakes has decreased by 11.4% in comparison with the initial state in the early 20th century. The highest rate of decline concerned the shallowest lakes with a maximum depth of up to 5.0 m and lakes with the smallest surface area of up to 20 ha, averaging 24.1% and 22.2%, respectively. The spatial distribution of changes in the surface area of lakes is variable, and at a larger scale it presents no similarities. This suggests that factors determining the rate and direction of changes in the surface area of lakes depend on their individual features and local conditions, which is in accordance with similar studies from the territory of Poland. The obtained results reveal the scale of the changes in the surface area of the lakes, potentially providing important information for authorities in charge of water management in the context of activities aimed at slowing down the disappearance of these valuable ecosystems.
