Accurate estimation of snow-covered area (SCA) is vital for effective water resource management, especially in snowmelt-dependent regions like the Kabul River Basin (KRB). It serves as a reference point comparing expected variations availability driven by climate change, particularly arid and semi-arid KRB. In this study, fractional snow cover (FSC) was estimated across KRB using Landsat moderate resolution imaging spectroradiometer (MODIS) datasets. For purpose, 34 Landsat-8 MODIS...
Effective water and soil management is crucial for crop productivity, particularly in rice cultivation, where poor quality scarcity pose challenges. The response of deeper-rooted grown soils amended with different amendments (SAs) to Internet Things (IoT)-managed alternate wetting drying (AWD) irrigations remains undetermined. This study explores the effects various SAs on DRO-1 IR64 plants under IoT-based moisture monitoring AWD irrigation. A greenhouse experiment executed at Tokyo...
Afghanistan contains an irrigated area of approximately 3 million ha, with the remainder consisting rainfed regions. Agriculture, as primary consumer water resources, contributes significantly to national GDP. The undergoes variation from year year, depending on availability water. To understand variations in actual consumption by agriculture sector, it is vital assess long-term spatiotemporal evapotranspiration (AET) across country. This study assesses AET (1983-2023) and its implications...
Projected snow cover and river flows are important for planning managing water resources in snow-dominated basins of the Himalayas. To quantify impacts climate change data scarce Panjshir River basin Afghanistan, this study simulated present future area (SCA) distributions with model (SM), snowmelt runoff (SRM). The SRM used degree-day factor precipitation gradient optimized by SM to simulate flows. Temperature from eight kinds general circulation models (GCMs) were bias correction. first...
Moderate Resolution Imaging Spectroradiometer (MODIS) products were used in this study which covers a period of 2000–2014. Comparison the SCA derived from MODIS and Landsat NDSI showed significant correlation, resultant coefficient determination (R2) was 0.85. For analyzing trend SCA, Mann-Kendall test applied; results show an increasing non-significant mean annual with Sen's slope value +16.99 (km2/year), winter identified. The 8.92 km2 564 for elevation ranges 5001–5694 m 4001–4500...
A Snow Model (SM) using a temperature-index method was used to optimize the degree-day factor (DDF) and precipitation gradient (PG) for different elevation zones of Panjshir sub-basin snowmelt runoff modelling. The values derived DDF PG were calibrated validated by comparing observed snow cover area simulated SM. Snowmelt Runoff (SRM) simulate daily over hydrological years 2009–2014 optimized SRM accuracy. 0.3 0.9 (cm °C–1 d–1) elevations from 1593 m 5694 m. Meanwhile +0.002 m–1 1593–4000 0...
In the Hindukush-Himalaya (HKH) region, most of population are largely dependent on snowmelt and glacier meltwaters. Snowmelt meltwaters considered to be a key source water resources. We evaluated characteristics snowfall in HKH which elevation ranges from 1593 m 5694 m. Moreover, we estimated spatial temporal Snow Water Equivalent (SWE) distribution combining remote sensing snow model. For this purpose, optimized precipitation gradient (PG) for estimation degree-day factor (DDF) by...
