ABSTRACT Understanding the change dynamics of land use and cover (LULC) has a critical influence on hydrological characteristics watershed, economic development, ecological variation, climate changes, been used to resolve current dilemmas between land, water, energy, food sector. It is also essential as observed reflects status environment provides input parameters for sustainable natural resource management optimization. The Chamo catchment undergone large in LULC which increased soil erosion lake sedimentation. In this paper, long-term variations were evaluated using MODIS ESRI Sentinel-2 datasets. As result, significant variation was study area from 2001 2022. Spatial temporal two Based MODIS, grassland dominant class, whereas ESRI, rangeland cropland LULC. result policy-makers stakeholders water management, maintenance, climatic adoption pathways. findings provided evidence that are effective datasets detecting be applied different areas.

Drought forecasting has implications for managing water and irrigation. Currently, with improved technology like artificial intelligence, can be more accurate. In this research, we chose standardized potential evapotranspiration index (SPEI) to characterize drought pattern. To achieve this, the data used was acquired from five meteorological stations in an irrigated Moroccan perimeter 1976 2015. Besides, predict SPEI at two scales (SPEI-3 SPEI-6) inputs combination by exploring capabilities of M5 pruned (M5P) Light Gradient Boosting Machine (LightGBM), along their hybrid model (LightGBM-M5P). assess effectiveness, employed three statistical metrics (R 2 , MAE RMSE). The findings indicated that using a larger time scale analysis enhances ability forecast values accurately. Moreover, revealed M5P demonstrated superior performance compared other studied models.

Abstract We use a Generalized Watershed Loading Function (GWLF) model to simulate streamflow in the Gualí River Basin. The model's performance is assessed using metrics such as percentage of bias (PBIAS), Nash–Sutcliffe efficiency (NSE), RMSE–observations standard deviation ratio (RSR), and Kling–Gupta (KGE) indicate good performance. Furthermore, we analyze projections precipitation several global climate models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6) three shared socioeconomic pathways (SSP1-2.6, SSP2-4.5, SSP5-8.5). Despite uncertainties coarse resolution, our results show that increases mean significantly decreasing trends projected are observed 2015 2099 under SSP5-8.5 scenario. findings suggest an increase long-term mid-flow low-flow. Moreover, this work provides methodological framework for hydrological modeling small tropical river basins, by incorporating data GCMs while raising concerns caveats. This study offers valuable insights into potential effects change on Andean basin characterized volcanic activity significant human impacts. reported here provide useful information future decisions related water supply social, environmental, productive sectors seven towns within catchment.

ABSTRACT We studied the projections of streamflows under climate change scenarios in Upper Orinoco River Basin by using precipitation from 15 global and regional models for period 2020–2099. For this purpose, we calibrated validated a hydrological model with very good performance. Our results show that both streamflow have significant reduction RCP8.5 scenario ranges 5 7% relation to long-term means at end century. The changes variables are not RCP2.6 scenario. Moreover, compute several indicators quantify alterations high-, mid-, low-range flows. suggest main future runoff would be evidenced mid-range low flows, which could increase around ∼5 ∼25%, respectively. These lead hydrological, environmental, ecological balance basin. This work provides information regarding possible effects on one most important river basins northern South America, is pivotal supporting decision-making water supply social, productive sectors.

The B1 tailings dam of Córrego do Feijão iron-ore mine owned by Vale, S.A. company collapsed in 25 January 2019 releasing to the Ferro-Carvão stream watershed (32.6 km2) as much 11.7 Mm3 waste. A major share (8.9 Mm3) has been deposited along channel and margins forming a 2.7 km2 patch. main purpose this study was question whether deposit impacted local water cycle how. Using Soil Water Assessment Tool (SWAT) hydrologic model, balance components 36 response units (HRU) were calculated for pre- (S1) post- (S2) rupture scenarios represented appropriate soil, land use cover. results revealed an increase evapotranspiration from S1 S2, related sudden removal vegetation valley replacement with blanket mud, which raised exposure Earth's surface sunlight hence soil evaporation.
