Recent Trend Determination of groundwater level along with inter-reliant hydrologic components using Mann-Kendall Test,Linear Regression& Geometrical Progression: A case study for Bogradistrict in Bangladesh

author

Abstract:

Groundwater, a special hydrological variable and freshwater resource is completely inter-reliant with hydro-metorological, topographic, land use and hydro-geological components of hydrologic cycle. Trend of hydrologic componentsfor future prediction is attempted to confer in this study using Man-Kendall test, linear regression and geometric progression analysis on recorded data collected from recognize organization of Bangladesh. Bogra district is selected as the study area, which is characterized for fluctuating hydrological components over the years. Temporal distribution & recent trend of dominating hydrologic variables are analyzed and spatial distribution map is presented to discuss localize disparity within the study area. Groundwater abstraction & corresponding recharge reliant with hydro-meteorology and hydro-geology along with land use pattern is attempted to understand in this research. Study conclude for all hydological components related with groundwater is depleting over the recent years with the increase use of water specially for irrigation and domestic needs, but distribution is uneven throughout the Bogra district.

Trend Analysis of Groundwater Level, Using Mann-Kendall Non Parametric Method (Case Study: Tabriz Plain)

Studying the trends of water table in any region especially in arid and semi-arid regions is an important issue. This study focuses on assessing groundwater table changes in Tabriz plain. For this purpose, non-parametric Mann-Kendall test is used. In studing groundwater level the information of 14 pizometric wells in the period of 1991-2013 was used. Significant levels of 1, 5 and 10% were used...

Appendix: Mann-Kendall Trend Tests

Kendall Rank Correlation Let (X1, Y1), · · · , (Xn, Yn) be a bivariate random sample of size n. The Pearson correlation coefficient provides an optimal measure of the degree of association between the X’s and the Y ’s when the sample is drawn from a bivariate normal distribution. The Pearson correlation coefficient is reasonably robust for many other distributions as well. The Kendall correlati...

Comparing Three Regression Models for Reconstructing Groundwater Level Data (A Case Study)

The base for hydrology studies is accurate data. However, the gaps and shortage of sufficient data exist n the most hydrology data such as  underground water data as the most important and cheapest water source,  lack of  data  take places due to various reasons such as Inability to measure and faille to register statistics. Missing data or incorrect statistics, Therefore, estimating the missin...

Mann-Kendall for autocorrelated data

The Mann-Kendall test is a commonly-used nonparametric test for time trend. However, the standard P-values obtained from it are based on an assumption of independence between observations (since the theory is that of the Kendall correlation). However, observations in time series are often autocorrelated: knowing that one observation is larger than the mean may tell you that the next observation...
