Journal of Degraded and Mining Lands Management, Journal Year: 2025, Volume and Issue: 12(2), P. 7379 - 738

Published: Jan. 1, 2025

Monitoring total suspended solids (TSS) is essential as sediments impact the environment and human health in various ways. However, TSS data are limited many regions because methods currently applied through situ measurements time-consuming labor-intensive. The study aimed to develop algorithms estimate using derived from UAVs field measurements. Remote sensing technology, such unmanaged aerial vehicle (UAV), was obtain imagery content. These results were then compared with laboratory analysis of in-situ water samples, determined by gravimetric following standard protocols. showed that algorithm developed three-band ratios, blue/green + red/green NIR (near infra red)/green, produces a high R2 (0.70), indicating this combination reliable for use estimating content river section. accuracy red band sediment prediction attributed its spectral signature turbid water, which shows higher reflectance clean water. have potential help managers quickly at relatively low cost.

DEVELOPMENT OF A SIMPLIFIED WATERSHED HEALTH ASSESSMENT FRAMEWORK: A CASE STUDY IN THE UPPER CITARUM WATERSHED, INDONESIA

Journal of Southwest Jiaotong University, Journal Year: 2025, Volume and Issue: 59(6), P. 292 - 312

Published: Jan. 20, 2025

Watershed health assessment is crucial for sustainable water resource management, particularly in regions experiencing increasing environmental pressure. Existing frameworks often rely on diverse datasets, which can be challenging to obtain due the data scarcity many watersheds. This study develops a simplified watershed framework based composite indicators provided by government agencies. Semi-structured interviews, Focus Group Discussions (FGDs), and questionnaire surveys were used identify variables of framework. The Analytical Hierarchy Process (AHP) method was weigh after determining variables. new framework, consisting six indicators—Percentage Vegetation Cover (PVC), Flow Regime Coefficient (FRC), Sediment Load (SL), Water Use Index (WUI), Biochemical Oxygen Demand (BOD), Human Development (HDI), fulfills study’s objective simplifying indicator while utilizing readily available from various official using showed consistent results with existing indicating reliability both approaches despite methodological differences. Although validated against assessments 2018 2021, has only been trialed one watershed, limiting our understanding its broader applicability necessitating further testing additional watersheds evaluate effectiveness comprehensively. provides practical, data-driven tool managers that facilitates decision-making management. Future research should focus validating across varying socioeconomic settings enhance robustness scalability.
