Severe droughts have historically plagued Brazil's semi-arid region, leading to mass migrations and significant loss of life. Although these events sparked a unique coevolutionary relationship between humans water systems in this historical narrative remains largely unexplored from hydrological point view. This study delves into the multifaceted history development infrastructure region by compiling analyzing records, official documents, drought literature novels, newspaper reports. Thus, points that societal perception regional memory emerge as feasible pathways heritage toward community resilience droughts. Through analyse, valuable insights are provided for understanding human-water system interactions offering potential lessons other regions grappling with similar challenges.

Small reservoirs play an important role in providing water to rural communities. Increased construction of small mitigate the effects droughts leads a High-density Reservoirs Network (HdRN) reservoirs, which can potentially modify streamflows both dry and wet periods. However, there is lack understanding interannual behavior flow retention impact future increases number mainly for HdRN dryland catchments. This research aims determine possible increase on hydrological networks, evaluating annual flows generated at outlet watershed scenarios with different densities (number per area). The study area was Conceição river catchment (3347 km2) semiarid Brazil. model developed SWAT. obtained appropriate results daily streamflows, values 0.63, 0.81, 0.53% NSE, KGE, PBIAS, respectively. current density region estimated 0.068 square kilometer (res/km2). Eight expansion were defined between 0.1 res/km2 3.0 res/km2. showed that influence runoff reduction mostly occurs probability exceedance 1% 10% month very months high peaks flow. due stronger during years (up 30%) than 8%), it tended consecutive rain (from about 7% first year 20% last worst scenario), may intensify period extended droughts. provides insights variability retention, help resources agencies better prepare hydrologic extremes (droughts floods).

Water environmental capacity analysis and eutrophication assessment of water-supplied reservoirs

Desalination and Water Treatment, Год журнала: 2024, Номер 317, С. 100200 - 100200

Опубликована: Янв. 1, 2024

The protection of water quality in reservoirs, particularly those designated for supply, has garnered increasing attention environmental management purposes. In this paper, the Shuangxikou Reservoir Yuyao was chosen as a case study. pollutant load at various points within reservoir analyzed and its eutrophication level evaluated through combination site surveys regular monitoring. Additionally, model trial algorithm utilized to investigate environment capacity concerning key indicators such COD, NH3-N, TN, TP Reservoir. results indicated that nutrient fell mid-trophic range, with being superior central region compared other areas. However, when target Class II surface mandated by functional zoning, current TN content exceeds acceptable levels. Consequently, targeted measures are imperative enhance reservoir.
