Hydrological investigation and behavior of watershed depend upon geo-morphometric characteristics catchment. Morphometric analysis is commonly used for development regional hydrological model ungauged watershed. A critical valuation assessment constraints has been carried out. Prioritization watersheds based on water plot capacity Piperiya evaluated by linear, aerial relief aspects. attempted prioritization nine sub-watersheds in Hasdeo river basin, which a tributary the Mahanadi....
Uttarakhand, an Indian Himalayan state in India, is famous for its natural environment, health rejuvenation, adventure, and a pilgrimage centre various religions. It categorised into two major regions, i.e., the Garhwal Kumaon, geographically, Bhabar Terai. Floods, cloudbursts, glacier lake outbursts, landslides are hazards that cause highest number of mortalities property damage this state. After becoming full 27th India 2000, developmental activities have increased many folds, which has...
The location of water quality monitoring stations in a distribution system should be such that the network is represented with minimum number stations. present guidelines do not describe how sampling locations are to optimally identified. concept “pathways” helps reducing and shows best set which maximizes demand coverage network. optimal then identified using integer programming. However, dimensionality programming increases manifold increase size for multiple patterns. In this study,...
Mewat (renamed as Nuh) district of Haryana, India having geographical area 1507 km2, comes under semi arid climatic conditions and Aravali hill ranges separates it from Rajasthan state. Groundwater salinization is an emerging threat to water management. Understanding the sources salinization, their relative contributions by different seasonal variability has become priority for planning best practices in management suggesting remedial measures. For identifying direct application relationship...
Watershed health assessment is essential for getting a clear understanding of the present condition watershed systems, which enables effective allocation resources and prioritization management actions in river basin. This study used an innovative framework evaluating data-scarce regions by considering complex interrelations among geophysical, environmental, climatic, anthropogenic factors. The brings together Analytical Network Process (ANP) Fuzzy Logic, addressing challenges managing...
The accelerated pace of urbanization, population growth, and extensive land-use changes has significantly disrupted the ecological balance functionality riverine wetland ecosystems, leading to substantial degradation health. This study evaluates health resilience Upper Ganga Riverine Wetland (UGRW) in India, which experienced significant transformations over past two decades. analysis highlights wetland's various natural anthropogenic stresses its ability sustain critical ecosystem services,...
Urban flooding poses a growing challenge, intensified by rapid urbanization and climate change, which strains traditional drainage systems. This study investigates the application of Low Impact Development (LID) techniques as sustainable solution to enhance urban system resilience. Using Gurugram, India, case study, research evaluates functional structural resilience improvements achieved through LID implementation, alongside Life Cycle Cost (LCC) analysis assess cost-effectiveness.LID...
A number of computer packages have been developed for modeling chlorine decay in water distribution networks. However, there is uncertainty as to the kinetic model that they should use mechanism. This paper explores performance six different models free over 200 bulk samples from a sources. The also presents results surveying longitudinal profile two \Iin situ\N pipe stretches. It concludes network purposes, it generally reasonable assume first-order kinetics and overall decay.
In high-altitude areas, snow cover plays a significant role in mountainous hydrology. Satluj, which is snow-fed river, part of the Indus River system western Himalayas. Snow area (SCA) variability this river basin affects spatio-temporal flow availability and avalanche events. Keeping mind, present study focuses on SCA its relationship with various topographical features such as elevation, slope aspect. The has been carried out upper Satluj Basin basis MODIS Terra (MOD10A2) data from 2001 to...
In the present study, a total of sixty groundwater samples, twenty each for pre-monsoon, monsoon and post seasons 2018, were collected from selected locations in Mewat district Haryana, India. Electrical conductivity (EC) was measured at site dissolved solids (TDS) estimated. Samples analysed anions (chloride, sulphate, bicarbonate) cations (calcium, potassium, magnesium, sodium). Multiple regression analysis performed to analyse data report dominant ions. Piper trilinear diagram Gibbs plots...
This study presents a resilience-based evaluation of an urban drainage system (UDS) under the impact functional and structural failure modes. Resilience based analysis is carried out using SWMM for part Gurugram City Haryana, India. For simulating response, half-hourly rainfall data available from GPM-IMERG was utilized to estimate design storm suitable duration. Sensitivity overcome problem lack in-depth perform model calibration validation. Besides, comparison three different estimation...
