Soil erosion by water often described as the most worst form of land degradation with serious environmental and socioeconomic ramification, which accelerated human-induced activities impacts agricultural productivity, resources sustainability, ecological conservations. Despite, significant amount research on topic, location-specific soil studies are still limited in Ethiopia, particularly study region. Therefore, this investigates spatial pattern risk map annual loss rate Upper Beles...
The demand for fresh water is constantly increasing among all users. Irrigation in Ethiopia consumes a large amount of extracted from various sources. Hence, efficient use and management are currently the major concerns country. Thus this paper aims to review advancements, challenges, opportunities regarding improving irrigation efficiency Ethiopia. started 1950s with traditional systems. Now modern irrigation, including sprinkler drip practiced some parts showed that even though farmers...
Soil erosion is a major environmental problem that degrades topsoil and agricultural land productivity in mountainous areas such as Ethiopia. estimation critical for the planning of control plans an agriculture-dependent economy. The current study used Revised Universal Loss Equation (RUSLE) model to evaluate spatial distribution annual soil loss sediment yield Rib watershed. main factors affecting include vegetation cover, topography, soil, climate. maps should be produced with these...
The study aimed to evaluate the SWAT and HBV model's responses estimate streamflow in three typical selected watersheds upper Blue Nile Basin, Ethiopia. evaluation was carried out through simulation of runoff watersheds, namely: Gilgel Abay, Anger, Maybar located same calibration validation period were applied for each watershed model with their respective historical records. objective function indicates optimized range parameters during procedure, it gives a good response result, which is...
Soil loss is a continuous ecological problem. The of top fertile soil by erosion creates severe limitations to sustainable agricultural land use, which lead reduced productivity and food insecurity. not affect only agriculture but also causes streams, lakes, dams, reservoir sedimentation. Efforts should be focused decrease risks high rates. This requires prone area identification for urgent conservation plan. Techniques know the spatial variability severity essential improving landuse...
The Tulare Lake Basin (TLB) of California, a vital agricultural hub that covers the southern part Sierra Nevada and Central Valley, is experiencing severe water scarcity due to climate change, rising demand, extensive groundwater depletion. This study leverages an integrated hydrological model quantify Surface Water-Groundwater (SW-GW) interactions in TLB. We focus on understanding seasonal balance trends, variability recharge, impact snowmelt storage. integrated SWAT+gwflow was...
Soil erosion poses a global threat to soil loss, agricultural land deterioration, and crop yield decreases. This paper accounts for the establishment of sustainable planning, methods evaluating rates. The study was conducted based on system complex analysis prioritize in Ribb watershed improve water conservation planning. Several geographical-environmental factors affecting (land use, soil, slope, SPI, TWI, river Proximity, curvature, aspect) considered assess potential risk. information...
Land use and land cover changes in the Jedeb Chemoga watersheds have been detected past 29 years. The study used ERDAS IMAGINE 2015 tools to classify landsat 5 TM, satellite images for preparation of year 1990, 2000, 2009 2018 class maps through likelihood supervised classification techniques. SWAT model has determine seasonal variability streamflow sediment yield due watersheds. To calibrate validate yields as well test performance SWAT-CUP SUFI 2 algorithm was used. outcome showed that...
Engaging youth and women in data-scarce, least developed countries (LDCs) is gaining attention the Sustainable Development Goal (SDG) arena, as using citizen science a multi-faceted mechanism for data collection, engendering personal empowerment agency. Involving these populations powerful synergy that simultaneously addresses Leave-No-One-Behind promise United Nations’ 2030 Agenda, yet most takes place Global North, to LDCs needed. This article highlights four-year, four-location,...
As a result of ongoing human induced or natural factors acting on river channels, banks, and within catchment, alluvial systems change their course morphology over time. The base level changes the backwater effects affect rivers entering static water body. For coastal rivers, planform are highly pronounced at fluvial deltas flood plains. Aggradation, degradation, progradation, meandering, formation islands distributary channels common processes rivers. This study investigates landscape...
<title>Abstract</title> Assessment of the spatiotemporal distribution evapotranspiration is crucial for efficient water resource management, especially in irrigation-dependent regions. This study evaluated actual (AET) Ribb watershed, Ethiopia, via surface energy balance algorithm land (SEBAL) with remote sensing and climate data. The analysis focuses on temporal (daily, monthly, seasonal) spatial variability AET under different uses. daily values ranged from 0 to 10.99 mm/day, mean between...
As a result of ongoing human induced or natural factors acting on river channels, banks, and within catchment, alluvial systems change their course morphology over time. This study investigates planform changes landscape responses Gilgel Abay about 36 km stretch starting from the bridge, near Chimba, to its entrance Lake Tana by using historical images for last 60 years (1957 2020) field observation. The reach was divided in three parts based feature characteristics. From land use cover...
Land use and land cover (LULC) changes in the Jedeb Chemoga watersheds have been detected past 29 years. The study used ERDAS IMAGINE 2015 tools to classify landsat5TM, landsat7 ETM+ landsat OLI / TIR satellite images for preparation of 1990, 2000, 2009 2018 year LULC maps using highest likelihood supervised classification techniques. SWAT model has simulate sediment stream flow determine seasonal variability yield due watersheds. To calibrate validate yields test performance, SWAT-CUP SUFI...
