Rainfall-runoff Relationship in Small Mountainous Catchments
Abstract: An event of stream danger was seen in a little watershed, where precipitation prompted a critical decrease in soil dampness content. This development of soil water can be perceived as sporadic motions as it streams into lower layers. This peculiarity includes a significant measure of water going through the dirt, contributing fundamentally to the general outpouring from the watershed. The precariousnessdriven stream hypothesis can depict this peculiarity, which emerges because …

A Ponder & Sedulousness Of Legion Shale Stabilizing Materials In Aqueous Based Drilling Fluid During The Process Of Borehole Strengthening
Abstract: Drilling fluid used while drilling the layers of shale will have the potential of reacting with water which tends to increase stickiness, induce swelling and promote sloughing of the borehole. This results in the reduction of drilling fluid circulation, increased mud loss, increase in torque and drag, reduction in lubricity. This will ultimately result in the increase of Non-Productive Time (NPT) during drilling which in turn increases Capital Expenditure (CAPEX) …

Determining the Optimal Thickness of Canal Lining for Enhanced Durability and Efficiency
Abstract: The thickness of canal lining plays a crucial role in preventing soil erosion caused by the thrust of water exerted in the canal due to standing water and the velocity of water flow. An optimally designed lining must be robust enough to withstand these forces while ensuring minimal seepage and maintaining the structural integrity of the canal. Various materials are used for canal lining, each with its own advantages and …

pH-Responsive Smart Polymer Nanocomposites for Anti-Corrosive Coatings
Abstract: Metallic corrosion under adverse marine and industrial conditions imposes gigantic financial burdens and risks worldwide. Conventional waterproofing waterborne epoxy has passive barrier protection, but is also inherently microporous, lacking intrinsic repair ability against mechanical damage and thus rapidly decays. This is a critical gap that this work tries to bridge by designing a new pH-responsive hybrid polymer nanocomposite by using polyethyleneimine-tannic acid-cerium functionalized boron nitrate nanosheets with chitosan-capped mesoporous silica …

Green Hydrogen Production Using Air-Conditioner Condensate Wastewater: A Review of Solar-Powered Electrolysis Systems
Abstract: As the world moves toward sustainable and clean energy solutions, growing attention has been directed toward alternative energy carriers such as Hydrogen (H 2 ). Hydrogen is considered an attractive energy option due to its high-density energy and ecofriendly properties. However, most conventional H 2 production methods rely on fossil-fuel-based processes such as steam methane reforming and coal gasification, which contribute significantly to greenhouse gas emissions and environmental degradation. As …
