Water Balance of a Small Island Experiencing Climate Change

نویسندگان

چکیده

Small islands provide challenges to hydrological investigation, both in terms of the physical environment and available resources for monitoring. Furthermore, small are generally more vulnerable natural disasters water shortages resident populations. Norfolk Island South–west Pacific, is typical these respects, recent have highlighted lack knowledge required make informed decisions regarding supply. Accordingly, a campaign field measurements analysis was conducted on 2019–2020 period were compared data from 1970’s 1980’s along with climate records some insight into behaviour changes hydrology island over last 50 years. Data indicates that decline rainfall across year balance (13%) combined increased potential evapo-transpiration land cover reduced recharge by 27%. Reduced resulted significant groundwater potentiometric surface runoff (reduced around 57%). Examination majority (70–80%) discharges ocean via cliff or submarine discharge.

Assessing Variation in Water Balance Components in Mountainous Inland River Basin Experiencing Climate Change

Quantification of the changes of water balance components is significant for water resource assessment and management. This paper employed the Soil and Water Assessment Tool (SWAT) model to estimate the water balance in a mountainous watershed in northwest China at different spatial scales over the past half century. The results showed that both Nash-Sutcliffe efficiency (NSE) and determination...

Investigation on Climate Change in Meteorological Stations of Guilan Province and its Impacts on Water Balance

Climate has always been changing during the lifetime of the earth, and has appeared in the form of the ice age, hurricanes, severe and sudden temperature changes, precipitation and other climatic elements, and has dramatically influenced the environment, and in some cases has caused severe changes and even destructions. Some of the most important aspects of climate changes can be found in preci...

Soil water balance and ecosystem response to climate change.

Some essential features of the terrestrial hydrologic cycle and ecosystem response are singled out by confronting empirical observations of the soil water balance of different ecosystems with the results of a stochastic model of soil moisture dynamics. The simplified framework analytically describes how hydroclimatic variability (especially the frequency and amount of rainfall events) concurs w...
