Published: Dec. 22, 2023

The analysis of morphometric parameters plays a crucial role in understanding and managing watersheds, making it fundamental component hydrological investigations. This review paper talks about how important is to objectively evaluate parameters, with focus on the evaluation basins' relief, linear, areal parameters. However, noted that there lack distinct standard classification implication for each parameter some research publications. Furthermore, range categories values have not been adequately addressed previous studies. Many papers state whether particular parameter's resultant value high or low without providing specific ranges associated implications. Also, emphasised accuracy sources digital elevation models (DEMs) affect well works, even when DEMs same resolution are used. existing literature demonstrates determining poses significant challenges. Moreover, verifying first second Horton's laws assessing correlations between lacking articles. main objective this article address these gaps by an in-depth study categorization, including values, level input data quality, products generated, applicability laws. By doing so, aims enhance their ranges, significance application watershed management.

ABSTRACT The provision of an efficient water supply service (WSS) is crucial for the well-being citizens and sustainability cities. This study aims to evaluate performance WSS using results a household survey ranking indicators (PIs) by analytic hierarchy process method. methodology developed was tested case city Taoura (Algeria). A carried out among 340 residents city. showed that majority respondents (70%) were relatively dissatisfied with quantity provided 67% households surveyed rated quality as poor. Then, evaluated according 5 decision criteria 20 PIs. evaluation relative weights are follows: ‘Financial economic’ criterion plays most important role, weight 38.61%, followed ‘Operational’ (24.7%) ‘Physics’ (17.32%). used in this can be reliable tool evaluating developing countries.

Groundwater Environmental Functional Zoning Using GIS and FAHP: A Case Study of an Overexploited Coastal Area in the North China Plain, NCP

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 31, 2025

Unreasonable groundwater exploitation has led to numerous ecological and social issues. Current management practices in China primarily focus on post-event remediation, lacking proactive sustainable solutions. Existing guidelines for function zoning often overlook functions face challenges indicator selection, weight determination, evaluation system construction. Groundwater environmental is scarce Hebei Province, particularly Tangshan City, a national pilot pollution prevention control, where such urgently needed. This study aims establish an index using the fuzzy analytical hierarchy process (FAHP) employ GIS technology spatial analysis delineate zones. The comprises three thematic layers: development potential, current status, quality. weighted sum of these layers reveals: Northern mountainous areas as concentrated water supply source protection recharge zones with robust functions; Central plains dispersed utilization (1 2) moderate Southern coastal unsuitable weak functions. results are validated against actual district boundaries ensure their rationality.

Enhancing Groundwater Recharge Assessment in Mediterranean Regions: A Comparative Study Using Analytical Hierarchy Process and Fuzzy Analytical Hierarchy Process Integrated with Geographic Information Systems for the Algiers Watershed

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 3242 - 3242

Published: April 5, 2025

Groundwater recharge is critical for sustainable water management in water-scarce regions like North Algeria, where climate change and urbanization exacerbate resource challenges, particularly the populous Algiers watershed. This study evaluates groundwater potential using Analytical Hierarchy Process (AHP) its fuzzy extension (FAHP), integrated with Geographic Information Systems (GIS), to map zones. Employing open-source data, AHP FAHP assessed factors such as lithology, slope, rainfall, classifying watershed into high, moderate, low Results show identifying 44.01% (528.95 km2) 52.82% (634.93 3.18% (38.14 potential, yielding similar outcomes (44.35%, 52.47%, 3.17%, respectively). Validation borehole drawdown data confirmed a 73.3% accuracy an AUC of 0.72, indicating moderate good reliability. High zones were concentrated central northern areas permeable soils gentle slopes, dominated region, minimal. concludes that both are effective preliminary assessments, favored simplicity, though excels uncertain data. Limited high-resolution hydrogeological highlight need further refinement, yet approach offers replicable framework managing arid, urbanized facing environmental pressures.

Demarcation of groundwater potential zones in Ponnai sub-basin, Southern India using remote sensing, GIS and fuzzy-AHP approaches

Water Science & Technology Water Supply, Journal Year: 2024, Volume and Issue: 24(5), P. 1529 - 1545

Published: April 22, 2024

ABSTRACT Groundwater is an essential source for household, irrigation and industry needs. The amount of groundwater its quality are rapidly declining because urbanization industrialization. resources in hard rock regions should be handled properly to maximize their utilization. This work aims demarcate the Potential Zones (GWPZ) a part Palar River Basin (Ponnai sub-basin) by combining Remote Sensing (RS), Geographic Information System (GIS) Fuzzy-Analytical Hierarchy Process (FAHP). factors which influence like geology, land use/land cover (LULC), geomorphology, slope, soil, rainfall, lineament density (LD), drainage (DD), normalized difference vegetation index (NDVI), topographic wetness (TWI) position (TPI) considered mapping GWPZ. weightage allocated these parameters on basis FAHP technique obtained potential map was classified as, very poor (13.5%), (21.76%), moderate (31.5%), good (20.66%) (8.54%). GWPZ validated with actual well yield Ponnai sub-basin. research will serve as guideline effective use long-term sustainable management aquifer
