With global warming and over-exploitation of water resources as a result of population growth and other challenges, several studies are being conducted around the world to restore a balance of current water resources and consumption. This research is based on a 366-square-kilometer watershed surrounding the Meghadrigedda reservoir in the...

The purpose of this study is to examine the impact of land-use changes on stream discharge in the Nghinh Tuong watershed (a branch of the Cau river) in Northern Vietnam using the “Soil and Water Assessment Tool (SWAT)” model and GIS. The watershed was 56 percent forested, 30 percent...

Morphometry is a useful tool for identifying the earth’s morphological and hydrological properties. The goal of this study is to determine the morphological characteristics of the Tapi micro watershed. Geospatial inquiry, which includes remote sensing (RS), geographic information systems (GIS), and global positioning systems (GPS), has shown to be...

Coastal flooding is one of the world’s most dangerous natural dangers, impacting more people and destroying more property than any other natural disaster. The purpose of this study was to see how coastal flooding affected residents on Vitoria Island in Lagos, Nigeria. The purpose of this paper is to...

A solid management strategy must start with a detailed awareness of the resources available. Soil is a nonrenewable natural resource that acts as a vital medium for all other living things. Having detailed soil parameters in digital format can help with improved management by allowing for more accurate crop...

The coral reef resources at Biak Island were identified and examined using ground truth data collected in July 2007 and Alos imaging analysis with a 10 m resolution recorded on May 25, 2010, with the assumption that nothing has changed for the past three years. The work uses glint...

In Taiwan, government policy has accelerated the transition from land-based to marine cage culture in recent years. As a result, choosing the right location is a crucial principle and determinant for future success in marine cage culture and sustainable development. It has a significant impact on economic viability by...

Gully erosion has reached alarming proportions in south-eastern Nigeria, prompting the use of geospatial information technology to map a gully erosion site in Oron, Akwa Ibom State, for effective remediation and control. The use of dual frequency Leica GPS 1200 provided ground controls in the vicinity of the gully...

For many years, the River (Sungai) Terengganu catchment in Malaysia has been flooding, causing significant problems for both residents and the environment. The variables obtained from the soil and water assessment tool SWAT, such as land use, soil, and slope, are the parameters measured in this study, which uses...

An agro-ecological (AEZ) zone defines all characteristics of agricultural phenomena such as temperature, rainfall, humidity, soil quality, soil fertility, and crop pattern in a specific area. This research was conducted to establish irrigation distribution, crop pattern, and their relationship. H. Brammer’s research “Agroecological aspects on agricultural research of Bangladesh”...
