MSc Research Proposal Guidelines

5 minute read

Published:

A research proposal is a critical document in the academic journey of a student. It outlines the questions the student intends to explore through their research, showcasing their understanding of the subject area and detailing the methodology they will use. A well-prepared proposal sets the foundation for a successful research project and communicates the significance and originality of the intended study.1

Comprehensive Review on Menstrual Health Management and Waste Disposal in Nepal

4 minute read

Published:

Menstruation is a natural process and a key sign of reproductive health 1. The menstrual cycle in females is a naturally occurring physiological phenomenon after they reach of age. Females go through the natural phenomenon approximately 451.3 times (median number of their lifetimes), corresponding to 34.7 years of menstrual activity, considering an average of 13 cycles per year. The demand for effective feminine hygiene products is surging due to the increasing number of working women and changing socio-economic standards.

Spatial and Temporal Variations of Surface Air Temperature (1962–2022) across Physiographic Regions in the Koshi Basin, Nepal

Published in Journal of Hydrology and Meteorology, 2024

This study analyzed the seasonal and annual trends of maximum temperature (Tmax), minimum temperature (Tmin), and mean temperature (Tavg) across the physiographic regions (Himalaya, High Mountain, Middle Mountain, Siwalik, and Terai) of the Koshi Basin using observed data from 23 stations between 1962 and 2022…

Impact of Climate Variability on Agricultural Productivity and Food Securityin Banke, Nepal: Insights from 1990-2020

Published in Journal of Environmental Science and Agricultural Research, 2025

Nepal’s climate diversity presents complex challenges for its agrarian communities, particularly in regions like Banke where agriculture is highly sensitive to climatic shifts. This study analyzed the period 1990–2020 in Janaki Rural Municipality and found a minor but steady rise in temperature (0.0946°C/year), a significant increase in sunshine hours (15.15 hours/year), and a modest rise in annual rainfall (1.94 mm/year). Statistical analysis showed that sunshine hours were significantly correlated with crop yields (r = 0.417, p = 0.017), while temperature and rainfall were not. Despite adequate overall food production, the district suffers from high dependence on monoculture, rainfed irrigation (93.3%), and limited institutional support. Year-round irrigation markedly improved productivity (7868.63 kg/ha vs. 5450.43 kg/ha). These findings underscore the urgent need for integrated, climate-resilient agricultural strategies to ensure long-term food security in Nepal’s lowland regions….

FLOOD FREQUENCY ANALYSIS USING GUMBEL’S DISTRIBUTION METHOD

Graduate course, Tribhuvan University, College of Applied Sciences-Nepal , Hydrology Department, 2024

The Gumbel distribution, also referred to as the type-I generalized extreme value (GEV) distribution, is a statistical distribution widely used in hydrology, meteorology, and risk analysis. It models the probability of extreme events by focusing on the maximum (or minimum) values drawn from a set of observations or samples. These events often represent rare occurrences such as extreme rainfall, floods, heatwaves, or high winds.

Hydraulic Modelling using HEC-RAS Introductory Class

Graduate course, Tribhuvan University, College of Applied Sciences-Nepal , Hydrology Department, 2024

HEC-RAS (Hydrologic Engineering Center’s River Analysis System) is a powerful modeling software developed by the U.S. Army Corps of Engineers. It is widely used for simulating water flow in natural and constructed channels, performing floodplain mapping, and analyzing hydraulic structures. With its capabilities to model steady and unsteady flow, sediment transport, and water quality, HEC-RAS supports comprehensive river system analysis and decision-making for flood risk management, infrastructure design, and environmental conservation.

A Comprehensive Overview of Statistical Downscaling Model (SDSM)

Graduate course, Tribhuvan University, College of Applied Sciences-Nepal , Hydrology Department, 2024

1 As greenhouse gas concentrations continue to rise, General Circulation Models (GCMs) predict significant changes in climate on global and regional scales. However, these models leave an important question unanswered: How will climate change impact specific locations? Addressing this uncertainty requires a technique known as downscaling—a process that transforms the broad insights provided by GCMs into actionable, localized data.

Introduction to Land Use Land Cover (LULC) Maps

Graduate course, Tribhuvan University, College of Applied Sciences-Nepal , Hydrology Department, 2024

The terms land use and land cover are often used interchangeably, but each has its own distinct meaning. Land cover refers to the physical material found on the Earth’s surface, such as vegetation, urban infrastructure, water bodies, and bare soil. Identifying land cover forms the foundation for activities like thematic mapping and change detection analysis. On the other hand, land use refers to the purpose or function of the land, such as agriculture, wildlife habitat, recreation, or urban development.
