The most commonly encountered particles in the areas of sediment transport, fluidization, sedimentation, etc. are nonspherical. role these can be ascertained only through knowledge drag coefficient and fall velocity. Graphical relationships for determination velocity available literature. graphical less accurate because they subject to errors judgment. Furthermore, cannot used any analytical purposes. In 1954, Schulz et al. collected extensive data nonspherical particles. Based on data,...
Holistic water management approaches are essential under future climate and socio-economic changes, especially while trying to achieve inter-disciplinary societal goals such as the Sustainable Development Goals (SDGs) of clean water, hunger eradication, energy life on land. Assessing resources within a water-food-energy-environment nexus approach enables relationships between water-related sectors be untangled incorporating impacts changes. We use systems modelling explore global change in...
Abstract. The Upper Ganga River basin is socioeconomically the most important river in India and highly stressed terms of water resources due to uncontrolled land use cover (LULC) activities. This study presents a comprehensive set analyses evaluate population growth, LULC transformations, quality nexus for sustainable development this basin. was conducted at two spatial scales: scale district scale. First, data were analyzed statistically demographic changes, followed by change detection...
The Himalaya plays a vital role in regulating the freshwater availability for nearly billion people living Indus, Ganga, and Brahmaputra River basins. Due to climate change constantly evolving human-hydrosphere interactions, including land use/cover changes, groundwater extraction, reservoir or dam construction, water has undergone significant change, is expected further future. Therefore, understanding spatiotemporal evolution of hydrological cycle over its river basins been one most...
Abstract Occurrences of extreme events, especially floods, have become more frequent and severe in the recent past due to global impacts climate change. In this context, possibilities for generating a near‐accurate streamflow forecast at higher lead times, which could be utilized developing reliable flood warning system minimize effects are highly important. This paper aims investigate potential novel hybrid modeling framework that couples random forest algorithm, particle filter, HBV model...
This study investigates the hazardous effect of salinity on plant growth and soil moisture dynamics in root zone. Field irrigation experiments paddy (Oryza sativa L.—basmati variety) with varying levels water (0.5, 5, 10, 15, 20, 25 dS/m) were performed for studying salt stress crop growth. Throughout crop's period, measurements leaf area index (LAI), depth (RD), status zone recorded. For analysis, a numerical model was developed to simulate uptake (RWU) movement zone, accounting osmotic...
The prediction of the sediment loading generated within a watershed is an important input in design and management water resources projects. High variability hydro-climatic factors with generation makes modelling process cumbersome tedious. methods for estimation concentration based on properties flow have limitations attributed to simplification parameters boundary conditions. Under such circumstances, soft computing approaches proven be efficient tool concentration. focus this paper...
Satellite based rainfall estimation techniques have emerged as a potential alternative to ground measurements. The Tropical Rainfall Measuring Mission (TRMM) precipitation, in particular, has been used various climate and hydrology studies around the world. While having wide possibilities, TRMM estimates are found be inconsistent with measurements at locations such southwest coast Himalayan region of India, northeast parts USA, Lake Victoria Africa, La Plata basin South America, etc. In this...
This paper will focus on the challenges associated with algae-based wastewater treatment (ABWWT). To elucidate issue, this review investigate following: (1) microalgal strain selection, (2) characteristics, and (3) effect of various biotic abiotic factors. Mostly, monocultures microalgae are used in (WWT), but microalgae–bacteria consortia have received significant attention recently. Their interaction mechanisms sheer number possible combinations pose a challenge selection. Various types...
The waterscape of the Upper Ganga river basin has reconfigured over last few decades due to rapid population growth, urbanization, and industrialization. It resulted in altered regional hydrology water quality basin. In this study, Soil Water Assessment Tool (SWAT) hydrological model was used investigate effects spatial urbanization on key components study region. Time series Land Use Cover (LULC) maps 1980, 2001, 2012 were prepared using object-based image analysis (OBIA) approach. To...
One of the main mechanisms failure levees is a phenomenon called "piping," which generally begins with formation sand boil at leeward side levee, and has been frequently observed to proceed upstream along base levee through slit formation. The issue most important concern estimate critical head that could promote occurrence piping. Considering flow porous media coupling it Bernoulli's equation tractive stress condition, model developed for head. Using appropriate transformations, proposed...
Abstract In this paper, downscaling models are developed using a Linear Multiple Regression (LMR) and Artificial Neural Networks (ANNs) for obtaining projections of mean monthly maximum minimum temperatures ( T max min) to lake‐basin scale in an arid region India. The effectiveness these techniques is demonstrated through application downscale the predictands Pichola lake Rajasthan State India, which considered be climatically sensitive region. predictor variables extracted from: (i)...
We investigate the performance of existing state-of-the-art rule induction and tree algorithms, namely Single Conjunctive Rule Learner, Decision Table, M5 Model Tree, Stump REPTree. Downscaling models are developed using these algorithms to obtain projections mean monthly precipitation lake-basin scale in an arid region India. The effectiveness is evaluated through application downscale predictand for Lake Pichola Rajasthan state India, which considered be a climatically sensitive region....
Abstract The study was conducted to determine the feasibility of canopy temperature based crop water stress index (CWSI) for scheduling irrigation Indian mustard ( Brassica juncea ). Field experiments were in Hamirpur, Himachal Pradesh (India) during three consecutive cropping seasons (2015, 2016 and 2017). experimental field divided into five plots with different levels treatments on depletion total available soil (TASW) root zone. maximum moisture (SMD) TASW at 10%, 30% 50%, full irrigated...
Pier scour has been extensively studied in laboratory experiments. However, depth relationships based on data at the scale often yield unacceptable results when extended to field conditions. In this study, non-uniform gravel bed and datasets with of median size ranging from 2.7 14.25 mm were considered predict maximum equilibrium cylindrical piers. Specifically, a total 217 collected: 132 literature sources 85 study using new experiments scale, which constitute novel contribution provided by...
