Summary
This summary is machine-generated.Groundwater in the Metro Hilir Watershed shows moderate to high pollution vulnerability. Key factors influencing this risk include hydraulic conductivity and vadose zone impact, informing crucial water management decisions.
Area Of Science
- Hydrogeology
- Environmental Science
- Water Resource Management
Background
- Groundwater vulnerability assessment is vital, especially in developing agricultural regions like the Metro Hilir Watershed.
- The watershed's intermountain plain setting and rural land use necessitate understanding pollution risks to groundwater resources.
Purpose Of The Study
- To identify, map, and analyze groundwater pollution vulnerability within the Metro Hilir watershed.
- To apply the DRASTIC Landuse Model for a comprehensive assessment of aquifer susceptibility.
Main Methods
- Utilized the DRASTIC Landuse Model incorporating field surveys (well depth, water samples for Nitrate), geoelectric tests (aquifer properties, hydraulic conductivity), and secondary data (rainfall, soil, topography).
- Employed Google Earth Engine for up-to-date land use data (2024) and classified DRASTIC results to define vulnerability classes.
- Validated the model using Nitrate levels and performed sensitivity analysis on key parameters like Hydraulic Conductivity and Impact on the Vadose Zone.
Main Results
- Over 91% of the Metro Hilir Watershed exhibits moderate to high groundwater vulnerability.
- High vulnerability zones are concentrated in the northwest and extend southward, while moderate zones are in the east and southwest.
- Sensitivity analysis confirmed Hydraulic Conductivity and Impact on the Vadose Zone as critical factors affecting vulnerability assessment.
Conclusions
- The study successfully mapped and analyzed groundwater vulnerability, highlighting significant pollution risks in the Metro Hilir Watershed.
- Findings provide essential data for informed groundwater quality management and policy development.
- The DRASTIC Landuse Model proved effective for assessing groundwater vulnerability in this specific agricultural watershed.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
Plane potential flows simplify fluid motion by assuming the fluid to be irrotational and incompressible. These characteristics allow these flows to be described by a velocity potential function, ϕ, representing the flow speed in a given direction, and a stream function, ψ, that visualizes the flow path, both governed by Laplace's equation. These parameters help in estimating flow patterns, velocity distributions, and pressure fields around various hydraulic structures.
