One of the most significant elements of the hydrological cycle is evapotranspiration (ET) as it is a functional part of meteorological conditions. The Visualization of Evapotranspiration at high definition with integrated calibrated (METRIC) model is an example of an image-processing tool that involves the utilization of satellite data in order to compute evapotranspiration as a residual to surface energy equilibrium. Therefore, we used the METRIC model to enumerate ET using 30 m high spatial resolution from Landsat 9 scenes for a study period of 2024 over Cheongmicheon flux tower (CFK) site in Korean peninsula. The METRIC estimations were compared with flux tower measurements obtained from a warm continental climate CFK site for the accuracy assessment. The estimated and measured actual evapotranspiration (AET) at daily scale had good agreement with strong coefficient of determination 0.97. In addition, the trend of ET in comparison to the air temperature was also comparable. This evaluation seeks to enhance the understanding of the strength of the model for mapping the energy balance at the regional scale. Additionally, it is a step towards developing a methodology that can be applied to a wide variety of ecosystems that are heterogeneous.

This research investigates the aquifer continuity and lateral extent in the Dutsinma Basement Complex using the electrical resistivity method, particularly Vertical Electrical Sounding (VES). The study aims to delineate aquifer characteristics critical for sustainable groundwater management. Aquifers are vital for water supply, especially in arid regions. Understanding their continuity and extent is essential for effective resource management. This study focuses on the Dutsinma Basement Complex, characterized by geological complexities that affect groundwater. The demand for clean and portable water increases exponentially with increase population and industrialization. Water is therefore a vital resource without which life will become impossible. The methodology adopted used and interpreted 20 Vertical Electrical Sounding (VES) images obtained using ADMT 300S. The aquifer parameters information estimated from the (VES) were used to produce maps. For effective use of these parameters, iso-thickness and iso -resistivity maps were compared with contour maps of transverse resistance. The agreement between these parameters provided the basis for identification of auriferous zones. The Dutsinma Basement Complex is part of Nigeria’s extensive Basement Complex, characterized by ancient crystalline rocks such as migmatites, gneisses, and schists. These rocks have undergone significant geological processes, including multiple folding and metamorphism, mainly during the Eburnean and Pan-African orogenies. The complex serves as a crucial area for understanding the region’s geological history and structural evolution, providing insights into groundwater flow dynamics. Aquifers within the Dutsinma Basement Complex are vital for local water supply, supporting agriculture and domestic needs. They play a significant role in maintaining ecosystem health by providing water to rivers and wetlands. Understanding aquifer continuity and lateral extent is essential for sustainable management of these resources, especially in areas where groundwater is the primary source of water.

This study explores the water facility service management of Water Supply Providers (WSPs) in Laguna, Philippines in terms of water accessibility to potable water, water reliability, and water adequacy to meet the Local Water Utilities Administration’s (LWUA) performance standards. The study employed a quantitative research method. A gap analysis was the statistical treatment applied. A total of eleven (11) water supply providers in Laguna were the participants in the study. Findings show that water is not accessible, the water supply is not reliable, and the water is barely adequate to meet concessionaires’ demands. The recommendation includes the following: WSPs must conduct a comprehensive assessment of their current operations and prioritize improving their management of water facility service. WSPs must address substantial gaps in their performance as identified in water accessibility to potable water, water reliability for 24/7 water supply and 10 pounds per square inch (psi) water pressure, and water adequacy to meet the water demand of concessioners.

ABSTRACT

PARAMETERS FOR ASSESSING THE SUBSURFACE WATER BEARING STRATA

Journal: Big Data In Water Resources Engineering (BDWRE) Author: Warith Adewale Adebisi and Saminu Olatunji This is an open access article distributed under the Creative Commons Attribution License CC BY 4.0, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited DOI: 10.26480/bdwre.02.2024.38.43

Assessing the subsurface water-bearing strata is a critical task for ensuring efficient water resources management because the worth of underground water cannot be overemphasized. A clear knowledge of its occurrence and characteristics is imperative for resourceful exploitations of natural resources (groundwater). The features of the rocks hosting the underground water in the subsurface, i.e. Aquifer, were treated. Water-bearing layers are classified into aquifer, aquitard, aquiclude and aquifuge. An aquifer is categorized into unconfined, confined, leaky aquifer, perched aquifer and idealized. In addition to the recharge mode, physical parameters that determine the ability of an aquifer to retain and transmit water such as Porosity, Permeability, Transmissivity and Storativity were also discussed. This review also focuses on various techniques used for evaluating the subsurface water-bearing strata. Geophysical methods including the Schlumberger technique of Vertical Electrical Sounding in electrical resistivity and seismic refraction technique were considered as means of assessing the aquifer which provide relative information about the subsurface such as rock type and aquifer zone. Natural and artificial contaminants were finally discussed. This review aims to provide an overview of the various techniques that are suitable for assessing thesubsurface water-bearing strata.

Bangladesh, despite having a subtropical monsoon climate characterized by a waterless winter and warm summer, is one of the peak susceptible countries to climate change. Recently, climate change has garnered significant attention from academics, researchers, and policymakers globally. This study examines the trends in annual as well as monthly rainfall in the Khulna district of Bangladesh over a 20-year period (2003-2022). The aim is to provide current insights into weather patterns, particularly rainfall, in the Khulna district. Secondary data on rainfall were obtained from the Regional Inspection Center (RIC), Bangladesh Meteorological Department in Gallamari, Khulna. Descriptive statistics i.e., mean, standard deviation, and coefficient of variation were estimated to describe the annual and monthly distribution of rainfall. Trend analyses were conducted using bivariate analysis, and simple regression was engaged to assess the relationship between years with rainfall data. The results revealed that monthly rainfall did not follow a consistent pattern, with both increasing and declining trends were detected over the years. When annual rainfall was plotted against years, a negative relationship was identified (y= -12.877x + 27742, R2 = 0.0489). Similarly, mean monthly rainfall showed a declining trend over time (y= -1.0731x + 2311.9, R2 = 0.0489). However, these relationships were not statistically significant. The study underscores the need to implement various adaptation strategies to ensure sustainable agricultural production in the Khulna region. It also suggests the necessity of enhanced monitoring methods due to the instability of temperature and rainfall patterns.

This research work was carried out to evaluate the quality of water from two spring sources in Amurri Community in Enugu State, Southeastern Nigeria. Water samples were obtained from Umu and Ogba springs in dry and rainy seasons, and analysis carried out to estimate physico-chemical and bacteriological indices using standard procedures. Analytical results for both seasons indicated that values for pH, total hardness and total dissolved solids were within World Health Organization (WHO) limits and Nigerian Standard for Drinking Water Quality (NSDWQ) recommendations. Values obtained for iron (Fe) in both dry and rainy seasons (0.90 and 0.80mg/L respectively) in Ogba spring water samples were higher than WHO recommended limit of 0.3mg/L. Fluoride, Cadmium and Nitrate were not detected in any of the water samples in both seasons. Total coliform count in dry and rainy seasons for Umu (9.00 and 140.00 CFU/100ml) and Ogba (10.00 and 150.00 CFU/100ml) spring water sources exceeded the WHO recommended value of 0.00 CFU/100ml; Escherichia coli was not detected in both spring water samples in dry and rainy seasons. Findings from this study indicate that while results for most of the physico-chemical parameters were within regulatory limits, iron (Fe) in Ogba spring water samples, and total coliform count in both Umu and Ogba exceeded WHO recommended threshold. It is therefore recommended that treatment and disinfection of water from springs in the study area should precede consumption.

This experiment was conducted at a private vineyard called El-Wafrah Farm on a desert road to the El-Minya Governorate, Samalout Centre, Egypt. This study aimed to evaluate the effect of ultrasonic treatment (MAXGROW device 4 inches) on the salinization of underground wells in Minya, Egypt, by studying the effect of ultrasound on some physical and chemical properties of irrigation water, and following up on the impact of the treatment process on the chemical properties of the soil at intervals of the treatment process. The results were compared with those of soil irrigated with untreated water. Soil samples were collected from representative areas irrigated with two water sources (well water treated with ultrasound and untreated water). At El- Wafrah Farm, three soil profiles were dug to a depth of 90 cm, and soil samples were collected from successive depths (0–30, 30–60, and 60–90 cm). The effect of saline water treated by the system on soil properties was adverse compared to the non-treated water qualities used in the study. Concerning the impact of the ultrasonic device on soil chemical properties, the results indicated that soil salinity decreased after using the US device compared to normal groundwater. Soil salinity decreased from 1.50 dsm-1 to 0.9 dsm-1 after 45 days; besides, the pH values of the soil were reduced from 8.52 to 7.6 before and after ultrasonic treatment.

During the year 2023-24, an in-depth field experiment was conducted at the Agricultural Mechanization Research Institute (AMRI) in Multan, Punjab province, to explore comprehensively the effect of pruning level on grain yield, Biomass Production, Water use Efficiency and other characteristics contributing to yield of wheat crop. This experiment involved a careful comparison of the performance of various wheat pruning managements, ranging from light pruning, no pruning, moderate, heavy and very heavy pruning. The results revealed significant data: a maximum plant height reaching 96.42 cm, an impressive number of effective tillers per meter of row, estimated at 95.75, a remarkable spike length of 8.89 cm, as well as an exceptional grain yield of 3456.76 kg/ha. Additionally, straw yield was recorded at a high level of 5114.23 kg/ha. Crucially, water use efficiency was calculated at 0.43 kg/cm3, demonstrating optimized management of this essential resource. Among the different pruning managements tested, ultra-heavy pruning, with an 80% reduction in vegetation, emerged as the most favourable treatment, generating significantly better results than those obtained with light or moderate pruning. These results provide appreciated insights for agronomic practices and increasing production in the wheat sector, including importance of appropriate pruning management for maximum production.
